1. Prior to use, the use of the environment will be assessed to determine that there is no risk factors or the use of the Boat Hoist factors in the case of lifting work.
2. Lifting the weight of the process, the surrounding environment and the situation of heavy objects to observe, for the shaking of heavy objects and around the Shing walking conditions to avoid the occurrence of heavy objects can be avoided, and the loss of personnel.
3. A number of potential problems have been identified, which can be detected by the user, so as to detect potential problems, avoid problems, and affect operational safety.
1. The use of the gourd should be cleaned and coated with anti-rust grease, stored in a dry place, to prevent the Boat Hoist damp rust and corrosion.
2. Maintenance and overhaul should be carried out by more familiar with the gourd institutions, with kerosene to clean the gourd parts, gear and bearing part, add butter lubrication, prevent do not understand the principle of the performance of the machine at random disassembly.
3. After cleaning and maintenance, the hoist should carry out no-load test, confirm the work is normal, the braking is reliable, can deliver the use.
4. The friction surface of the brake must be kept clean. Brake parts should be checked regularly to prevent braking failure, the occurrence of heavy objects falling phenomenon.
5. Hand-pull hoist lifting sprocket around the bearing of the roller, can be attached to the butter is pressed in the hoisting sprocket shaft of the bearing inner ring, and then loaded into the wall plate bearing outer circle.
6. In the installation of the brake device part of the hand-drawn hoist, note that Ratchet gear groove and Pawl claw part of good meshing, spring on the Pawl control should be flexible and reliable,Boat Hoist put on the bracelet wheel, clockwise rotating bracelet wheel, will ratchet, friction sheet pressure on the brake seat, counterclockwise rotation bracelet wheel, ratchet and friction between the disc should leave a gap.
7. In order to maintain and disassemble conveniently, the chain of the hand chain is one of the opening chains (not allowed to weld dead).
8. In the refueling and use of the Boat Hoist process, the braking device friction surface must be kept clean, and often check the braking property, to prevent the braking failure caused by heavy objects fall.
