Reach trucks are generally used for stacking of and retrieval from shelves and for the transport of goods within warehouses. They have forks that extend forwards and a driver's seat perpendicular to the direction of travel. The same conditions are therefore assured for forward and reverse travel in combination with a minimum space requirement. In addition, the reach trucks in the Toyota Material Handling Reflex R/E series are specially designed for stacking of and retrieval from high-level racks.

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 stackers with the driver's cab located at ground level are used for stacking of and retrieval from high-level racks, the operator must look upwards for long periods in order to monitor the operation. At increasing view heights and longer durations, this static head posture quickly becomes unpleasant, and may be harmful to health when exposure is sustained.
A tilting driver's cab assists in reducing the necessary angle of head inclination. Such a cab inclines to the rear as a function of the lift height. This results in the driver's body also being inclined to the rear and the required neck angle being reduced.
