Maintenance supports

folding, for a temporary protected space in the pit

Maintenance supports


The folding maintenance support is ideal for creating a temporary protected space in the pit. During normal operation the support lies on the floor. With a height of only 14cm it can be mounted in very small pits.
When entering the pit for maintenance or other works, the support has to be folded up. The support automatically locks into place when it reaches a vertical position. To fold it again, the locking bolt has to be released.
Both positions of the maintenance support are monitored by a safety switch with forced disconnection. The length of the support can be adjusted. Optionally a lift buffer can be mounted.
Maximum static load: 2000kg per support.
Maximum velocity: 1m/s
