A wire rope problem can stop a suspended platform in seconds — and most of the time, the cause is a few habits on site. In this guide, we explain why a traction hoist wire rope jams or kinks, and how to prevent it. The equipment behind every safer lift: RIGID Machinery.
Why Wire Rope Jams or Kinks in a Suspended Platform
A wire rope (also called steel wire rope) is made of small wires twisted into strands, and strands twisted into a rope. Under load, the rope naturally wants to twist. When it can't release that twist, two things can happen:
-
The rope jams inside the traction hoist.
-
The rope kinks — a permanent "dead bend" — when it goes slack.
Common Causes of Wire Rope Jamming and Kinking
-
Worn or damaged steel wire rope
-
Too much slack rope
-
A loose or frayed rope end
-
Debris in the traction hoist rope groove
-
Rope out of position on the sheave

How to Prevent Wire Rope Jamming & Kinking — 5 Habits
-
Keep surplus wire rope on the roof. On the ground, leave no more than 1 m — tie it up off the ground.
-
Never lay the top wire rope on the ground. Tie it up and hang it on the rear suspension bracket.
-
At the end of each shift, keep the suspended platform off the ground and the wire rope taut.
-
Replace qualified steel wire rope and service the traction hoist on schedule.
-
Operators of any suspended platform hoist or man-riding hoist must be trained by an authorized dealer.

Corrective Measures: When a Wire Rope Jams or Kinks
-
Jammed traction hoist wire rope? Stop. Never force it. Inspect, then jog slowly in reverse.
-
Kinked wire rope? Never reuse it — cut out the section or replace the whole rope.
-
Golden rule: never force a jammed traction hoist, and never lift with a loose wire rope.

FAQ
Why does a suspended platform wire rope kink?
When the wire rope goes slack, its stored twist releases and it spins into a loop that locks into a permanent kink.
Can a kinked steel wire rope be reused?
No — replace it, or cut out the section and re-make the rope end.
How do I stop a traction hoist wire rope from jamming?
Keep the rope taut, keep the rope groove clean, and replace worn wire rope on time.
Where can I buy replacement wire rope for a suspended platform?
From a supplier that offers man-riding-grade steel wire rope — like RIGID Machinery.
Final Thoughts
Correct installation, a taut wire rope, and routine maintenance prevent most suspended platform wire rope problems.
