To adopt an inclined shaft type hydraulic pump while maintaining work efficiency in the inserting and pulling-out work of a derricking shaft for supporting an attachment.
An output shaft 50 of an engine 11 is disposed in a position lower than the derricking shaft 8. The inclined shaft type hydraulic pump 12 has a pump body 52 disposed with its axis 52a extended along an upward inclined direction toward the front with respect to the axis of the output shaft 50, and generating oil pressure according to the rotation of the output shaft 50, and a supply and discharge pipe 18 extending forward from the pump body 52 and supplying and discharging operating oil to and from the pump body 52. The supply and discharge pipe 18 is provided inclining at the pump body 52 so that its axis 18a is located below the axis 52a of the pump body 52.
