れ程広く取れない場合には不具合であった。A conventional power unit for a hydraulic elevator will be explained based on FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes a tank for aerobic acid, and a pump 2 driven by a motor 3 is connected to this tank by a pipe 5. A flow rate control valve 4 for controlling pressure oil is connected to this pump, and has a return pipe 6 and a pipe 7 to a gear (not shown). Also, a pump 8 is installed near the power unit to prevent oil temperature from rising, and a radiator 9 is installed on the discharge side of this pump. There is a cooling device consisting of a fan 10 that blows air to the radiator. Although this diagram shows an air-cooled cooling device, the same applies to a water-cooled cooling device. This type of power unit requires a large floor space in the machine room, which is a problem if the machine room cannot be made that large.
最近、この様な欠点を解消するため冷却装置を第２図の

油圧エレベータ−パワーユニットとしては背が高くなる
ため、クーラーの点検が困難となる欠点があった。Recently, attempts have been made to solve this problem by installing a cooling device on top of the tank as shown in Figure 2. However, this system requires a large capacity of the tank, making it difficult to use as a hydraulic elevator power unit. The drawback was that it was difficult to inspect the cooler because of its height.

守点検が容易なパワーユニッＩｆ提供するにある。An object of the present invention is to provide a power unit If in which a cooling device is built into the power unit, the installation area of the power unit is small, and maintenance and inspection of the cooling device is easy.
以下、本発明を第３図に示ず冥施例で説明する。 The present invention will be explained below using an example not shown in FIG.

０がパワーユニットの外側に取シ付けられる。Other than the cooling device, it is the same as a conventional power unit. Further, a pump 8 for the cooling device is installed on a bracket 11 attached to a side plate of the tank 1, and a radiator 9 is connected to the pump through a pipe 12 and installed inside the power unit. In addition, fan 1 that blows air to the radiator
0 is attached to the outside of the power unit.
