An automated vehicle-mounted refuse collection system having a loader with a boom assembly having inner and outer pairs of arms attached to the vehicle at spaced-apart locations. A lift assembly is pivotally connected to the upper end of the boom so outward movements of the boom arm will cause the upper and lower ends of the lift to reach or extend away from the vehicle toward a refuse container. Gripping arms are mounted on a carriage reciprocal along the lift assembly. A hydraulic system maintains the gripping arm level during extension and retraction of the boom arms.
