Abstract
A compact excavator includes: a swing post which is attached to a upperstructure and which can swing in a left/right direction, a working device which is attached to the swing post and which includes a boom cylinder, a counterweight, and hydraulic hoses which extend upwards between opposite side plates of the swing post, and through which pressure oil for driving the boom cylinder of the working device is guided. The compact excavator further includes a guide plate which is provided in the swing post, and which guides the hydraulic hoses downwards while restricting the hydraulic hoses from moving to approach a handrail when the hydraulic hoses attempt to expand toward the handrail due to driving of the working device.
