    摘要: Disclosed therein is an apparatus for fixing hydraulic pipes for a construction machine having a hydraulic pipe clamp fixing a plurality of pipes to a boom structure, including: a lower clamp (20) having a mounting hole (21); a clamp position setting member (22) for fixing the lower clamp (20) to one side of the boom structure (100) through a clamp support member (23) coupled to the mounting hole (21); an upper clamp (30) coupled onto the lower clamp (20) and having an interference prevention groove (31) in which a head portion (23a) of the clamp support member (23) is placed; and vibration-proof members (41,42) attached to the interiors of the clamps (20,30) to absorb vibration of the pipe (10). When the pipes (10) are assembled or disassembled, the lower clamp (20) is fixed to the boom structure to set the positions of the pipe and the clamp, and thus the assembly is greatly improved. Also, the clamp position setting member (22) for the lower clamp (20) is protected by the upper clamp (10) without being exposed to the outside, and is maintained without interfering with the outside.

    摘要: A cooling device (20) mounted on a wheel loader (10) includes a radiator (22), an oil cooler (23), an after-cooler (24), air conditioner condenser (25) and a fuel cooler (26). An opening/closing mechanism (31) for pivoting the oil cooler (23) is configured to pivot the oil cooler (23) to a position at a predetermined opening angle about a pivot shaft (31 a) disposed in the vicinity of the right end of the front surface of the oil cooler (23). The rotary shaft (31a) is disposed while being slanted at an angle α with respect to the vertical direction in the back-and-forth direction of a vehicle body (11).
