Linde counterweight stacker
Standard Euro pallets and fork-lift trucks are the equipment of choice for the /transport of larger and heavier materials. Bulky goods in particular often restrict the driver's view through the load, which may result in longer distances having to be travelled in reverse. This leads to postures of the cervical spine and trunk that are uncomfortable and harmful to health.
Larger trucks in the Linde range have the option of being fitted with driver's operating platforms that can be rotated through up to 180° and thus enable the stress during driving in reverse to be reduced considerably. The improved visibility also improves safety.

The Technical Report ISO/TR 22100-3 describes how ergonomic principles can be applied during the risk reduction process according to ISO 12100 and how ergonomics standards can be applied to machinery. It helps designers take decisions with respect to ergonomics during the machine design process and can also be used when no relevant type C standards are available.
When a forklift is used to transport bulky goods, the driver's forward visibility is often limited by the load. As a result, it may be necessary to travel longer distances in reverse. This leads to uncomfortable static body postures that are harmful to health, with strong twisting of the cervical spine and the trunk (see also EN 1005-4).

Linde's driver's rotating control stations can be fitted to larger models of forklift. By releasing the locking lever on the seat, the driver can swivel the entire control panel, including the seat, pedals, steering wheel and other controls, 90° to the side (see also EN ISO 21281:2005, Section 4; EN ISO 3691-1:2012, Section 4.7.4). This permits reversing without extreme twisting of the driver's entire body, since the driver need only turn his or her head in order to view the path to be travelled.
