100T Trussed Type Bridge Launcher Equipment Beam Erection Crane

 

Product Description

 

100T Trussed Type Bridge Launcher Equipment Beam Erection Crane is a device that puts the prefabricated beam on the prefabricated pier. 100T Trussed Type Bridge Launcher Equipment Beam Erection Crane belongs to the crane category, because its main function is to lift the beam piece, and then transport it to the position and then lower it. But it is very different from cranes in general. The requirements are harsh, and there is walking on the beam, or it is called vertical displacement. 100T Trussed Type Bridge Launcher Equipment Beam Erection Cranes are divided into several types such as highway bridges, conventional railway bridges, passenger railway bridges and so on.

 

 

 

Classification of Bridge Launcher Equipment

 

100T Trussed Type Bridge Launcher Equipment Beam Erection Crane that runs on highways and railway tracks and is used to erect small span beams across the entire span. Because of its high erection efficiency, in the standard design of Chinese railway bridges, more consideration is given to using it as a design principle. Its body is huge and exceeds the limits of railway transportation. It must be disassembled and transported. After reaching the construction site, it can be assembled and used. There are three types of 100T Trussed Type Bridge Launcher Equipment Beam Erection Cranes in China, which are mostly used to erection reinforced or prestressed concrete beams in pieces.

 

Single Beam Bridge Launcher Equipment Beam Erection Crane

 

One of the Trussed Type Bridge Launcher Equipment Beam Erection Cranes, whose boom is a box beam, cantilevered forward, and at the front end there is a foldable column (composed of left and right legs). The machine can enter the bridge position by itself under no-load condition, and then straighten the front pillar and support it on the front pier. When the beam piece (or whole beam) is moved along the boom, the boom is close to the simply supported beam state. When the bridge is erected, the machine can be driven into the bridge position under no-load conditions. The beam must first be transferred from the railway flatbed to the special beam carrier using a special gantry crane, and then the beam carrier and the bridge crane must be transferred. End-to-position, use two crane beam trolleys traveling on the crane arm of the bridge crane to lift the beam sheet, and move along the crane arm to reach the bridge drop beam. In order to adapt to the curved bridge, the crane of the machine can make a small amount of swing in the horizontal plane. The method of positioning the beams is the same as that used for double cantilever bridge cranes (moving beams or lanes). The advantages of this machine are: cancel the balance weight, no longer need to push the locomotive, no need to bridge the fork to feed the beam, increase the degree of mechanization, and improve the safety performance. This is the case of the Victory Erecting Machine with a capacity of 130 tons.

 

Double Cantilever Bridge Launcher Equipment

 

One of the bridge construction machines, the Soviet Union used it earlier. When it was introduced in 1948, its front and rear arms were made of steel plate beams, with lifting weights of 45 tons and 80 tons. In the 1950s, the arms were changed to a framework, and the weight was developed to 130 tons.
This type of bridge erection machine cannot be used by itself. Its forearm is used to lift the beam, and the rear arm is lifted to balance the weight. The front and rear arms cannot swing in the horizontal plane. When erecting a bridge, it is often necessary to use a special 80-ton flat car to transport the beam piece under the hook of the forearm of the erecting machine (called "feed beam") before lifting; in order to facilitate the shunting operation, it is necessary to lay a fork at the bridge head. line. After the bridge crane lifts the beam, the axle weight increases, and the newly built embankment at the bridge head is relatively soft. Therefore, reinforcement measures must be taken on the driving section of the bridge crane crane beam, such as using heavy vehicles to press the road and insert sleepers.

 

Double Beam Bridge Launcher Equipment

 

Red flag bridge girder launcher cranes and prototype bridge girder launcher cranes belong to this category, and the lifting weight is also 130 tons. The boom is composed of two box beams on the left and right. The two beams penetrate the fuselage and extend forward and backward. At both ends there are folding columns consisting of two-legged poles. The central distance of the two beams of the red flag type is 3.4 meters, while that of the prototype is 4.8 meters. There are two trusses spanning two box beams, which can travel longitudinally along the boom. The hanging beam trolley is placed on the truss car and can drive along the truss transversely. The beam piece (or entire beam) to be framed can be sent directly under the rear arm of the bridge crane by a railway flatbed. After being lifted with a crane beam trolley, it is moved forward with a truss trolley, and then moved horizontally with a crane beam trolley. Bit. Both the front and rear ends of this type of bridge erecting machine can be used for hanging beams and falling beams; when changing the direction of the girder, there is no need to turn around; in order to adapt to the curved girder, the front and rear arms can be swung in the horizontal plane; Road, the beam can be put into place; "feed beam" does not require a bridgehead fork or a special beam carrier.
