Lift mechanism for lifting refuse containers

A lifting apparatus for use with a refuse vehicle for lifting and dumping refuse containers, said apparatus comprising:

• a frame;
• a movable pan assembly;
• a pair of pivot shafts attached to said frame in generally parallel alignment and in longitudinally spaced relationship on said frame;
• a pair of guide arms pivotally connected at corresponding locations on said frame and said pan assembly;
• a pair of first actuator arms attached at corresponding locations to said first pivot shaft;
• a pair of second actuator arms attached at corresponding locations to said second pivot shaft and connected at corresponding locations to said pan assembly;
• a reciprocating actuator pivotally connected to said frame and said pair of first actuator arms for controllably moving said pair of first actuator arms;
• and
• a connecting arm attached to said pair of first actuator arms and said pair of second actuator arms to provide corresponding movement of said pair of second actuator arms in response to movement of said first pair of actuator arms to move said pan assembly between the receiving position and the dumping position.

A lifting apparatus adapted for use with a refuse vehicle for selectively lifting and dumping refuse carts, said apparatus comprising:

• a frame;
• a pan assembly adapted to engage the refuse cart;
• a guide arm having a first end pivotally connected to said frame and having a second end pivotally connected to said pan assembly;
• retaining means for pivotally fastening said guide arm to said frame and to said pan assembly;
• a first actuator arm connected at a first end to said frame and having a second end;
• a second actuator arm having a first end connected to said frame and having a second end pivotally connected to said pan assembly;
• a reciprocating actuator having a first end pivotally connected to said frame and a second end pivotally connected to said first actuator arm at a location spaced from said first actuator first end;
• and
• a connecting arm having a first end pivotally connected to said second end of said first actuator arm and having a second end pivotally connected to said second actuator arm at a location between said first end and said second end of said second actuator arm, to thereby enable cooperative movement of said second actuator arm in response to movement of said first actuator arm.

A lifting apparatus for use with a refuse vehicle for selectively lifting and dumping refuse carts, said apparatus comprising:

• a frame mounted to the refuse vehicle;
• a pair of laterally spaced slide bars slidably mounted on said frame for raising said frame;
• a movable pan assembly;
• a pair of pivot shafts attached to said frame in generally parallel alignment and in longitudinally spaced relation on said frame;
• a pair of guide arms pivotally connected at corresponding locations on said frame and said pan assembly;
• a pair of first actuator arms attached at corresponding locations to said first pivot shaft;
• a pair of second actuator arms attached at corresponding locations to said second pivot shaft and connected at corresponding locations to said pan assembly;
• a reciprocating actuator pivotally connected to said frame and said pair of first actuator arms for controllably moving said pair of first actuator arms;
• and
• a connecting arm attached to said pair of first actuator arms and said pair of second actuator arms to provide corresponding movement of said pair of second actuator arms in response to movement of said first pair of actuator arms to move said pan assembly between the receiving position and the dumping position.

A lifting apparatus adapted for use with a refuse vehicle for selectively lifting and dumping refuse carts in response to movement through a complete cycle of a reciprocating actuator, said apparatus comprising:

• a frame;
• a pan assembly adapted to engage the cart;
• a guide arm connected to said frame and to said pan assembly;
• a first actuator arm connected to said frame and to the reciprocating actuator;
• a second actuator arm connected to said frame and said pan assembly;
• and
• a connecting arm connected to said first actuator arm and said second actuator arm, to thereby enable cooperative movement of said second actuator arm and said first actuator arm in response to reciprocating movement of the actuator.
