    摘要： A walk behind self-propelled crawler snowplow includes a snowplow mechanism driven by an engine via a belt drive power transmission mechanism (109), and an overload protection device (130) associated with the belt drive power transmission mechanism for protecting the engine against overload. The overload protection device comprises a tension sensor for detecting the tension in an endless belt (103) and generating an electric overload signal to disengage an electromagnetic clutch (101) in the belt drive power transmission mechanism when a belt tension greater than a predetermined value is detected.

    摘要： An overload protecting device (60) assembled in an auger transmission (18) is disclosed as including a worm wheel (38) having its side wall formed with a plurality of wheel-side protruding segments (64), a boss member (41) engaging with the wheel and fixedly coupled to an auger shaft (22) for non-rotating relationship, and a slide washer (45) having a plurality of wheel-side projections (67) facing the wheel-side protruding segments. When the auger shaft encounters a torque exceeding a given value, the worm wheel and the boss member are enabled to rotate relative to one another. As the wheel-side projections ride on the protruding segments, the slide washer is moved in a direction opposed to the worm wheel. A washer detection switch (53) detects such a movement to produce a detection signal to forcibly stop the operation of an engine (15).
