Rough cranes on the rough road or heavy objects will cause the wheels or equipment to be damaged. Therefore, check the brackets and fasteners regularly. Put the loose axle and nut tight and check for damage to the weld or support plate. Overload or impact will cause the bracket to deform. And the deformation of the bracket so that heavy dump pressure on the individual wheels and lead to premature damage to the wheels. If it is a rod type wheel, tighten the nut or tighten the tightening and ensure that the device bracket is not bent and the plunger is installed correctly. Locking nuts or lock pads should be used when assembling casters. Expansion of the plunger device to ensure that the plunger firmly installed in the casing. Lubrication: Regularly add lubricants, wheels and movable bearings to long-term use. Apply lubricating oil to the wheel, seal and roller bearing friction parts, can reduce the friction and make the rotation more flexible. Under normal circumstances every six months to carry out a lubricant. The car should be lubricated after the monthly cleaning. Wheels: visually check the wheel wear. Wheel rotation is not smooth and fine red, rope and other debris related. The anti-wrap can block the entanglement of these debris. Casters do not loose or too tight also, the timely replacement of broken casters to avoid unstable rotation. After checking and replacing the wheels, ensure that the wheel is tightened with the locking washer and nut. Because the axle loose will cause the wheel and the bracket friction and stuck. Replacement of wheels and bearings should be provided to avoid loss of production. Activity shift: If the activity is too loose, be replaced immediately. Such as casters center rivets are nuts fixed to ensure that the lock is firm. If the activities can not be free to turn, should check the ball at the corrosion or dirt. If equipped with a fixed casters, to ensure that the casters bracket without bending phenomenon.
