Business Survival Strategies that Work

This week we’ve been talking about what it will take to survive in today’s challenging economy. We’ve shared marketing ideas from industry experts and our own playbook that have allowed companies to not only survive past economic downturns but thrive in highly competitive markets. The secret to survival in a bear economy is to develop a corporate attitude that is innovative enough to envision new applications for your products, flexible enough to act quickly when a new opportunity presents itself, and customer-oriented enough to anticipate customer needs and respond quickly to customer requests. Our ability to succeed in these areas has made DJ Products a nationwide leader in the innovative design and manufacture of ergonomic motorized carts and powered cart movers.

Through the example of our own company’s experiences, we’d like to demonstrate how businesses can apply the principles of innovation, flexibility and customer service to survive today and position themselves to thrive tomorrow.

Innovation. Innovators in the material handling field, DJ Products realized the value of ergonomic design before it became a popular cause. We realized that ergonomics was likely to become increasingly important as a worker health and safety issue with the power to drastically reduce health care, insurance, disability and workers’ compensation costs. But beyond that, we saw in ergonomics the potential to improve the speed and efficiency of production across a broad range of business environments.

Flexibility. DJ Products has exhibited the flexibility to imagine and develop new markets for products originally designed primarily for industrial settings. The most compact, light-weight versions of our CartCaddy movers are employed daily in health care and hospitality settings. Their small size and easy maneuverability in tight spaces makes them perfect for crowded hospital corridors and hotel hallways. We’ve found applications for our motorized car/truck pushers in the boating industries and recently designed a specialized version for use by auto racing pit crews.

Customer Service. We’re Old School in our belief that customer service must always be our first priority. We pride ourselves on our ability to customize our products to meet specific customer needs. We’re so convinced you’ll like our products, we offer a free trial program before you buy.

Take a page from the DJ Products’ handbook. Companies that emphasize innovation, flexibility and customer service will survive and can even thrive in these challenging economic times.

Business Survival Requires Effort on Multiple Fronts

Survival is the name of the game these days. Savvy companies large and small are tightening up their production and accounting procedures, taking care of their customers and working to expand their customer and product base. As we’ve discussed this week, some companies are improving their market share through consolidation mergers. Last week we talked about the importance of innovation, flexibility and customer service in surviving in today’s highly competitive market. We’ve also discussed the need to broaden your reach by finding new market opportunities for your products and services. The bottom line is survival in a recessionary economy requires businesses to make a constant effort on multiple fronts. Survival requires continuous effort to maintain current excellence and constant innovation to explore and pursue new opportunities.

Through economic highs and lows DJ Products has maintained its standing as a national leader in the manufacture of ergonomically-designed motorized carts and powered cart movers by blending the old with the new. We have always maintained the highest quality production standards in the manufacture of material handling equipment, but we’ve introduced new, innovation, ergonomic designs to material handling that allow our customers to meet future challenges. Early on, DJ Products identified the growing concern about worker health and safety and the growing expense of ignoring musculoskeletal injuries. We predicted the increasing importance of these issues to employers and their workers as well as government and potential customers and worked to design innovative products that would meet growing demand.

Understanding the value of a satisfied customer, DJ Products has provided superior customer service. But we also understand that customer needs change as business changes. Our material handling products are designed with versatility and flexibility in mind so that they’ll be able to perform multiple functions to keep up with the changing demands of our customers. Lift kits and retrofit kits provide even more innovative flexibility to serve our customer’s needs. DJ Products also has the ability to offer our customers engineer-to-order material handling products to meet their specific needs.

DJ Products has been diligent in finding new uses for our ergonomically-designed material handling equipment. CartCaddies that were originally designed for manufacturing environments are now employed regularly in the healthcare, hospitality and retail industries. Our auto pushers are also being used at truck depots, RV sales lots and boat marinas. Working with our customers, DJ Products is constantly searching for and finding new uses and new markets for our innovative products.

Who Monitors Ergonomic Standards?

