An elevator car includes a first floor for delimiting a transport space above it, and a second floor for delimiting a second transport space above it. One of the first and second floors is a displaceable floor, the elevator car being shiftable between a double-decker-state and a single decker-state by displacing the displaceable floor. A construction-time elevator arrangement and a method for elevator use during construction of a building, which implement the elevator car, are also disclosed.

Elevator car and construction-time elevator arrangement and method

An elevator arrangement having an elevator includes an elevator car having a floor and a roof. The elevator car is provided with one or more extension spaces which are arranged to extend the height of the elevator car during construction time use.

Elevator arrangement

A rope load detecting device for detecting total rope load in multiple elevator ropes, includes a frame held on the multiple elevator ropes, and a force sensing element. The frame includes a tension beam, a first and second connecting bars, a movable member and a supporting beam, one end of the first and second connecting bars is fixed to the tension beam, the other end is fixed to the supporting beam, one end of the movable member is connected to the tension beam, the other end freely passes the supporting beam. The frame is configured to enable the part of each elevator rope passing through the first and second connecting bars and the movable member of the frame to be bent so that enable the force caused by each loaded elevator rope to act on the force sensing element by means of the movable member of the frame, whereby the total rope load in multiple elevator ropes can be detected by a single force sensing element.

Rope load detecting device for detecting the total rope load in multiple elevator ropes

An elevator may include: drive machine, hoisting ropes, traction sheave, elevator car, counterweight, and elevator car and counterweight guide rails. The drive machine may engage the hoisting ropes using the traction sheave. The hoisting ropes may support the elevator car on the elevator car guide rails and the counterweight on the counterweight guide rails. The hoisting ropes may include coated hoisting ropes of substantially circular cross-section. The hoisting ropes may have a load-bearing part twisted from steel wires of circular, non-circular, or circular and non-circular cross-section. A cross-sectional area of the steel wires may be less than about 0.2 mm. A strength of the steel wires may be greater than about 2000 N/mm. A core of each hoisting rope may include the load-bearing part. The core may be coated with a substantially thin sheath that forms a surface of the hoisting rope. The sheath may be softer than the core.

Elevator provided with a coated hoisting rope

The present invention provides a truss device for an escalator or moving walk comprising an outer panel and an inner panel facing the outer panel, characterized in that, the inner panel is formed from a single integral panel and comprises a body part and a plurality of connection parts extending from the body part toward the outer panel thus forming corresponding through openings in the inner panel, each connection part is connected to the outer panel so that the outer panel and the inner panel are fixed together, wherein the inner panel further comprises a support part formed on the body part of the inner panel and projecting in a direction away from the outer panel. The present invention also provides an escalator or moving walk having the above truss device.

Truss device and an escalator or moving walk

In the invention a method is presented for ensuring operating safety in an elevator system, an elevator system, and a safety device of an elevator system. The elevator system includes at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake is engaged at the end of an elevator run, and the other holding brakes are engaged with a delay. When one holding brake is engaged, the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, a procedure for preventing a hazardous situation is performed.

Elevator brake management system

Elevator rope arrangement in which the elevator car and counterweight, travelling along guide rails in an elevator shaft, are supported by suspension ropes, which are attached to the top part of the elevator car and passed via at least one diverting pulley to the counterweight. Separate hoisting ropes are attached to the lower part of the elevator car and passed to lower part of the counterweight via at least one diverting pulley. The hoisting rope is a substantially thin rope made of synthetic fiber and having a sheath made of plastic material.
