Taking the Pain out of Cart Retrieval

Nearly all large retail establishments have a multitude of shopping carts to serve their customers and invariably at several points throughout the day; many of those shopping carts are strewn about the parking lot.  This leaves the burden of cart collection on the employees of the establishment, and while its good to have job security, especially in this day and age, this particular duty is probably among the least favorite of many retail employees.

Carts get left in the parking lot regardless of the weather or temperature outside, leaving employees having to go out in the rain, snow, sleet and freezing temperatures to perform this high labor duty.  Collecting just a few carts at a time could make the process take far too long, and trying to collect a dozen all at once could lead to an unnecessary injury – manual cart collection, especially in less than favorable weather, is a lose-lose situation.

A cart retriever from DJ Products can take all of the hassle out of collecting shopping carts by removing the stress and strain on the employee and allowing the task to be performed at a much faster pace.  DJ Products cart retriever can easily handle a line of up to fifty shopping carts, allowing an entire parking lot to be cleaned of carts in a fraction of the time it would take to perform the collection manually.

The Cart Retriever makes this once dreaded job much safer and much easier and it frees up many more man hours for employees to attack other jobs inside the store to potentially create more revenue.  When employees aren’t pre-occupied with cart collection, more product can make its way on to the shelves, more customers can be served and the establishment can be kept organized and clean.  Increasing productivity in the workplace without risking employee safety is the best way to increase profitability and the Cart Retriever does just that.

Ergonomics = Respect for Workers

Companies that value and respect their workers are proactive about ergonomics, said Peter Budnick, PH.D., founder, president and CEO of Core 3, Ergoweb and Ergobuyer, at a recent material handling conference. “A well formulated ergonomics strategy supports and accelerates continuous improvement in any organization, facility or supply chain.”

Integration of ergonomic practices and equipment into manufacturing and business operations improves productivity, waste reduction, quality control and safety. Ergonomics can operationalize a company’s respect for people, said Budnick, who added that many companies misunderstand ergonomics and therefore don’t recognize its value. He considers ergonomics “essential in an effective continuous improvement system” in any business or industry. 

Ergonomics takes a human-centered approach to task and tool design. It recognizes differences in the individual characteristics and capabilities of workers and strives to accommodate those variables in the design of equipment and structuring of tasks. The goal of ergonomics is to prevent soft tissue, repetitive motion, repetitive stress and musculoskeletal injuries. Nearly half of all lost work days can be attributed to musculoskeletal injuries. These injuries cost U.S. industry more than $61 billion per year in lost productivity and an additional $20 billion in annual medical and workers compensation benefits.

The value of respecting workers has been proven time and again. Toyota has made it a pillar of its business execution plan. When workers are valued, productivity and quality increase while injuries and negativity decrease. Implementation of an ergonomics program is an important way to show workers that you respect them and value their health and safety. In formulating an ergonomics program, evaluate tasks, equipment and work environment for the following factors:

  • force applied
  • awkward or fatiguing postures
  • repetition or frequency
  • duration, both of the task and the number of times per day it is performed
  • vibration
  • contact pressure
  • velocity of movement
  • environmental factors including lighting, temperature, noise, etc.

The goal of ergonomics is to eliminate the discomfort and stress these factors cause workers. On the DJ Products website, we provide a handy Ergonomic Load Calculator that can assist you in evaluating the force needed to move loads in particular workplace environments. Our experienced staff can assist you in designing ergonomic solutions to that will benefit your workers and increase productivity.

Use a Tow Tugger to Transport Carts Safely

DJ Products offers tow tugs like the CartCaddy Shorty that are designed to help workers move heavy carts and equipment efficiently and safely. Our motorized cart movers increase productivity by reducing the number of operators needed to move a heavy cart since tuggers like the CartCaddy Shorty can be operated by one employee.

One employee can move heavy carts and equipment safely with the CartCaddy Shorty because it attaches to the swivel-castered end of a cart and provides the pushing and pulling power necessary for easy turning and intricate maneuvering. It has a variable speed twist grip for forward and reverse directions and can be operated at speeds from from 0 to 3 mph. This means that it can keep up with the operator so he or she will not become frustrated or need to try to yank it or force it to move. Operator frustration such as that can cause problems and our equipment was designed to avoid those kinds of situation.

