CONSTRUCTION MACHINE AND PROGRAM REWRITING SYSTEM PROVIDED WITH SAME
An object of the present invention is to minimize processing power required for a controller. A hydraulic shovel (1) includes a control device (12) having a vehicle controller (21) for storing a program and configured to execute rewriting processing of rewriting the program by an update program, and a communication controller (20) communicative with a server (11) having the update program via a communication means (50) and configured to store the update program received from the server (11); and a rewriting determination part (21e) for detecting whether or not the hydraulic shovel is in an electric power supply state in which electric power is supplied to an electrical component. The control device (12) starts transfer of the update program from the communication controller (20) to the vehicle controller (21) when the rewriting determination part (21e) detects that the hydraulic shovel is not in an electric power supply state, and suspends transfer of the update program when the rewriting determination part (21e) detects that the hydraulic shovel is in an electric power supply state after the transfer is started and before the transfer is completed.
