Double-Girder Crane

The structure of double beam bridge crane

1. Bridge: composed of two main beams, two end beams, walking platform, guardrail and other parts. There are two types of structure: box type and truss.
2. Truck operating mechanism: composed of motor, brake, reducer, coupling, drive shaft, Angle bearing box, wheel and other components;
3. Lifting trolley: composed of frame, lifting mechanism and running mechanism of trolley;
4. The lifting mechanism is composed of motor, brake, drive shaft, coupling, reducer, drum, fixed pulley, wire rope and other components. Single and double gates;
5. Driver's cab: where the crane operator works. Equipped with control equipment (linkage or CAM controller), distribution protection box, signal device and lighting equipment. The crane can't start until the hatch is closed. This way, personal accidents can be avoided when someone is working or driving before entering the cab.

Double bridge crane has superior performance, compact structure, light weight, safety and reliability, high efficiency, and can meet various working conditions. It can reduce the overall investment of the factory, improve production efficiency, reduce maintenance costs, and save energy consumption in operation.

The models of double beam crane mainly include LH type, QD type and MG type.
LH type electric hoist double beam bridge crane
LH type electric hoist double beam bridge crane is a cost-effective double beam crane, the use of more. It is mainly composed of box-type bridge beam, large trolley running mechanism and electrical equipment, and the lifting mechanism is mainly fixed wire rope electric hoist. It is suitable for lifting and unloading operations in machining workshops, warehouses, storage yards and other places.

QD type universal bridge crane
The lifting mechanism of QD type general bridge crane is hoist type, which adopts the new conductive device of I-beam track cable, and runs stably and reliably. This type of double beam crane can be used with a variety of professional lifting equipment for lifting operations, and can be installed outdoors for loading, unloading and handling of outdoor heavy objects.

MG double beam gantry crane
MG double beam gantry crane has two forms: MG general gantry crane and MG engineering gantry crane. This kind of crane is suitable for storage yard, dock and other places that need large span and heavy load.

Application scenarios and performance parameters of different models

• LH type: suitable for lifting and unloading operations in machining workshops, warehouses, storage yards and other places. The maximum lifting weight can reach 50 tons, the maximum lifting height is 24 meters, and the span is 40 meters.
• QD type: suitable for loading, unloading and handling outdoor heavy objects, with stable and reliable operation performance.
• MG type: suitabcle for large span and heavy load places such as material yard and dock.

These types of double-beam cranes have a wide range of applications in industrial production and logistics, and the specific selection needs to be determined according to the working environment and use needs.
