With a frequency conversion system, it converts DC into AC, by controlling the AC motor drive on drive wheels. - Page 7 pins, the brake pads will move to the rotation direction of brake drum. The friction between brake drum and friction plate is then increased. Double brake pads are mounted on both sides of the drive axle. Brake consists of two groups of brake pads, brake cylinder and regulator. One end of the brake pad is in contact with the fixed pin, and the other end is in contact with the adjusting calipers.

Wheels: Quality of the wheels has significant effect on stability and driving performance of the stacker. Modification on wheels can be performed only with the approval from the manufacturer. When replacing wheels, ensure that the stacker is levelled as delivery state(wheels must be replaced in pairs, i.e. replace right wheel together with left one). - Page 19 Maintenance periods listed in this manual apply to single shift a day under normal operation conditions. If using in dusty environment, the ambient temperature varies remarkably or in multi-shift situation, the maintenance period has to be shortened. Maintain the stacker according to following maintenance list. Maintenance periods are as follows: W1 = Every 50 work hours, but at least once a week.
