Universal Description QD bridge crane maintenance and attention to points

Type QD general overhead bridge crane maintenance metal structural parts What? In addition to this, QD-purpose bridge crane safe handling precautions, but also we need to master, then, specifically including what content?First, the maintenance of the metal structural parts1 bridge maintenance(1) should be avoided sharp start, braking, or collide with the eot crane, in order to avoid the additional bridge a greater dynamic load deformation.(2) respond to the main beam deflection measurements carried out on a regular basis in order to see whether there is the main beam deformation.(3) some of the major welds, including the main beam, side beams and other parts, should be checked, if found cracks should immediately stop using, and then repaired. Repair welding, ensure the welding quality, prevent welding deformation.(4) If the residual deformation of the main beam, it should immediately stop using, and then resolved.(5) repair or reinforcement bridge, it should first conduct a trial run, test qualified to put into use.(6) Cranes shall be based on actual usage or operating environment, regular painting and maintenance.2 track maintenanceMainly to check whether the track straight, without bending, plate is loose, if loose should be tightened. If the rail trolley travel phenomenon occurs, then the response orbit correction or adjustment wheels.Second, the safe handling1 The crane must not exceed the rated weight of the heavy lifting. Lifting goods can not be crossed over from the people.(2) running in the air, the spreader position can not be less than the height of a man, heavy lifting spreader can not be inclined, to be vertical lifting.3 can not take advantage of the sudden reversal motor brake as an institution, and only in unexpected circumstances allow. But can not use limit switches as power outages under normal operation, and only in the case of poor control equipment used.4 cranes in operation, before a warning signal, so that evacuation to a safe area.5bridge gantry crane  lifting close to the rated load in raising the amount of weight, you should first check whether the brake stopped promptly, to ensure safety.6 crane does not operate, it should be in a fixed parking spots, which can not have spreader objects should be placed in zero position control handle, and cut off the main switch and the power to prevent accidental activation.
