SIDE LOADING REFUSE COLLECTION SYSTEM
First Claim
1. A cart lifter adapted to be mounted to a refuse container or vehicle, the lifter comprising:
- a mounting base adapted to be mounted adjacent to a loading area of a refuse container or vehicle;
first, second, third and fourth generally elongated support arms, each having first and second ends and being carried by the base, each of the first and second support arms having its first end pivotally associated with the mounting base and its second end pivotally connected to the first end of the third and fourth support arms, respectively, the first and second support arms being pivotally connected with one another at a position intermediate the ends of the first and second support arms;
the support arms being movable with respect to the mounting base between a first position in which the support arms lie generally flat against the mounting base and a second position in which the support arms are angularly disposed relative to the mounting base; and
a lifter base carried at the second ends of the third and fourth support arms adapted for securing a refuse container capturer thereto, wherein the second ends of the third and fourth support arms are pivotally secured to the lifter base such that the lifter base is maintained in a position generally parallel to the mounting base throughout the movement of the support arms between the first and second positions.

Abstract
A cart lifter is provided that is adapted to be mounted to a refuse container or directly to a refuse collection vehicle. A support is provided that is adapted to be pivotally mounted adjacent to the loading area of either the refuse container or the vehicle. First and second support arms are provided that are carried by the pivoting support. The support arms are movable relative to a support frame between a first position in which the support arms are adjacent the refuse container or vehicle and a second position in which the support arms are relatively angularly disposed with their free ends being spaced outwardly away from the support frame. A container capturer is provided for engaging and releasing a smaller refuse collection cart, and the free ends of each of the support arms are adapted to carry the container capturer. Actuators are provided for dumping or inverting the refuse collection cart, to move the support arms between the first position for storage and/or dumping and the second position for capturing or releasing a cart, and for actuating the container capturer so that it can engage and release the refuse collection cart.

5. A container lifter comprising:
-
a drive base; a rotary actuator including a rotary drive shaft carried by the base; a drive arm having first and second ends, the first end being attached to the drive shaft; a lifter base carried at the second end of the drive arm; first and second gripper arms having first and second ends, the first end of each gripper arm being pivotally carried by the lifter base and movable between a first position in which the gripper arms extend in substantially opposed directions and a second position in which the gripper arms extend in substantially the same direction; the drive arm being movable by the actuator between a raised position elevating the lifter base for dumping a receptacle and a lowered position for engaging or releasing a receptacle; the drive arm including an offset portion defining a nesting region for receiving at least one support arm to which the drive base is connected.

6. A gripper arm for a refuse container capturer having a pair of gripper arms, the gripper arm comprising an axially elongated first portion having proximal and distal ends, the first portion being adapted to be pivotally secured to a container lifter at its proximal end;
- and a second tip portion secured to the first portion generally adjacent to the distal end thereof, the second tip portion extending beyond the distal end of the first portion and being axially displaced therefrom.

9. A container lifter comprising:
-
a lifter base; first and second gripper arms having first and second end portions, the first end portion of each gripper arm being pivotally carried by the lifter base and movable between a first position in which the arms extend in substantially opposed directions and a second position in which the arms extend in substantially the same direction; the second end portion of each gripper arm including a first main arm portion having a first termination end and a second arm portion carried by the main arm portion and spaced therefrom and extending in substantially the same direction as the main arm portion to a second termination end beyond the first termination end.

10. A container capturer comprising:
-
a mount; first and second gripper arms having first and second ends, the first end of each gripper arm being pivotally secured to the mount; a face plate secured to the mount for abutting a refuse collection cart; a hydraulic actuator comprising a cylinder and a piston secured to the mount such that the piston moves generally perpendicularly to the face plate; a bracket mounted to the free end of the piston; and a link pivotally connecting each gripper arm to the bracket. - View Dependent Claims (11, 12)

13. A container lifter comprising:
-
a mounting base; first and second gripper arms having first and second ends, the first end of each gripper arm being pivotally carried by the mounting base and movable between a first position in which the arms extend in substantially opposed directions and a second position in which the arms extend in substantially the same direction; a hydraulic actuator carried by the base movable substantially linearly in said direction; a link pivotally connecting each gripper arm to the hydraulic actuator, whereby linear movement of the hydraulic actuator causes movement of the gripper arms between the first and second positions.
