Elevator construction arrangement and method

Abstract

An elevator construction arrangement includes: a hoistway; an elevator car, a counterweight, car guide rails, and counterweight guide rails; an elevator hoisting machinery and a high friction coated suspension roping mounted on first and second rope suspenders and arranged to suspend the car and the counterweight during construction time use; a protection deck mounted within the hoistway during an elevator jump operation in the hoistway; a hoist device configured to move the car or at least parts of the car below the protection deck, the car being guided on the car guide rails. The arrangement includes, arranged on top of the car, a first folding pulley beam with first folding pulleys having a small or reduced diameter, and a smaller bending radius of the high friction coated suspension roping is adapted to cooperate with the small or reduced diameter of the first folding pulleys.
