Bridge Engineering Road Railway Various Tonnage Beam Launcher Rack Equipment

Product Description

Bridge Engineering Road Railway Various Tonnage Beam Launcher Rack Equipment applies to highway, railway bridges to the construction site of bridge construction, its main function is to mention prefabricated good beam slice and delivered on prefabricated good piers.it and general meaning cranes have very big different, high safety requirements.

Construction method

Bridge Engineering Road Railway Various Tonnage Beam Launcher Rack Equipments are devices that place precast beams on precast pier. Overhead cranes belong to the crane category because their main function is to lift the beam, then transport it to that location and then lower it. But it is very different from a crane in general. The required conditions are harsh and there is movement in the beam or longitudinally. Bridge construction machines are divided into highway bridges, traditional railway bridges and passenger railway bridges.

Classification

• Single-girder Beam Launcher Rack Equipment: The boom is a box girder, which is suspended forward and has a foldable column at the front end. It can be driven to the bridge position under no-load conditions, and then the front pillar is straightened and supported on the front pier. The advantages of mechanical equipment are obvious, the balance weight can be eliminated, no locomotive is needed, the degree of mechanization is improved, and the security performance is significantly improved.
• Double beam Beam Launcher Rack Equipment: The boom of the bridge crane is mainly composed of two left and right box beams, and the two beams pass through the fuselage and protrude forward and backward. There are folding columns at each end, consisting of two leg bars.
• Double cantilever Beam Launcher Rack Equipment: Unlike the other two types of cranes, the machine cannot propel itself and needs a locomotive to push it. The forearm suspension beam and the rear arm suspension are balanced, and neither of them can swing freely on a horizontal plane. Under normal circumstances, the rear axle weight of the bridge girder will increase. If the new embankment at the bridgehead is relatively soft, necessary reinforcement measures are recommended.

In the foundation pit construction, the common sheet pile engineering accident has the foundation pit collapse. The reason is that the bottom of the pit seeps, the top of the foundation pit is overloaded, the slope is not reinforced in place, and the slope of the foundation pit is not constructed as required.
