Abstract
The present invention is directed to container lift apparatus for a side loading garbage truck. The apparatus includes mechanism for lifting and rotating a container to dump the garbage therein in the open side hopper of the truck. Also, upper and lower retaining assemblies provide for shocking the garbage container during its rotation so that the garbage may be jarred loose from the container. Stabilizing legs support the side hopper to prevent the truck from tipping during the lifting and dumping of the container.
Claims12
Container lift apparatus for a garbage truck, said truck having a box and means for pivoting a side of said box between open and closed positions, said side in the open position forming a hopper for receiving garbage, said side movable with said pivoting means to the closed position to move said garbage from said hopper to said box, said apparatus comprising:
- an arm;
- means for pivotably attaching said arm to said hopper;
- an hydraulic piston and cylinder assembly having one end attached to said hopper and a second end attached to said arm at a location spaced from the axis of said arm attaching means;
- means for controllably energizing said assembly;
- and
- means, attached to said arm, for holding said container;
- whereby said holding means holds said container as said hydraulic assembly rotates said arm to lift said container and dump garbage from same into said hopper.
Container lift apparatus for a garbage truck, said truck having a box and means for pivoting a side of said box between open and closed positions, said side in the open position forming a hopper for receiving garbage, said side movable with said pivoting means to the closed position to move the garbage from said hopper to said box, said apparatus comprising:
- a pair of spaced-apart arms, said arms having means for holding said container;
- means for pivotably attaching said arms to said hopper;
- means, attached to said arms, for lifting said containers upon rotation of said arms;
- a pair of hydraulic piston and cylinder assemblies each having one end attached to said hopper and a second end attached to one of said arms, said assemblies for powerably rotating said arms thereby lifting said containers;
- means for controllably energizing said assemblies;
- and
- means for stabilizing said hopper when said assemblies lift said container.
Container lift apparatus for a garbage truck, said truck having a box and means for pivoting a side of said box between open and closed positions, said side in the open position forming a hopper for receiving garbage, said side movable with said pivoting means to the closed position to move the garbage from said hopper to said box, said apparatus comprising:
- a pair of spaced-apart arms pivotably attached to said hopper, said arms each having a slot spaced approximately the same distance from the pivotal axis of said arm, said slots for receiving rod members attached to the container;
- means, attached to said arms, for locking the rods of the container in said slots;
- a cross member attached to and extending between said arms for lifting the container on rotation of said arms, said cross member being spaced from said slots, said cross member and said slots lifting the container on rotation of said arms;
- a hook member attached to said cross member, said hook member for catching a protuberance attached to said container when said container slides so that the rods attached thereto move from one end of said slots to the other whereby said hook member prevents said container from falling away from said cross member;
- a pair of hydraulic piston and cylinder assemblies each having one end attached to said hopper and a second end attached to one of said arms at a location spaced from the axis of said arms, said assemblies for powerably rotating said arms thereby lifting said containers;
- means for controllably energizing said assemblies;
- and
- a pair of spaced-apart legs for stabilizing the hopper of said garbage truck when said assemblies lift the garbage container.
