The key point of concrete construction in Cihe invert siphon project are the vertical transportation of pipeline concrete placement and the construc tion of moid plate procesa Through comparing with similar engineering and analyzing the real situation, the vertical transportation and mold plate construc- tion are determined after systematic verificatioa.

In order to handle the vertical transportation in the construction of 454m tall Shanghai Broadcast Television Tower, 88HC tower crane is refitted, and self- lifting and attached type operation is adopted according to the tower construction requirments.

The layout of the vertical transportation machinery such as tower crane and construction elevator etc.

In this paper, with the aid of analytic hierarchy process, a research on the method of vertical transportation machinery of high rise buildings is made and the satisfactory results are obtained.

Aiming at solving the problem existing in construction of high rise buildings in our country,an evaluation method of the vertical transportation machinery of high rise buildings is presented based on the civil enqineering technical economics.

Study on pull-out protection strategy of vertical transportation system for permanent magnetic linear synchronous electric motor

The mechanical design demands are discussed on a kind of vertical transportation system made up of many permanent magnet linear synchronous motors (PMLSM).

This paper introduces the principle and present study situation of permanent magnet linear synchronous motor for vertical transportation system and indicates what should be researched specialiy in future.
