Pressure Dynamics provides specialised crane modification and upgrade services, helping clients extend the operating life, capacity, and functionality of legacy lifting systems. Our in-house engineering, hydraulic, mechanical and electrical teams work together to deliver tailored solutions for crane modernisation – ensuring compliance with current standards, enhanced performance, and reduced risk of downtime or obsolescence.
Crane Modifications & Upgrades
Whether driven by major component failures, increased lift requirements, structural fatigue, or operator strategy, we deliver cost-effective upgrades in line with OEM recommendations and industry standards. From concept engineering to site execution, we manage complex modifications to ensure safety, integration, and ongoing crane reliability in any environment.
Major Component Replacement
Cranes often operate well beyond their original design life, requiring the replacement of critical structural or drive components to maintain safety and performance. Pressure Dynamics delivers complete changeout solutions for structural components, slew rings, winches, wire ropes, blocks, gearboxes, and hydraulic cylinders. Our approach includes detailed engineering validation, load path alignment, and safe execution using specialist rigging teams and detailed procedures.
Services include
- Slew bearings including flange face machining and bolt torquing
- Hoist drums and complete package assemblies
- Hydraulic cylinders
- Booms and bridge beams
- Powerpacks and HPU’s
- Wire rope replacements with back tension
Boom Replacements & Structural Modifications
Crane booms can require full replacement or structural strengthening due to fatigue, damage, or new lifting profiles. Pressure Dynamics offers full-service boom replacement and modification support, including reverse engineering, stress modelling, and class approvals. We manage transport, rigging, installation, and all re-commissioning tasks to return the crane to full service with complete and traceable documentation.
Services include
- Engineering assessment of boom condition and fatigue life
- Supply and transport of new or modified boom structures
- Lattice or chord replacement including provision of welding specification
- Boom foot pin, connection pin or connection bolt replacement
- Class interface for approvals and final load testing
- Re-commissioning and updated lift charts
Hydraulic System Upgrades
Legacy hydraulic systems often suffer from obsolescence, poor reliability, and inefficiency. Pressure Dynamics provides complete hydraulic system upgrades including new pumps, motors, valves, hoses and controllers. We engineer, supply, install, and commission hydraulic upgrades that optimise performance, reduce downtime, and comply with modern safety standards.
Services include
- Pump and valve block upgrades for improved flow and control
- Replacement of obsolete hydraulic manifolds with new assemblies
- Modernisation of accumulators, filtration, and return systems
- HPU upgrades and integration with new hydraulic circuits
- Complete hose replacement including hose supports and edge protection
- Pressure testing, system tuning and commissioning
Mechanical & Drive System Optimisation
Older cranes often suffer from mechanical wear, poor brake performance, or drivetrain inefficiencies. Our mechanical team delivers targeted upgrades to brake systems, slewing/travel drives, hoisting gearboxes, and rotating assemblies. These upgrades are engineered to reduce failure rates, improve torque transfer, and meet updated OEM or industry standard requirements.
Services include
- Hoist package upgrades to provide greater lifting capacity or improved operation
- Brake system redesigns
- Gearbox replacements with suitable ratios for operational duty cycles
- Coupling and alignment improvements to reduce wear
- Slew drive improvements with torque and backlash tuning
Engineering & Custom Design Solutions
Our in-house engineering team supports bespoke crane modifications where off-the-shelf solutions are not viable. Using advanced 3D modelling, FEA, and hydraulic simulation, we design and validate upgrade solutions that address specific crane limitations or operator requirements. Whether it’s a new lifting point, stability enhancement, or integration of monitoring technology, we ensure full compliance with safety and design standards.
Services include
- Obsolescence studies and identification of suitable replacements
- Reverse engineering of legacy crane components or systems
- Load path analysis and redesign
- Hydraulic digital twin modelling and performance validation
- FEA for structural assessments and fatigue improvement
- Lift planning and engineering
Documentation & Certification
All modifications and upgrades are fully documented to meet regulatory, OEM, and industry requirements. We prepare engineering dossiers, updated maintenance procedures, commissioning reports, and interface documentation for operator acceptance.
Services include
- Engineering design reports and structural calculations
- Updated crane operation and maintenance documentation
- Load test planning and execution records
- Material and traceability certificates
- OEM deviation or compatibility assessments
- CMMS integration and asset tag updates
