    Single beam cranes unload test requirements
    Single beam cranes unload test requirements

    1. The operation direction and the running direction of each mechanism of the single beam crane should meet the design requirements;2. Start the motors of each mechanism separately, the operation should be normal, and measure the no-load current;3. The operation of each safety protection device and brake should be accurate and reliable;4. Electrical equipment such as power distribution panels, cabinets, motors, controllers, etc., should work normally;5. Each operation and lifting mechanism should travel at least three times along the whole track, and there should be no abnormal phenomena;6. Th ...

    Wire rope electric hoist rope guide
    Wire rope electric hoist rope guide

    The wire ropes shall be arranged neatly in order on the reel, GB6974.4-1986 "Glossary terms and components of cranes" shall be interpreted as a rope guide, which can make the wire ropes align neatly at regular intervals.The working principle of the rope guide used in various electric hoists is similar. The electric hoist with single layer winding should be equipped with a rope guide to ensure that when the hook is lowered and the rope is free from other external forces, the rope can still freely move from the rope guide outlet. When raising and lowering, the angle of the wire rope to ...

    Crane machine lifting weight limiter
    Crane machine lifting weight limiter

    There are four types of lifting weight limiters: hook type, wire rope type, bearing type and fixed pulley type.1. The hook type weight limiter has three types: direct display type, frequency modulation launch type and separate type;2. The wire rope tension type uses a special fixture, and the sensor is installed on the lifting wire rope, and the tension of the wire rope is detected to reflect the load. This method is easy to install and has high detection accuracy;3. The bearing type sensor adopts double shear beam type or cylindrical shape, with special accessories, and is installed on the si ...

    Maintenance points for overhead crane coupling
    Maintenance points for overhead crane coupling

    The coupling is mainly used to connect the coaxial line or the two parallel shafts. The torque of the motor is transmitted to the low speed shaft through the reducer and the coupling to complete the load lifting, overhead crane and trolley running operation. Gear couplings will be worn due to mounting accuracy, loose anchor bolts, bridge deformation, poor lubrication, etc. Therefore, the coupling should be inspected frequently.The basic requirements for the inspection of the coupling: the connection of the coupling should be firm, the connecting bolts and the connecting keys should not be loos ...

    The crane machines quality testing

    Crane machines are widely used in workshops, warehouses, material yards, etc. in machinery manufacturing workshops, petroleum, petrochemical, port, railway, power station, papermaking, building materials, electronics, etc., with advantage of compact structure, low headroom, light weight, small wheel pressure, etc.1. Visual inspection: Check whether the specifications and status of all important parts meet the requirements;2. No-load test: After turning the various mechanisms without jamming, the various mechanisms should be able to operate normally, the limit switches can work reliably, and th ...
