The daily maintenance of the hydraulic brake of the stage rigging hoist is of crucial importance. First of all, it is necessary to comprehensively check whether the cooling system of the stage rigging hoist is working normally. Carefully check the operation of the cooling fan, including whether the fan can start on time, run smoothly and have sufficient wind force. If the fan gets stuck, makes abnormal noise or stops running, it needs to be repaired or replaced in time; Check whether the cooling pipeline is unobstructed and whether there are bends, blockages and other situations. If there is impurity accumulation in the pipeline, it should be cleaned to ensure the smooth circulation of the cooling liquid; Check whether the liquid level of the cooling liquid is within the standard range and whether the quality of the cooling liquid is qualified. If the liquid level is insufficient, it should be added in time; if the cooling liquid deteriorates, it must be completely replaced.
Secondly, it is necessary to check whether the equipment is overloaded. Check whether the load of the stage rigging hoist exceeds its rated load. Overloading will make the brake system work under high load for a long time, increase the heat generated by friction and cause the oil temperature to rise. It can be confirmed by checking the equipment operation records and the weight of the loaded objects. Once overloading is found, the load must be reduced immediately to avoid continuous overloading operation.
