When a rail is installed at a position slightly deviated from the elevator and a new elevator is installed, the car frame is generally newly designed and manufactured as a new product.

  This is because in the standard specification car, the position of the suspension core is fixed by the car frame to which the main rope is connected. This is because the mind and the center of gravity shift, and the car becomes unbalanced, causing vibration.

  However, when a non-standard specification is used as described above, it is costly to newly design and manufacture a car frame each time because common parts cannot be used and the design and manufacturing lead time becomes longer. Cause up.

  On the other hand, even if the position of the existing rails actually deviated slightly when the car was installed, it was necessary to remake the components that make up the car frame or reopen the connection holes for the components on site. It may correspond.

For example, Patent Document 1 discloses a means for solving the problem of newly designing and manufacturing a car frame or recreating a product locally so that the car frame can be centered efficiently. As described in the above, a long hole extending in the horizontal direction is formed in a bracket provided integrally with the vertical frame, and the floor and the lower frame forming the floor portion can be moved relative to the vertical frame. And the position of the connecting portion between the vertical frame and the cab-side member in the horizontal direction by fastening with a bolt so that the vertical frame can be moved with respect to the upper beam through a long hole formed in the plate. It is considered to be configured to be movable.
