MLBH Series

Our MLBH series is an extension of Oleo’s MLB series. MLBH buffers are smaller and weigh considerably less than many direct alternatives for speed and mass.

Product Introduction

Enhanced Capacity, Elite Protection: The MLBH Series

The MLBH Series represents the high-capacity evolution of our MLB range, specifically engineered to handle the increased demands of heavier mid-range elevators. By utilising advanced gas-spring technology, the MLBH provides a robust and premium safety solution for low-to-medium speed systems. While the standard MLB is a global favorite, the MLBH extends that performance to a broader mass range of 500 kg to 7,000 kg, ensuring total safety for the next generation of larger, more complex elevator designs.

Why the MLBH Series is the Mid-Mass Specialist:

  • Extended Load Capability: Precision-engineered to support masses up to 7,000 kg, the MLBH offers the extra strength needed for high-capacity passenger cars and modern lifts with heavier architectural finishes.

  • Superior Power-to-Weight Ratio: Despite its increased mass capacity, the MLBH remains significantly smaller and lighter than many conventional alternatives, allowing for maximum safety in a compact hoistway footprint.

  • Plug-and-Play Installation: To keep your project on schedule, our MLBH13-32 units can be supplied pre-filled with oil. This “ready-to-install” approach slashes logistics costs and eliminates the risk of errors during on-site commissioning.

  • Market-Certified Reliability: Manufactured to Oleo’s rigorous “Zero-Failure” engineering principles, the MLBH is fully market-certified, providing an established, globally recognized safety interface for your building.

The MLBH Series: Extending the power of gas-spring technology to meet the demands of higher-mass mobility.
