With strict regulations in place to protect worker’s exposure to hand-arm vibration (HAV), professional grounds maintenance equipment manufacturer Dennis, are continually striving to improve their machines in recognition of the need to counteract harmful vibration.
Vibration can damage blood vessels and nerves in the fingers, leading to a loss of feeling in the fingers and hands. It can cause the industrial disease ‘vibration white finger’ which, in extreme cases can make it too painful for workers to hold equipment.
These issues are close to the heart of managing director, Ian Howard. “We continually look at ways to improve the health and safety on all of our existing products. We have spent a considerable amount of time with external consultants, including universities and QuinetiQ, a company who provide research, technical advice, technology solutions and services to customers in core markets of defence and security.
“Solving vibration is a complex science, and these findings give us a better understanding of the issues and solutions concerned. It is essential to keep the machine user friendly, without compromising performance. Our handlebars are now designed with low vibration as a key focus” comments Ian. Keeping true to their ‘customer driven’ design policy, Dennis have further enhanced operator comfort with the introduction of Honda’s latest low noise, low vibration engine type, Q9.
Dennis are currently conducting a number of ongoing research and development initiatives into health and safety, and projects planned throughout 2010 include further work on engine vibration and noise reduction.