With talk that the Obama administration will implement federal ergonomic standards, the question arises: Who monitors ergonomic standards now?

There are a number of governmental and professional groups that write and/or monitor ergonomic standards or guidelines that affect U.S. manufacturers and businesses, most prominently:

Occupational Safety and Health Administration (OSHA)
National Institute for Occupational Safety and Health (NIOSH)
American National Standards Institute (ANSI)
International Organization for Standardization (ISO)

OSHA. Created by the Occupational Safety and Health Act of 1970, OSHA’s mission is to provide U.S. workers with a safe working environment. The federal program is administered through the U.S. Department of Labor, but many states also have OSHA programs. OSHA develops specific workplace standards to protect workers’ health and safety and, through a network of inspectors, polices businesses to see that standards are enforced. OSHA also conducts procedural training and education courses.

NIOSH. Part of the Centers for Disease Control (CDC), a branch of the U.S. Department of Health and Human Services, NIOSH was created by the same act as OSHA. NIOSH conducts research and makes recommendations regarding the prevention of work-related injuries and illnesses.

ANSI. A private non-profit general standards organization, ANSI facilitates the voluntary establishment of U.S. standards in many areas. ANSI does not create standards but serves as a neutral forum for the development of voluntary standards by consensus of industry/business groups. ANSI works to standardize the development, manufacture and supply of U.S. products and services.

ISO. The world’s largest developer and publisher of international standards, ISO is a non-governmental network of 159 countries. Headquartered in Geneva, Switzerland, ISO seeks international consensus on a wide range of product and service issues to facilitate trade.

In the U.S., some states — California and Washington — have their own ergonomics rules. Michigan may join their ranks soon if ongoing efforts to block a new state ergonomics rule fail. Industry trade organization may also champion ergonomic guidelines in their efforts to standardize industry practices.

Presently, ergonomics standards are piecemeal, applying to some industries or occupations but not all. Most often, standards are couched as voluntary guidelines with no penalty for non-compliance. At this time, the U.S. doesn’t have a pervasive, all-encompassing set of ergonomic laws that mandate and describe the use of ergonomics across the breadth of American business, nor is there a universal federal mechanism for requiring companies to implement ergonomic solutions and discipline those who fail to do so. Most U.S. industry watchers predict that this will eventually chance under the Obama administration.

Ergonomic Controls Prevent Carpal Tunnel Syndrome

Constant numbness in the hands, sharp shooting pains in the wrist and up arms, loss of grip strength or even the ability to maintain a grip on objects, loss of feeling in fingers — the symptoms of carpal tunnel syndrome are frightening and the pain is great enough to wake you up at night. Left untreated, the condition is debilitating and can cause permanent damage to your hands.

Because of the serious and debilitating repercussions of carpal tunnel syndrome DJ Products designs all of its material handling equipment with ergonomic controls, handles and handholds. Our goal is to provide ergonomically-designed material handling equipment that protects the health and safety of workers by eliminating the potential for debilitating musculoskeletal injuries, including carpal tunnel syndrome.

Carpal tunnel syndrome is a painful, progressive condition caused when the median nerve, the key nerve in the wrist, is continuously compressed by swollen tissue. The median nerve controls sensations and impulses to the muscles on the palm side of the hand, thumb and all of the fingers except the pinkie. The median nerve runs from the forearm into the hand through a narrow bony passage at the wrist called the carpal tunnel. The carpal tunnel also houses tendons that allow the wrist and hand to move. When repetitive motion activities or repeated stress from pushing and pulling heavy carts irritates wrist tendons, they swell, pressing on the median nerve. The result is numbness, weakness and pain that radiates from the fingertips up the arm.

When workers continue to perform daily tasks that irritate wrist tendons, pressure on the median nerve becomes constant, eventually causing permanent damage. Without nerve support, the individual gradually loses fine motor and may even lose gross motor control of his hands and fingers. He may lose the ability to sense hot and cold. Muscles at the base of the thumb atrophy, and hands can become deformed. Left untreated, carpal tunnel syndrome can cause life-altering disability.

