Abstract: An escalator with steps having a tread surface and riser surface has riser brushes arranged at the riser surface. The riser brushes provide a barrier for the gap which is normally present between the tread surface of a first step and the riser surface of an adjacent step. The riser brushes may be mounted to a brush strip which is guided along the riser as the steps transfer between vertical and horizontal travel.

Abstract: An assembly arrangement for a lift construction supports the lift drive at the upper end of both a support column and lift cage and counterweight guide rails, allowing the lift drive load to be transferred to the floor of the lift by each of the supporting members. The support of the lift drive upon the rails may be accomplished through setting screws that allow the load applied to the rails to be adjusted.

Abstract: An elevator installation with an elevator case, an elevator shaft, and a drive unit. The elevator cage is installed in the elevator shaft to be movable and is controllable by the drive unit so that the elevator cage can be stopped in different positions in the elevator shaft. The elevator shaft is equipped with a detecting device which detects whether a person is standing in a critical zone in the elevator shaft or is about to go into this. The detecting device is connected with the drive unit so that the elevator installation can be transferred to a special mode of operation in case a person is standing in the critical zone or is about to go into this. The drive unit includes special control equipment which in the special mode of operation stops the elevator cage before it moves into the critical zone. In that case the detecting device and the special control equipment are designed to be operationally safe in order to prevent movement of the elevator cage into the critical zone.

Abstract: A crimping device has for each crimper an anvil including a conductor anvil provided with a force sensor on which the force that arises in the conductor anvil during the crimping operation acts. The conductor anvil rests on a sensor body which in turn rests on a supporting part of the crimping device. The force sensor measures the force that is required to manufacture the conductor crimp, the quality of the crimped fastening being assessable by reference to the force curve generated by the force sensor.

Abstract: A crimping device has a contact advancer provided with an exchangeable anvil part. A first pulley, a belt and an advancing motor drive a first carriage. A gripper for advancing the contact belt is guided in a direction crosswise to a direction of the first carriage. The distance between the gripper and the first carriage is determined by a second carriage and a roller of the gripper rolling in a fifth linear guide of the second carriage. The distance from the gripper is predetermined by the exchangeable anvil part and depends on the width of the contact belt. The gripper operates independent of the distance between the transport holes and independent of the width of the contact belt. The anvil part including the belt guide is an exchangeable part and only fits one type of crimp contact and is executed crimp-contact specifically.

Abstract: An escalator or moving walkway with a handrail and a handrail entryway has a finger contact protection cover, wherein the finger contact protection cover includes corrugated bristles. The corrugated bristles allow the gap between the handrail and the entryway to be minimized. The bristle construction also provides improved tactile feedback when a user's hand contacts the bristles, allowing the hand to be more quickly removed from the handrail and contact with the bristles, avoiding potential injury.

Abstract: A method and equipment for checking a support device such as used in an elevator installation.
