LSD hydraulic lifting system is a construction machinery for realizing the construction of super-island, super-large and super-heavy large-scale building components in the field of building construction, which adopts the construction method of assembling the building components on the ground, lifting and hoisting them into place through the joints, and requiring the components to maintain a high degree of balance in the process of the overall lifting. It adopts steel strand bearing, lifting jack cluster, computer control, hydraulic synchronization overall lifting principle.
