Frequently Asked Questions

Does this safety gear operate in both travel directions?

The LD.QJ22A is a progressive bi-directional safety-gear design for ascending and descending braking arrangements.

Is the 1.75 m/s option suitable for every configuration?

No. The typical standard selection is up to 1.0 m/s. A special configuration may suit up to 1.75 m/s only when the actuation arrangement, total mass and complete safety-gear selection are matched.

Which guide rails and total mass should be checked?

Compare the 10 mm or 16 mm solid guide-rail option and the complete rail profile. The typical configurable P+Q range is 800–2500 kg, with the exact selection dependent on the ordered friction-load configuration.

Does the photograph define the order quantity?

The image shows a left- and right-hand pair. Confirm the required handedness, quantity and delivery scope when ordering.
