How rust chain hoists

1, chain hoist hook bearing, to inject calcium-based anti-rust grease to rust.
2, the various parts of the body hoists have been machined surface of an exposed table exposed threaded surface, painted barracks or other calcium-based grease rust rust grease.
3,manual hoist body gear box, gear should be coated with anti-rust grease oil barium sulfate, and shall be regularly inspected corroded and protection. Such as rust, chip or bamboo hardwood hang required to re-rust oil coating; such as the original film has gone, need clean kerosene or gasoline, and then Tu foregoing antirust grease.
4, 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.
5, maintenance and repair should be carried out by institutions more familiar gourd, 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.
6, gourd after cleaning and maintenance, load test should be conducted to confirm working, reliable braking can be delivered.
7, the brake friction surfaces must be kept clean.
8, left and right 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.
9, lift hoist 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 , the friction brake is pressed against the base sheet, counterclockwise rotation braceletsWheel, 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).
8, in the refueling process and the use of Chain Block, brake friction surfaces must be kept clean and regularly check the braking there, to prevent brake failure caused by heavy objects from falling.
