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.

EHS Today online, a magazine for environment, health and safety leaders, published an interesting April 24, 2009 article comparing truck driver demographics to risk factors for musculoskeletal injuries. As in any job that requires long hours in a single position, long distance truck drivers are at increased risk for musculoskeletal injury on the job. According to a recent study by Atlas Ergonomics, truck drivers lose more workdays per musculoskeletal injury incident than any other group of workers. Fortunately, risk factors can be predicted and workers protected.

The three-year study of 28,301 commercial truck drivers was conducted from 2005 to 2008. Drivers were primarily engaged in driving and delivering loads with less than 10% of drivers’ activities involving the unloading of freight. A direct relationship was found between injury risk and the physical characteristics of the both the worker and truck cab. The driver population studied was predominately men of slightly taller stature and weight than average.

• The study found that height caused the greatest discomfort while driving. Taller drivers were forced to contort their bodies to fit into cab spaces, while shorter drivers had to stretch to reach controls.
• Weight, particularly obesity, significantly increased injury risk factors. Obesity increased driving discomfort to severe levels and, in many cases, resulted in sleep apnea and other sleep disorders that impaired alertness.
• Driver age was spread across all age groups from young, new drivers to near retirees. Discomfort increased with age and length of service, three to five years of seniority producing greater risk. Injuries to workers 65 and older resulted in longer work absences after injury.
• While women drivers constituted just 8% of the study group, their smaller stature resulted “in elevated levels of discomfort across all body parts,” according to study results. Muscular strength may also have played a role but was not specifically studied.

While operating material handling equipment is significantly different from long-haul trucking, there are important similarities when workers are forced to maintain steady postures for long periods of time or repeatedly perform the same actions over a shift. The findings of the Atlas Ergonomics study has instructive lessons for material handling equipment purchasers who want to decrease the risk of worker injury in their workplace. We’ll talk about that next time.

The economy is driving people in search of inexpensive travel and vacation options and, in many cases, inexpensive housing. RVs seem to fit the bill. Record-setting attendance at RV shows has led to strong first quarter sales in the recreational vehicle industry. With young adults aged 18 to 34 comprising the fastest growing segment of RV owners, industry watchers expect RV sales to remain strong well into the future. RVs are the perfect vehicle for active folks who appreciate the outdoors and are looking for an easy, eco-friendly way to travel. The ability to take off for a quick weekend or mini-vacation is as appealing to young adults as it is to busy families and retirees.

Increasing RV sales are creating a ready market for DJ Products’ popular TrailerCaddy trailer mover. More RV buyers mean more RVs moving across sales lots and in and out of showrooms. DJ Products’ trailer mover is the perfect solution for manufacturers, dealer lots, trade shows and service centers. Our versatile TrailerCaddy is designed to push and pull trailers that require lifting on one end before maneuvering. DJ Products’ ergonomic design provides powerful pulling strength while protecting workers’ health and insuring their safety. Our ergonomically-designed material handling equipment is built to prevent the physical strain that occurs when workers are forced to muscle around large trailered equipment. Ergonomic design ensures that the equipment, not the worker, takes the strain of moving and maneuvering heavy equipment.

DJ Products’ TrailerCaddy makes easy work of pushing and pulling all kinds of recreational vehicles, including RVs, campers, equipment trailers and boats. Our electric-powered trailer mover is the perfect solution for moving recreational vehicles down an assembly line, around a manufacturing plant, across sales lots and showrooms and into trade show spaces. The compact design of DJ Products’ powered TrailerCaddy allows superior, precise movements, making quick work of maneuvering large recreational vehicles through crowded spaces and into display areas without fear of damaging surrounding vehicles. As RV sales continue to increase, you can expect to see more manufacturers and dealers turning to DJ Products’ handy TrailerCaddies to move recreational vehicles.
