Abstract

Side-loading refuse vehicles are disclosed including an offset or recessed hopper section having at least one recessed side which accommodates a loading bin or bucket which is moveable between a lowered position and a raised dumping position. Followers attached to the bucket on each end are engaged in candy cane shaped guide channels situated at the front and rear of the hopper. The guide channels are angled away from the base of the hopper and curved into the top of the hopper to guide the bucket in an angled and arcuate path over the sidewall of the hopper which is built to accommodate the bucket. In some embodiments, a bin handler is built in to the bucket or an automated arm is provided for dumping refuse cans or containers directly into the hopper. The refuse vehicles may have side-loading buckets on one or both sides of the vehicle and the vehicles may be single or multiple compartment vehicles. In another aspect of the invention, the vehicles include a removable body which is separable from the hopper section.

Claims

1. An apparatus for collecting refuse comprising:

(a) a truck body having a forward end and an aft end and a maximum width mountable to a truck frame and extending longitudinally therealong and enclosing a material receiving volume;

(b) an offset charging hopper having upward extending sides and a top opening and being mountable to the truck frame forward of said truck body and adapted to receive material through the top opening and charge material into said material receiving volume and wherein at least one side of said charging hopper is an offset side recessed a sufficient amount to accommodate the full width of a loading bucket within a maximum width of said truck body, said loading bucket being generally vertically operable along said offset side;

(c) said loading bucket carried by said charging hopper and having an extended inner wall and an outer wall flanked by a pair of end walls, and the bucket describing a loading compartment for receiving refuse material, said extended inner wall extending above the level of said outer wall, said loading bucket being generally vertically moveable along an initially outward extending path along said offset side of said charging hopper between a lowered position and a raised, at least partially inverted, discharge position; and

(d) wherein said path along which said bucket moves is fixed relative to said loading hopper and includes a pair of spaced forward and aft shaped elongated recesses having lower segments that are outwardly directed each adapted to receive a pair of upper and lower follower members generally vertically spaced with respect to said bucket and being attached to a corresponding forward or aft wall of said bucket, said followers being slightly offset, the upper follower being outside the lower follower such that in cooperation with the outward directed lower segments of said recesses said bucket is initially vertical but tilts toward said offset side of said charging hopper when said followers are in a vertical path, said path further including an arcuate upper dumping portion and wherein said offset followers cooperate to increase the degree of inversion of said bucket at a fully up or discharging position.

2. The apparatus of claim 1 wherein said bucket includes a plurality of loading compartments and wherein said hopper includes a like number of receiving compartments.

3. The apparatus of claim 1 wherein the bucket is of a width such that the recess in the side of said charging hopper places said offset side to correspond with the location of a main longitudinal support member of said truck frame.

4. The apparatus of claim 2 wherein the bucket is of a width such that the recess in the side of said charging hopper is such that said it places said offset side to correspond with the location of a main longitudinal support member of said truck frame.

5. The apparatus of claim 1 wherein the upper portion of said offset side of said hopper facing said bucket is flared.

6. The apparatus of claim 3 wherein the upper portion of said offset side of said hopper facing said bucket is flared.

7. The apparatus of claim 4 wherein the upper portion of said offset side of said hopper facing said bucket is flared.

8. The apparatus of claim 1 wherein said bucket is operated by a rod connected to a cover for said hopper.
