Product Description
Why the frame changes a heavy pull
A cable roller that carries its own frame is a different tool from a loose sheave. The frame fixes the roller height, keeps the roller axis square to the pull direction, and spreads the reaction load into the trench floor or the ground over a wider footprint. On large conductor and HV cable work that difference decides whether the cable runs in a straight line or walks sideways as tension builds.
The SHD range uses a 60mm carrier roller set in a four or six roller frame, rated at 20KN, with a maximum cable diameter of 180mm. Frame weights sit at 16KG to 20KG, light enough for a two person carry along a trench but heavy enough to stay put once seated.

Decoding the model code
- The first number after SHD is the carrier count: 4K carries four rollers in the frame, 6K carries six, which spreads contact over a longer length of sheath.
- The final 180 is the maximum cable diameter in millimetres, not the frame width.
- The trailing L marks a catalogue variant of the same frame and load class. Confirm the difference on the drawing for the item number you order rather than assuming the L units are interchangeable.
Setting up on site
Seat the frame so the first carrier line sits below the cable path and the last one is level with it; a frame set nose down will lift the cable off the rollers on the exit side. On soft trench floors put a plate or a sleeper under the frame legs, because the 20KN rating assumes the frame is supported, not bridging. Walk the frame after the first few metres of pull and check that it has not crept: a frame that shifts under load adds a sideways component the cable was not planned for.
Checks before dispatch
- Every carrier roller turned by hand; no flat spots, no binding.
- Frame alignment checked across the carrier line, not just at the corners.
- Weight and carrier count matched to the ordered item number.
- Plywood case packing with the carrier line protected so rollers do not take the load in transit.
Scope of the published data
The item numbers, carrier counts, diameters, rated load and weights above are transcribed from the current SHD datasheet. This page does not quote a percentage reduction in pulling tension, does not claim the frame fits every trench width, and does not state a certification beyond the ISO entry in the attribute table. Where a project specification needs a load test certificate, raise it with the enquiry so the correct document is quoted with the order.
Buyer questions
Four carriers or six?
Six carriers spread contact over a longer length of sheath and are the usual choice for stiff HV cable. Four carrier frames suit shorter cable and tighter trench space.
Can the frame be anchored?
The frame is designed to sit on a prepared surface. Share the site fixing detail with the enquiry and we will confirm what the frame allows.
Is the 20KN figure per roller or for the frame?
Treat 20KN as the frame rating and confirm the figure for your item number on the datasheet before the pull is planned.
