The Importance Of Cable Pulling Rollers

The Importance Of Cable Pulling Rollers

As an electrician or network installer, you know running cables through conduits and raceways is necessary but tricky. Cable pulling rollers are essential tools. They make the job much easier and safer for your cabling.

What Are Cable Pulling Rollers?

Cable-pulling rollers are devices made up of one or more rotating wheels. We lay cables lengthwise over the wheels. This allows the cables to go through conduits. While being pulled, they protect the cable from binding and friction. The rollers distribute the pulling tension over the cable.

Other names for cable pullers include wire pulling rollers, cable guides, cable feeders, pulley wheels, and cable rollers. They come in many sizes to handle cable diameters from under 1/2 inch to over 5 inches.

Benefits of Cable Pulling Rollers

There are many advantages to using cable pullers:

  1. Prevent cable jacket binding, kinking, snapping, and friction damage.
  2. Enable long, continuous pulls in a single pass rather than increments.
  3. Minimal manual effort since rollers reduce pulling tension and resistance.
  4. Protect inner conductors from stress and distortion and maintain integrity.
  5. Suitable for copper wiring, fiber optic, and other data cables.
  6. Allow cables to be pre-assembled and rolled onto the feeder for easy installation later.

Types of Cable Pullers

There are three main types of cable-pulling rollers:

  • Standard rollers – Simple fixed cylinders suitable for straight runs. Most cost-effective.
  • Swivel rollers – Wheels pivot to align with cable movement around bends. Prevent snags.
  • Powered rollers – Motorized to pull the cable actively. Reduce manual work.

Specialty rollers like v-groove rollers and rubber-coated rollers are also available.

Cable Puller Components 

Cable pulling rollers consist of:

  • Wheels – typically steel or durable composites. A larger diameter provides more cable support.
  • Axle – connects wheels and may allow swivelling. Stainless steel or aluminium.
  • Frame – holds axle and wheels in place during pulls. It is made of powder-coated steel.
  • Mount – attaches puller to floor/ceiling/wall depending on pull direction—usually clamps.
  • Guiding supports – guide cable into rollers and maintain alignment. Funnel-shaped.

How To Use Cable Pullers

  1. Determine the required puller size based on your cable diameter. 
  2. Place rollers along the cable pathway at regular intervals of 8 to 15 feet.
  3. Attach a pulling line like a rope to the end of the cable.
  4. Position cable over rollers, line it up through the centre, and keep some slack.
  5. Attach the pulling rig to the rope and lubricate the cable and conduit as needed.
  6. Start the pull, allowing rollers to spin freely and guide the cable into the conduit.
  7. Walk along the path during the pull, resetting rollers as needed.
  8. Remove rollers at the end and neatly coil any excess cable.

Tips for Success

  • Stagger rollers top to bottom so cable contacts half the wheel each turn. 
  • More frequent rollers are needed for longer cable runs.
  • Keep slack in the cable to prevent binding against rollers.
  • Apply lubricant to the cable and conduit interior to minimize friction.
  • Larger-diameter wheels better support heavy cables with less bending.
  • Swivelling rollers are ideal for routing around bends and corners.
  • Stay within roller and cable capacity limits to avoid damage.

Why Cable Pullers Are Essential

Trying to manually pull cables over 50 feet without rollers risks binding, snapping, and friction damage. At best, the cable jacket will be scuffed and abraded. At worst, inner conductors will be stressed and deformed, leading to signal loss or shorts.

Investing in quality cable-pulling rollers saves hours of labour. It also avoids injuring cables during installation. For electricians and network installers, they are inexpensive but invaluable tools. Equip your workspace with the right selection of cable pullers. This will ensure smooth, fast, and safe cable runs every time.

Mistakes To Avoid While Installing Steel Wire Rope

Industrial steel wire ropes are made to be extremely strong and resilient. They are suitable for various applications and can withstand pressures of up to a thousand pounds. However, problems with installing steel wire rope can significantly reduce its longevity, capacity, and durability. Wire ropes can make the environment unsafe if they are not used properly. Even if the load it supports is less than its maximum load limit, the rope is still susceptible to snapping. Proper wire rope installation can easily avoid many of these common accidents. The following are the most typical errors to avoid when installing steel wire rope:

Not using clips and applying insufficient torque.

Manufacturers specify the ideal torque for their wire clips. If the steel wire rope is given insufficient torque, it may slide through the clips. If the threads are over-torqued, the rope’s strength may be compromised. Depending on their thickness, wire ropes require a minimum quantity of clips. Typically, the more clips it needs the larger its diameter.

Wrong way of unreeling wire rope

As it keeps the rope from tangled or crushed, wire ropes are reeled onto spools for simple handling and shipping. However, uncorrected unreeling of the wire rope can result in severe damage, including snagged wires, twists, kinks, or unraveled strands. Unreeling the wire rope by laying the spool vertically on its axis is a standard error that is frequently made. As the wire rope is yanked from the spool, it is more likely to twist or become kinked. When the wire rope is unreeled, it should not touch the ground as this could harm the wires. Instead, the reeled wire rope must be mounted on a shaft that enables 360-degree spool rotation. It should also require two people, one to slowly unwind the rope and the other to manage the turn rate to control the speed.

Incorrect method of cutting wire rope

To prevent the strands from unraveling, a steel wire rope is tightly wound around the end of the rope after it has been cut at a straight angle. There are two ways to safely hold a wire rope. First, it can be positioned at a right angle to where the seizing begins and ends. After that, the wire is wrapped around the angled piece to keep it in place, and the ends are then twisted together to keep it in place. Another choice is to encircle the two end pieces with the seizing wire and twist them together to form a tourniquet-like attachment. The kind of end preparations that are advised relies on a number of variables. Along with the number of wires and strands, this also includes the rope’s diameter. The wire rope’s core or strands could slip and unravel if these instructions are not followed.

Bottom line

Lowering the risk of steel wire rope hazards on the job site must be given top priority. Installation, handling, or storage errors with wire rope can have a severe negative impact on safety. Enforcing the proper use of high-quality wire rope is one of the simplest ways to achieve an appropriate installation.
