Stage Produktverantwortung

Product responsibility

Human vibration refers to any kind of vibration a forklift driver experiences during their working day. To prevent any detrimental impact to the operators’ health, this vibration is not permitted to exceed a specified level. Our approach is to keep this form of stress to a minimum. We will come to your premises and measure the vibration stress levels on-site.

What operators of industrial trucks must note

Human vibration can lead to muscular and skeletal damage and circulation problems. The operator may also feel uncomfortable, productivity may be affected, and employee health and safety may be at risk.

Case examples of optimum vibration reduction

This section describes how we set about significantly reducing human vibration.

Glossary

Technical terms about human vibrations

Vibration emissions:

Machine-generated vibrations act on the user’s organism. The vibration emission value specified by the truck or machine manufacturer in the operating manual provides a standardised value for the level of vibration. 

This figure can be used to draw preliminary comparisons between different trucks, but not to determine compliance with the requirements of 2002/44/EC. While manufacturers can optimise their trucks for vibration affecting the driver, no maximum exposure can be given, because of the many individual factors involved.

Daily exposure, A(8):

This is the actual vibration value for a worker over a period of eight hours. The accelerations acting on the operator, indicated in m/s², characterise the level of exposure to whole-body vibration over a one-day period (one shift).

Exposure action value:

If the daily vibration magnitude A(8) (for whole-body vibration) exceeds 0.5 m/s², employee health surveillance is required, along with a programme for the minimisation of whole-body vibration.

Exposure limit value:

The exposure limit value is defined as a daily vibration magnitude A(8) for whole-body vibration of 1.15 m/s² (figure for Germany) in the longitudinal and lateral axes, or 0.8 m/s² in the height axis. This value is not to be exceeded, and triggers immediate countermeasures. No employee is to be exposed to levels above this value.
