What is the type and classification of the crane?
In the driver mode: one type of drive, which drives the active wheel on both sides with an electric motor drive the long drive shaft. The other type is driven by an electric motor, which is driven separately by the active wheel on both sides. More medium and small bridge crane brake, reducer and motor group synthesis drive mode, the integration of the "triad" big lifting weight of ordinary bridge crane for ease of installation and adjustment, drive often adopt universal coupling. According to structure form, the crane is mainly divided into small light lifting equipment, bridge frame (bridge, gantry crane), arm posture (self-propelled, tower, portal crane, rail, pontoon type, mast crane), cable type.
According to different classification of the structure of the crane girder crane, bridge crane, gantry crane, mobile cranes, cantilever crane, tower crane, cable crane and ship crane, vehicle bridge, etc. Girder crane is: the beam crane mainly includes single beam bridge crane and double beam bridge crane The moving crane includes: truck crane, wheel crane, chain crane, all-terrain crane and cross-country crane. The cantilever crane has three forms: column, wall and balance crane The gantry crane has: tyrotype, orbital The model is too much to say.
Small lifting equipment Light and small hoisting equipment is characterized by light, compact structure, simple action, and a range of projective points and lines. Light, small lifting equipment, usually only one lift mechanism, it can only make heavy weight to make a single lift movement. Among them: jack, block, hand (gas, electricity), hoist, etc. Electric gourds are often fitted with running cars and metal frames to expand the scope of the work. The CD1 and MD1 series of steel wire rope electric hoist are based on the original CD and MD type. It has compact structure, lightweight, safe and reliable, large parts of general degree, strong interchangeability, high lifting capacity, maintenance is convenient wait for a characteristic, is widely used, popular light lifting equipment.
According to the structural characteristics of crane machinery, there are four types: Light small lifting equipment Bridge type crane equipment Three-arm frame type crane Lift crane You can leave a message for me if you want to know more about the four categories
Lifting machinery used in bridge engineering, according to its structure and properties of different, general can be divided into small light lifting equipment, bridge type crane hoisting machinery and boom type, cable crane four categories. Light and small lifting equipment such as jack, pneumatic gourd, electric gourd, balance gourd, winch and so on. Bridge type crane machine such as beam crane and so on. The arm frame type crane, such as fixed revolving crane, tower crane, truck crane, tyre crane, crawler crane, etc. A cable crane is like a lift. Moving crane, tower crane, mast crane.
