1No.2 I-beam cable pulley GHC-II10#Product Introduction
The HC type cable pulley series is a conductive form of power supply for crane trolleys. It consists of a walking wheel, a bracket, and a support plate. The flexible cable is fixed on the support plate and synchronized with the cable pulley by the traction frame, thus achieving the purpose of power supply for the trolley.
The HC series cable pulleys are divided into medium load type, heavy load type, and light load type. Therefore, there are three types of pulleys for the pulleys, with a bearing capacity of ≤ 50 ∽ 150kg, which are divided into single-layer, double-layer, and three-layer according to the number of pallet layers. There are three forms in each type, with the first end being the cable traction vehicle, the terminal being the fixed hanging bracket, and the middle being the cable pulley (see figure below).

1. After the installation of the fixed cable rack, a baffle should be hung at the back.
2. Adjust the traction head so that the car 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 span of the crane plus 8 meters.
4. Adjust the length of the traction wire rope to be less than the length of the same cable section, and ensure that the traction wire rope is subjected to force during operation.
5. When the cable diameters are not equal, soft rubber should be placed between the cable clamps to make their outer diameters basically the same, in order to clamp the cables.
6. When laying cables, it is necessary to consider the balanced force on both sides of the cable tray.
7. When the cable pulley has two or three layers, the requirements are the same.
8. The double washers on the pulley device are adjustment washers. When the guide rail is not suitable, the washers are placed on the inside of the fixed plate to adjust the width of the track gauge. They are manufactured according to the guide rail specifications of I 100 * 68 * 4.5, I 120 * 74 * 5, I140 * 80 * 5, and I 160 * 88 * 6 at the factory. Non standard pulleys are processed and manufactured according to the drawings.
