Hydraulics trace back to a launch system developed for buses around 1988. Lessons learned on the bus were extended to develop a pure hydraulic-series drive system for refuse vehicles in 1991.

First in line was an American La France Condor with Bosch Rexroth's hydraulic drive system. It is a truck version of the company's HRB (for hydrostatic regenerative braking) system for buses.

In a hydraulic direct drive system the hydraulic fluid acts as a spring, much more efficiently absorbing the load variation without transferring the mechanical energy to the motor or pump components.

Tuthill Drive Systems showed its new EZ Trac hydraulic drive system, which it said provides front-wheel drive for on-road trucks that need to go off-road or travel in bad weather. EZ Trac installs ...
