FIELD: transport.

SUBSTANCE: invention relates to excavator drive with set of separate drives such as rotation gear drive, lifting gear drive, bucket drive and handle drive, where for rotary gear drive two reverse adjustable devices are provided which devices are connected with at least one energy accumulator. Invention task consists in excavator drive improvement so that as large as possible portion of driving energy could be recovered and put at disposal for other drive motions. The excavator drive consists of a number of separate drives such as rotation gear drive, lifting gear drive, bucket drive and handle drive, lifting gear drive, bucket drive and handle drive. In this structure, two reverse adjustable devices are provided for as rotation gear drive which devices are connected with at least one energy accumulator. One of reverse adjustable devices is made capable to be connected with excavator driving gear. In this structure, reverse adjustable devices represent hydraulic adjustable devices, and adjustable devices of rotary gear drive are energetically connected with adjustable devices of lifting gear drive.
