Engineering machinery

Provided is an engineering machinery, comprising a clamp seat (30), provided with an installation pin (42) in a protruding manner, and a clamp body (31) disposed on the clamp seat (30). The clamp body (31) comprises a pair of clamp materials (32, 33) which clamp a flexible pipe (17) from the diameter direction of the flexible pipe (17), and a combination mechanism which combines the clamp materials (32, 33) under the state of clamping the flexible pipe (17). The clamp materials (32, 33) are respectively provided with a clamping material side pinhole (40) for the installation pin (42) to insert through. The installation pin (42) traverses through the clamping material side pinhole (40) and penetrates the pair of clamp materials (32, 33), and thereby the clamp body (31) is installed on the clamp seat (30) in a state of moving along the direction of a long edge of the installation pin (42). Accordingly, the vibration of a tubing can be inhibited from being transmitted to a framework.
