Design and analysis of lifting tackle for armor plates in sinter machine

Sintering is an agglomeration process of fine mineral particles into a porous mass by incipient fusion caused by heat produced by combustion within mass itself. Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at sinter plant. The task performed here is maintenance of armor plate in sinter machine. The lifting tackle is used to handle the armor plate. The need of tackle is for adjusting the armor plate. The main constraints of this task are the position of armor plate which has only confined space and It is difficult to handle effectively. The other constraint is weight of the armor plate which weighs about 8ton and plate are in the elevation of the shop. So, there is no such facilities to handle these items. Even it is difficult to use the normal cranes. So, we need a special arrangement to adjust such a heavy item. The arrangement named “Lifting tackle for armor plate”. It contains lifting tackle with counter weight. There is a proper mechanism to counter weight and safe removal of counter weight. The operation of tackle initially loaded with counter weight at another end. Initially the tackle is developed without using patch plates but observed many deflections. Later it is developed by using patch plates which has given better results comparatively.
