The spacers for vacuum pad lifting unit B18DM4(GS) enable the vacuum pad lifting unit to lift window elements with sash bars or casement elements. The distance between suction surface and lifter body is increased by approx. 50 mm.
Due to changed lever ratios, the maximum lifting capacity of the lifting system is reduced to 150 kg. If you use this lifting system in conjunction with a Liftmaster B1 (BO 88.01), the maximum lifting capacity of the entire system is reduced to 150 kg. 4 spacers are included in the scope of delivery.
For the manual Bohle lifting unit BO B18DM4(GS)
Application note:
The spacer must be mounted by Bohle! In case of self-assembly, the UVV test is no longer valid!
