摘要

A hydraulic shovel (1) comprises a wireless authentication starting device (37) that switches between conducting and not conducting between a battery (18) and a starter motor (16) or a first electrical component (24) on the basis of the operation of a power switch (12) provided near an operator seat (9) and the wireless authentication of a mobile key (38). When the mobile key (38) is within a range to be authenticated, a gate lock lever (13) is in a lock released position, and the power switch (12) is operated, the wireless authentication starting device (37) switches from "engine stopped and power off" to "engine stopped and power on" when the "engine is stopped and power is off" .
