Lateral movement of lifting strings connected by screwed joints and spherical joints in deep sea by finite element analysis and virtual prototype technology;

The design and technology of the rotating construction for the cablestayed bridge of rigid cable are discussed and presented,and the views on precasting and installing of the spherical hindge,placing of rotation and draw system and slipway, selection of the friction factor are proposed.

End Cover Replacement on φ4.2m×10m Cement Mill;

Quick removal and replacement of dummy bar head of continuous caster;

Application of New Technology in Replacement of 300t-Converter Shell at Baosteel;

In order to gurantee system normal operation,we replaced the second,third and fourth supporting ring that have been damaged badly.

Many ropes of fall to the ground type rub to promote the machine to replace a cage craft complications,start construction method mainly from fix a cage of the east side the steel wire rope,take off a bottom of west the tail rope combine fixedly,hang the west bottle with to equip to take off to open,pull up the west bottle.

The craft of producing rail rope head of multi-rope friction hoist is sophisticated,and the replace method of tail rope is different according to the different mine,the safe construction problem is particularly important.
