  • the engineer does not need to move, from the top of the passenger car, to another position where maintenance of the control panel is to be performed and can perform easy, efficient operation.
  • the invention is also directed to the improved elevator system, wherein the control panel is supported by a guide rail or a wall surface.
  • the engineer does not need to move, from the top of the passenger car, to another position where maintenance of the control panel is to be performed and can perform easy, efficient operation.
  • the invention is also directed to the improved elevator system, wherein the lower end of the control panel is arranged so as to be aligned substantially with the upper surface of the car when the engineer has moved the passenger car to a location where the engineer can easily get on the upper section of the car from the platform.
  • the engineer can ride on the upper section of the passenger car and perform maintenance and inspection on the control panel from that position without fail.
  • the invention is also directed to the improved elevator system, wherein the lower end of the maintenance area of the control panel is arranged so as to come to an elevated position above the upper surface of the upper section when the engineer has moved the passenger car to the location where the engineer can have easily ride the upper section of the car from the platform.
  • the engineer can get on the upper section of the passenger car and perform maintenance and inspection on the control panel from that position without fail.
  • Fig. 1 is a schematic view showing an elevator system according to a first embodiment of the invention.
  • reference numeral 1 designates a hoistway surrounded by wall surfaces 8, and a passenger car 2 carrying passengers is caused to ascend or descend within the hoistway 1.
  • Reference numeral 3 designates a guide rail which is engaged with the passenger car 2, to thereby guide ascending and descending action of the passenger car 2.
  • An unillustrated counterweight guide rail is engaged with an unillustrated counterweight, to thereby guide ascending and descending operations of the counterweight.
  • Reference numeral 4 designates a hoist rope which tows the passenger car 2 and the counterweight by way of an unillustrated hoisting machine.
  • the hoisting machine is disposed at the highest position within the hoistway 1 and supported by the guide rail 3 or an unillustrated counterweight guide rail.
  • the hoisting machine is activated under control of a control panel to be described later, whereby the passenger car 2 is caused to ascend and descend within the hoistway 1.
  • Reference numeral 5 designates a control panel which is electrically connected to the hoisting machine or the like by means of a harness and which controls the ascending and descending speeds of the passenger car 2 and timings thereof.
  • the control panel 5 is supported on the guide rail 3 by means of a support section 3a so as not to cause interference with the passenger car 2.
  • the control panel 5 is supported by the guide rail 3 such that a lower end 5a of the control panel is made flush with a platform 6 (e.g., at the highest floor), which is disposed at one of a plurality of floors for use by passengers.
  • the passenger car 2 has an upper section 2a, and a service engineer 7a, 7b can ride on the upper section 2a from the previously-described platform for use by passengers.
  • the engineer 7a, 7b first moves the passenger car 2 such that the upper section 2a of the car 2 is brought into substantially alignment with the height of the predetermined platform 6.
  • the passenger car 2 can be moved by means of activating forceful passenger car movement means which can be operated from outside the hoistway.
  • the passenger car 2 is moved by means of releasing a brake of the hoisting machine.
  • the engineer 7a, 7b rides on the upper section 2a of the passenger car 2 from the platform 6.
  • the control panel 5 is disposed such that the lower end 5a of the control panel is substantially aligned with the position of the upper section 2a.
