(Summary description)When carrying out maintenance work, first of all, be aware of the danger of being dragged into the rotating pinion, the risk of crushing and shearing. When performing the following tasks, make sure that any maintenance workers are not in the danger zone between the main arm, the upper car and the reel, or between the disembarkation and the reel when starting the engine for the necessary revolving and luffing operations. In the danger zone, the crane operator (in the driver's cab) is excluded. Check the slewing bearing bolt 1. Before the crane works or at least once a week, visually inspect the bolts on the slewing ring; 2. After the slewing bearing works for 100 working hours for the first time, check whether the bolts are loose, and check again after the 300th working hour; Check every 500 working hours; shorten the inspection interval for bad conditions. If the bolt is loose during the inspection, please stop the construction work and immediately contact the local after-sales service department. The factory or professional technicians will make an inspection and decide whether to disassemble and inspect it immediately. 3. The slewing bearing is filled with lithium before installation. Base grease; 4, when replacing the bolt, wipe the bolt clean, apply screw fastening glue and tighten; use the crane according to the operation manual and lifting performance table, or check the fastening bolt regularly according to requirements, you can avoid The danger of bolt fatigue damage. Routine inspection of slewing bearings 1. Regularly check the flexibility of the rotation; if noise or impact is found, stop the inspection immediately, eliminate the fault, and dismantle the inspection if necessary; 2. Regularly check whether the rotating ring gear has cracks or breakage, and whether the meshing tooth surface has any bite, cut, or tooth surface peeling; 3. Regularly check the integrity of the seal. If the seal is damaged, it should be replaced in time. If it is found to fall off, it should be reset in time. Lubricate the tooth surface of the slewing ring The slewing ring gear is coated with anti-rust oil before leaving the factory. The anti-rust effective period is generally 3 to 6 months. After the expiration date, the anti-rust oil should be applied in time. In addition, in use, the slewing ring is protected from direct sunlight exposure. It is forbidden to directly flush the slewing bearing with water to prevent it from entering the raceway, so as to prevent the hard foreign matter from approaching or entering the tooth meshing zone. Lubricate the raceway of the slewing ring The raceway must be filled with grease regularly according to the working environment. After the first working 50 working hours, the raceway should be filled with grease and then injected once every 300 working hours. The slewing ring must be filled with grease before and after prolonged placement. If you use a steam jet cleaner or a fixed sprinkler to clean the crane, care must be taken to ensure that water does not penetrate the slewing ring connection and then the slewing ring connection must be lubricated. Special working conditions, such as tropical, high humidity, high dust, large temperature changes, and continuous operation, should shorten the lubrication cycle. Filling grease should be carried out with the slewing ring rotating slowly. When the grease overflows from the seal, the filling is completed, and the spilled grease will form a film to seal.
