US 6,167,795 A · Container box and lifter features

Abstract

A refuse collection truck may be combined with a relatively larger refuse container having a cart lifting apparatus supported on such container. The truck has dump arms for selectively dumping the larger container. The cart lifting apparatus has a dumper actuator for lifting and dumping the contents of a residential refuse collection cart into the relatively larger refuse container. The container may be removably mounted on the collection truck through corresponding matable lift forks on the truck and fork channels on the container. The container preferably may be a front end load container box. Different forms of cart lifters may be used, for picking up different styles of collection carts, such as having either one or two lift pickup points (i.e., either European or domestic style carts). Different types of dumper actuator may be used, including either hydraulic or pneumatic systems, and including either rotary motors or lifting cylinder and piston combinations.

Dependent claims

A refuse collection truck, having a hopper for the receipt of refuse therein, and having dump arms for dumping the contents of a container into said hopper, a relatively larger refuse container associated with said dump arms for being dumped thereby, and a cart lifting apparatus supported on said relatively larger refuse container and having a dumper actuator for lifting and dumping into said relatively larger refuse container the contents of a residential refuse collection cart.

Improved refuse collection combination, configured for alternative usages for either residential or commercial collection duties, said combination comprising:

a refuse collection vehicle, having a generally open upper refuse hopper for receipt of refuse into said vehicle, and having dump arms for dumping the contents of a commercial container into said vehicle refuse hopper;
a front end load container box comprising a relatively larger commercial refuse container removably received on said vehicle dump arms for having any contents thereof dumped into said vehicle refuse hopper;
a cart lifting apparatus mounted on said front end load container box and having a hydraulically driven dumper actuator for controllably lifting and dumping into said front end load container box the contents of a residential refuse collection cart;
and
a controllable hydraulic drive system for operation of said cart lifting apparatus, including a source of hydraulic power carried by said truck, a hydraulic drive circuit supported by said front end load container box and operatively interconnectable between said source of hydraulic power and said hydraulically driven dumper actuator, and removable interconnections between said hydraulic drive circuit and said source of hydraulic power, such that said front end load container box, said hydraulic drive circuit, and said cart lifting apparatus may be alternately engaged and disengaged with said refuse collection vehicle for selected use therewith.
