Abstract
A side loader for a refuse vehicle has a laterally extendable first arm with an upper carriage connected to a gripper to releasably engage refuse containers. A second curved arm has a first position abutting the top end of the first arm so the upper carriage can reciprocate along the first and second arms. The second arm has a second, rotated position which dumps the refuse container into the vehicle. A drive chain connected to the upper carriage passes over a return roller which changes the direction of the chain before it is connected to the vehicle. A lower carriage reciprocates along the lower side of the first arm and holds two oppositely directed, hydraulic pistons. One piston moves the lower carriage relative to the vehicle and the other moves the return roller to alter the effective chain length and move the upper carriage faster than the lower carriage.
