Hydraulic Actuator for offshore & onshore jacking

Advantage of hydraulic actuator and hydraulic power unit in high demanding application


The hydraulic actuator and the hydraulic power unit are fundamental tools for enhancing the capacity, efficiency, safety, and productivity across various high demanding application as jacking.

Hydraulic Solution: Active Hydraulic Actuator for Lifting System

In the world of heavy machinery and industrial applications: efficiency, precision, and safety are fundamental. Whether it’s lifting massive structures or precisely positioning heavy loads, the technology behind Atos for jacking plays a key role.

Atos has introduced an innovative smart hydraulic system designed for heavy lifting applications in industrial environments. This advanced solution combines hydraulic power with precise control mechanisms to efficiently lift massive structures and accurately position heavy loads.

The hydraulic system is composed by:
  • Hydraulic servo-actuator according to ISO 6022 norms with built-in magnetostrictive position transducer and load cell. It is manufactured with high strength materials suitable for low temperature, low friction PTFE seals and specific guide rings to withstand high radial forces.
  • Hydraulic power unit according to the Machine Regulation 2023/1230/UE, installed on board of the servocylinder and is equipped with low temperature devices, internal gears pumps, sealed reservoir in AISI 316L stainless steel, filtering, and cooling system suitable for high temperature variations.
  • Control manifold integrating ruggedized servo-proportional valves with on board digital electronic foralternated close loop controls of position, speed, and force. Safety valves, certified by TÜV, with built-in inductive proximity sensors and pressure relief valves conforming to the Machine Regulation 2023/1230/UE for load compensation, ensure top level reliability and secure the system in emergency conditions.

Electrohydraulic Solution for Cable Layer Ships

Electrohydraulic systems have emerged as a game-changer in the field of cable laying operations, revolutionizing the way modern vessels handle this crucial task. With their advanced technology and precision engineering, these systems offer an efficient solution for cable-laying vessels. By combining the advantages of both electronics and hydraulics, electrohydraulic systems provide optimal control and flexibility during cable installation.

In a lifting system, several servo actuators work synchronously to raise or lower the load. This coordinated effort ensures stability and even distribution of forces, which are crucial for safety and efficiency. Advanced control algorithms manage the position of each actuator, synchronizing their actions to achieve precise positioning or lifting sequences.
