Claim 15:
16. 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 coupled with the mast and configured to grasp a refuse container, the grabber comprising a carriage supporting movable graspers;
an electrically-driven mast actuator configured to move 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;

an extendable boom having a proximal end and a distal end, the proximal end securable to the refuse vehicle, and the distal end securable to at least a portion of the mast at a distal end; and
an electrically-driven extension actuator configured to rotate a pinion of a rack-and-pinion assembly to move the extendable boom between a laterally retracted position and a laterally extended position.
