Heavy duty cart lifter
First Claim
1. A lifting device for lifting and inverting a refuse collection container having a body with spaced-apart upper and lower engagement surfaces, the lifting device comprising:
- a base;
a face plate pivotally mounted with respect to the base for movement between a first, lower position and a second, raised and inverted position;
an actuator mounted to the base and operatively attached to the face plate for moving the face plate between the lower and the raised and inverted positions;
a lift member fixedly mounted to the face plate for engaging the upper engagement surface of a refuse collection container; and
a latch assembly mounted to the face plate for capturing the lower engagement surface on the refuse collection container, the latch assembly further comprising a track carried by the face plate;
a slide movably mounted in the track;
a hook pivotally carried by the slide for movement between a position for capturing the lower engagement surface and a retracted position, the hook being biased toward the capturing position; and
at least one actuator arm having first and second ends, the first end being pivotally carried by the base and the second end being operatively connected to the slide, whereby when the face plate is moved from the raised and inverted position to the lower position, the actuator arm moves the slide along the track to cause the hook to engage a portion of the face plate to move the hook to the retracted position.

Abstract
A cart lifter is disclosed for lifting and inverting a refuse collection cart. The preferred cart lifter comprises a base and preferably has a lift member pivotally mounted with respect to the base for engaging the upper engagement surface of a refuse cart and a hook for capturing the lower engagement surface on the cart. An actuator is mounted to the base and is operatively attached to the lift member and hook for moving them between a lower and a raised and inverted positions. An actuator arm pivotally connects the base to the hook and the hook is mounted for movement between a position for capturing the lower engagement surface of the collection cart and a retracted position.

7. A lifting device for lifting and inverting a refuse collection container having a body with spaced-apart upper and lower engagement surfaces, the lifting device comprising:
-
a base;
a lift member for engaging the upper engagement surface of a refuse collection container;
a hook for capturing the lower engagement surface on the refuse collection container, the hook being pivotally movable between a position for capturing the lower engagement surface and a retracted position, the hook being biased toward the capturing position;
an actuator mounted to the base and operable to move the lift member and hook in unison between a first, lower position and a second raised and inverted position;
at least one actuator arm having first and second ends, the first end being pivotally carried by the base and the second end being operatively connected to the hook, whereby when the lift member and hook are moved from the raised and inverted position to the lower position, the actuator arm moves the hook to the retracted position. - View Dependent Claims (8, 9, 10, 11, 12)
