Abstract
A method for constructing an elevator includes providing a hoisting machine unit, a guide rail line, an elevator car, a counterweight, and a hoisting roping; using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in a first position; installing one or more guide rail sections into the guide rail line above a guide rail section of the hoisting machine unit; removing the hoisting machine unit from the first position; installing a guide rail section into the guide rail line in place from where the guide rail section of the hoisting machine unit was removed; hoisting the hoisting machine unit; mounting the hoisting machine unit to a second position which is higher than the first position; and using the elevator car for transporting passengers and/or goods while the hoisting machine unit is in the second position. An elevator arrangement is described for implementing the method.
