Winch Gantry Auxiliary Lifting capacity (AUX SWL): 50 kN (at hook)
Auxiliary Lifting speed: 0,6 m/min
Auxiliary Lifting stroke: Approx 22 m (approx 12m under WG top of rail)
Auxiliary Lifting type: Chain hoist, installed on Winch Gantry on delicate monorail beam
Auxiliary hoist class: A2 for structure/1 Am (M4) for mechanisms according to FEM std
Auxiliary Hoist traversing speed (transversely to LG along monorail beam):
- 4,0 m/min (low speed)
- 24,0 m/min (nominal speed)
Truss traveling speed (on a maximum slope): 0,25 m/min ÷ 2,5 m/min
Max weight of the winch gantry (to be optimized): 55 tons (including hook block)
