The speed control system comprises one or more than one speed control track attached to the elongate guide rail and extending along the axis, a background speed controller coupled to the trolley and engaged with the one or more speed control track when the speed control system or the trolley is in a travelling orientation and controlling the speed of the trolley along the elongate guide rail to not exceeded a maximum walking speed. The speed control system also includes a speed controller coupled to the trolley and engagable with the one or more than one speed control track, the speed controller displaceable from a first position when the speed control system or the trolley is in the travelling orientation, and the speed controller is not engaged with the speed control track, to a second position when the speed control system or the trolley is in a falling orientation and the speed controller is engaged with the speed control track. The speed controller for controlling the speed of the trolley along the guide rail in the falling orientation to not exceed a maximum fall speed.

An oil separator includes a heating device that heats liquid stored in a liquid storage portion, a connecting pipe that connects the liquid storage portion to an external device that utilizes oil, an opening/closing device that selectively opens and closes the flow path of the connecting pipe, and a determination device that determines whether the liquid stored in the liquid storage portion should be delivered to the external device. The opening/closing device is configured to open the flow path of the connecting pipe when the determination device determines that the liquid accumulated in the liquid storage portion should be delivered to the external device.
