K-LADDER Winch-Type Platform Step Ladder KS-205W / KB-205W, Platform Height 1.3-2.2m, Wire Winch Adjustment

K-LADDER KS-205W / KB-205W – Winch-Type Platform Step Ladder

The K-LADDER KS-205W (silver) and KB-205W (black) raise and lower the work platform with a winch-driven wire mechanism, so the platform can be set anywhere between 1.3 m and 2.2 m without manual lifting. A six-point active outrigger stabilises the ladder on uneven ground. Height must be adjusted with the operator off the ladder, and the lock confirmed before climbing. Folded height is 1.9 m and the unit weighs about 37 kg.

Active Outrigger – patented one-touch stabilisation

The core technology of the K-LADDER is the Active Outrigger. With a single touch, each of the six outrigger legs drops independently to match the contour of the ground and locks automatically without folding back. This keeps every foot loaded even on sloped, uneven or stepped surfaces – exactly the condition under which ordinary ladders tip over. The operator does not need to shim, level or re-position the ladder by hand.

Guardrail-enclosed work platform

The worker stands on a full work platform (490 x 450 mm, with toe boards) surrounded by a guardrail and a mid guardrail, rather than balancing on a narrow rung. The guardrail height is adjustable: it is kept retracted for storage and transport, pulled up to waist height in use, or set lower where a ceiling would otherwise interfere. Rated load is 150 kg.

Multi-caster mobility

Casters let one worker push the ladder to the next position without lifting it: in transport mode the ladder sits about 15 mm clear of the floor. Pressing the caster levers seats the rubber feet firmly on the ground and lifts the wheels about 3 mm clear, so the ladder cannot roll while it is being climbed.
