Abstract

A drive system for a mobile work platform that includes a variable displacement drive pump 14 coupled to an electric motor 13, where the pump 14 is in a closed hydraulic loop 16 with at least one drive motor 15 driving a wheel of the machine. Energy can be recovered from braking, deceleration and downhill locomotion to charge battery 11 via motor 13 and pump 14. The drive system preferably also includes a combined steer/charge pump 19 and an auxiliary pump 18. Preferably pumps 14, 18, 19 are coupled to a common drive shaft driven by motor 13. The drive system is particularly suitable for use with smaller battery-powered mobile work platforms with working heights less than 15 metres. A drive system comprising a steer/charge pump 19 and an auxiliary pump 18 is also independently claimed.
