meeting the challenge minimizing injuries while increasing productivity today s modern automated manufacturing climate is exacting a high price for its productivity and we re all paying it in the past decade performance of some repetitive tasks at work has been linked with certain health problems cumulative trauma disorders ctds most often affecting the hand arm wrist and shoulder may result from repeated gripping twisting reaching and bending over weeks months and years at coopertools we re using advanced ergonomics to refine our drill grinder and fastening system design our goal to achieve maximum productivity while minimizing workers health and safety risks work-related injuries cost all of us businesses lose good productive employees to early retirement employees endure pain and loss of wages while consumers end up paying for medical treatment and business losses through higher prices for products the bottom line improving worker comfort safety and satisfaction are good for e

improving job ergonomics and worker safety is your responsibility too bringing ergonomic advancements into power tool design can go a long way toward improving worker productivity and safety but they won t do it alone in addition to the choice of tools both the organization of the work to be done and the work habits of tool users deserve in-depth consideration s devote time to training new workers and continue training existing workers with emphasis on work-health issues s expanding individuals tasks beyond a single function that is job enlargement can help relieve chronic repetition s cross-training and job rotation are other ways to avoid overly repetitive tasks and provide rest for sensitive muscle groups an optional exhaust overhose is available for dotco tools as shown here on a 12r91 series precision turbine this allows the exhaust to be routed away from the operator for improved comfort optional overhose directs exhaust noise away from operator single hand operation for eas

adding new meaning to user friendly in efforts to improve power tool user comfort levels some operational factors deserve special attention noise process airflow and vibration-induced noise from pneumatic tools should be within osha and iso standards double chamber pulse unit large drive locating diameters limit extension run-out to reduce vibration top air inlet to allow air drops from above enabling proper workstation setup dust an avoidable byproduct of grinding and other operations fine dust particles should be collected and trapped by a vacuum source near the workstation before they are absorbed into workers lungs torque reaction industry consensus is that 100 inchpounds is the maximum torque that should be delivered use of high pressure low pressure pulse low-force start trigger mechanism handle coating for operator comfort acceleration via tool software coded with hard algorithms operator detection of speed shifts is avoided the result is less fatigue to the operator and

how to build high-output tools with a high level of comfort vibration-reducing dampening materials should surround motor housings thermally-isolated composite handles reduce tool weight and the effects of cold temperatures different handle sizes are provided to accommodate physiological and gender differences among users special mufflers can reduce sound levels to accepted standards without compromising tool power and performance handle design should direct cold air exhaust and possible oil mist away from workers hands torque reducers help assure a captive grip ideal for comfort and control yet resist in-hand tool movement under load vibration is minimized through the use of specially designed comfort grips which isolate the operators hand from the tool in some cases composite housings are also used impact and stain-resistant plastic composite handles provide shock absorbency and thermal protection lever triggers located in tool grips can simplify long-cycle operation and high-force
