の寿命が延び、漏出等の故障が少なくなる。In the hydraulic power system for a hydraulic elevator constructed as described in Section 2, an oil tank (5) and a cooling device (7) are arranged in parallel on the base (1), L-, and (1a). Therefore, the height of the hydraulic power device is reduced, and it can be easily installed even in a hydraulic elevator machine room with a low ceiling, and the cost for installing a hydraulic elevator can be reduced. Even if the height of the transport path for the hydraulic power device is low, it is possible to transport the hydraulic power device in one piece, and installation costs can be reduced. In addition, since the pump of the circulation system (8) is placed higher than the Vl(a) plane, 1 Japanese Machinery Industry Association Standards JEM-
When using a 1242 coolant pump, etc., pressure is not constantly applied to the pump. Therefore, the life of the pump shaft sealing device is extended, and failures such as leakage are reduced.
