Overhead Cranes
Double Beam Overhead Cranes
The overhead cranes are composed of two main beams supported at the extremities by the end carriages that execute the translation movement of the 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 overhead 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 Overhead Cranes
The overhead cranes are composed by a main beam supported at the extremities by the end carriages that execute the translation movement of the crane. The hoist; lifting and direction movement; works under the main beam. It should also be noted that more than one hoist can work on the same overhead crane, working simultaneously with the main hoist, or performing an auxiliary function.
Capacity | Max. Span (meters) |
|---|---|
To 5 Ton | 30 |
5 to 12,5 Ton | 26 |
