摘要:
A tension member for a lifting and/or hoisting system includes a core including a plurality of load carrying fibers arranged in a matrix material, and an outer layer secured to the core including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core. A method of forming a tension member for an elevator system includes arranging a plurality of load carrying fibers along a length of the tension member, retaining the plurality of load carrying fibers in a matrix material to define a core, and enclosing the core in an outer layer including a plurality of outer fibers arranged around a perimeter of the core. The outer layer includes one or more outer fibers arranged off-axis relative to the load carrying fibers of the core.

An elevator system includes a stationary structure, a first sheave rotationally supported by the structure, a rope supported by the first sheave, and an elevator car supported by the rope. A vibration damping device of the elevator system is positioned at a first termination of the rope, and is configured to reduce vibration waves in the rope, thereby reducing noise in the elevator car.

An elevator system constructed in accordance to one embodiment of the present disclosure includes an elevator car, a counterweight, a sheave assembly, a suspension rope, a compensation rope, a first optical sensor assembly and a controller. The suspension rope has a first suspension end coupled to the elevator car and a second suspension end coupled to the counterweight. The first compensation rope has a first compensation end coupled to the elevator car and a second compensation end coupled to the counterweight. The first optical sensor assembly can have a first optical sensor pair including a first emitter and a first receiver. The first emitter is configured to emit a first beam to be received by the first receiver. The first optical sensor pair is configured to detect interruption of the first beam by the first compensation rope. The controller controls movement of the elevator car based on the detected interruption.

The invention relates to a method for monitoring elevator equipment. Said elevator equipment includes a car and/or counterweight, two pulleys that are to be installed on the respective ends of an elevator shaft, a linear element passing through the pulleys and on which the car and/or counterweight is mounted, and a drive motor for moving said linear element. The elevator equipment is arranged so that said at least one linear element forms a closed loop with the pulleys and the car and/or counterweight mounted on the linear element. The method includes: (a) receiving (204) a measured value of a parameter representing a drive torque (C'') applied by the motor, (b) estimating (202, 205) at least one value (Q) of a parameter related to the elevator equipment on the basis of the value received in step (a) of the parameter representing the drive torque, and (c) transmitting a signal, produced on the basis of the value estimated in step (b), to a user interface or device for controlling the elevator equipment.
摘要:
An elevator installation and a method of operating the elevator system for temporary transportation of an overload within the elevator installation includes a car and a counterweight interconnected by one or more suspension ropes engaging a traction sheave that is driven by a motor. The traction between the suspension ropes and the traction sheave is enhanced independently of the counterweight for intended overload operation.

Die Erfindung betrifft eine Aufzuganlage mit wenigstens einem in einem Aufzugschacht verfahrbaren Fahrkorb (102), wobei ein Hängekabel (104) vorgesehen ist, welches ein erstes fahrkorbseitiges Ende und ein zweites schachtseitiges Ende aufweist, wobei die Gewichtskraft des Hängekabels (104) wenigstens teilweise in ein an dem Fahrkorb (102) angreifendes Tragmittel (202) oder Ausgleichsmittel (704) eingeleitet wird
摘要:
In order to improve the safety for elevator passengers, a compensating means (11) is guided between an elevator car and a counterweight on the counterweight side by means of a guide device (12) and monitored by means of a monitoring device (13). During normal operation, the compensating means (11) runs from the counterweight as far as the guide device (12) in a first plane (E1) spanned by guide rails (14, 15) of the counterweight. Stretched from a first bracket (16) to the second bracket (17) is a line (13.1), which passes through a second plane (E2) spanned by the compensating means (11) and is arranged above a loop part (11.2). The line (13.1) is secured to the second bracket (17) and spring-mounted on the first bracket (16) in the line longitudinal axis. In the event of a deflection of the line (13.1) caused by the loop part (11 .2), a cam (13.2) is moved in the line longitudinal axis. The moving cam (13.2) actuates a finger (13.3) of an electric switch (13.4), which switches off the elevator drive.
摘要:
Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.
