CRANES FOR THERMAL POWER PLANT.#3

The picture shows the erection of a Super critical unit steam generator is under progress. Cluster of crane is available for

erection. 120MT Fushun and 250 MT Kobelco are seen on the pictures doing erection of the structural member of the steam generator. Excavated area is the area of ESP . One more crane is doing some other job. In addition to the above crane a 600MT/1200MT crane has to be mobilised in the same area. All the cranes will work simultaneously in steam Generator. All three cranes will have their own angle of rotation and area . If their erection material is not identified

before it will certainly lead to confusion and may cause stoppage of on crane to give place for other crane. Also it is to been seen that very less space is available for crane operation. Therefore all the cranes boom length are to be decided before hand and boom extension and reduction  to

done as per plan only. 

The crane shown in the picture is liebeherr 150T tyre mounted all terrain crane with telescopic boom. This type of crane is best suited for erection of structure , ducts , motors , ID fan etc.

IT is easy to operates can reach far by sitting in one place. However the base or land should be plane and can carry the load of the crane. Only

difficulty of such crane is that it can not move with load or with counterweight. Counterweight 

is to be carried  separately . The advantage of this crane more than disadvantage as it can operate in comparatively less  space and boom

extension and reduction not necessary. Best suited for the wide variation of load in compact area.
