Abstract
An apparatus is provided with an outer frame with a series of wheels, and first and second support arms connected to the outer frame and extending upwardly. The apparatus has first and second rails to slidably receive an upper lip of a portable waste receptacle, with the first rail supported by the first support arm for translation relative to the first support arm. The apparatus has a dumping system with a lifting assembly and a power assembly. The dumping system is connected to the outer frame and the first rail to move the first and second rails along the first and second support arms between a load position and a dumping position. A controller is in communication with the dumping system to control the position of the first and second rails via the dumping system.
Claims19
An apparatus comprising:
- an outer frame having an end wall positioned between and connecting first and second side walls, the outer frame having a series of wheels to support the outer frame on an underlying ground surface;
- a first support arm and a second support arm, each support arm connected to the outer frame and extending upwardly from the outer frame to a hooked region, each hooked region extending outwardly from the associated support arm and away from the outer frame to extend over an upper edge of an adjacent waste container;
- a lifting assembly positioned within the outer frame, the lifting assembly having a subframe with a floor, the subframe supporting first and second rails, wherein at least one of the first and second rails is supported by the first and second support arms for translation relative thereto such that the lifting assembly is moveable relative to the first and second support arms between a load position and a dumping position, wherein each of the first and second rails have an upper flange and a lower flange sized to slidably receive an upper lip of a portable waste receptacle therebetween;
- a chain drive system having an upper sprocket and a lower sprocket supported by the first support arm, and a chain in meshed engagement with the upper and lower sprockets, the chain connected to the lifting assembly such that the chain drive system is operable to move the lifting assembly relative to the first support arm;
- a rotary motor with a rotary output shaft drivingly connected to the lower sprocket, the rotary output shaft rotating about a longitudinal axis extending though the rotary output shaft;
- and
- a controller in communication with the motor to control a position of the lifting assembly relative to the chain drive system.

An apparatus comprising:
- an outer frame having an end wall positioned between and connecting first and second side walls, the outer frame having a series of wheels to support the outer frame on an underlying ground surface;
- at least one support arm connected to the outer frame and extending upwardly from the outer frame to a hooked region, the hooked region shaped to extend over an upper edge of a waste container;
- at least one rail positioned adjacent and alongside the outer frame, the at least one rail supported by the at least one support arm for translation relative thereto, wherein the at least one rail has an upper flange and a lower flange that each extend longitudinally along the rail and are fixed relative to one another, the upper flange and the lower flange being spaced apart from one another and sized to slidably receive an upper lip of a portable waste receptacle therebetween, the upper and lower flanges each configured to cooperate with the upper lip of the portable waste receptacle to limit movement of the portable waste receptacle in a direction transverse to the upper and lower flanges;
- a dumping system having a lifting assembly driven by a power assembly, the dumping system connected to the outer frame and the at least one rail to move the rail along the at least one support arm between a load position and a dumping position;
- an alignment member affixed to a distal end of the hooked region;
- a clamping assembly affixed to one of the at least one support arm and the alignment member, the clamping assembly positioned to engage a side wall of the waste container in a deployed position and limit movement of the apparatus relative thereto, wherein the clamping assembly is configured to be in the deployed position as the lifting assembly moves from the load position to the dumping position;
- and
- a controller in communication with the dumping system to control a position of the first and second rails via the dumping system.
