4CBM Radio Wireless Remote Control Clamshell Grab Bucket

OUCO certifications

The opening mechanism is operated hydraulically by remote control. The degree of load release can be controlled incrementally for a precision pour. • The deployment of hydraulics in the design saves cycle time, wear and tear on the crane, making it both faster to use and economically to own. • The power supply is integrated into the grab. This special feature makes the RRCG unique. There are no cables to maintain. • The RRCG is designed to close only on the ground or on cargo with cranes hoisting, not in the air. • No need for extra power supply from the vessel (typically for 4 Pcs of Electro hydraulic grab you would need 180 kW power supply). No need for a cable drum system, electric cable, electric panel, and pedals in the crane. • Can be fitted to most applications. • Need more wire distance (5m) in hoisting compare to electro-hydraulic grabs.
