Snöslunga med kopplingar som utlöses av överbelastning

摘要

The snow plow incorporates safety clutches, comprising of a spring-loaded hollow shaft (5) of a feeder worm (4), a coupling ring (3) on the worm, and a counter ring (1) on the drive shaft (16). All parts act together during overloads, to interrupt the power flux to the feeder worm. The worm has 2 - 8, pref. 4 - 6 rotating feeder blades (8).
