Stringing pulley block is a special equipment for supporting various conductors and ground wires in overhead transmission line stringing construction, which plays a supporting role for ground wires. It does not damage wires and has small friction coefficient. It can pass through traction plates, connectors and pressure nozzles smoothly. Stringing pulley block is suitable for laying out single conductor overhead transmission line.
4. According to the customer's demand, aluminium wheel or MC nylon wheel can be selected.

Wire-rod has the problem of the dynamic tension fluctuation caused by interference when it is in the process of rolling, so it lead to the fluctuation of the dimension of the rolling element, vertical loop can eliminate part of the tension fluctuation to make sure the precision of the equipments.
2. The structure of Vertical loop:
Vertical loop is composed of sets of roll(it is pushed by cylinder), back-up roll and loop groove. The sets of roll used to form cover. Side-wall is used to support the element to form the loop. Loop adopt the central pole mount, which is easy to turn on and adjust the mill guide and guard
The diameter of sets of roll cylinder is Φ 160mm; Distance is 200mm.
The working altitude of loop is 100mm higher than the rolling centre line.
The highest altitude of loop is 400mm higher than the rolling centre line.
3, Lubrication and pneumatic:
The transmission parts of loop adopt glycerol manual lubrication.
The air used in loop and rear brakes is unified offered by workshop, the pressure to compressed air is around0.4~0.6Mpa.

According to the material, there are two kinds of aluminum wheel and MC nylon wheel, and the style is divided into tube type and plate type.
Application of large diameter stringing pulley: it is used to lead and stringing single conductor, double split conductor and four split conductor (the intermediate wheel can be cast steel wheel or nylon wheel), which is suitable for tension paying off.
Ground wire stringing pulley: it is suitable for extending lightning wires or crossing steel strands, including steel and MC nylon.
Special pulley for optical cable: it is used to lay OPGW composite ground wire optical cable or ADSS self-supporting optical cable. A small groove is equipped at the bottom of the wheel groove, which is specially manufactured to protect the optical cable; The wheel is made of MC nylon by die casting, which will not damage the outer skin of the optical cable during stringing.
Description:
1. We manufacture a lot of models for different uses in the overhead transmission line construction.
2. The stringing pulleys are used to support conductors, OPGW, ADSS, communication lines, etc.
3. The sheave of the pulley blocks are made from high strength MC nylon, or aluminum materials, and the frame of blocks are made of galvanized steel. The lateral ones are mounted on ball bearings.
