摘要： A control valve block is mounted on a bottom plate of a revolving frame through a control valve block mounting plate. In this case, a left support member and a right support member are provided on a back surface of the control valve block mounting plate at two spots with equal distances sandwiching a center position of gravity (G) of the control valve block. The left and right support members are mounted on a support beam provided on the bottom plate of the revolving frame. On the other hand, a weight-reducing part is provided at a part in the bottom plate of the revolving frame away from the support beam. The control valve block which is a heavy article is stably supported on the bottom plate at two spots sandwiching its center position of gravity (G). Moreover, the weight of the revolving frame can be reduced by the weight-reducing part.

摘要： 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.

摘要： A heat exchanging device has a frame member mounted on a revolving frame, and this frame member supports an oil-cooler and a radiator. A support member is to support a canopy and the like. The support member is composed of a housing support base provided by extending in the left-right direction on an upper side of the engine and a left front leg part and a left rear leg part each having an upper end mounted on a left-side position in the left-right direction of the housing support base and a lower end mounted on the revolving frame by straddling an engine. The housing support base of this support member has a right side in the left-right direction formed as a free end. Further, the free end of the housing support base is configured to be mounted on the frame member of the heat exchanging device.
