Apron conveyors transport materials whose consistency or size would damage conventional conveyor belts. The transported loads fluctuate widely and reach very high maximum loads. These reduce when the material is transported to the subsequent machine and subsequently rise when the next load is received.

This means that the system's drive technology has to deal with demanding requirements characterized by extreme torque fluctuations and large shocks. The components used also have to be reliable and quickly available. This reduces idling times to a minimum and increases the operating life.

Industrial gear units for difficult operating conditions

For apron conveyors, the industrial gear units are generally positioned at the end of every conveyor belt where they drive the two shaft ends. A frequency inverter typically operates as a controller.

The preferred drive technology for this application includes a planetary gear unit with a hollow shaft and shrink disk. This also includes a long torque bracket on the output side of the planetary gear unit's housing flange. All the system components must be able to deal with the difficult operating conditions.
