Abstract
The invention also relates to a method for installing an elevator provided with a machine room and suspended by hoisting ropes (15) and moving along guide rails (2) during the construction stage of building. The elevator is provided with a hoisting device (17), by means of which the machine room (4), which is initially placed in the lower part of the elevator shaft (1), is lifted through one or more floor-to-floor distances at a time in the shaft in such manner that at least the vertical forces resulting from the lifting are transmitted to the bottom structures of the building substantially via the guide rails (2) already secured.
Claims11
A method for installing an elevator provided with a machine room, an elevator car and hoisting ropes, comprising the steps of:
- securing car guide rails in a building during the construction stage;
- initially placing the machine room on the car guide rails in the lower part of an elevator shaft;
- mounting a hoisting device on the machine room;
- connecting said hoisting device via a hoisting rope to a securing structure supported by and attached to upper ends of the car guide rails;
- lifting the machine room along said car guide rails through one or more floor-to-floor distances at a time in the elevator shaft and securing said machine room to said car guide rails;
- thereby transmitting forces resulting from lifting the machine room to bottom structures of the building substantially via the securing structure and the car guide rails.
Apparatus for installing an elevator provided with a machine room, elevator car and hoisting ropes, comprising:
- car guide rails secured in a building during the construction stage;
- said machine room being secured to and movable on said car guide rails in a lower part of an elevator shaft;
- a hoisting device mounted on said machine room for lifting said machine room;
- said hoisting device being connected to a securing structure supported by and attached to upper ends of the car guide rails,
- wherein when the hoisting device lifts the machine room along said car guide rails through one or more floor-to-floor distances at a time in the elevator shaft, at least the vertical forces resulting from lifting the machine room are transmitted to bottom structures of the building substantially via the securing structure and the car guide rails.
