Mobile Semi-Gantry Cranes
Double beam semi-gantry cranes
The semi-gantry cranes are composed of two main beams based over two legs. One end carriage is connected to the main beams and the other end carriage is connected to semi-gantry crane legs. The end carriages execute the translation movement of the semi-gantry crane. The hoist; lifting and direction movement; works on top of the two main beams. It should also be noted that more than one hoist can work on the same semi-gantry crane, working simultaneously with the main hoist or performing an auxiliary function.
Capacity | Max. Span (meters) |
|---|---|
To 40 Ton | 40 |
40 to 50 Ton | 33 |
50 to 100 Ton | 30 |
100 to 200 Ton | 25 |
Single beam semi-gantry cranes
The semi-gantry cranes are composed of two main beams based over two legs. One end carriage is connected to the main beams and the other end carriage is connected to semi-gantry crane legs. The end carriages execute the translation movement of the semi-gantry crane. The hoist; lifting and direction movement; works on top of the two main beams. It should also be noted that more than one hoist can work on the same semi-gantry crane, working simultaneously with the main hoist or performing an auxiliary function.
Capacity | Max. Span (meters) |
