There are many ways to classify Crane factory, which can be classified according to working mode, structure, operation mode, etc., such as light and small lifting equipment, bridge cranes, fixed and mobile, etc. Lifting machinery should be maintained during use. The editor will give you a detailed introduction to the classification and maintenance of hoisting machinery.
1. Lifting machinery can be divided into three categories: cranes and lifts according to their working methods.
(1) Light and small lifting equipment mainly refers to hoisting machinery with only one lifting device. There are jacks, pulleys, electric manual hoists, etc.
(2) Crane refers to hoisting machinery that can be lifted vertically and transported horizontally. Such as bridge cranes (also called cranes or overhead cranes), truck cranes, tower cranes, etc.
(3) Lift refers to a hoisting machinery with a fixed position, a fixed lifting line, a wire rope traction, a slide rail restriction, and a cage. Including various elevators, winches, winches, etc.
2. According to the structure, cranes are divided into two types: and jib cranes.
(1) Cranes, metallurgical cranes, gantry cranes, and cable cranes are bridge cranes
(2) Portal cranes, tower cranes, truck cranes, crawler cranes, rubber-tyred cranes, and cantilever cranes are jib cranes.
3. Cranes are divided into stationary and mobile according to their operation mode.
(1) Tower cranes and cantilever cranes are fixed cranes
(2) Bridge cranes, tire cranes, crawler cranes, and railway cranes are mobile cranes.
4. How to maintain the lifting machinery?
1. Check whether the fuel of the engine (or starter) is sufficient.
2. Check whether the water in the water tank is sufficient.
3. Check whether the oil in the bottom case of the engine (or starter) is sufficient.
4. Check whether the oil in the control box is sufficient.
5. Check the working condition of the engine to see if there are oil leaks, water leaks, air leaks, and abnormal knocking sounds. Both low and high speeds need to run well.
6. Check the condition of the wire rope, especially the tightness of the connection.
7. Check whether the battery, generator, motor, horn, and lighting are in good condition.
8. Check whether each instrument is normal (check according to the regulations in the factory manual of various machinery).
9. Add lubricating oil to each part according to the lubrication period, lubrication parts and oil used in the various mechanical lubrication charts.
10. Check the working conditions of each mechanism, such as each clutch, brake up and down travel mechanism, boom, pulley, hook, etc. And carry out operation test, if any fault is found, it should be eliminated in time.
11. Clean the outside of the machine.
