PROBLEM TO BE SOLVED: To make it easy for a user to see driving cessation of an elevator due to over rise of oil temperature. SOLUTION: A display device of this hydraulic elevator detects oil temperature at a proper place of the hydraulic elevator by an oil temperature detection means 24 and informs a building manager and a user that driving of the hydraulic elevator is soon ceased due to rise of oil temperature by lighting a display lamp set at an optional place where a cessation warning display control means 23 is set, for example in a superintendent room or an elevator platform 6 in a specified state, for example, by blinking and in color to show cessation warning at the time when the oil temperature exceeds specified cessation warning temperature. Additionally, when the oil temperature rises further and exceeds specified driving cessation temperature, it informs to the building manager and the user that the hydraulic elevator is in driving cessation due to over rise of the oil temperature in a different state from the state of cessation warning display, for example, by lighting the display lamp 21 by the cessation display control means by continuous lighting and in color showing driving cessation. |
