Main purpose:
The grab-type trolley is designed for travelling of the load-handling device (grab) along the crane bridge and ensures lifting, transporting and unloading operations of bulk materials within the crane working area. The trolley design ensures efficient operation of the rope and sheave system and stability of the mechanisms during operation.

For proper and even winding of the rope on the reels, rope guides are used to prevent incorrect winding or rope jumping between layers.

The trolley is also equipped with lateral guide rollers, which stabilise its position relative to the I-beam. They prevent lateral displacement and skewing during travel, ensuring reliable operation of the travelling mechanism.
