Aluminum Cable Pulling Pulley Single Cable Laying Roller For Power Construction

Aluminum Cable Pulling Pulley Single Cable Laying Roller For Power Construction​

Pictured: Trench Cable Rollers

Cable rollers should always be used when pulling cables.
Straight cable runs are pulled in using straight cable rollers suitably placed in the cable trench to prevent the cable being dragged on the trench bottom or in mud.

Cable roller spacing is dependent on cable type being laid and the cable pulling tension along the route. Leading cable rollers are used to support the cable over the entire drum width immediately before being pulled into the trench.
Cable laying applications with bends in the route require skid plates of a radius greater than the cables minimum dynamic bending radius.

Cable Rollers & Cable Pulling Up To 33kV – Notes

Straight horizontal power cable runs should be supported on free running straight cable rollers, typically straight cable roller for cables up to 125mm diameter.

Where cables need to be pulled into narrow underground cable trenches, narrow cable rollers are recommended for cables up to 76mm diameter.

The cable roller spacings required depend on cable type being installed and the pulling tension along the route. V type lead-in cable rollers are used to support cables over the entire cable drum width immediately before being pulled into the cable trench.

Corner cable rollers are used to guide power cables through bends in the cable route. manhole cable rollers are designed to be placed at the end of the manhole or cable pit entrance to ease underground cable installations.

Uses

The uses of a cable pulley can vary, though the system is usually designed to lift heavy weights or move heavy objects over a length. Woven cables are much stronger than belts or ropes in most cases, so they are better prepared to handle the weight of larger objects. It is not uncommon to find a cable pulley in an industrial setting such as a warehouse or factory, or any other setting that requires the regular movement of extremely heavy objects. The size of the cable and the pulley will dictate how much weight the system can handle, as well as the number of pulleys in the system.

Features

Corner Cable rollers, the cable rollers are used in protecting the cable during cable-laying at the tunnel construction. So the cable can laying well enough to laying.
