An elevator car arrangement includes an elevator car body including a roof, a bottom and side walls, and an elevator car sling for being guided along vertically extending guide rails. The elevator car sling includes at least a first vertical side support, a second vertical side support and an upper horizontal support, which supports are connected to each other to form the sling. The elevator car body is connected to the elevator car sling such that the elevator car body is supported in the elevator car sling. The elevator car arrangement further includes a connection element for connecting the elevator car body to the elevator car sling such that the connection element is arranged between the roof of the elevator car body and the vertical side support of the elevator car sling, the connection element including a damper for damping vibrations caused by guide rails. A connection element for connecting an elevator car body to an elevator car sling is provided to form the elevator car arrangement.

Elevator car arrangement and a connection element

A method for balancing an elevator car including a frame; a cabin box mounted on the frame; and a plurality of elastic members, such as springs, in vertical direction between the frame and the cabin box, via which elastic members the cabin box rests on the frame. The method includes measuring the vertical distance between the frame and the cabin box in several horizontally spaced apart locations with distance sensors; and adjusting the weight distribution of the cabin box by adding and/or removing weight elements on the cabin box. An arrangement for balancing an elevator car is provided to implement the method.

Method and elevator arrangement

An elevator includes at least one elevator car driving in an elevator shaft driven by an elevator drive. The elevator car has at least one car door and a door sill at the bottom of the car door, which door sill includes at least one groove, in which the car door is guided, in which groove at least one trash hole is located to prevent trash from accumulating in the groove, whereby the elevator car further includes a toe guard which extends downwards from the door sill. The trash hole is connected with a first upper end of an air channel extending downwards from the door sill and includes at least one channel portion extending with a direction component in a horizontal direction and/or having an opening directed sideward, which air channel is connected with the toe guard. The elevator leads to a reduced noise generation in the region of the door sill, particularly in elevator cars traveling with a high speed.

Gliding means are attached to a side frame of the car sling, said gliding means comprising a gliding part supported through elasticity means on a frame part. The side frame is positioned on a guide rail in an elevator shaft so that the gliding part of the gliding means sets on the guide rail. The gliding means is provided with an installation jig comprising a first branch positioned between the gliding part and the guide rail, and a second branch positioned in an open space between the frame part and the gliding part for bypassing the elasticity means. The installation jig is removed when the installation of the car sling and the car has been completed.
