KOTI Quick changing system
The SW-system means quick change system (in Dutch: Snel Wissel system). The assembly system with bayonet fitting has been used for over decades on brushes for sweeping machines. This is done because everybody can change the brushes easily on the spot and by themselves.
The system exists out of a SW-plate with a fixed sealing ring and assembly plate. The sealing ring protects the engine from dirt penetration.
The quick change plate is directly assembled to the motor shaft which has bayonet fittings (see picture). The bolts of the gutter brush match the bayonet fittings. If the gutter brush is slipped in to the bayonet fittings and makes a little turn, the gutter brush stays fixed completely. Now there are two hands free which can fasten the bolts.
Advantages of the quick changing system:
No extra intermediary plate.
Changed on the spot, easy to replace.
Only one person needed.
The brushes are used more efficiently because the changing is no longer a problem.
When multiple tasks need to be done on one day (e.g. cleaning and weed removing) the quick changing system enables you to change the brush to your task.
No extra-long and heavy lifting needed.
Time and money saving.
