Semi-gantry cranes can be divided into single-girder and double-girder types, which can be customized according to different lifting capacities, spans, lifting heights, working environments and control methods. Semi-gantry cranes can save space and cost, use the existing plant structure, expand the working area, and improve production efficiency. Semi-gantry cranes are suitable for various indoor and outdoor occasions, such as steel warehouses, precast yards, construction sites, ports, railway stations, power plants, etc.
Advantages of mobile semi-gantry cranes:
● It can move freely on the ground without tracks, and can also use the side support of the factory building or trestle to carry out operations, with strong adaptability.
● Covering more working areas, no need to change the plant structure, and the plant is more beautiful.
● Simple structure, flexible operation, safety and reliability, convenient maintenance, large lifting weight, low headroom, small wheel pressure, and stable operation.
