CatchBlock OHL Catenary Roller From Slingco

Slingco has developed a range of products to vastly improve conductor replacement. The Catchblock, the Conductor Replacement Roller (CRR) and our range of specialist cable socks and grips.

The challenges faced by the OHL (Overhead Line) industry due to the growing number of electrical infrastructure projects built beneath existing transmission and distribution networks – alongside increasingly stringent OHL regulations – can make maintenance costly, time-consuming and challenging.

Replace OHL conductor in half the time with no need for possession orders


CatchBlock

Lightweight, robust and easy to deploy, CatchBlock helps to increase efficiency and reduce costs.

CatchBlock is an innovative overhead line (OHL) catenary roller system.

A two-rope system, allowing the replacement of old-for-new conductors. In the event of conductor failure during this process, Catchblock enables the recovery of both ends without having to lower the system.

Removes the need to erect and dismantle scaffolding, significantly reduces the risk of accidents and harm to site workers and reduces cost and project timeframe.

Designed to deploy a twin-rope system, it allows the recovery and redeployment of broken conductors without the need to take possession of road/rail or client/third party property or infrastructure.

CatchBlock Features & Benefits

  • Removes the need to close down essential infrastructure for conductor repairs or in the event of an emergency
  • Cuts down the need for scaffolding, reducing accident risk
  • Lightweight, robust, weatherproof and easy to deploy
  • Twin rope system allows for recovery and redeployment
  • Flexible – CatchBlock isn’t specific to a single tug design
  • High conductor range, including the ability to allow mid-span joints/repair sleeves to pass through safely
  • Blocks can be connected for use on multiple bundle conductor systems

Conductor Replacement Roller (CRR)

Provides a simple, conductor-deployed protection system using a lightweight aramid rope.

The CRR unit enables the safe exchange of conductors in three easy steps:

  1. Laying out the pulling cable, e.g. with an electric pulling robot.
  2. Tensioning the CRR Block assembly.
  3. Feeding a new conductor through the cable pulleys of the CRR Block.

The rollers have a spring loaded gripping feature to secure the rope laterally without impinging any rotational movement as the rollers rotate around the axis of the conductor.
