During the operation of the winch, observe and check the function and wear of the brake, clutch and stop at any time, and remove the fault in time. Under normal operation, overhaul shall be carried out every time (about one year) or after the completion of a construction period, replacing worn bearings and other vulnerable parts, and repairing shall be carried out at any time when problems are found.
When transporting and maintaining the construction winch, it shall be placed in a dry place, and each component shall be provided with good moisture-proof, corrosion-proof and other measures.
In the process of disassembly and assembly, pay attention not to damage the mating surface, check the wear condition of friction surface, the condition of gears and bearings, the wear condition of rotating parts and connecting parts, the condition of electrical components, etc., and replace them in time if the use of the machine is affected.
The breakdown and treatment method of construction winch in work:
If the gap is too large after the brake is worn, which affects the brake reliability, adjust the gap or replace the components in time. If the bearing overheats due to wear or poor lubrication, improve the lubrication or replace the bearing according to its condition. If the bolts used to fix the bearing are not tight, resulting in the bearing heating, the bolts shall be tightened in time.
Due to the heating of overload motor or the heating of motor bearing, it is necessary to stop for cooling, refuel on time and reduce the load. Turn on the power switch before checking the electrical equipment, The electric appliance shall be kept clean, so as to remove dust, dirt, greasy, etc. regularly. It is not allowed to have oil on the contact. The burnt or oxidized contact shall be polished with fine sandpaper. The insulating ring shall not be washed with gasoline. In order to prevent rust on the contact surface of armature iron core, it shall be lubricated with machine oil regularly, and then wiped clean. Each section of resistor cast iron sheet shall be checked frequently to see if it is broken.
When the motor operates under rated load, the allowable unbalanced voltage is 5%, and the unbalanced current is 10%. In this case, attention shall be paid to whether the rotating sound of the motor is abnormal, whether there is spark between the brush and the slip, and whether the motor is heated, which shall not exceed the allowable value.
