A fastening apparatus for fastening a drive of an elevator system, wherein the elevator system includes an installation structure for installing the drive, has a beam with two feet for fastening the beam to the installation structure. The fastening apparatus includes a drive bracket for receiving the drive, wherein the drive bracket is fastened to the beam, and a support leg that is fastened at one end to the drive bracket and additionally supports the drive bracket on the installation structure.

An elevator system includes an elevator shaft, an elevator car arranged in the elevator shaft for movement, a drive unit for moving the elevator car, a machine platform that can be fastened in the elevator shaft and can be lifted along the elevator shaft, wherein the drive unit is fastened to the machine platform, and at least one lifting device for lifting the machine platform. The at least one lifting device includes a supporting element, a strand jack for moving along the supporting element, and an anchor for fastening the supporting element in the elevator shaft, wherein the supporting element is fastened in the elevator shaft by the anchor and the strand jack is arranged to move along the supporting element.

An elevator system includes a car, configured to travel through a hoistway; a first stationary drive unit, configured to be mounted in a hoistway, a first movable drive unit, configured to be functionally coupled to the car and to the first stationary drive unit, and a second movable drive unit, configured to be functionally coupled to the car and to the first stationary drive unit.

An installation tool configured to install a machine of an elevator system, including a base section including two legs, each leg including a laterally extending gusset attached thereto. A clamp assembly is supported by the base section and includes a first bracket attached to and positioned over the two legs and a second bracket attached to and positioned over the gussets. A first tube is movably carried by the first bracket and a second tube is movably carried by the second bracket. The first and second tubes are movable in the brackets between a retracted position that positions the machine over the base section and an extended position that positions the machine in a cantilevered position adjacent the retracted position. Each of the first tube and the second tube includes a tube clip that is fixed in position thereon and a first rod is movably disposed in the first tube and a second rod is movably disposed in the second tube, each of the first and second rod including a rod clip sized and shaped to releasably retain the machine on the clamp assembly in cooperation with a respective tube clip.

Disclosed embodiments provide techniques and apparatus for installing an elevator. A support frame is assembled at the top of an elevator passage. The permanent elevator motor is installed in the support frame. The permanent motor is then used to hoist materials as needed to build out the elevator system. Once built, the permanent motor that is already installed and has had hours of usage to verify its operation, is used for movement of the elevator car for the completed elevator system.

In an elevator renewal construction method, a series of divided construction work steps includes a first divided construction work step including the steps of: installing a communication-enabled hall device at each hall; installing a communication-enabled car device in a car; and installing a communication relay device and connecting the communication relay device and an old control panel to each other; connecting the communication relay device and each of the communication-enabled hall devices to each other and connecting the communication relay device and the communication-enabled car device to each other. After termination of the first divided construction work step, the old control panel is in a state of being communicable with the communication-enabled hall devices and the communication-enabled car device via the communication relay device.

The invention relates to a method for constructing an elevator comprising installing comprising installing an elevator car, a counterweight, one or more vertically oriented guide rail lines, a hoisting machine in a first position, and a first hoisting roping for being moved by the hoisting machine, said installing further comprising connecting the first hoisting roping to the elevator car and counterweight; and thereafter transporting passengers and/or goods with the elevator car vertically in the hoistway while the hoisting machine is in said first position; and thereafter stopping said transporting; and thereafter removing said hoisting machine from said first position and the first roping from the hoistway, said removing comprising disconnecting the first hoisting roping from the elevator car and counterweight; wherein the method further comprises installing a hoisting machine in a second position which is higher than the first position, and a second roping for being moved by the hoisting machine, said installing comprising, connecting the second hoisting roping to the elevator car and counterweight; and thereafter transporting passengers and/or goods with the elevator car vertically in the hoistway while the hoisting machine is in said second position, said transporting comprising moving the elevator car with the hoisting machine and the second hoisting roping.

An elevator renewal construction method includes a series of divided construction work steps, each being determined as such a unit that the elevator operation becomes normally possible after finishing of each of the divided construction work steps, wherein one of the series of the divided construction work steps comprises the steps of: replacing an old control panel of the existing elevator with a new control panel; connecting an old cable for an old car device, which has connected the old car device and the old control panel of the existing elevator to each other, to a communication conversion unit provided in the new control panel; and converting a new serial communication system to an old serial communication system by the new control panel via the communication conversion unit and the old cable to control the old car device through the old serial communication system.
