Abstract
A lower travel body that supports an upper unit includes: a center frame that supports the upper unit; a side frame that is provided on both of right and left sides of the center frame to support a travel motor and constitutes a crawler-type travel section; and a plurality of hydraulic hoses, one end side of each of which is connected to a swivel joint provided to the center frame, and the other end side of each of which is connected to the travel motor. The center frame includes: a rear wall having a guide hole, through which the plurality of hydraulic hoses passes; and a hose guide that is located below the guide hole, located above the hydraulic hoses, and thereby restricts upward movement of the hydraulic hoses.
Claims7
A construction machine comprising:
- an upper unit;
- and
- a lower travel body that supports the upper unit, wherein
- the lower travel body has:
- a center frame that supports the upper unit;
- a side frame that is provided on both of right and left sides of the center frame to support a travel motor and constitutes a crawler-type travel section, around which a crawler track is wound via plural rolling bodies;
- a plurality of hydraulic hoses, one end side of each of which is connected to a swivel joint provided to the center frame, and the other end side of each of which is connected to the travel motor, wherein the center frame includes a wall having an opening, through which the hydraulic hose passes;
- a hose guide that is located below the opening, and located over and above the hydraulic hoses, and restricts upward movement of the hydraulic hoses above the center frame and
- a rear surface of the center frame, the rear surface being displaced below from the wall and projected downwardly below the wall, and the hydraulic hose passing bare and exposed between the hose guide and the rear surface.
A construction machine comprising:
- an upper unit;
- and
- a lower travel body that supports the upper unit, wherein
- the lower travel body has:
- a center frame that supports the upper unit;
- a side frame that is provided on both of right and left sides of the center frame to support a travel motor and constitutes a crawler-type travel section, around which a crawler track is wound via plural rolling bodies;
- a plurality of hydraulic hoses, one end side of each of which is connected to a swivel joint provided to the center frame, and the other end side of each of which is connected to the travel motor, wherein the center frame includes a wall having an opening, through which the hydraulic hose passes;
- and
- a hose guide that is located below the opening, and located over and above the hydraulic hoses, such that a height position of an upper edge of the hose guide is a lower position than an upper edge of the opening to restrict upward movement of the hydraulic hoses above the center frame and
- a rear surface of the center frame, the rear surface being displaced below from the wall and projected downwardly below the wall, and the hydraulic hose passing bare and exposed between the hose guide and the rear surface.
