Claim 11:
12. A mechanical arm system for a refuse vehicle, the mechanical arm system comprising:
a mast comprising a track having a lower portion and an upper portion, the upper portion defining a profile that curves inwardly towards the refuse vehicle;
a grabber configured to grasp a refuse container, the grabber comprising a carriage supporting movable graspers;
a conveyor attached to the carriage of the grabber and supported to move in a closed loop along the mast;
a first electrical actuator configured to drive the movable graspers between an open position and a closed position; and
a second electrical actuator configured to rotate a gear to move the conveyor, wherein the carriage of the grabber is coupled to the mast via the conveyor configured to engage a pinion such that rotation of the pinion drives the carriage of the grabber along the track of the mast between an initial position and a dump position, such that:
with the carriage in the initial position on the lower portion of the track, the grabber holds the refuse container in an upright orientation; and
with the carriage in the dump position on the upper portion of the track, the grabber holds the refuse container in a tilted orientation,

wherein the second electrical actuator is configured to apply force to the conveyor through the gear to drive the carriage of the grabber along the track of the mast.
