The electric hoist semi-gantry crane is a small and medium-sized hoisting equipment that runs on rails. It mainly consists of a mast (main beam, outriggers, lower beams, etc.), a hoisting mechanism, an operating mechanism, and an electric control part. The electric hoist is used as a hoist. The lifting mechanism runs along the lower flange of the I-beam of the main beam when working. There are outriggers on one side of the mast, which runs along the ground track, and the other side has no outriggers, and runs along the track on the upper part of the plant. The rest of the structure and configuration are the same as the MH electric hoist gantry crane.

The side-mounted electric hoist gantry crane is mainly composed of mast (main beam, outrigger, lower beam, etc.), hoisting mechanism, operating mechanism and electronic control part. The electric hoist is used as the hoisting mechanism. The lower flange of the shaped steel runs. The outriggers and the lower crossbeam form an L shape, with large lifting space and strong spanning ability, which is convenient for transferring objects from the span to under the cantilever. It is suitable for general loading, unloading and hoisting work in outdoor places such as factories, mines, cargo yards and warehouses within the range of small and medium lifting capacities.

There are three operation modes: ground handle, wireless remote control and driver's cab.

There are two forms of power supply: cable reel and high-altitude sliding line.

Electric hoist gantry crane is a small and medium-sized lifting equipment that runs on rails. It is mainly composed of mast (main beam, outrigger, lower beam, etc.), hoisting mechanism, operating mechanism and electronic control part. Electric hoist is used as lifting equipment. The mechanism runs along the lower flange of the I-beam of the main beam when working. The gantry structure is divided into two types: box-shaped and truss. The box-shaped technology is good and easy to manufacture; the truss has light weight and strong wind resistance. The whole machine has the characteristics of light weight, simple structure, convenient installation and maintenance, etc. It is suitable for general loading, unloading and lifting work in outdoor places such as factories, mines, freight yards and warehouses within the range of small and medium lifting weights. It is prohibited to be flammable, explosive and corrosive. Work in a gaseous environment.

There are three operation modes: ground handle, wireless remote control and driver's cab.

There are two forms of power supply: cable reel and high-altitude sliding line.

This crane is specially designed for loading, unloading and stacking 20, 40 and 45-foot international standard containers in railway freight yards. This machine is equipped with a telescopic container spreader for lifting containers of different specifications. The opening and closing movement and expansion of the spreader are operated by the driver in the control room. At the same time, in order to adapt to different container stacking directions and container trailer walking directions, the container spreader can be designed with a rotating mechanism that can rotate the container at will to improve the efficiency of loading and unloading.

The new type of bridge crane is based on the introduction and digestion of foreign advanced technology, guided by modular design theory, and modern computer technology as a means, introduced optimized design and reliability design methods, and adopted imported configurations, new materials, and new The finished process is a new type crane with light weight, generalization, energy saving and environmental protection, and high technical content.

Hook bridge cranes are currently widely used hoisting machinery, which are mainly composed of box bridges, crane trolleys, cart operating mechanisms and electrical control systems. The retrieval device is a hook.