Repetitive motion activities on the job and strain from pushing and pulling heavy equipment are the leading causes of carpal tunnel syndrome in the U.S. According to the National Institute of Neurological Disorders and Stroke, in a 1998 study 3 out of every 10,000 U.S. workers were affected by carpal tunnel syndrome. On average, each worker missed 10 days of work and incurred medical bills of $30,000. Treatment of chronic cases requires surgery and an average 6 to 8 weeks for recovery. Utilizing equipment with ergonomically-designed controls and handles can effectively eliminate the risk of carpal tunnel syndrome.

Safety Is No. 1 When Choosing Material Handling Equipment

Productivity and safety are the two top concerns when business owners buy material handling equipment, with safety being paramount. Unsafe equipment will drag down productivity, while safe equipment will enhance productivity. To handle materials safely, loads must be under the operator’s control at all times. Load capability and handling, maneuverability, control placement and design, wheel placement, tire composition, operator line of sight — there are a whole host of design elements that determine the safe operation of material handling equipment.

Manufacturing material handling equipment that is as safe to use as it is easy to operate drives the design of DJ Products’ material handling equipment. Our products are ergonomically designed to take the physical strain off workers’ muscles, allowing them to work more efficiently and more comfortably. By making equipment adaptable to the worker, ergonomic design allows workers of various body types, ages, and physical skills to perform on an equal footing. Ergonomic design maximizes employee performance by eliminating awkward work postures that lead to the tired and cramped muscles that erode job performance and can lead to injury and disability. When workers are forced to contort their bodies into less than optimal postures to operate equipment, muscles become more quickly fatigued. Not only does fatigue lead to slower task production and longer and more frequent breaks, it increases the risk of injury. Ergonomic design eliminates these problems and ensures each worker a safe and comfortable work environment.

To maximize operator control and line-of-sight, DJ Products’ material handling equipment is designed so that the operator walks or rides behind the loaded equipment. This affords the operator maximum visual sight lines to ensure plenty of time for maneuvering and safe stopping, particularly in crowded or heavily trafficked environments. Conveniently-positioned, ergonomically-designed controls allow easy operation and instant safe stopping power of DJ Products’ battery-operated and motorized carts and cart pushers.

A unique safety feature of DJ Products’ carts and movers is our strategically-designed mover arm that allows our cart movers to pivot a full 180 degrees under the arm once it is firmly attached to a cart or piece of equipment. This allows the operator to turn and maneuver carts and equipment safely without risk of jackknifing the cart while carrying a heavy load.

Preventing Overexertion Injuries

Pushing, pulling and lifting are the three tasks most frequently performed by American workers. Overexertion during the execution of these tasks is responsible for 25% of all workplace injuries in the U.S., according to the National Safety Council. In fact, the National Institute for Occupational Safety and Health (NIOSH) reports that one in every 200 workers suffers an overexertion injury. Annually, these musculoskeletal injuries cost U.S. business over $1 billion in direct compensation costs and more than 12 million lost workdays.

Repeated studies have proven that ergonomically-designed equipment can significantly decrease costly musculoskeletal injuries in the workplace. Ergonomics is the science of adjusting the equipment to the size and capabilities of the worker. Ergonomics emphasizes worker safety and comfort with the goal of reducing worker fatigue, discomfort and injury. The use of ergonomic equipment allows businesses to maximize the efficiency and productivity of their workforce while protecting workers’ health and safety.

The consequences of neglecting ergonomics are staggering. Workplace injury and illness cost U.S. businesses $171 billion annually, more than cancer or heart disease, the country’s two biggest killers. According to the American Medical Association, more than 13.2 million workers a year suffer a non-fatal workplace injury, many of them preventable musculoskeletal injuries.

