Exterior hoists have been used for over 40 years at construction sites, but there are growing concerns about their safety and efficiency. To overcome these concerns, KONE has developed an advanced self-climbing elevator, the KONE JumpLift, which increases safety on the construction site, improves cost-efficiency and speeds up construction work. The KONE JumpLift solution provides builders with a competitive advantage when tendering for projects.
The KONE JumpLift uses the building's permanent hoist way for construction time use as soon as the first floors have been completed. The KONE JumpLift has a temporary machine room that moves upward (‘jumps’) in the hoist way as the construction work progresses.
When the building structure is finished, changing over to the permanent elevator can be done quickly by installing the final machinery, signalization and the material surfaces of the elevator car and landing doors.
FasterTraffic capacity can increase three-fold compared with a traditional exterior hoist, because the KONE JumpLift travels faster and it has automatic doors.
SaferOperating under the standard EN81-1 elevator code, with standard operating panels, buttons and automatic doors, traffic with the CTU KONE JumpLift is as safe as with a standard elevator.
EnclosedWith all vertical transportation taking place inside the building, lower floors are closed up and ready for finishing much earlier. Since all transportation takes place in a dry, windproof shaft, construction activities can continue unhindered, even in bad weather.
Ready soonerAt the end of the construction phase, getting the elevator ready for normal operation requires considerably less time.
How it works
As soon as the permanent lift shaft has reached a height where it can be waterproofed, the Deflection Crash Deck is installed. Below it the Installation Platform is used for the installation of the guide rails and other elevator shaft components. Once these guide rails are in place, the KONE JumpLift machine room can move up the shaft.
The KONE JumpLift uses a temporary machine room, containing the traction machine and controls, that moves upward as the building work progresses. Below it, the permanent elevator is installed in CTU service. As the building core moves upwards, the crash deck is moved a few floors up and the installation platform moves up to install the necessary shaft equipment. Then the KONE JumpLift self-propels itself upward and the permanent elevator is again in construction time use below it.
When core construction is complete, all that remains to finish the elevator installation is to install the permanent machine room and the final aesthetics for the elevator car, doors and signalization.
