Twin Trolley Electromagnetic and Hook Gantry Crane
The general gantry crane (hereinafter the crane) is one of the most widely used hoisting machines. It runs on ground rails supported by legs on both sides and handles intermittent and repetitive loading, unloading and transfer of materials and equipment in normal outdoor working environments with vertical lifting plus longitudinal and transverse travel. Load-handling devices can be hooks, grabs or electromagnetic chucks to suit a wide range of materials. Depending on requirements the legs can carry cantilevers on both sides or on one side, or no cantilevers. Duty classes A3–A8.

Advantages & features
- 01
The control console has a PLC module and HMI touchscreen with a WLK master controller: distinct feel, clear positions, zero-position self-return and locking.
- 02
The electromagnet picks up and releases by switching the current, with a response time of only 0.5–1 s; in steel handling it can complete 80–100 pick cycles per hour, greatly improving continuous operation.
- 03
Finite element analysis optimises the load distribution in the main girder, legs and end carriages for outstanding rigidity and deformation resistance.
