Remote Control Clamshell Grab Bucket
Remote Control Clamshell Grab Bucket is an advanced crane grab that integrates wireless remote control technology with a classic clamshell structure, enabling the grab to open and discharge at any position in mid-air. Designed for single-hook cranes, it operates without external power cables by using an internal remote control system (battery-powered or mechanical release), allowing precise and efficient handling of bulk materials such as coal, sand, gravel, ore fines, and grain in ports, vessels, and stockyards.
