SHOVEL AND METHOD FOR DRIVING SHOVEL

摘要

A shovel has a turning hydraulic motor 21, a turn-driving hydraulic circuit for driving the turning hydraulic motor, an assist hydraulic motor 40 connected to an engine 11 and supplied with hydraulic oil discharged from the turn-driving hydraulic circuit, and a controller 30 for controlling the driving of the shovel. The controller 30 detects the load state of the engine and controls the supply of hydraulic oil to the assist hydraulic motor 40 during turn-decelerating on the basis of the detected load state.
