Hydraulic lifts are a reliable choice for many low- to mid-rise buildings, known for their reliable performance and load-handling capability. But like any mechanical system, components age over time, performance can decline, and safety standards evolve. When that happens, refurbishment offers a cost-effective alternative to full replacement.
A hydraulic lift refurbishment focuses on upgrading or replacing key components to restore efficiency, reliability, and compliance with modern standards. Below, we break down the main items typically refurbished during a hydraulic lift modernisation project.
1. Control System Upgrades
Older hydraulic lifts often use relay-based or outdated electronic control panels that lack modern efficiency and diagnostic capabilities. During refurbishment, these are replaced with new microprocessor or variable-frequency drive (VFD) systems that allow smoother control, energy savings, and better fault monitoring.
Modern control panels can be programmed to improve ride comfort, speed regulation, and door operation timing. They can also integrate with remote monitoring technology, allowing facilities managers to detect faults early and schedule maintenance more effectively.
2. Hydraulic Power Unit Refurbishment
The power unit is the heart of any hydraulic lift, containing the pump, motor, valve block, and oil reservoir. Over time, these components experience wear that can cause noisy operation, oil leaks, or slow travel speed.
A typical refurbishment includes cleaning or replacing the pump and motor, recalibrating valves, and fitting energy-efficient motors. Upgraded valves help maintain precise control over the lift’s movement, while a modern power pack design reduces vibration and improves overall performance.
Regular maintenance of the power unit can also cut energy consumption and extend the lifespan of the hydraulic system as a whole.
3. Cylinder and Piston Refurbishment
The hydraulic cylinder and piston are responsible for lifting and lowering the car. Over years of use, these parts can show signs of corrosion, wear, or seal deterioration. Fluid leaks or uneven lift movement are common indicators that refurbishment is needed.
A refurbishment project may involve replacing seals, inspecting and re-lining cylinders, and upgrading safety valves. Modern cylinder technology also includes anti-corrosion coatings and improved materials that provide greater durability and compliance with current EN81-20 safety standards.
4. Hydraulic Fluid and Filtration
Hydraulic fluid plays a vital role in ensuring smooth operation. Over time, oil can degrade, become contaminated, or lose its viscosity. This leads to inefficient performance, noise, and increased wear on components.
Refurbishment includes draining and flushing the old fluid, cleaning the reservoir, and replacing filters. New, high-quality hydraulic oil helps maintain optimal pressure and temperature, ensuring consistent lift performance. A clean, well-maintained system also reduces energy use and extends the lifespan of pumps and valves.
5. Lift Car and Door Equipment
Refurbishing the lift car and door mechanisms improves both reliability and passenger experience. Door operators and sensors are critical for smooth entry and exit, yet are often among the most heavily used components.
Modern door systems use advanced control logic to coordinate with the lift’s movement, resulting in faster, quieter, and safer operation. Upgrading sensors enhances safety, ensuring doors respond accurately to passenger movement.
Aesthetic refurbishments, such as replacing lighting, panels, flooring, or handrails, can give the lift car a modern appearance without requiring a complete rebuild. These upgrades are particularly popular in residential and hospitality settings, where passenger perception matters.
6. Electrical and Safety Enhancements
Safety remains the top priority in any refurbishment project. Hydraulic lift upgrades often include new overspeed protection devices, alarm systems, and emergency lowering mechanisms. These features ensure compliance with current regulations and enhance passenger protection during power outages or technical faults.
Refurbishment may also involve replacing wiring, updating shaft lighting, and installing energy-efficient LED systems. Together, these upgrades reduce power consumption and bring the lift’s electrical system in line with modern safety standards.
7. Performance and Ride Comfort Improvements
Beyond mechanical repairs, refurbishment also focuses on how the lift feels to passengers. Replacing worn guide shoes, buffers, and damping systems can dramatically improve ride smoothness and reduce vibration or noise.
Upgrading control valves and software allows for better acceleration and deceleration control, giving passengers a smoother, more comfortable journey. These refinements also reduce wear on key components, helping maintain long-term reliability.
Conclusion
Refurbishing a hydraulic lift involves more than just replacing old parts — it’s about improving efficiency, reliability, safety, and passenger comfort. By targeting specific components such as the control system, hydraulic power unit, and safety devices, building owners can extend the lifespan of their lifts while keeping costs under control.
