The present invention relates to an engine power mechanical test apparatus. The engine power mechanical testing apparatus of the present invention is configured such that when the engine power machine is coupled and rotated, the pump is operated to supply the working fluid to the pressure control valve, thereby determining the operation state of the pressure control valve, And more particularly, to an engine-powered machine test apparatus capable of measuring the engine power.

Generally, when working in a place where power supply is not easy, such as outdoors, an engine powered machine is used, which generates a rotational force by driving the engine because a power transmission mechanism can not be used.

These engine-powered machines are often applied to air vents used in maintenance or replacement of train rails. Train rails are installed over long distances and are often used because the location of damage is unreliable and must be able to move quickly for emergency repairs when damage occurs.

An air conduit used for maintenance or replacement of a train rail using an engine powered machine is a high speed cutter that requires high speeds of rotation and power to cut the rail, And an impact that requires a large amount of force to tighten the bolts.

When these engine power machines are used, a fault occurs and the fault is repaired and distributed to the field again.

It is important that the engine revolutions and power output after engine failure are repaired. This is because in case of an emergency, emergency recovery work is delayed if the normal number of revolutions and power do not come out when using the engine power machine.

Conventionally, the engine power machinery has relied on the sense of the human being to determine whether the normal rotation speed and force are output. Therefore, there has been a need for a test apparatus capable of measuring the rotational speed and the power output of the engine power machine.