Another important feature of the CartCaddy Shorty is the safety stop. When the safety stop is activated, the machine stops immediately to prevent any possible injury. We design our equipment to be as safe as possible and to prevent strain, however there are situations that we cannot foresee. This is why an operator has the option of stopping the tugger immediately if necessary.
Sufficient power can also be a safety concern since you do not want to buy equipment that stops working in the middle of the job. The CartCaddyShorty Power Tugger can be operated continuously for 16 hours before you need to recharge it.

New Race Car Pusher Zooms into Nascar Pits

You have to love Nascar. The roar of the engines, the flashing colors, the intense concentration of drivers hurtling around the track at speeds we only wish we could achieve with our rather pedestrian family car. We marvel at the balletic precision of the pit crews as a car zooms in and screeches to a halt, tires smoking. Like attacking locusts, the crew descends on the car, jacks pumping and pneumatic drills whirring, bouncing tread-bare tires off and new ones back on. Then with a roar, the car is off again to join the fray.

What we don’t see is the back-breaking labor behind the scenes. Before and after races, these race cars must be muscled in and out of trailers, pushed around service areas for fine tuning and repair, shunted across huge expanses of tarmac for inspection or testing, and maneuvered into the pit — all manually. Can you imagine the chaos if all those high-powered machines went lurching around with engines roaring? Until race time, the only power used to move these sleek racers is human muscle. And since human sinew and tendons are no match for more than a ton of steel, injuries are common.

DJ Product’s RaceCarCaddy keeps the risk of injury on the track and out of the pit. This battery-powered auto pusher allows a single crew member to expertly move and maneuver a heavy race car in the pit or staging area without risk of injury, freeing other crew members for other service tasks. Our RaceCarCaddy is a specialized version of our popular ergonomically-designed car and vehicle pusher developed especially for the race car industry.

The RaceCarCaddy is capable of moving 5000 pounds. Made with a strong tubular steel frame, this battery-operated vehicle pusher features a variable-speed handlebar twist grip to eliminate carpal tunnel syndrome, can go from 0 to 3 mph in both forward and reverse with adjustable acceleration braking, and features non-marking push pads to protect those snazzy paint jobs. Powered by three 12-volt batteries, this powerful vehicle mover comes with an onboard automatic charger, Hoosier slick racing tires and much more.

Specialized options are also available for the RaceCarCaddy, including an operator ride-along kit, foam-filled tires, snow and ice tires, flashing light, safety horn, maintenance-free batteries and a heavy duty motor/transaxle power upgrade that allows this caddy to push cars and trucks up to 50,000 pounds. Your RaceCarCaddy can be customized to match your race car and include your sponsor’s logo.

Use Ergonomics to Improve Lifting Safety

Lifting and carrying are the two material handling tasks that result in the greatest number of worker injuries each year. (See our May 14 post on tips for ergonomic carrying.) Applying ergonomics to material handling tasks that involve lifting reduces the need for reaching and bending and the injury-producing stress those actions can place on the back and shoulders. Ergonomics also strives to reduce the amount of effort and force necessary to perform lift tasks.

Calculations of lift force involve both the amount of weight to be lifted and the time period over which the average worker can lift that weight without risk of developing lower back pain. Under ideal conditions, the maximum weight a typical healthy worker can lift with two hands over an 8-hour period is 51 pounds, according to the National Institute of Occupational Safety and Health (NIOSH). However, a number of variables can significantly reduce the maximum lift weight. 

To decrease the potential risk of injury from lift tasks, both overall work flow and individual work tasks should be evaluated to eliminate unnecessary lifting. Where lifting is necessary, ergonomically designed equipment can be used to facilitate many lift tasks. Workers can also be trained to use ergonomic principles in performing lift tasks to minimize potential injury.

To decrease injuries caused by lifting, follow these suggestions:

  • Use ergonomic electric scissor lift tables and power hoists to lift and lower loads where possible to minimize manual lifting.
  • Minimize the distance materials must be lifted or lowered.
  • Use adjustable powered tugs that allow workers to position lift loads at the appropriate height for maximum lifting power.
  • Tag unstable or heavy loads to alert workers. Promote team lifting of such loads to minimize potential worker injury.
  • Test loads for weight and stability before lifting.
  • Reduce load weights and balance loads to facilitate lifting without injury.
  • Rotate workers between lifting and non-lifting tasks or have workers alternate lifting with non-lifting tasks to avoid over-straining muscles. 
  • Reduce the frequency of lifting and amount of time workers perform lifting tasks.
  • Provide clear access to materials to be lifted to prevent awkward reaching, bending and twisting during lifting.
  • Provide secure grips on materials to be lifted.
  • Provide sufficient foot traction with the floor to increase worker stability during lifting.

