This crane puts actually two cranes together, auxiliary crane hoist the smaller tonnage while (when) the other hoist the larger to prevent the slow hoisting and power consumption to the main crane

When used only for hoisting the smaller tonnage, instead of the fast hoisting, power-saving and facilitated operation, twin crane saves you one set to beams and the saddle seat, provides you more operation space without interference in between. Amazing flexibility in the matching of tonnage and the models.
