What Is MARSHINE Overhead Line Mounting Roller?
The MARSHINE Overhead Line Stringing Blocks Aerial Mounting Roller is a commonly used tool in the construction of overhead transmission and distribution lines. It is intended to hold and guide conductors in the stringing process, and allows them to move easily with minimal friction and protects the surface of the cable. Can be used to mounted on towers or poles, this aerial roller is an essential component in the enhancement of installation efficiency, safety, and cable integrity.
So How To Use MARSHINE Overhead Line Aerial Blocks Properly?
Preparation
Before you start using the MARSHINE Overhead Line Stringing Blocks Aerial Mounting Roller, please:
Check The Roller
Make sure all sheaves are free rotating and no visible damage (such as cracks, deformation).
Verify Load Rating
Make sure the roller is rated for the size and weight of the conductor.
Get The Mounting Hardware Ready
Make sure the brackets, hooks, and fasteners are all accounted for and in good condition.
Choose Installation Sites
Select tower or pole locations for the roller installations.
Wear PPE
Helmets, safety harnesses, gloves or any other applicable safety equipment should be worn when working at heights.
Installing The Roller
Position the Roller
Choose the appropriate mounting location on the tower, arm or clamp.
Make distribution conductor bends as required bend the conductor where its path requires.
Secure the Roller
Secure the roller with the clamps or hooks etc provided.
Tighten the screws enough to keep the stile roller stable while loaded.
Confirm Alignment
Make sure the roller is in line with the rollers on either side along the stringing line.
A good alignment means there are no roller bearing or radial shaft loads on the conductor passing through the conductor smoothly without friction or riding out.
Tensioning the cable
After installing the rollers:
Raise The Conductor
With the use of lifting devices like hoists or cranes, place the conductor on the MARSHINE Overhead Line Stringing Blocks Aerial Mounting Roller.
Put The Conductor In The Block
The cable should rest properly in the groove of the roller or the sheave.
Start The Drawing Process
Operate a winch or tensioner to draw the conductor through the roller.
Keep Things Moving Smoothly
Pull at a steady pace to prevent sudden tension or jerk.
Keep An Eye On It
Watch the conductor at each roller on the way to make sure it runs smoothly and is well centered.
