An automated carting assembly includes a cart that has a plurality of garbage containers each being positioned thereon. The cart has a slidably adjustable length for accommodation a varying number of the garbage containers. A pair of rear wheels is each rotatably coupled to the cart for rolling on a support surface and each of the front wheels is steerable on the cart. A pair of front wheels is each rotatably coupled to the cart for rolling along the support surface. A pair of steering actuators is each coupled to a respective one of the front wheels for steering the cart. A pair of drive motors is each rotatably coupled to a respective one of the front wheels for driving the cart between a storage point and a pickup point.

A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.

Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.
