If the hoist is not used frequently, the hoist should be parked in a dry room. If you have to park outdoors, you should choose a flat ground and lay out wooden boards. Cover it with a cover after parking. Before long-term storage, the inside of the winch hoist must be maintained, damaged parts repaired, and thoroughly cleaned to keep it in good technical condition. The arrangement and layout of the parking area should ensure that the entry and exit of any winch hoist machinery is not affected by other machinery. The mechanical fuel control lever should be placed in the idle position and each joystick should be placed in the neutral position. Storage of electric motors. Drain the cooling water in the winch hoist motor. Replace with new engine oil. New engine oil is usually neutral and will not corrode the metal parts of your engine. ③ Fill the fuel tank with diesel to prevent the fuel tank from rusting. Preservatives should also be added if conditions permit. During the shutdown period of the winch hoist, the engine should be started once a month to allow the winch hoist machinery to travel a short distance so that a new oil film can be established in the lubrication parts of each part to prevent rust. It should be noted that the cooling water should be filled before the winch hoist is started, and the cooling water should be drained when it is completed. Carry out anti-rust treatment on the surface of the machine. Before storing the winch hoist, the size of the peeling area of the anti-rust paint on the outer surface of the winch hoist should be considered to determine whether to use touch-up paint or re-paint the whole machine for repair. For working equipment, the anti-rust method for exposed metal parts is to apply butter
