XLB Series
The Oleo XLB range of gas hydraulic buffers is designed specifically for high rise buildings where elevator speeds reach up to 10m/s (using approved speed limiting devices).
Engineering for the Skyline: The XLB Series
The Oleo XLB Series is our premier gas-hydraulic solution, specifically engineered for the vertical challenges of modern high-rise architecture. Designed for high-speed applications where velocities exceed 5 m/s, the XLB range provides the massive energy absorption capacity required for the world’s most ambitious towers. When paired with approved terminal speed-limiting devices, this powerhouse range can manage elevator speeds of up to 11.62 m/s, making it a cornerstone of high-performance skyscraper safety.
Why the XLB Series Leads the High-Rise Market:
-
Unrivaled Velocity Management: Whether operating at a standard high-speed of 10 m/s or pushed to 11.62 m/s via reduced stroke calculations, the XLB provides a sophisticated, controlled deceleration for high-velocity systems.
-
Massive Load Capacity: With a robust mass range of 1,250 kg to 10,000 kg, the XLB is built to protect heavy, high-capacity elevator cars, ensuring total safety for high-occupancy buildings.
-
Self-Contained & Maintenance-Free: True to Oleo’s core engineering philosophy, the XLB is a fully self-contained unit. Aside from statutory inspections, it remains maintenance-free throughout its service life, significantly reducing the long-term cost of ownership.
-
Seamless Global Integration: Designed and manufactured to our most rigorous “Zero-Failure” standards, the XLB is universally approved and globally certified. It is the “safety-first” choice for international developers and consultants who demand the best for their flagship projects.
The XLB Series: Providing the ultimate failsafe for the world’s most iconic high-speed elevators.
