Abstract: Example embodiments relate to an elevator car, including a car spoiler at its top and/or bottom thereof, a car sling with a horizontal frame part on which at least one elevator cabin is supported, and at least one vertically extending spoiler element is located aside of the horizontal frame part. The spoiler element may have upper and lower flange portions, at least one of the upper and lower flanges being connected with elevator car parts located above and/or below of the frame part, and a vertically extending middle portion. The spoiler element may be arranged a distance from the frame part. An elevator car having this arrangement may reduce noise and provide better efficiency.

Abstract: 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.

Abstract: An elevator includes a car and a counterweight suspended on hoisting ropes which are driven by a drive machine. The counterweight has a first side facing the elevator car path and a second side opposite to the car path. The counterweight includes at least one connecting passage between the first and second side of the counterweight. With this solution, air pressure built between the car and the counterweight when passing in the elevator shaft is reduced and the travel comfort is improved.

Abstract: 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.

Abstract: 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.

Abstract: Loose joints and other defects, such as manufacturing, installation, wearing and other similar defects, are hard to find. Especially in case of passenger elevator it is crucial to find these defects in order to produce safe elevators. Testing can be done using a special test signal that is formed by combining an excitement signal with movement control signal. The test signal causes purposively pulsating or oscillating movement of the elevator car that deviates from the ordinary movement of the elevator. This movement causes noises from loose joints and other defects. The sources of these noises can then be located and the defects can be fixed.
