There must be. In the latter case, it is necessary to remove the oil tank after draining the hydraulic oil into the oil tank connected to the upper part of the hydraulic power unit as well as the existing control panel, and then remove the hydraulic power unit frame. Since the work is increased and the non-operating time of the elevator is prolonged, and the machine room in which the hydraulic power unit is installed is generally small, such a work involving the movement of heavy loads places a heavy burden on the operator.

It is an object of the present invention to provide a hydraulic elevator control panel in which a new control panel can be easily connected to an existing hydraulic power unit.

[0005]

In order to achieve the above object, the present invention provides a hydraulic elevator control panel comprising a new control panel mounted on an existing hydraulic power unit having a frame. A mounting spacer is disposed between the hydraulic power units, a connecting portion with the newly installed control panel is provided above the mounting spacer, and the frame of the hydraulic power unit is clamped and fixed below the mounting spacer. A metal fitting is provided.

[0006] In the control panel structure of the hydraulic elevator according to the present invention, as described above, the fixing bracket for holding and fixing the frame of the hydraulic power unit is provided below the mounting spacer disposed between the control panel and the hydraulic power unit. Even if the existing hydraulic power unit is diverted to the new control panel, the frame is clamped and fixed by the fixing bracket without forming a connection hole or the like in the existing hydraulic power unit in accordance with the new control panel on site, unlike the conventional case. Therefore, there is no need to cure the metal powder so that the metal powder does not scatter and the metal powder does not adversely affect peripheral devices, and the connection can be easily performed.
