Product Description:
Cable roller, which is also referred to as cable pulley or cable
support roller, is an important device utilized in cable systems.
It performs some crucial functions, including:
1. Reducing Cable Tension
Cable pulleys can efficiently reduce cable tension, especially in
areas where the cable route has bends or changes in direction. By
offering appropriate support, it helps to decrease the stress on
the cables and avert them from being damaged due to excessive
tension.
2. Preventing Cable Wear
Cable pulleys possess a smooth surface that is designed to reduce
friction between the cable and the pulley. This helps to avoid the
surface wear of the cable and prolong its lifespan.
3. Maintaining Cable Routing
Cable pulleys are an effective means to keep cables in a specific
direction, thereby ensuring the overall structure and layout of the
cable system. This is fundamental in maintaining the stability and
reliability of the cable system.
4. Adapting to Various Environments
Cable pulleys are usually made of durable materials that can adapt
to different environments such as outdoor, indoor, high or low
temperature, and other conditions. This enables them to run
reliably in various application scenarios.

Features:
The cable ground roller is designed to be used for cables with a
diameter less than 200mm. It comes with both a nylon and aluminum
sheave for optimal use.
The triple sheave cable roller is specifically designed for larger
diameter cables that need to pass through. They can be built up at
arbitrary turning angles according to specific requirements.
The cable entrance protection roller is intended for cable
extension. It can be placed at any angle in the tube entrance and
has a lockable zinc-coated steel surface with a single nylon sheave
for smooth movement.
The D series cable entrance protection roller is equipped with an
enhanced length fixed mechanism and has a single nylon sheave for

The cable pithead roller is an ideal solution for protecting the
cable and pulling rope on the pithead.
Applications:
Guiding and supporting cables is an essential aspect of cable
management to maintain the integrity and safety of cable systems.
Cable pulleys play a critical role in this process by being
installed at the bends of cable lines.
The main purpose of cable pulleys is to guide and support cables
through multiple points in the system. By doing this, the pulleys
ensure that the cables move along the designed path and do not sag
or twist under the weight of the cables themselves or other
external factors.
Cable pulleys are especially useful at bends in the cable line,
where cables can be susceptible to damage or malfunction without
proper guidance. When installed correctly, cable pulleys can
effectively prevent these potential issues and ensure the optimal
performance and safety of the cable system.
