10KN Rated Load One Way Corner Cable Roller for Route Direction Change Cable Pulling Roller

Scope of the SHZL1 Corner Roller Series

Corner rollers exist for one job: carrying a cable around a change of direction without letting the sheath take the load on a hard edge. The SHZL1 family is a frame mounted roller set rated at 10KN, supplied in one way and two way structures, with four item numbers covering the combinations. Because the roller sits in the frame rather than at the end of a strut, it can be pinned at a bend in a duct route, at the base of a riser, or at a pull pit corner and left in place while the pull progresses.

The four variants and what separates them

Structure is the only variable inside the series. The one way models carry the cable through a single turn; the two way models add a second roller axis so the same frame can handle a turn that reverses direction, which matters where a route leaves a pit and immediately bends again. Rated load is 10KN across all four, so the choice is made on geometry rather than capacity.

Verified specification table

How engineers read this table

• Start from the route drawing: count the direction changes a single pull will meet at that corner. One change points to the one way models, a reversal or compound turn to the two way models.
• Check the 10KN rated load against the calculated pull tension for the section, not against the winch capacity.
• Confirm the cable diameter clears the roller groove and that the frame footprint fits the available floor or wall space at the corner.
• Where the corner is also a vertical to horizontal transition, plan the frame mounting height before the pull date.

Practice notes from cable laying work

Corner rollers earn their keep when the frame is fixed. A roller that shifts under load simply relocates the problem, so anchor the frame first and check the anchor after the first few metres of pull. Keep the number of rollers in a corner to the minimum that still keeps the cable clear of the edge; a crowded corner adds contact points without adding control. On long pulls, walk the corner during tensioning, since that is where the cable will leave the groove first if alignment is wrong.

Inspection and packing

• Roller rotation checked by hand on every unit before packing.
• Frame welds and pin holes inspected; any burr in the pin hole is reamed.
• Rated load figure restated on the packing list for site reference.
• Plywood case packing, one unit per compartment, 400 PCS per month supply capacity.

Data notes and limits of this page

The four item numbers and the 10KN figure come from the current series datasheet. This page does not publish percentage gains in pulling effort, does not claim universal fit across roller frames of other makes, and does not assert a structural test beyond the ISO entry in the attribute table. Where a project requires a tension calculation or a load test certificate, raise it with the enquiry so the correct document can be offered with the quotation.

Questions buyers ask

What is the difference between SHZL1 and SHZL1N?

Both are one way structures at 10KN. Treat them as two build variants of the same function and confirm the variant marking on the drawing before ordering.

Do I need the two way version for a simple 90 degree corner?

No. A single direction change is the case the one way models were designed for. The two way models are for compound or reversing turns.

Can the frame be bolted to a pit wall?

Mounting depends on the site detail. Share the fixing arrangement with the enquiry and we will confirm what the frame allows.

What are the trade terms?

1 PCS minimum order, L/C or T/T, 3-7 days for stock, plywood case packing.