What to Look for in Ergonomic Design

You can’t squash a square peg into a round hole. In effect, that’s the idea behind ergonomic design. Instead of trying to contort human bodies to work tasks, ergonomic design seeks to fit products, tasks and environments to the people who use them. The result is increased productivity, decreased expense and greater worker safety. Definitely a win-win scenario for business and workers.

Ergonomics factors the human element into work tasks by taking into consideration physical capabilities such as force, posture and repetition. The psychological aspects of a task may also be considered, including mental loading and decision making. Ergonomic design may call upon the expertise of engineers, safety professionals, industrial hygienists, physical therapists, occupational therapists, nurse practitioners, chiropractors, physicians and the workers themselves.

In creating ergonomically designed equipment, both typical tasks and work sites are evaluated. By identifying potential risk factors and conditions, equipment can be engineered to reduce those risks. Ergonomic design must account not only for a range of work site conditions, but also for an even broader range of potential workers. After all, workers come in all body types. Height, weight, physical condition, physical and mental ability, age and sex must all be considered in designing ergonomic equipment. Ergonomic design generally allows equipment to be adjusted to allow for individual differences. 

DJ Products manufactures quality ergonomically designed electric and motorized carts. On our website, you’ll find a handy Ergonomic Load Calculator you can use to estimate the amount of horizontal force necessary to move loads in your particular business environment. The experienced staff at DJ Products can assist you in selecting ergonomically designed equipment that meets the needs of your business. Contact a DJ Products ergonomic design specialist today.

Michigan Poised to Adopt Ergonomic Standard

A new initiative in Michigan could presage an expected federal push to mandate ergonomic equipment and procedures in business and industry. Last week, Michigan state regulators unanimously voted to advance a proposed state-wide ergonomic standard. Unless blocked by the state legislature, as a similar initiative was in 2006, the new standard could take effect this year.

If implemented, Michigan would follow California, becoming the second state in the U.S. to implement its own ergonomic rules. While the federal government has established ergonomic guidelines for many industries, they are currently voluntary, although that is expected to change. During his campaign, President Obama promised to enact tougher workplace safety standards early in his administration.

With the unanimous support of the state’s General Industry Safety Standards Commission and the Occupational Health Standards Commission, Michigan political analysts believe that, this time around, any efforts to block the proposed state-wide ergonomic standard will fail. Supporters of ergonomic equipment and procedures point to their proven record in reducing preventable injuries that each year cost businesses millions of dollars in medical and insurance costs, worker’s compensation claims, and lost man-hours. According to Michigan’s Worker’s Compensation Bureau, about 40% of worker’s compensation claims paid in 2006 and 2007 were related to preventable ergonomic injuries.

The proven ability of ergonomically-designed material handling equipment to prevent repetitive stress and musculoskeletal injuries and reduce concomitant production and human resources costs is well documented by the U.S. Department of Labor and the Bureau of Worker’s Compensation. While opponents have expressed concern that Michigan’s ergonomic imperative will increase the cost of doing business in a state already struggling to survive economically, statistical and experiential evidence show that return on investment in ergonomic equipment is generally realized in the first year of ownership.

Michigan’s proposed standard would “assess risk factors that may contribute to work-related musculoskeletal disorders and establish a minimal rule for training,” according to the Michigan Department of Energy, Labor and Economic Growth. The standard will only apply to general industry businesses, not construction. Public hearings must now be held by Michigan’s Occupational Safety and Health Administration (MIOSHA) before the rule can be formally adopted, possibly as early as this summer.

Ergonomics Can Help Decrease OSHA Reporting

One way to keep your company out of OSHA’s crosshairs (see our previous post) is to embrace ergonomics. Using ergonomic principles to design equipment, plan workstations and structure task performance has been proven to significantly decrease worker injuries and fatalities. Businesses reap additional benefits in decreased medical, insurance, disability and worker’s compensation costs. Fewer man-hours are lost to injury where ergonomics are practiced.

