RAM4151 Revolver® for Bridge Crane


The Award Winning RAM Model 4151 ‘Revolver’ for handling of bulk materials for a Bridge Crane is designed in accordance with DIN 15018.

Manufactured from high quality steel and components as the conventional RAM Spreaders, the ‘Revolver’ provides robust and reliable operations in demanding conventional container terminal and bulk terminal environments.

The RAM ‘Revolver’ can be designed to interface with new or existing Bridge Cranes and electrical communication systems.

The ‘Revolver’ is electro-hydraulically operated with all functions of the spreader controlled via remote control.
