Tunnel Trestle Crane with Electric Trolley

Tunnel Trestle Crane with Electric Trolley Hydraulic Inverted Arch Trolley bridge formwork is one of the main components of the tunnel structure.Inverted Arch Trestle Trolley is the foundation of the tunnel structure. On the one hand, Electric Trestle Trolley is necessary to effectively transmit the formation pressure of the upper part of the tunnel to the underground through the tunnel side wall structure or the load on the road surface, and Arch Trestle Trolley also effectively resists the reaction force from the lower layer of the tunnel. In fact, Hydraulic Inverted Arch Trolley is a kind of foundation beam (slab) that can bear the permanent load of the ground and the temporary load of the road (dynamic load). For this reason, the stress state of the back arch is more complicated. Judging from the examples of traffic tunnel engineering diseases at home and abroad, due to the design and construction of the Inverted Arch Trestle Trolley structure, the tunnel stru…
