It can also be used to push or pull and transfer, and it is also equipped with a hydraulic cylinder that lifts the load by being operated by hydraulic pressure from the hydraulic tank. There is an effect that can also be used for such purposes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the power pack apparatus according to the present invention includes a main body 100 having a wheel 100a moving along a loadout rail, a fuel tank 100b, and a hydraulic tank 100c; An engine 200 installed in the main body 100 and driven to receive fuel from the fuel tank 100b; A hydraulic pump 300 engaged with the engine 200 to increase the pressure of the hydraulic tank 100c; A drive motor 400 operated by hydraulic pressure from the hydraulic tank 100c to drive the wheel 100a; A hydraulic cylinder 500 operated by the hydraulic pressure from the hydraulic tank 100c to lift the load; A first solenoid valve 610 for controlling the hydraulic pressure supply from the hydraulic tank 100c to the drive motor 400; A second solenoid valve 620 for controlling hydraulic pressure from the hydraulic tank 100c to the hydraulic cylinder 500; A third solenoid valve 630 for controlling the hydraulic pressure supply to the external drive / no drive carriage from the hydraulic tank 100c; A fourth solenoid valve 640 for controlling the hydraulic pressure supply for operation from the hydraulic tank 100c to the external drive carriage; It forms a structure including a control unit 700 for controlling the operation of the engine 200 and the first solenoid valve 610 to the fourth solenoid valve 640.

The upper surface of the power pack device main body 100 is a power pack device installed on the load-out rail to easily enter and exit the lower space of the land drying ship, while the land drying vessel is mounted on the support and raised to a predetermined height from the bottom. It is desirable to be as flat as possible.

For reference, both the driving carriage and the non-driving carriage are equipped with a hydraulic cylinder capable of lifting a load, which is a means used to lift a dry land ship, which is already well known and performed, and thus, more detailed description Will be omitted. In addition, the drive carriage is provided with a drive motor, as a means for transporting the lifted land dry ship to the floating dock, which is also already well known and performed, so a detailed description thereof will be omitted.

Referring to the operation of the power pack device according to the present invention.

First, when the engine 200 is operated by operating the control unit 700, the hydraulic pump 300 is forcibly driven by the engine 200 so that the pressure of the hydraulic tank 100c rises to an appropriate pressure.

In this state, when the first solenoid valve 610 is switched from “off” to “on” by operating the control unit 700, the drive motor 400 is driven by the hydraulic pressure supplied from the hydraulic tank 100c. The wheel 100a engaged with the drive motor 400 is interlocked so that the power pack device moves forward or backward along the loadout rail (not shown). When the control unit 700 is operated to switch the first solenoid valve 610 from "on" to "off", the hydraulic supply from the hydraulic tank 100c is cut off and the power pack device is stopped. The first solenoid valve When 610 is turned "off", since the hydraulic line between the hydraulic tank 100c and the drive motor 400 is cut off, the wheel 100a of the power pack apparatus is maintained without a separate brake means.

By operating the control unit 700 to switch the second solenoid valve 610 from "off" to "on", the piston rod of the hydraulic cylinder 500 is projected to the upper portion of the power pack device main body 100 to the piston rod The loaded load (not shown) naturally lifts upwards. In the case of this embodiment, four hydraulic cylinders 500 are installed in the power pack apparatus main body 100, but the number of hydraulic cylinders 500 can be appropriately changed as necessary.
