Hydraulic Jacking Systems for Non-Conventional Lifting Operations

Whenever high lifting capacities and significant engineering support are required, Autovictor hydraulic jacking systems provide the ideal solution. Autovictor operates a synchronized lifting system controlled by an Enerpac PLC-based hydraulic power unit capable of managing up to 24 lifting points simultaneously, with a total lifting capacity of up to 5,500 ton. Autovictor hydraulic jacks apply controlled loads to structures through either pushing or pulling actions, using dedicated reaction frames. This technology ensures uniform load distribution and synchronized movements with millimetric precision, making it ideal for lifting, replacement, or positioning operations involving heavy components where cranes cannot be employed. One of the key advantages of Autovictor hydraulic jacking systems is the extremely precise control of the applied load, allowing progressive loading sequences and real-time monitoring through load cells and sensors.

Hydraulic jacks are devices designed to generate significant lifting or pushing forces by means of hydraulic oil acting within a cylinder. Within the Autovictor operational framework, hydraulic jacks play a fundamental role in several typical applications, including the lifting of precast structures (industrial buildings, bridges and viaducts), elevation of existing infrastructures, securing and levelling heavy loads prior to transportation using SPMTs or mobile cranes, and load adjustment on bearing plates, among others.

The use of hydraulic jacks offers several technical advantages:

• They enable high-capacity lifting operations while maintaining relatively compact dimensions, providing greater flexibility compared with the exclusive use of mobile cranes.

• They offer precise control of both stroke and applied force, which is essential for levelling operations, shim insertion, load pre-distribution on bearing plates, and structural alignment.

• They can be adapted to complex site conditions where mobile cranes cannot operate, such as beneath viaducts, inside tunnels, or on already installed precast structures.

• They allow incremental lifting (jack-up) operations and temporary load support under full load, activities frequently required during bridge interventions, infrastructure raising projects, and structural relocation works.

The possibility of combining multiple jacking units makes hydraulic jacks a strategic solution for tailor-made heavy lifting and engineered transport operations.
