Maintenance method of manual chain hoist block

1.After use the manual chain hoist block should be cleaned and coated with antirust grease, stored in a dry place to prevent the manual hoist damp rust and corrosion.
2.Maintenance and repair should be operated by professional staff, cleaning manual hoist chain pulley block parts with kerosene, add butter lubrication in gears and bearings.
3.Chain pully block after cleaning and maintenance, should be carried out in the no-load test, to confirm the normal operation, can be delivered to use only if the brake is reliable.
4.The friction surface of the brake must be kept clean. Brake parts should be checked regularly to prevent the brake failure and the occurrence of heavy load from falling.
5.The chain pully block lifting sprocket around bearing roller, the grease can be adhered to the bearing inner ring which is pressed on the neck of the lifting chain wheel shaft, then the bearing outer ring into the wall.
6.When in the installation of the brake part of the manual hoist chain pulley block, pay attention to the tooth groove of the ratchet wheels and ratchet pawl meshed well or not, spring on the pawl control should be flexible and reliable.Fitted on the bracelet wheel, clockwise rotate the bracelet wheel, press the ratchet wheel and friction plate on the brake seat, counter clockwise rotate the bracelet wheel, the ratchet and the friction plate should be left a gap.
7.In order to facilitate the maintenance and disassembly, one of the chain link bracelet (welding is not allowed).
8.In the process of filling and using chain pully block, the friction surface of the brake device must be kept clean, and the braking performance is always checked to prevent the weight from falling due to the failure of the brake.

How to deal with 3 ton electric chain hoist motor overheating

Any machine has the cycle and time of operation, is not suitable for a long time continuous operation. Long time operation will cause mechanical damage and even accidents, but in general if the 3 ton electric chain hoist surface temperature is too high, we need to check what is the reason. Firstly to check whether it is because the electric hoist weight is too large, beyond the 3 ton electric chain hoist rated weight. Overweight operation will make the motor over heating, overload for a long time will cause irreparable damage to the electric chain hoists for sale. Electric hoist motor is not overloaded, but still heating, should check whether the motor bearing damaged; Should also check whether the motor Work according to regulations, which is one of the reasons causing the motor heating. When the electric hoist motor is running, brake clearance is too small, not completely disengaged, causing great friction, while the frictional heating is also equivalent to the additi...

The reason of electrical wire rope hoist does not work after starting

Mainly because of the hoist does not reach to the rated operating voltage, there are generally 3 kinds of situations: 1.Find out whether the power supply system supply power to wire rope electric hoist , generally used test pencil, such as no power supply; 2.The main control circuit of the wire rope electric hoist is damaged, the line is broken or the contact is bad, can also let the hoist motor not be electrified. This situation, need to overhaul the main control circuit. When maintenance, in order to prevent missing phase to burn the motor casused by the main control circuit supply power to three-phase motor, or hoist motor suddenly operate and cause danger, must disconnect electrical wire rope hoist motor from the power supply, only supply power to the main control circuit. Then start and stop switch, check and analyze the working condition of the electric appliance and the line, repair or replace the failed electric appliance or line. When the main control circuit is confirmed...

Working level of overhead gantry crane

Overhead gantry crane installation site and the work conditions is vary greatly, the use of lifting capacity and working frequency are also different. In order to use the crane economically and reasonably, it is necessary to choose the appropriate working level according to the working condition of the crane. The working level of the bridge crane is divided into A1 ~ A8, according to the level of the crane and the load state, that is, according to the frequency and load degree of the crane through the calculation to determine. The crane has a certain number of working cycles during its useful life. A working cycle of a travelling gantry crane is to start the process of loading the goods from the beginning to the next. The total number of working cycles represent the utilization of cranes. In order to facilitate the calculation, the total number of working cycles can be divided into 10 categories. 200-400 ton heavy duty travelling overhead gantry crane for ...
