LCH recently conducted a lift for Rotary Kiln Services at Cement Australia, Gladstone QLD for its K2 Kiln Shutdown.
The lift required Lampson’s Manitowoc M2250 and two of LCH’s heavy lifters the Demag AC250-1 and Grove GMK5220. Each has lifting capacities of 272t, 250t & 220t respectively with boom lengths of 33.5m, 33.7m & 36.29.
The lift involved the M2250 lifting the entire weight t a radius of 10.5m. The cement kiln tyre weighed 133t with the kiln section at 50t and lifted at a radius of 12m.
LCH hired & operated the M2250 after comparing the load charts of several crawler cranes. LCH also conducted computer modelling for the lift and this also confirmed the M2250 was the standout and best crane to carry out these lifts.
Both loads were lifted out from under ducting pipe using an engineered diverter system to keep crane ropes and hooks clear. The three cranes were used to minimise crane downtime for relocation as this was the critical path of the shutdown.
