Abstract: The arrangement comprises a hoisting machinery, an electric cabinet, and cable drums positioned at the bottom of the shaft, an elevator car and a counterweight moving in the shaft, upper pulleys and rope suspenders fixed at an upper end of the lifting height of the construction elevator, and hoisting ropes being fixed to the rope suspenders during the operation of the construction elevator and gliding through the rope suspenders during an upwards jump of the construction elevator in the shaft. The hoisting ropes pass in a 2:1 roping between the car, the upper pulleys, the traction sheave, the counterweight, and the rope suspenders.

Abstract: The invention relates to a construction arrangement of an elevator, comprising a hoistway formed in a building, the hoistway comprising at least one hoistway opening leading in horizontal direction out from the hoistway, the opening being delimited by a lower edge structure and an upper edge structure; and a load in the hoistway lower than said opening; and a hoisting arrangement for hoisting said load, wherein said hoisting arrangement comprises a support structure mounted higher than said load; and a hoisting device; and at least one flexible tension member connected or at least connectable to said load; wherein the at least one flexible tension member is movable with said hoisting device in particular for thereby transmitting a hoisting force to said load to be hoisted.

Abstract: The invention relates to a construction arrangement of an elevator comprising a hoistway; a protection deck mounted inside the hoistway for protecting the portion of the hoistway below it from falling objects; wherein the protection deck comprises a cover extending across the hoistway covering the hoistway such that it blocks objects from falling into the hoistway below it; and a frame mounted on stationary structures of the hoistway; and a hoisting apparatus for hoisting construction material below the protective deck. The hoisting apparatus is supported by the protective deck, the hoisting apparatus comprising a hoisting machine mounted on protection deck, and a flexible tension member movable with the hoisting machine.

Abstract: The installation platform comprises two decks and a support frame comprising horizontal support beams supporting a respective deck and vertical support beams. The installation platform has a width in a first horizontal direction between the guide rails, a depth in a second horizontal direction perpendicular to the first horizontal direction. The installation platform is guided movably via guide means on the guide rails. At least one of the width and the depth of the installation is adjustable in order to adjust the horizontal dimensions of the installation platform according to the horizontal dimensions of the shaft.
