The Maintenance of Demag Wheel Block for Stackers

Routine Maintenance of Stacker Wheel System

 1. Check whether each open gear and coupling of the wheel set is equipped with a protective cover.

 2. Check the joint surfaces of each open gear and coupling for excessive wear.

 3. Check the running wheel tread. Since the tread has to withstand a lot of contact stress from the track, if the hardness and quality of the surface layer are not good, block peeling can be seen during inspection.

 4. Check whether the oil hole of the wheel set's running axle is smooth. If the oil line is blocked and butter cannot be added, it will cause the bearing bush to dry grind, and then the bearing bush will be crushed into pieces and run out, so that the four supporting points of the crane will be unequal, and the structure above the wheel set will be deformed, which will cause damage to the main structural welds and main connections. The location will cause stress concentration. A wheel without a bearing will move left and right while running, and the entire track will be worn and shiny.

 5. Check whether the fixing foundation bolts of the wheel group gearbox are loose. Due to the frequent movement of the crane and the huge inertial kinetic energy vibration, the foundation screws can easily become loose. If it is not tightened in time, the screw holes of the gearbox foot may be torn, which will affect the coupling and cause the operation of the truck to deteriorate.
