Hydraulic - FAIRFIELDS

Hydraulic systems sit at the heart of many critical assets, from moving bridges and tidal gates to lifting platforms and heavy industrial machinery.

At FAIRFIELDS, we design, refurbish and upgrade hydraulic systems that operate safely and reliably in high-risk, high-consequence environments. Whether supporting new infrastructure or extending the life of ageing equipment, we deliver fully integrated hydraulic, mechanical, electrical and control solutions that improve resilience, maintainability and operational performance.

We provide complete hydraulic solutions across the full asset lifecycle, from feasibility and detailed design through to installation, commissioning and ongoing support. Our multidisciplinary team combines mechanical, electrical, instrumentation and control expertise to ensure hydraulic systems are not only robust but fully integrated into the wider operational environment.

Our experience spans hydraulic cylinders, power packs, manifolds, pipework systems, lifting mechanisms, locking devices and associated control systems. We regularly deliver upgrades and refurbishments where reliability, resilience and safety are paramount — particularly within moving structures and waterways assets where availability is critical.

We focus on eliminating single points of failure, improving maintainability and reducing operational risk. This includes redesigning hydraulic circuits, pipework systems, upgrading actuation methods and integrating modern control and diagnostic capability.

Because we operate as one integrated organisation, our Engineering, Control and Digital capabilities work together from the outset. The result is a cohesive hydraulic solution that performs mechanically, operates intelligently and remains secure and supportable for the long term.

What We Deliver

From concept to lifetime support, our hydraulic solutions typically include:

• Hydraulic system design and flow calculations

• Power pack specification and delivery

• Cylinder design, replacement and refurbishment

• Pipework design and installation

• Manifold block redesign and upgrade

• Integration with PLC and safety control systems

• Asset inspections and obsolescence reporting

• Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT)

• Load testing and commissioning

• Preventative maintenance and 24/7 support frameworks

But what does it included?

Hydraulic Power Units (HPUs)

We design and supply hydraulic power units tailored to the application and environment. From compact systems to large multi-actuator installations, our designs prioritise efficiency, maintainability and resilience. We consider duty cycles, redundancy, access constraints and environmental factors to ensure long-term operational reliability.

Cylinders & Actuation

Hydraulic cylinders are often critical to asset availability. We provide inspection, refurbishment and full replacement services, including temporary works planning where access is restricted. Our approach focuses on restoring performance while improving durability and future maintainability.

Hydraulic Control & Integration

Hydraulic performance depends on intelligent control. We integrate hydraulic systems with PLC platforms, safety systems and supervisory control to deliver accurate positioning, smooth operation and real-time diagnostics. This ensures the mechanical and control elements operate as one coordinated system.

Lifecycle Support

Hydraulic systems require structured maintenance to remain safe and reliable. We provide preventative maintenance, inspection, testing and support. Our service agreements are tailored to each asset, helping clients reduce downtime and extend operational life.
