Key Elements to Seek in Material Handling Equipment

No matter what business or industry you are in, you need to move materials. Whether you’re dealing with raw materials, parts and supplies or a finished product, you need equipment that can move materials from point A to point B. When choosing material handling equipment, there are a number of key features to consider that will maximize your investment and the use you get from your equipment.

  • Flexibility. The more jobs a piece of equipment can perform, the more workers who can easily utilize it, the greater the number of environments in which it can operate, the more useful it is to you and the greater its value. DJ Products’ carts and movers are designed for maximum versatility. Ergonomic design ensures that workers of every size, age and physical ability can operate our equipment safely and without effort. DJ Products’ electric lift option and customized attachment eliminate the need to fabricate multiple attachments for each cart or piece of equipment.

Ergonomic Design Lowers Risk of Musculoskeletal Injury

Manual material handling (MMH) contributes to more than half a million musculoskeletal injuries a year in the U.S., said a 2007 report published by the California Department of Industrial Relations. A joint study by California OSHA and the National Institute for Occupational Safety and Health (NIOSH) found that “effective ergonomic interventions can lower the physical demands of MMH work tasks, thereby lowering the incidence and severity of the musculoskeletal injuries they cause. Their potential for reducing injury-related costs alone make ergonomic interventions a useful tool for improving a company’s productivity, product quality, and overall business competitiveness.”

Musculoskeletal injuries, primarily strains and sprains to the lower back, shoulders and upper limbs, “can result in protracted pain, disability, medical treatment, and financial stress for those afflicted with them,” warns the report. Such injuries carry a double whammy for employers who “often find themselves paying the bill, either directly or through workers’ compensation insurance, at the same time they must cope with the loss of the full capacity of their workers.”

The report recommends adopting ergonomic solutions that reduce the physical demands of MMH tasks, including:

  • Using simple transport devices like carts to move loads,
  • Eliminating lifting from the floor,
  • Using lift-assist devices like scissors lift tables, and
  • Analyzing and redesigning work stations and workflow.

Electric Carts Ease Strain of Push-Pull Tasks

Pushing and pulling are the two most required actions in industrial and business settings. Unfortunately, pushing and pulling can place extreme stress on a worker’s body, often resulting in back, groin and other musculoskeletal injuries. Injuries can cost an individual business thousands of dollars each year in medical, insurance, disability and lost man-hour costs. An ergonomically designed electric cart pusher and motorized cart puller eliminates the physical strain of manually pushing and pulling heavy carts and wheeled equipment. An investment in ergonomic equipment is a sound investment in the health and safety of your workforce that can save your business thousands of dollars in unnecessary medical and insurance costs.

In manufacturing and distribution settings, the most common solutions to material handling tasks are:

  • to place products, parts and equipment on pallets for handling or
  • to utilize racks, carts and casters to move materials.

Electric carts come in a variety of shapes, sizes and configurations to fit the demands of the task and the capabilities of your workforce. An ergonomically-designed cart mover reduces the amount of force that must be exerted by the operator to maneuver a load. Various cart and wheel configurations are available to meet the needs of any task.

  • Carts, racks or equipment with casters can be easily turned and maneuvered with a CartCaddy power tug that feature a 5th wheel turning method.
  • Carts, racks or equipment with 4 swiveling casters require a cart with back end control.
  • Specialized CartCaddies and an electric tug have been designed to handle carts or equipment that have straight wheels or are on a rail.

Managing a Multicultural Workforce

America’s workforce is becoming increasingly multicultural. At this year’s MHEDA convention, keynote speaker Steven Little predicted that changing demographics will redefine material handling workers and change the way we do business. As Baby Boomers retire and the U.S. workforce shrinks, industry will need to turn increasingly to foreign and immigrant workers. Within a decade, Little said, Spanish will be the primary language spoken in 20% of U.S. homes. Overcoming the language and cultural barriers presented by a multicultural workforce is expected to present a significant challenge for many industries, including material handling, warehousing and logistics operations.

As they have since the founding of America, immigrants bring with them a wealth of diverse languages, cultural traditions and customs. However, communication, productivity, and worker morale can suffer when differences are not addressed. This problem is already being experienced by businesses in the West and Southwest who employ Hispanic workers. Hispanics are one of the fastest-growing groups in the U.S. workforce. Unusually high injury rates and on-the-job deaths among foreign-born Hispanic workers prompted business owners to ask OSHA for help. In response OSHA is starting to offer classes on the social hierarchy of Latino and Asian cultures, both of which are more highly structured and rigid than American culture.

Accommodating the language, customs and social structure of foreign workers is necessary if immigrant workers are to be effectively integrated into the U.S. workforce. Material handling, logistics and warehousing firms that are proactive in accommodating language and cultural differences into their workplace routine will be able to profit from the increasing diversity of America’s workforce.

