Chain hoists maintenance methods

1 after use should be cleaned and coated with rust gourd oil, stored in a dry place to prevent rust and corrosion from moisture chain hoists.


(2) Maintenance and service agencies who should be more familiar with gourds, gourd cleaning parts with kerosene in gear and bearing parts, add grease lubrication, to prevent the performance of the machine do not understand the principle of free disassembly.

3 gourd After cleaning and maintenance, load test should be conducted to confirm working, reliable braking can be delivered.  Rope hoist

4 brake friction surfaces must be kept clean. Brake parts should be inspected regularly to prevent brake failure occurred weights from falling phenomenon.

5 around sprocket chain hoists lifting roller bearings, used butter has been pressed in the adhesion lifting sprocket mounted on the inner ring of the bearing journal, and then into the wall of the bearing outer ring.  Hoist equipment

6 chain hoists installed brake parts, pay attention with the pawl ratchet pawls engage alveolar good spring pawl control should be flexible and reliable, installed after the chain started, bracelet wheel clockwise, it will ratchet , pressed the brake friction plate seat, counterclockwise rotation bracelet wheel, ratchet gap should be left between the friction plate.

7 In order to maintain and easy removal, hand chain in which a series opening chain (not welded).  chain block

8 In the refueling process and the use of chain hoists, brake friction surfaces must be kept clean and regularly check whether the braking and prevent brake failure caused by heavy objects from falling.
