Adjustment & Theory of the SGG 4 Geared Limit Switch on Gen 1 Demag DMR Wire Rope Hoists 

The SGG4 geared limit switch is the standard upper and lower limit switch for hoist travel on many Demag wire rope hoists, including the Generation 1 Demag DMR wire rope hoist with contactor control. In addition to this hoist, the SGG4 has been used on DR Pro, DR COM, DR Bas, DMR SC, Generation 2 DMR, and DC chain hoist models 16 and 25. Watch as Demag Technical Trainer, Andy Rasch, takes you through the adjustment and theory of the SGG4 limit switch for your next service call.
