Large-Bore Synchronized Lifting Hydraulic Cylinders

Large-Bore Synchronized Lifting Hydraulic Cylinders

Multi-point lifting of a bridge element, industrial structure or large machine requires coordinated movement and a clear load path. Yongjian can review cylinder drawings and lifting duty for large-bore actuators, while the lifting contractor or system integrator defines the full control and safety method. This is a project-specific product concept rather than a standard lifting capacity claim.

Application and load review

Calculate the load at each lifting point, uneven-load cases, allowable differential travel and support settlement. Provide required stroke, installed height, travel speed and expected number of cycles. Review rod stability, bearing loads, base support and the effect of side loading. The structure and jacking frame must be designed for all operating and abnormal conditions.

Configuration and integration

Cylinder interface choices include base or flange support, rod-end connection, bore and rod size, hydraulic ports and any position or pressure feedback. A synchronized hydraulic system may use measured position and flow control, but actuator selection alone does not establish synchronization accuracy. State oil cleanliness, outdoor exposure, temperature and protection requirements.

Inspection and acceptance

Agree on dimensions, proof or pressure tests, leakage, sensor checks if applicable, marking, preservation and traceable documentation. Define hold points and witnessed testing in the purchase order when needed. The complete lift plan should specify monitoring, stop conditions and safe lowering.
