Product Introduction

The Global Icon of High-Performance Safety: The LB Series

The LB Series is the industry’s premier choice for medium-to-high speed, high-mass elevators. Utilising advanced gas-spring technology, this range delivers a robust and sophisticated safety solution for the world’s most demanding vertical transport systems. With a legacy spanning over 30 years and a presence in thousands of the world’s most iconic landmark buildings, the LB series is synonymous with proven endurance and elite engineering.

Why the LB Series Remains the Global Standard:

Gas-Spring Sophistication: Engineered to manage high-mass loads with precision, our gas-spring technology ensures a premium, controlled deceleration for passengers, even at higher velocities.
A Legacy of Reliability: Installed in thousands of high-profile structures worldwide, the LB series offers three decades of field-proven performance, giving developers and consultants total peace of mind.
Logistical Intelligence: To optimise your project’s supply chain, LB buffers can be shipped in a compressed state. This significantly reduces the storage footprint and slashes transportation costs without compromising out-of-the-box readiness.
Unrivaled Certification: Built to Oleo’s uncompromising engineering principles, the LB range is universally approved and carries a comprehensive suite of global certifications, making it ready for deployment in any territory.

The LB Series: Engineering excellence that has protected the world’s skylines for over three decades.
