Pressure Dynamics provides expert crane maintenance and repair services to support critical lifting operations in challenging environments. We deliver comprehensive, OEM-aligned maintenance solutions across hydraulic, mechanical, electrical and safety-critical systems, helping clients maximise asset uptime and reduce operational risk. Our field service teams include highly experienced mechanical and electrical crane technicians, hydraulic specialists, and rope access personnel who are trained to work safely and efficiently on a variety of cranes and lifting equipment.
Crane Maintenance and Repair
Our services are aligned with API Spec 2C and RP 2D, AS 1418 and 2550, and the requirements of major classification societies, ensuring full regulatory compliance and seamless integration with operator maintenance systems. Whether supporting shutdown campaigns, planned maintenance or urgent repairs, we mobilise rapidly with the right tooling, documentation, and technical expertise to extend the service life of cranes and maintain safe, reliable lifting performance.
Crane Lifting and Load Path Components
Maintaining the integrity and performance of lifting components is central to crane reliability and safety. Pressure Dynamics delivers detailed servicing and replacement of all elements in the load path, ensuring compliance with operational requirements and fatigue management schedules. We support safe lifting operations by maintaining optimal alignment, lubrication, and functionality of structural members, hoists, ropes, hook blocks and sheaves. Our team also provides full load test support to validate performance in real-world conditions.
- Thorough visual and alignment inspections of structural members
- Hoist inspections, functional testing and mounting bolt tightness checks
- Wire rope inspection, lubrication, replacement and retirement based on discard factors
- Sheave alignment, groove profile inspection and bearing replacement
- Hook block dismantling, visual inspection, dimensional checks and reassembly
- Slew bearing and kingpost inspections, bearing wear/deflection tests and fastener torquing/tensioning checks
- Execution of static and dynamic load testing using calibrated equipment
Hydraulic Systems
Offshore cranes, in particular, depend heavily on high-pressure hydraulic systems for hoisting, slewing, luffing and boom extension. Our in-house hydraulic specialists manage all aspects of system performance, from pressure integrity checks to fluid cleanliness assessments. We offer predictive and corrective maintenance programs that address pump and motor performance, cylinder wear, hose ageing and fluid degradation; ensuring reliable, safe operation and extended equipment life. Our capabilities include field repairs, upgrades, and full hydraulic refurbishments on site or in our workshops.
- Hydraulic pump and motor servicing, including pressure and flow rate checks
- Cylinder inspection, overhaul, replacement and pressure testing
- Hose visual inspection, condition assessment and complete replacement
- Valve block troubleshooting, refurbishment, replacement and pressure setting
- Accumulator pre-charge checks, bladder replacement and complete unit change outs
- Oil sampling, flushing, filtration and replacement based on condition
Drive and Braking Systems
Drive and braking systems are vital to the safe and reliable operation of all cranes; particularly during heavy lifts and in dynamic offshore conditions. Our mechanical team services all rotating components including hoist and slew motors, gearboxes, brakes and couplings. We use predictive diagnostics like vibration analysis and brake torque testing to identify issues before failure. Whether it’s a simple brake pad replacement or a complete drive overhaul, we ensure all components are maintained to OEM or class requirements.
- Motor inspection, replacement, alignment and functional checks
- Brake pad, disc and drum wear measurement and replacement
- Brake stall testing under load
- Slew/travel pinion alignment, lubrication and backlash checks
- Gearbox oil sampling, seal checks and temperature profiling
- Gearbox oil sampling, seal checks and temperature profiling
Crane Electrical and Control Systems
Effective and safe crane operation requires precise and responsive electrical and control systems. Pressure Dynamics inspects, maintains and calibrates all onboard crane control functions, including joysticks, Safe Load Indicators (SLI’s)/Load Monitoring Indicators (LMI’s), Programmable Logic Controllers (PLC’s), limit switches and safety interlocks. Our technicians are experienced in diagnosing faults in both analogue and digital control circuits, as well as tuning load control devices and setting safety limits. We ensure the system responds as expected under all operational modes – reducing human error and enhancing lifting safety.
- LMI and SLI inspection, diagnostics and recalibration
- PLC and relay fault finding and troubleshooting
- Joystick and control lever inspection and signal testing
- Anti-two block (A2B) and travel limit switch functional testing and recalibration
- Emergency lowering system activation and functional test
- Remote and wired control system servicing and range testing
Documentation & Certification
Proper documentation and traceability are essential for compliance and asset management. Pressure Dynamics ensures that all maintenance work is fully recorded and certified in accordance with API RP 2D, AS 2550, classification societies and operator-specific requirements. Our teams produce detailed service logs, part traceability records, and certification packs suitable for upload into operator CMMS systems or presentation to classification bodies. We support regulatory audits, change control, and maintenance history reconciliation.
- Detailed maintenance and inspection reports
- Load test certificates and third-party validation reports
- Hydraulic and mechanical component service records with serial traceability
- Rope inspection and retirement documentation to OEM/ISO standards
- Spare parts usage logs and inventory integration for planning
- Full compliance documentation packs for class and audit readiness
