Accurate levelling of lifts is essential not only for the comfort of users, but also for their safety. Poor levelling can cause serious accidents, which is why it is crucial that lifts comply with current regulations. In this article, we explore the minimum measures that must be implemented in existing lifts to ensure proper levelling and present GMV’s recommended solutions to achieve this.
What minimum measures must be implemented in existing elevators?
Stopping and Leveling Accuracy
According to the UNE EN 81-20 standard, lifts must comply with a stopping accuracy of at least ±10 mm (5.12.1.1.4) and a levelling accuracy of ±20 mm (5.9.2.2.2). These values must be achieved with decelerations during the braking process that do not exceed gravity. These specifications are essential to prevent misalignments between the floor level and the lift, which can cause trips or falls.
Deadlines for Incorporating Measures
The deadline for implementing these measures is one year in two specific situations:
- In case of accident due to lack of leveling.
- When a change is made to the elevator's traction group.
Complying with these deadlines is vital to ensure user safety and avoid penalties for non-compliance with regulations.
Solutions to improve poor leveling and stopping accuracy
GMV offers a range of products that meet the stopping and levelling precision requirements of the UNE EN 81-20 standard. Below we highlight three groups of valves for hydraulic lifts that we recommend:
Valve Group 3010 2CH A3
This mechanical valve group features an integrated double safety lock and complies with EN 81.20-50. It does not require DLV, which simplifies its installation and maintenance. Its main features include:
- Capacity: 55-216 l/min
- Minimum static pressure: 12 bar
- Maximum static pressure: 45 bar
- Working temperature: 5-70°C
- Leveling accuracy on the ground: ± 5 mm
Valve Group 3100 2CH A3
Designed to offer maximum comfort, this valve group complies with EN 81.20-50 and offers the following advantages:
- Double integrated security system
- Reduction in engine power compared to a traditional mechanical valve
- Electronically adjustable speed
- Not affected by variations in fluid pressure and temperature, eliminating the need for heating resistors
NGV A3 valve group
The NGV A3 electronic control units comply with EN 81.20-50 regulations and are equipped with advanced features to optimise their performance:
- Self-control, precision and double safety system independent of the control panel
- Reduction of installed power by up to 40% with DRY plants
- Use of ecological fluid, respectful of the environment
- Easy regulation with programming console and digital pressure and temperature control
- Integrated programmable microSD memory card
Compatibility and Certification
All of the above products can be installed in any existing lift on the market, regardless of the brand . In addition, the entire GMV product range is certified to comply with the new ITC, ensuring compliance with the latest regulations.
Conclusion
Elevator levelling accuracy is essential for user safety and accessibility. GMV offers advanced, certified solutions that not only comply with current regulations, but also improve the comfort and efficiency of elevators. Ensure the safety of your users with GMV's high-quality products.
