This equipment has been developed in order to connect 1290TON G/C and 450TONG/C in parallel. Like the image below, install the LIFTING BEAM in between 1290TON G/C’s UPPER-TROLLEIES and install BLOCK LOADER on L/B’s HOOK and 450TON G/C’s LOWER-TROLLEY. Through development of asymmetric B/L by structural analysis, it solved the limitation of capacityby enabling connection of different G/Cs in parallel and increased productivity by increasing capacity.
