(1). Structure of segmental assembly bridge construction crane
The bridge construction crane is mainly made up of main girder, launching nose, front support, rear support leg, auxiliary front support, auxiliary rear support, lifting trolley, 10t overhead crane and transverse luffing mechanism.
(2). Advantages:
1. Easy operation, safe and reliable
2. Main girder of the bridge construction crane is of superposition box girder structure, featuring high stiffness and low deflection
3. Reasonable design, symmetrical design principle is fit for the main structure.
4. The bridge construction crane can execute a two-way construction of bridge and can have a better adaptability: feeding girders at bottom and rear part of the bridge.
Using HZP140 segmental assembly bridge construction crane will save a lot of manpower, material resources and time, shorten construction period, reduce construction cost, greatly improve bridge construction efficiency and speed, thus create economical benefit for the company.
