About Three Sheaves Aerial Roller
Three Sheaves Aerial Roller
The three sheave aerial rollers are gravity die casted aluminium alloy sheaves, which are mounted
on sealed ball bearing and groove lined with neoprene/natural rubber flaps (Shore hardness 60-70 shore A with minimum thickness at bottom of the groove of 6.5 mm & tensile strength of 130 - 200kg/cm2) for conductor protection. They are mounted on fixed steel frames with standard plate attachment.
A Three Sheave Aerial Roller is specialized equipment for installing and maintaining overhead power and telecommunication lines, designed with three grooved wheels (sheaves) to guide and support cables during stringing operations. Made from durable materials like aluminum alloy, it features ball bearings and protective rubber lining for smooth movement and reduced friction. Its sturdy frame, often steel, includes a yoke and hanging plate for secure attachment to poles, ensuring efficient, safe, and damage-free cable handling across various terrain.
-
Three Sheaves:
This design minimizes friction and supports multiple cables or large diameters, leading to efficient installation.
-
Durable Construction:
Built with strong frames (often alloy or mild steel) and high-quality sheave materials (like aluminum alloy or nylon), it's designed for longevity in harsh conditions.
-
Protective Sheave Linings:
The grooves of the sheaves are often lined with neoprene rubber flaps to prevent damage to the conductor.
-
Smooth Operation:
Sheaves are mounted on ball bearings for low-friction, smooth rotation, allowing the cable to move freely.
-
Secure Hanging System:
Features a yoke and hanging plate for reliable attachment to utility poles or other structures.
-
Robust Clamping:
A secure clamping mechanism allows for quick and safe installation on site.
-
Overhead Line Construction:
Used to string and guide cables during the initial installation of power and telecommunications lines.
-
Line Maintenance:
Essential for maintaining the proper alignment and position of overhead cables.
-
