The cable pulley series provides a conductive form for the crane trolley. It is composed of a walking wheel, a bracket and a pallet. The flexible cable is fixed on a pallet and the traction frame is synchronized with the I-steel cable pulley so as to achieve the power supply purpose of the cable.
Cable pulleys are divided into medium-load type, heavy-load type and light-load type. Therefore, the trolley traveling wheels are of three types of 86, 73 and 55, and the carrying capacity is less than or equal to 50-150 KG. Each type is divided into single layers and double layers according to the number of pallet layers. Layers, three layers, there are three types in each category, the first end of the cable tractor, the terminal is a fixed cable rack, the middle I-beam cable pulley.
1. After the fixed wire rack is installed, a blocker should be welded behind.
2. Adjust the traction head so that the trolley does not touch the upper and lower edges of the traction hole throughout the entire journey.
3, the cable length is 1.2 times the crane span plus 8 meters.
4. Adjust the traction wire rope so that its length is less than the length of the same cable, and the traction wire rope is forced when running.
5, when the cable diameter is not equal, the cable clamp pad with a soft rubber, so that the outer diameter is basically the same, in order to clamp the cable.
6. When distributing cables, consideration shall be given to the balanced force of the two cable trays.
7. When the cable pulley is in the second floor or the third floor, the requirements are the same.
8. The double washers on the pulley device are adjusting washers. When the guide rails are not suitable, the washers are placed on the inside of the fixing plate to adjust the width of the rules.
