Hand chain hoist maintenance and maintenance method

As a commonly used lifting tool, the hand chain hoist is very important for maintenance. It must be used after the chain hoist has been used for timely maintenance. Handle hoist maintenance should pay attention to the following points:

First, it is forbidden for personnel who do not understand the principles of chain hoists to operate at will.

Second, it is forbidden to apply grease to the brake friction surface of the chain block. It is necessary to carry out the no-load test before use and confirm that everything is normal.

Third, after the use of chain hoists chain hoists should be cleaned, coated with rust-proof grease, and stored in a dry place, to prevent the occurrence of corrosion.

Fourth, install the gear of the chain block to strictly install the drawings for operation, after the installation of an empty inspection experiment.

5. When the braking mechanism of the chain block is installed, attention shall be paid to the engagement of the ratchet tooth slot and the pawl claw. After installing the upper sprocket, first rotate the sprocket wheel clockwise so as to press the ratchet wheel and the friction plate tightly to the brake. Seat.

6. Every year, personnel familiar with the hoist mechanism should clean the parts with kerosene and lubricate the gears and bearings.

The “ o ” word mark of the seven or two gears is installed on the same straight line.

VIII. When installing the brake device, pay attention to the good meshing between ratchet teeth and ratchet pawl, and the control of the pawl by the spring should be flexible and reliable. After the sprocket is mounted, turn the sprocket wheel clockwise. The ratchet wheel and the friction plate should be deposited on the brake seat. Turn the sprocket counterclockwise and leave a proper gap between the ratchet wheel and the friction plate.

Nine, support rod and the right wall plate for interference fit, is strictly prohibited to remove, so as not to loosen.

10. The friction surface of the brake must be kept clean during refueling and use. The brake part should be checked frequently to prevent the failure of the brake causing the heavy object to fall.

Through the maintenance of these points, the operation of the chain hoist can be made safer and unnecessary safety accidents can be avoided.

Note: Once every six months.
