摘要：PROBLEM TO BE SOLVED: To provide a device for controlling engine start for a hybrid type work machine, which can reach rotation speed within a range allowing the device to be steadily operated, in a short time even under a low temperature.SOLUTION: The device for controlling engine start for a hybrid type work machine comprises: an engine 61; a stator 64; a power generating motor 63 coaxially connected to a crank shaft of the engine 61; a power storage device 65; a key switch 32; a vehicle body controller 34 inputted with a start signal of the key switch 32; outside air temperature determining means 73 that determines an outside temperature in an operation area; first engine starting means that starts the engine 61 by cranking the engine with the power generating motor 63; second engine starting means that starts the engine 61 by cranking the engine with the stator 64; and third engine starting means that starts the engine 61 by cranking the engine using both the stator 64 and the power generating motor 63. The vehicle body controller 34 selects either one of the first to the third engine starting means according to the outside temperature in the operation area determined by the outside temperature determining means.SELECTED DRAWING: Figure 3