Statistics compiled by the U.S. Department of Labor reveal that workers’ compensation claims cost U.S. businesses $60 billion a year. More than 50% of those claims are for back injuries caused by pulling, pushing or lifting, tasks, according to the National Council on Compensation Insurance. One in five disabling workplace injuries affects the lower back. According to the Bureau of Labor Statistics, more than 1.75 million U.S. workers each year succumb to a back injury that involves lengthy and costly medical and rehabilitation treatment, in addition to a considerable number of lost workdays.

Utilizing ergonomically-designed motorized carts and powered movers to assist workers with pushing, pulling and lifting tasks can save a business thousands of dollars — $4 for every dollar invested, according to a 2008 study reported in the New Hampshire Business Review — in decreased medical, insurance and disability costs resulting from musculoskeletal injuries. DJ Products, a national leader in the manufacture of ergonomically-designed electric carts and movers, specializes in providing affordable ergonomic solutions to material handling applications.

Body Posture Plays Significant Role in Ergonomic Design

Body posture affects the amount of force that must be exerted to move and maneuver industrial carts and equipment. The human musculoskeletal system functions like a complex system of mechanical levers. Posture determines the positioning of our joints which, in turn, determines the reach of each muscle and the force needed to exercise it. Ergonomic design seeks to produce maximum force from each exertion by optimizing body posture. In creating a more efficient piece of equipment, the goal of ergonomic design is to minimize wear and tear and the threat of injury to the human body.

Optimal body posture generally changes a piece of equipment is moved. The horizontal force necessary to put equipment in motion gives way to a more upright stance as less force is needed to keep it in motion. Handle placement can affect the amount of horizontal push a worker is able to supply. Any angle above or below the horizontal plane will diminish the amount of force a worker can produce. The greater the angle, the less direct force can applied to horizontal movement. Due to variations in worker size, adjustable handles or multiple handholds will allow optimal force production for a greater percentage of your workforce.

Foot positioning can also have a significant impact on the amount of force a worker can produce. The greatest push force is generated when the body is in a lunging posture with feet separated, one foot some distance ahead of the other. Because this position places the rear foot beyond the body’s center of gravity, it unbalances the body, placing workers at increased risk for falls and injury. The risk of serious injury increases if push force must be executed on either an incline or decline.

The use of electronic or motorized carts eliminates the burden of force and the risk of potential injury from your workforce. Equipment rather than the worker’s body provides the push force to necessary initiate and maintain movement. Optimal force can be applied regardless of worker size and strength, maximizing the efficient use of your workforce and optimizing task completion.

Specialized Carts Designed for Hospital Use

Any nurse, therapist, aide or worker will tell you that working in hospitals, nursing homes and similar settings is back-breaking work. Workers are on their feet all day long and constantly on the move. There’s a lot of bending, stretching, reaching, pushing and pulling involved — all activities that can strain and stress muscles, tendons, ligaments and joints and lead to potentially debilitating musculoskeletal injuries.

Most hospital workers, who typically work 12-hour shifts, will tell you that workloads are already heavy. No one appreciates the extra burden imposed when a fellow worker calls in sick with a strained back. Musculoskeletal injuries aren’t a quick 24-hour fix. They entail days to weeks and sometimes even months of treatment and physical therapy. Returning workers must often be assigned to light duty jobs or face re-injury if they attempt their former activities. The lost man-hours, reassignment and rescheduling needs can create significant problems, both for administrators and fellow workers. The high costs of medical treatment, insurance and workers’ compensation make the elimination of musculoskeletal injury risk a high priority for hospitals, nursing homes and similar facilities.

The heavy pedestrian traffic, narrow corridors and constrained spaces typical of hospital settings present a unique challenge in designing ergonomic equipment to take the physical burden off medical workers. That’s why so many tasks in these settings are still performed manually, despite the risk of injury. To answer the unique needs of hospital settings, DJ Products has created a specially designed line of motorized cart pushers. We have produced a line of small, extremely maneuverable caddies that are designed to carry lighter loads. The quick and easy maneuverability of these carts makes them ideal for use in confined spaces and in areas with high pedestrian traffic.

