The single girder semi-gantry crane is a versatile light-to-medium duty lifting solution suitable for indoor workshop and outdoor yard operations. Its supporting leg height can be flexibly adjusted according to actual on-site construction and engineering demands. Adopting an offset rail box-type main girder structure, the equipment features simple overall layout, light self-weight, convenient installation and excellent wind resistance.
Compared with double girder gantry cranes, this single girder model is designed for small and medium load & span ranges, with standard lifting capacity up to 50 tons and maximum span of 35 meters. It matches CD1 and MD1 electric hoists, and supports dual operation modes: ground pendant control and wireless remote control to realize flexible on-site handling.
Safety Protection Configuration
Equipped with overload limiter to avoid overloaded operation and protect equipment security.
Fitted with high-toughness polyurethane buffers with superior impact resistance and long service life.
Installed travelling limit switches to restrict travelling stroke and eliminate collision hazards.
Built-in voltage loss protection and phase failure protection to guarantee stable power supply operation.
Configured emergency stop system for immediate power cut under abnormal working conditions.
Equipped with lifting height limiter to prevent over-winding and standardize hoisting actions.
