Grab and Hook Combination Gantry Crane
The grab and hook combination gantry crane is a multi-purpose machine that switches between grab and hook with a quick-change device, suited to mixed handling of bulk and general cargo. A dedicated quick-coupling mechanism allows fast changeover between the grab (for bulk such as coal and ore) and the hook (for general cargo). The grab grips material through coordinated closing and holding ropes, while hook mode is used for conventional lifting.

Advantages & features
- 01
Advanced variable-frequency control keeps the overall failure rate low, travel speeds high and handling efficiency high.
- 02
Grab opening and closing is hydraulic or mechanical, with fast response (a single cycle within 3–5 s); combined with the crane's hoisting and travel motions it supports high-frequency continuous operation.
- 03
Wheels are made by a combined forging and rolling process, drum-shaped gear couplings and modular design allow core components to be replaced quickly.
