- (o) the lower clamp being mounted on a movable plate;
- (p) a positioning means for the movable plate;
- (q) a secondary support means including a first arm and a second arm;
- (r) the frame including an upper support member supporting the upper clamp and connecting the first side to the second side;
- (s) the frame including a lower support member being oppositely disposed from the upper support member and supporting the lower clamp and connecting the first side to the second side;
- (t) the positioning means including a cam switch;
- (u) the cam switch being adjacent to the lower support member;
- (v) a support arm secured to the frame capable of contacting the cam switch upon movement of the frame;
- (w) the plate extending as the residential container is lifted and retracted as it lowered;
- (x) the plate serving to lock the lower clamp onto the residential container;
- (y) a plate support cylinder supporting the plate on the frame;
- and
- (z) the secondary support means supporting the plate on the frame.
