Beam lifting machine is also called beam lifting gantry crane, which belongs to gantry crane in terms of crane type. The appearance looks similar to the gantry. The goods are lifted and moved back and forth in the middle. It mainly depends on the hoist to cooperate with the crane to walk. The whole work is repeated back and forth on the track. There are two types of beam lifting machines: box type and flower rack type. If the frequency of use is not very high, try to use flower trellis beam lifting machine. The main characteristics of the flower frame beam lifting machine are low cost, small weight of the whole machine, high economy, and convenient installation and transportation.
The bridge erecting machine lifts the beam from the ground to the beam carrier, and then the beam carrier transports the beam to the bottom of the bridge erecting machine. The two work together. Bridge erecting machines are also divided into several types. According to different walking modes, some bridge erecting machines walk by driving wheels, and some are guide beam structures. The bridge erecting machine is mainly used for erecting bridges, lifting concrete beams to the specified position and adjusting the direction. It is supported by four pillars. The main function of the bridge erecting machine in the process of highway bridge erecting is to transport the prefabricated beams to the piers.
The similarities between the beam lifting machine and the bridge erecting machine are that they both belong to lifting machinery and are used to carry bridges. Both can adopt flower rack structure, so the cost is relatively low and the transportation and installation are relatively convenient. The main beam structure of the two is the same, which can be single beam and double beam structure. The difference between the bridge erecting machine and the beam lifting machine is that the bridge erecting machine is used on the site of road and bridge laying, and the beam lifting machine is used in the bridge factory, and there is a beam carrier between the two. The division of work between bridge erecting machine and beam lifting machine is that the bridge erecting machine is responsible for laying the bridge on the pier, and the beam lifting machine is to lift the bridge to the beam carrier.
