The World's First Over 500 meters thermocline elevator

In August 2016,the world’s first over 500 meters Jump lift was officially put into use in the first high-rise building of Beijing.This project we called “Z15 Tower”.

The projects is located in Chaoyang district CBD core area Z15 plots,with a total construction area of 437 thousand square meters.It was 528 meters high with 108 floors and 7 floors underground.This building including the grade A offices, meeting, sightseeing and a variety of ancillary services functions, after the completion of the building will become the tallest building in Beijing.And it is expected to be completed in October 2018 and delivered to use.

The “Z15 Tower” project site construction workers can reach 3600 people,and all the personnel transport are rely on the construction elevator.While this elevator is far away from the capacity and speed requirement.During the working time, the workers can not get to work or leave the area on time, will greatly reduce the efficiency of construction.

Aiming at the problem of vertical transportation bottleneck in the process of global super high-rise project construction,the project find a new way to solve the problem,that is Jump lift elevator design.

Advance of the use of 4 duplex lift in the main construction stage (officially passenger lift), with the main construction elevator for mechanical and electrical, decoration materials and personnel transport.It is the first application of project construction process of high-rise building height over 500 meters of the jump elevator in the world service.

Application of jump elevator temporary fixed mobile machine room on top of the shaft,after the installation is completed, can be run in closed hoist way.Use the special elevator equipment,can transport the construction materials, equipment  and also workers,can effectively solve the problem of engineering capacity, improve the work efficiency of workers, and ensure the progress of the project schedule.

Use the elevator to avoid the use of ordinary construction elevator occupy the hoist-way of the formal passenger elevator and affect the future installation of the official lift installation.Also the traveling speed of jump lift is 3 times and the capacity is twice compare to the construction lift.Which greatly improve the efficiency of personnel transport in the construction stage,so that the construction progress can save a period of about 80 days compared with the general construction elevator.
