Grab and hook dual-purpose gantry crane is a multi-functional lifting equipment that realizes switching between grab and hook through a quick-change device, suitable for mixed loading and unloading scenarios of bulk materials and general cargo. Equipped with a dedicated quick connection mechanism, it can flexibly switch between grab (for handling bulk materials such as coal and ore) and hook (for lifting general cargo). The grab controls material grabbing through coordinated operation of opening/closing rope and supporting rope, while the hook mode is used for conventional lifting operations.
Type Test Specification: MHZE
Type Test Product Name: Electric Hoist Gantry Crane
Advantages/Core Functions:
Low overall failure rate, fast operating speed and high lifting efficiency.
The opening and closing action of the grab is realized by hydraulic or mechanical transmission, with fast response speed (single opening/closing time can be controlled within 3-5 seconds). Combined with the lifting and traveling mechanisms of the crane, it can achieve high-frequency continuous operations.
Adopts wheel forging and rolling composite process, crowned tooth coupling, modular design, and core components can be quickly replaced.
