300T Customized Expressway Bridge Truss Steel Structure Girder Beam Launcher
300T Customized Expressway Bridge Truss Steel Structure Girder Beam Launcher are lifting equipment that pass through materials in workshops, warehouses and yards. Because its ends are located on high concrete columns or metal supports, bridge cranes are the most widely used bridges.
The bridge extends longitudinally along the tracks on both sides of the elevated side, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and largest number of lifting equipment.
It usually consists of three parts: mechanical, electrical and metal structures. It is shaped like a single-span flat bridge with two ends supported on two parallel overhead rails. It can be roughly divided into lifting mechanism and trolley operating mechanism. And shopping cart run organization.
During the whole process, the lifting mechanism is used for vertical lifting and lifting; the trolley running mechanism is used for lateral load movement; the trolley walking mechanism is used for lifting the trolley and the longitudinal movement of the articles to achieve three-dimensional space. Used to handle and load cargo.
The above-mentioned metal structural components are reasonably arranged by various devices, so that the bridge crane can be used not only for loading and unloading in open-air warehouses, storage yards, railway freight stations, ports, etc., but also equipped with various special hooks. Carry out various special businesses.
There are also rules regarding choice. Under normal conditions, the lifting capacity is less than 50 tons, and the maximum hoisting machinery span is within 35 meters. It is recommended to use single-girder bridge cranes without special requirements. If the width of the door legs is required, the working speed is high, or heavy and long parts are often lifted, then a double-beam portal crane is required.
During operation of an overhead crane, slipping sometimes occurs. In order to eliminate this undesirable phenomenon, it is necessary to first analyze the cause of slippage and take corresponding measures according to different reasons.
For example, the correct selection of a bridge crane matching motor should not be too large; at the same time, the bearing capacity of the bridge crane and the load capacity of the wheel load should be calculated to ensure that the wheel has sufficient pressure on the wheel surface. In addition, the starting and braking time of the equipment must be properly controlled.
