The cranes are intended for building sites and restoration jobs where accessibility problems, such as historical city centres, prohibit installing traditional cranes. The portal base, width between 2.4m and 3.8m, and up to 4.5m high, allows vehicles and people to walk underneath the crane.
The GHS351, the GHS401, the GHS451 and the GHS501 have jib lengths of 35m, 40m, 45m and 50m, and have a capacity of 1t at jib-end, and 2t maximum. The two smaller models have a hook height of 36m and the larger two 41m.
The cranes have inverters with three speeds on all movements and have structural components with no more than 6m long.
Reinforce concrete support slabs help reduce the bearing pressure on the ground.