Lifting, repetitive motion, overextension and overexertion are common injuries in material handling, warehousing and logistics environments.  Injuries to the back, neck, shoulders, hands and wrists can result in serious, long-term disabilities — and the hefty medical and insurance expenses that go with them. Back injury is the most cited injury in worker’s compensation claims. Many of these injuries are preventable when ergonomic equipment and strategies are employed.

Making an investment in ergonomics is making an investment in your workforce. Demonstrating concern in your employees’ health and welfare has a direct and highly positive effect on worker morale and productivity. DJ Products can help you determine your ergonomic needs. Use our handy Ergonomic Load Calculator to estimate the force needed to move loaded carts, castered equipment and wheeled machinery. Our experienced staff can help evaluate your ergonomic needs and recommend ergonomically designed carts and tugs geared to improve the safety of your facility and protect the health of your employees. Your initial investment in ergonomics will be quickly balanced by savings in medical, insurance and disability expenses. Visit our website today for complete information.

Working in the Crowd

Some positions require material handling equipment that is powerful enough to tackle heavy loads reliably, but that is small and easily maneuvered to where it can weave in and out of tight corners among crowded areas.

Consider feeding times in places like hospitals, nursing homes and institutions – many of the residents of these environments are incapable of visiting a cafeteria so there food must be delivered.  In buildings that have potentially thousands of residents who are on a tight schedule, feeding time can be a very busy time.  Individually carrying meals to the residents is completely impractical, but large manual carts could be too cumbersome to move throughout hallways where there will be residents/patients and other members of the staff constantly moving.

These aren’t atmospheres where the hallways can be tied up for extended periods of time for food service; meals need to be delivered on schedule, quickly and without blocking access to other areas of the unit.

This is where equipment like the Parts CaddyLite from DJ Products becomes a necessity.  This super efficient, quiet and powerful little cart is easy enough to maneuver that even crowded hospital hallways are easily navigated.  Food and supplies can be easily delivered without interfering with other necessary operations and without causing any excess noise that could potentially disrupt residents or patients.

The Parts CaddyLite is easy to use and designed with both efficiency and safety in mind.  With a variable speed adjustment, the job can be completed as quickly as is necessary, but without putting anyone’s safety at risk and the battery is capable of lasting for two whole shifts on a single charge – so reliability will never be an issue.  If your business requires that your employees be capable of delivering goods on time, without fail in an environment that has close quarters and crowds – the Parts CaddyLite will deliver every time.

Ergonomic Design Reduces Equipment Injury Risk

In our last post, we discussed the results of a three-year study of musculoskeletal injury risk factors in the trucking industry. While that study focused on long-haul truckers who are forced to maintain the same postures for hours at a time and the toll such limited activity takes on the body, the study provides an instructive lesson for any business owner who uses material handling equipment to move materials and products in the workplace. Any time workers spend long periods of time performing similar tasks, any time workers repeat the same physical movements during their shift, any time workers must adapt their bodies to “fit” the equipment they operate, any time workers must use their own body muscles to move or maneuver materials, the risk of sustaining damaging musculoskeletal injuries increases significantly. Ergonomics is the solution.

The recent study by Atlas Ergonomics reported in EHS Today online evaluated musculoskeletal injury risk factors for commercial truckers by demographics, height, weight, age and gender. Risk factors significantly increased whenever drivers had to stretch or contort their bodies to reach and operate controls. Injuries also increased with the length of time uncomfortable positions had to be maintained. Atlas found that making ergonomic improvements to truck cab designs, control placement and operator actions, could significantly reduce the risk of musculoskeletal injuries across all driver populations.

Atlas President James Lansman told EHS Today, “Fortunately, as our historical data and work in transportation have shown, driver risk can be measurably reduced through simple, low-cost adjustments to the cab and the drivers’ routines. The data show that sound ergonomics can have a direct, significant impact on trucking companies’ financial performance — which executives may find particularly encouraging in this difficult economy.”

DJ Products ergonomically-designed material handling equipment provides the same benefits to businesses that utilize material handling equipment to move materials, equipment and products in the workplace. Our motorized carts and battery-powered cart movers are engineered to take the burden off workers’ bodies and allow materials and equipment to be transported and maneuvered without musculoskeletal strain or injury. DJ Products’ ergonomically-designed material handling equipment allows equipment to be adjusted to optimal height for use by workers of any size, age or physical ability, ensuring maximum production during every shift.
