摘要:
An elevator has a mechanical linear drive arranged laterally at an elevator shaft head to drive at least one belt that moves a car and a counterweight in the shaft. The belt is fixed in the shaft at opposite ends and extends about a drive wheel of the elevator drive. Deflection rollers of the drive determine the angle of encirclement of the belt on the drive wheel.

An apparatus for moving a car along a travel path along guide rails includes a linear drive having a fixed first platform attached to the car and connected by springs with a movable second platform. Holding-units are attached to both platforms for engaging the guide rails and operating-units are connected between the platforms for relative movement. The holding-units and the operating-units include piezoelectric actuators that are selectively energized to move the car.

An installation, such as an elevator installation, has a belt-like drive apparatus driven by friction couple with a drive pulley. The drive apparatus has at least one electrically conductive element extending in a longitudinal direction of the drive apparatus. During operation of the installation, a contact apparatus contacts the at least one electrically conductive element of the moving drive apparatus for transmission of signals and/or electrical energy.

A cable fixing point for fastening at least one cable includes a cable end fastening for the cable end and a rotary mounting for the cable end fastening, wherein the rotary mounting enables rotation of the cable end fastening about an axis and the axis can be aligned by a tension force acting on the cable. In an elevator for transporting at least one load carrier by at least one cable movable in its longitudinal direction wherein the respective cable at the cable end is disposed under a tension force, the direction of which is variable in dependence on a position of the load carrier, this cable fixing point permits rotation of the cable at the cable fixing point about an axis which is aligned in the respective direction of the tension force and/or in the respective longitudinal direction of a cable segment adjoining the cable fixing point.

A door drive has a drive unit and a belt-like drive for moving at least one door leaf. At least one electrically conductive element extends in a longitudinal direction of the belt-like drive for transmission of electrical signals or energy to/from the at least one door leaf. A first contact device extends into a longitudinal groove formed in the belt-like drive enabling access to the at least one electrically conductive element. When the belt-like drive is moving past the first contact device, the first contact device produces a permanent contact with the at least one electrically conductive element.
摘要:
An elevator installation includes at least one elevator car and at least one counterweight, wherein the at least one elevator car is capable of being moved on guide rails in an elevator shaft by a drive with a driving pulley and with a supporting and propulsion apparatus. The at least one counterweight is formed with a hollow body enclosing a filling. In the event of a freefall, the hollow body is destroyed allowing the filling to emerge.
摘要:
An elevator having a car and a suspension member or respectively hoisting member for carrying an operating weight. Furthermore, a power transmission is intended for moving the suspension member and the hoisting member over at least one moving surface of the power transmission. The power transmission and the suspension member or respectively hoisting member are rope-shaped and/or belt-shaped. Also, the power transmission and the suspension member or respectively hoisting member are physically separated from each other. The power transmission and the suspension member or respectively hoisting member are stretched against at least one supporting body.