The CartCaddyLite is the smallest, most maneuverable tug available on the market today. This battery-powered electric tug can push or pull up to 1,000 pounds and is versatile enough to handle a variety of cart types, including dollies, hand trucks, laundry carts, hospital carts, maintenance carts and hospital beds. Click here for CartCaddyLite specifications and a video demonstration of this versatile cart puller/pusher.
The CartCaddyShorty has enough power to handle carts and equipment that weigh 3,000 to 20,000 pounds. This battery-powered electric tug is a powerful workhorse that can transport heavy equipment, food carts, laundry bins, x-ray machines, respiratory equipment, dialysis equipment, oxygen canisters, wheelchairs, IV poles, even bags of garbage.

Failing Auto Industry a Warning to U.S. Manufacturers

The auto industry bailout is in peril and may be beyond saving. The demand by Senate Republicans that the UAW agree to slash auto workers’ salaries to compete with their Japanese counterparts may have put “paid” to the deal approved by the House. If any of the Big Three automakers fail, the fallout is expected to send our already troubled economy plummeting even further downward. The strain on unemployment and social resources, the trickle-down effect on the industry’s supply chain, irreparable erosion of America’s already diminished manufacturing base, a drastic decrease in consumer choices — we’re going to be paying for Detroit’s poor management and poor choices for years to come. There is no silver lining here, but there are important lessons to be learned.

While the issues are complex, experts have boiled the U.S. auto industry’s woes down to four basic problems: failure to embrace the future, lack of flexibility, failure to effectively manage labor, and failure to rein in expenses. These are the basic cornerstones for success in any business.

Embrace the future. Globalization of the economy, resource depletion, and the speed at which technology changes will continue to bring vast changes to industry and manufacturing. Companies with the vision to position themselves to meet future needs by taking advantage of these changes will prosper. Those like the U.S. auto industry who don’t will eventually fail.
Maintain flexibility. Rapid response will separate the men from the boys. Companies with the mental, financial and physical flexibility to react quickly to changing market needs and strictures will prosper most.
Manage labor. U.S. labor costs are the arena in which America is least competitive globally. An inability to manage labor demands is one of the core causes of Detroit’s failure. To remain competitive into the future, American businesses and the workers that depend on them for their livelihood will need to address this issue and both sides may need to moderate their expectations.
Rein in expenses. Maintaining tight control over expenses and instituting proactive accounting practices are essential for survival in a poor economy. But maintaining these practices as the economy improves will give you the financial flexibility to reach future goals.

DJ Products ergonomically-designed, powered carts and tugs can position you to meet the future successfully. On Monday, we’ll tell you how.

Human Factors Affect Push-Pull Equipment Design

Humans come in all shapes and sizes. And that’s the challenge in designing safe, effective ergonomic equipment. There is no such thing as “one size fits all” when you’re designing equipment that will be used by a diverse workforce. However, there are a number of specific human factors that affect a person’s ability to execute a pushing or pulling task. Ergonomics strives to incorporate these factors into equipment design to ensure that workers can safely and effectively complete required tasks.

Biomechanics use gender, body size (anthropometry), posture and push/pull force to calculate muscle force requirements and bone/joint compression forces. Biomechanics are useful in examining exertion, but generally fail to consider dynamics, repetition and duration of the task.
Physiology considers physical work capacity (a measurement of maximum aerobic capacity) and fatigue, particularly in tasks that are repetitive, fast paced or that require forceful exertion. Since each person is unique, his or her physical work capacity will be different. Factors considered include age, fitness, gender and maximum heart rate, as well as the energy demands and duration of the job. Physiology also factors in the necessary dissipation of body heat as affected by clothing, temperature, humidity and air movement. In designing equipment, ergonomic engineers consider the expected user population and generally design for the least physically capable individuals within that population.
Psychophysics takes human perception of the task into account. It evaluates the type, frequency, distance and hand height of the task, as well as the type of force required to execute the task. Also considered are the gender and characteristics of the average worker who will perform the task.

By considering these three types of human factors, ergonomic engineers strive to design an electric tug that can be safely and efficiently used by workers.
