Method for constructing an elevator system having an adaptable usable lifting height
A method for constructing an elevator system in a building includes performing at least one lifting operation to adapt a usable lifting height of the elevator system to an increasing height of the building. A drive platform supporting an elevator drive machine and, by a flexible support, an elevator car and a counterweight is raised during the lifting operation. A difference between an elevator-car-side support weight and a counterweight-side support weight is substantially compensated by a compensating tension device guided from a bottom side of the elevator car to a bottom side of the counterweight by a deflecting device including two roller assemblies having deflecting rollers forming a compensating tension loop. A distance between the roller assemblies is reduced before and/or during the lifting operation such that an amount of the compensating tension device required for the performance of the lifting operation is released from the compensating tension loop.
METHOD FOR ROPING AN ELEVATOR
A method for roping an elevator. At the bottom part of the elevator shaft the hoisting ropes are routed under the pulleys of the elevator car. Then the elevator car and the counterweight are hoisted to the upper part of the shaft where the first ends of the hoisting ropes are routed through the traction sheave and the counterweight pulleys. After that the first rope ends are fixed to the counterweight side rope terminals and the counterweight is lowered to the bottom part of the shaft. During the descent the hoisting ropes are unwound from the reels through the whole roping system with the help of the mass of the counterweight. Finally, the second ends of the hoisting ropes are fixed to the car side rope terminal and tightened to the correct tension.
METHOD OF CONSTRUCTING ELEVATOR AND CONSTRUCTION-TIME ELEVATOR ARRANGEMENT
The invention relates to a method of constructing an elevator comprising providing an elevator car in a hoistway, said elevator car comprising a cabin frame, and a temporary pulley beam detachably mounted on the cabin frame; mounting a hoisting machine in a first position which first position is at a first vertical level in the hoistway; suspending (first suspending) the elevator car with a hoisting roping from the hoisting machine via said temporary pulley beam; moving the elevator car in the hoistway with the hoisting machine while it is in said first position and suspended by the roping via said temporary pulley beam; mounting a hoisting machine in a second position which second position is at a second higher vertical level inside a machine room located above the hoistway; removing the temporary pulley beam from the elevator car, comprising detaching the temporary pulley beam from the cabin frame; suspending the car with a hoisting roping from the hoisting machine mounted in said second position via said cabin frame without said temporary pulley beam; moving the elevator car in the hoistway with the hoisting machine while it is in said second position and the car is suspended via said cabin frame without said temporary pulley beam. The invention also relates to an elevator arrangement for implementing the method.

Rope storage unit and a method for installing an elevator rope
A rope storage unit for storing an elevator rope during transportation and/or installation of the elevator rope includes a rope reel, formed by a rope wound in a spiral form and having a central axis; and a support frame provided with an inner space inside which the rope reel is positioned supported by the support frame such that it can in use be rotated in the inner space for unwinding the rope. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form, and wherein the support frame comprises three or more rotatable support rollers delimiting the inner space and surrounding radially the rope reel. A method for installing an elevator rope implements the rope storage unit.

Elevator system suspension member termination
A suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.