Ergonomic Wheel Design Improves Productivity

In our last post we talked about the importance of wheel design in reducing friction. But why is that important? The answer is that any design element that decreases the force that must be exerted by the operator to manipulate a piece of equipment increases efficiency and decreases the risk of potential injury. The result is greater productivity. This is the goal of ergonomic design both in the design of equipment and the environment in which it will be used.

When a wheeled piece of equipment is used, the operator must first overcome inertia and friction. The initial force necessary to start an object in motion is far greater than the sustained force necessary to keep it moving. Once in motion, optimum sustained, or rolling, force is achieved when a steady, constant velocity is achieved. Any need to decrease or increase velocity requires increased force to combat inertia. This is particularly noticeable during turning and maneuvering when significant force must be applied to change direction. Stopping a piece of wheeled equipment requires the same high level of force as starting it. As when accelerating, the operator must overcome high levels of inertia and friction to decelerate.

The four physical elements required to move a piece of wheeled equipment — starting, rolling, turning and stopping — can place tremendous stress on the operator’s musculoskeletal system. If performing these tasks manually, workers frequently overexert and strain muscles while applying the necessary force to start or stop a piece of equipment. Turning and positioning equipment can cause operators to assume asymmetric body postures during exertion which can cause musculoskeletal injury.

Ergonomically designed carts and tugs seek to achieve the optimal wheel size, type, placement and composition to decrease the force an operator must exert to move a piece of equipment.

Pushing vs Pulling Manual Carts

Pushing and pulling are the two most frequent actions workers execute in the course of doing their jobs. So in maneuvering manual carts, which is easier for the worker and creates less risk of injury — pushing or pulling?

Experts say pushing is preferable to pulling for a number of reasons. Research has demonstrated that people are able to exert higher push forces than pull forces. Given that horizontal push force, not the weight of the load or equipment, is the most significant factor in determining the effort required to move a load, that’s a significant consideration in selecting equipment.

Think of what happens to the body when you push something. Your entire body is used to create push force. In pushing an object, your body is more centered which allows you to concentrate force. Limbs are generally held closer to the body, limiting the possibility of extension injuries.

Pulling on the other hand, creates tremendous stress on individual body parts. When you pull an object and you are facing the direction of travel, one arm is stretched behind your body. This places the shoulder and back in awkward postures, increasing the potential for painful injury through overextension or awkward twisting. If you use two hands to pull an object you must have your back to the direction of travel. Walking backwards without a clear view of your path is an invitation to an accident. On an incline momentum can increase unexpectedly and the cart can careen into the worker or “run over” his feet.

There are times when pulling is the only way to maneuver a manual cart into the proper position, but at all other times pulling should be avoided. Pushing is the safer, more ergonomic way to move a manual cart.

Handhold Design Can Improve Worker Efficiency

Most carts have handholds of one sort or another. Handles are such an ordinary part of everyday equipment that it’s easy to ignore their importance in efficient equipment use. But handholds are the link between the operator and the load. Handholds cue the operator on how much force to exert and where to apply it most effectively to move the load. Handhold placement and design on carts can increase or decrease the ease and efficiency with which a worker moves a load.

In evaluating the usefulness of a cart, consider these important elements of handhold design:

  • Handhold Height. Handhold height defines the operator’s posture, and posture determines the amount of force a person is able to generate when moving a cart. Given the difference in human size, no single handhold height will be optimal for all workers. Handholds that cause operators to bend or stoop can lead to musculoskeletal injuries. When handholds are located at the proper height for an individual’s body, he is able to exert maximum force without straining his body. An adjustable handhold system will accommodate workers of various sizes. Other solutions include a continuous vertical handhold system that can be grasped at any point along its length or a series of handholds at varying heights.
  • Handhold Width. Handholds should allow the operator to grip the cart near its outer edge to provide maximum leverage for turning and positioning. However it’s important that hands, fingers or arms not protrude beyond the side of the cart to prevent crushing injuries should the cart come in contact with a wall or other equipment.
  • Handhold Type. The type of handhold can dramatically affect the amount of force an operator is able to exert when maneuvering a cart. Poor coupling, the contact between hands and equipment, can decrease the force an operator can exert by 65%. Handhold shape should not concentrate pressure on any specific area of the hand. There should be no sharp edges or pronounced ridges. Both the palm of the hand and the fingers should be able to contact the handhold which should be wide enough to accommodate the entire hand.
    Note: Pulling tasks require a handhold that can be gripped with the fingers wrapping around the handle. Pushing tasks need only a good surface that provides stable hand/equipment coupling.

Ergonomics Can Significantly Decrease Worker Injuries

Material handlers and laborers suffer more injuries and illnesses than construction workers, truck drivers or, indeed, any other category of workers, according to the U.S. Department of Labor. Material handlers and laborers miss more work days and therefore cost U.S. businesses more money in lost man-hours and higher insurance and healthcare costs than any other worker class.

