Castor: if the activity is too loose, should be replaced immediately. Such as castor central rivet nut is fixed, shall ensure that its locked firmly. Such as activity can't free rotation, should check the ball in the presence of corrosion or dirt. If there is a fixed type caster wheel assembly, shall ensure that castor no bending phenomenon. The wheels: visual inspection abrasion of the wheels. The wheel rotational impeded associated with fine impurities such as red, the rope. Anti-wind can cover Yin in the clutter. Castor too loose or too tight is also another factor, replacement of the damaged wheels to avoid the unstable rotation. Inspect and replace the wheel after, shall ensure that use lock washers and nut tightening wheel axle. Because of loose axle can lead to friction wheel with stents and jammed. Replace the wheels and bearings should be to avoid the loss. Lubrication: add lubricating oil regularly, pallet car bearing casters and activities can be use for a long time. Put grease on shaft, sealing ring and roller bearing friction parts, can reduce friction and make more flexible rotation. Under normal circumstances once every six months for lubrication. The car in a month after cleaning for wheel lubrication. User competitors move hydraulic pallet car castor responsible for proper maintenance and operation. To avoid improper use or equipment, have to overload, heavy to light on the cart. Rough pavement of high speed or heavy pressure wheels will cause the wheels or equipment damage. Therefore, please check: stents and fasteners: the loose wheel shaft and the nut tightening and check weld or support plate for damage. Overload or crash will lead to distortion. Stent deflects the overloaded pressure distortion on individual round wheels and cause premature failure. If it is lever type caster, should be to tighten the nut or solid rivet and ensure equipment mounting bracket without bending and pole installed correctly. Should be used when installing truckle lock nut or locking washers. Expansion plug pole of castor installation to ensure that the plug rod firmly installed in a casing.
