  • the mounting positions of the movable member operating unit 35 and the mechanism unit (36, 37, 39-42, 55) mounted on the substrate unit 40 relative to the crosshead 50 are adjusted in three mutually perpendicular directions by the long holes 103a, 103b, and 103c through which the bolts 104a, 104b, and 104c pass, respectively.
  • the third bracket 130 is fixedly connected to the second bracket 102 by the bolt 108 while abutting against the corner of the first bracket 101.
  • the electric actuator of Example 3 is assembled at the manufacturing site, attached to the crosshead 50, and then disassembled into multiple parts (three in FIG. 5) as shown in FIG. 12, using the means described below.
  • the bolt 104b is released from the first bracket 101 to separate the first bracket 101 and the second bracket 102. At this time, the first bracket 101 is held fixed to the crosshead 50 by the bolt 104c.
  • the third bracket 130 is held fixed to the second bracket 102 by the bolt 108.
  • the board section 40 to which the movable member operating section 35 and the mechanism section (36, 37, 39-42, 55) are attached, is held fixed to the second bracket 102 by the bolt 104a.
  • the bolt 104b is screwed into the first bracket 101.
  • the bolt 104b may be passed through a hole in the first bracket 101 and screwed into a nut.
  • the bolt 104b may also be transported to the installation site in a state where it is removed from the first bracket 101 and the second bracket 102.
  • the movable member 34 is removed from the operating lever 11. However, if damage to the movable member 34 and the operating lever 11 can be reliably prevented during transportation from the manufacturing site to the installation site, the movable member 34 may remain attached to the operating lever 11.
  • the electric actuator is disassembled into the following first to third parts, as shown in Figure 12.
  • the first part is the first bracket 101, which is fixed to the crosshead 50 by the bolt 104c.
  • the operating lever 11 is rotatably attached to the operating shaft 19, which is fixed to the crosshead 50.
  • the second part is the second bracket 102 and the third bracket 130, which are fixed to each other by the bolt 108.
  • the base plate part 40 is fixed to the second bracket 102 by the bolt 104a.
  • the third part is the mover 34.
  • the first to third parts described above are brought to the installation site, and the electric actuator is assembled. At this time, the movable member 34 is attached to the operating lever 11, and the first bracket 101 in the first part is connected to the second bracket 102 in the second part by the bolt 104b while the corner of the first bracket 101 is abutted against the third bracket 130.
  • the first bracket 101 and the second bracket 102 are aligned with each other by the shoulder rest of the third bracket 130.
  • the state when assembled at the manufacturing site is reproduced, that is, the state in which the mover operating part 35 is positioned relative to the mover 34 attached to the crosshead 50.
  • the present invention is not limited to the above-mentioned Examples 1 to 3, but includes various modified examples.
  • the above-mentioned Examples 1 to 3 have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to having all of the configurations described.
  • the drive mechanism (11-20) and electric actuator 10 of the safety device in Examples 1 and 3 may be provided on the lower or side of the car, in addition to the upper part.
  • the drive mechanism and electric actuator are provided on the structural members of the car as appropriate.
  • the drive mechanism (11-20) and electric actuator 10 are installed below the crosshead 50. This allows the drive mechanism (11-20) and electric actuator 10 to be provided on the car without increasing the overhead dimensions.
  • the elevator system may have a machine room in which the hoist and control panel are installed, or it may be a so-called machine room-less elevator.
