Claim 0:
1. 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;
a flexible driver 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;
a second electrical actuator configured to apply force to the flexible driver to move the flexible driver and drive 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
a third electrical actuator configured to drive the extendable boom between a laterally retracted position and a laterally extended position.
