  • reference numeral 17 is a drive unit with which one of the direction-change-pulleys 5 is replaced. In this connection, this replacement can be applied to any of Embodiments 1 to 4.
  • the present invention provides an elevator apparatus comprising: a cage elevating in an elevating path; a counterweight moving in an opposite direction to the cage; a guide rail for the cage to restrict a movement of the cage in the horizontal direction; a guide rail for the counterweight to restrict a movement of the counterweight in the horizontal direction; a rope for suspending the cage and counterweight; a traction machine, round which the rope is wound, for elevating the cage and counterweight via the rope in the elevating path, the traction machine being formed into a thin type, the traction machine being arranged in parallel with one wall face in the horizontal cross-section of the elevating path at an upper position of the floor face of the cage when the cage stops at the lowermost floor of the elevating path and at a lower position of the ceiling of the cage when the cage stops at the uppermost floor; and a direction-change-pulley arranged obliquely with respect to the wall face at an upper position of the ceiling of the cage when the cage stops at the uppermost floor in the elevating path.
  • an area occupied by the traction machine on a projection face of a horizontal cross-section of the elevating path is small, so that an unused space with respect to the entire height of the elevating path can be reduced. Since an entering angle at which the rope enters the rope groove of the sheave of the traction machine is small, the rope can be prevented from being damaged.
  • At least one of the traction machine and the direction-change-pulley is fixed to a beam supported by the guide rail for the cage or the guide rail for the counterweight. Therefore, an upward force caused by rope tension acting on the traction machine and a downward force acting on the direction-change-pulley are canceled to each other in the guide rails. Therefore, a force given to a building can be reduced.
  • a lower end of the traction machine is arranged at an upper position of the floor face of the cage when the cage stops at the lowermost floor in the elevating path. Therefore, even if the pit is covered with water, there is no possibility that the traction machine is damaged.
  • a lower end of the traction machine is arranged at an upper position of the first floor face. Therefore, even if the pit is covered with water, there is no possibility that the traction machine is damaged.
  • the traction machine is arranged at an upper position of the reference floor face. Therefore, inspection work can be easily conducted according to operation of the elevator.
  • the traction machine is arranged at an upper position of the uppermost floor face. Therefore, positional adjustment of the direction-change-pulley and the traction machine can be easily conducted, and inspection can be conveniently performed.
  • the traction machine is attached to a beam for supporting the direction-change-pulley from the lower side. Therefore, forces acting on the guide rails can be reduced. Therefore, positional adjustment of the direction-change-pulley and the traction machine can be easily conducted, and inspection can be conveniently performed.
  • the traction machine is attached to a beam for supporting the direction-change-pulley from the lower side, and the beam has a vibration proof structure. Therefore, vibration of the traction machine and the direction-changepulleys can be effectively insulated.
  • At least a portion of the traction machine and a portion of the direction-change-pulley are arranged being put on each other on a projection face of a horizontal cross-section of the elevating path. Therefore, the elevating space can be reduced.
  • a sheave or motor of the traction machine protrudes from the back face of the guide rail to the cage side on a horizontal cross-section of the elevating path. Therefore, the elevating space can be reduced.
  • a control panel for controlling the traction machine is arranged at the substantially same level as that of the traction machine or right above or right below the traction machine close to it. Therefore, the traction machine and the control panel can be easily inspected.
  • a lower end of the control panel is arranged at an upper position of the floor face of the cage in the elevating path when the cage stops at the lowermost floor. Therefore, even if the pit is covered with water, the control panel is not damaged.
  • a lower end of the control panel is arranged at an upper position of the first floor face in the elevating path. Therefore, even if the underground floor is covered with water, the control panel is not damaged.
  • One of the direction-change-pulley is composed of a drive unit. Therefore, this structure can be applied to an elevator of a large capacity.
  • An inclination angle of the direction-change-pulley with respect to the wall face of the elevating path is made variable or a distance between the direction-change-pulleys on a horizontal cross-section of the elevating path is made variable. Therefore, the same design can be applied even if the cage size is different.
  • the elevator apparatus of the present invention is suitably applied to an elevator apparatus comprising: a cage elevating in an elevating path; a counterweight moving in an opposite direction to the cage; a guide rail for the cage to restrict a movement of the cage in the horizontal direction; a guide rail for the counterweight to restrict a movement of the counterweight in the horizontal direction; a rope for suspending the cage and counterweight; a traction machine, round which the rope is wound, for elevating the cage and counterweight via the rope in the elevating path, the traction machine being formed into a thin type, the traction machine being arranged in parallel with one wall face in the horizontal cross-section of the elevating path at an upper position of the floor face of the cage when the cage stops at the lowermost floor of the elevating path and at a lower position of the ceiling of the cage when the cage stops at the uppermost floor; and a direction-change-pulley arranged obliquely with respect to the wall face at an upper position of the traction machine.