Numerous studies have proved that ergonomically-designed equipment and systems can significantly decrease worker injury. Many manual tasks necessary during the handling of materials require repetitive motions — pushing, pulling, bending, lifting and carrying — that place undue strain on the human body. These actions can result in sprains, strains, back pain and other musculoskeletal injuries. Back pain is by far the most commonly reported workplace injury in the material handling industry. Treatment is generally lengthy and expensive, gobbling up the lion’s share of healthcare and workers’ compensation costs.

The implementation of an ergonomics program can significantly reduce injuries and their associated costs while improving productivity and worker morale. The Material Handling Industry of America (MHIA) has published a 68-page booklet of tips for improving ergonomics in the material handling industry. Click this link to download MHIA’s free Ergonomic Guidelines for Manual Material Handling. For more information on ergonomically-designed electric and motorized carts, pushers and tuggers, visit the DJ Products website.

Next time we’ll share some of MHIA’s best tips for improving ergonomics in the material handling industry and reducing worker injury and its associated costs.

Electric Tuggers Improve Ergonomics in Material Handling

Improving the ergonomics of material handling decreases worker injuries, improves workplace efficiency and leads to a healthier bottom line. Medical costs, insurance premiums, workers’ compensation payments and lost man-hours soar when ergonomics are ignored. Material handling is one of the most injury-intensive industries, according to the U.S. Department of Labor. Every effort you make to fit the demands of work tasks to the capabilities of your workers (i.e., ergonomics) will decrease costs and ultimately improve profit margins.Material handling requires many actions that can result in serious and expensive musculoskeletal injuries. Repetitive motions, awkward postures and the application of force as workers lift, push, pull, carry and handle materials create daily opportunities for injury. Attention to ergonomics in designing tasks, workspaces and equipment can dramatically decrease the physical demands and injury potential of many material handling activities.Carrying and lifting are the two actions that present the greatest potential for worker injury when handling materials. Today we’ll address tips for ergonomic carrying; on Friday, we’ll share tips for lifting ergonomically.Carrying tasks place stress on the back and shoulders and create contact pressure on the shoulders and hands. When repeatedly strained or overstressed, the effort and force needed to carry materials can cause injury. To decrease injuries caused by carrying, follow these suggestions:

  • Eliminate unnecessary carrying.
  • Minimize the distances materials must be carried and use electric tuggers to carry materials over longer distances.
  • Organize work tasks so that physical demands and work pace increase gradually as muscles warm up.
  • Rotate workers or alternate carrying with non-carrying tasks to prevent overstraining the body and give muscles a chance to rest between efforts.
  • Wear properly fitting gloves to improve grip stability.
  • Reduce load weights and test loads for stability and balance before carrying.
  • Slide, push or roll materials. These actions place less stress on the body than carrying.
  • Use conveyors, slides or chutes to move materials.
  • Use electric tuggers to transport heavy loads.

Is Absenteeism Hurting Your Bottom Line?

The nation’s 300 largest employers reported in a 2007 survey by research firm CCH Inc. that absenteeism costs their businesses more than a quarter million dollars annually in direct payroll costs. Add in lost revenue from lower productivity and unscheduled absences can have a significant negative impact on a business’ bottom line. In these recessionary times, absenteeism can make already slim profits disappear.

Only a third of all work absences are due to illness, said Susan Frear, director of education for the Dallas office of the Society for Human Resource Management. “The rest of the absences are related to having to be someplace else or they just don’t feel like coming in. So a lot has to do with the culture of the place.”

Changes in management style or corporate procedures can make a significant difference in absenteeism rates. “Take a hard look at the climate,” suggests Barb Ashbaugh, owner of Ashbaugh’s Trade Secret, a performance management company. Authoritarian managers “who make employees feel it’s their way or the highway” cause higher levels of absenteeism, Ashbaugh noted. Companies that count “occurrences” instead of individual days absent encourage employees to sneak in a couple of extra days off, warned Nancy Glube, an Atlanta human resources executive.

Retail giant J.C. Penney Co. is trying a new approach that shows promise for both large and small businesses. With 1,500 workers calling in “sick” and another 1,200 out on disability each day, Penney executives were concerned about the impact of growing absenteeism rates on the company’s profit margin. This fall they began project PowerLine. When an employee is absent for 3 days, the PowerLine team swings into action. They communicate with the employee to determine the nature of the absence and whether the employee qualifies for health insurance, workers’ compensation or short-term disability benefits. The team notifies store and department managers and insurance carriers and sends the employee the appropriate forms to complete. Daily absenteeism rates have dropped dramatically.

What has made the PowerLine program so successful in such a short time is the constant follow-up that continues until the employee returns to work. “I’ve found that when someone goes out on disability, that person undergoes a significant event in their life,” said Penney’s benefit manager Jim Cuva, “and if no one checks on them to see how they’re doing, they could stay out longer than necessary.” The PowerLine program is Penney’s way of “letting them know we care.”

Employees who know they’re valued work harder, are more productive and are absent less frequently. Making the effort to create a positive work environment can positively impact your bottom line. On Monday, we’ll talk about how implementing ergonomic practices in your workplace can improve worker morale, decrease worker injury and boost your bottom line.
