7.7 Wheel drive
Wheel drives are used in non-continuous conveyors. The drives are on the vehicle and therefore on
the non-stationary part. Compared to continuous conveyors, non-continuous conveyors have a
greater flexibility, but also higher costs for the individual vehicle. Therefore they are usually used for
cases where the transport volume and the use of the conveyor section is lower than for continuous
conveyors.
There are railway vehicles and non-railway vehicles. For railway vehicles the effort for tracking is
lower, however, they are not as flexible with regard to the routing . Since many automated internal
transport tasks have a defined travel way, they are frequently found in automated operation. For
non-automated internal transport the manually operated fork lift still is the most frequently used
means of transport in the field of industrial trucks.
Wheel drives in non-continuous conveyors can be found in the following applications:
• In rail vehicles (e. g. transfer carriages)
• In monorail overhead conveyors (MOC)
• In travelling and gantry cranes
• In storage and retrieval units (SRU)
• In automated guided vehicle systems (AGV).

Note!
The calculation only applies to travelling drives which are solely actuated by means of
wheels (no rope or rack and pinion).
Applications with toothed belts can be found in connection with the belt models.
