500T Double Truss Bridge Girder Crane Electric Steel Structure 20m - 50m Span

500T Electric Steel Structure Highway Double Girder Beam Launcher Crane

Product Description

Double Girder Beam Launcher Crane is used to place concrete bridge and pier segments for elevated roadways and bridges by spanning the distance between a finished road segment and the next roadway pier or column. While spanning this distance, the launching gantry picks up each bridge segment and suspends the segments from beneath the overhead truss moving the segments into place.

Product Characteristics

Double Girder Beam Launcher Crane is a gantry crane specially designed for bridge construction. Beam elevators are mainly composed of assembled main beams, outriggers, bridge cranes, etc. The components are connected by pins and high-strength bolts for easy disassembly and transportation. Compared with ordinary gantry cranes, it is easy to install and economical and practical. Suitable for the construction of constantly flowing highway bridges.
There are many components in the beam crane, such as the main structure and power system, and each component has its own function. In addition, the main beam of the beam hoist still has two modes, one is a single beam and the other is a double beam. When we operate a beam crane, we must choose the appropriate method according to our needs.
According to requirements, the main beam has single beam and double beam modes, and the main beam structure usually adopts the box beam mode with good torsion resistance. The main structure of the beam crane is a key part of the security of the beam crane. The strength, stiffness and stability of the main structure must meet the requirements of the code. Designers and manufacturers have optimized the main structure to reduce costs. Whether the situation is different, whether the load analysis, calculation equipment and calculation methods are correct, are the main design factors for determining the use value of beam machine security.
The rigidity of a beam crane requires that the amount of downward deflection of the middle span is less than 1/700 of the span under static load. Stability includes unilateral stability and overall stability; Unilateral stability refers to the flexural strength of box-shaped steel plates, which is ensured by adding vertical and horizontal ribs.
The overall stability includes the stability of the main beam and outriggers, and there is still wind stability. Beam cranes must be taught at the specified wind level. It is strictly forbidden to use when the wind is too strong.
