Product Introduction

The Versatile Powerhouse of Mid-Range Safety: The MLB Series

The MLB Series is the definitive choice for elevators operating in the low-to-medium speed category with mid-range mass requirements. By utilising advanced gas-spring technology, the MLB range provides a premium, robust safety interface that bridges the gap between standard passenger lifts and high-capacity systems. It is engineered for developers who refuse to compromise on strength, even in mid-market applications.

Why the MLB Series Stands Apart:

  • Compact Gas-Spring Innovation: The MLB delivers the superior energy-absorption characteristics of a gas-spring system in a design that is significantly smaller and lighter than many alternatives, providing more freedom in your hoistway layout.

  • Streamlined Logistics & Installation: To accelerate your project timeline, our MLB13-32 units can be supplied pre-filled with oil. This reduces logistics costs and eliminates the risk of on-site filling errors, ensuring a perfect installation every time.

  • Engineering Without Compromise: Built to Oleo’s uncompromising “Zero-Failure” standards, the MLB range is universally approved and globally certified to meet the most rigorous international safety codes.

  • Premium Protection for Mid-Mass Lifts: Designed to offer a sophisticated, controlled deceleration for mid-mass cars, the MLB ensures a high-end passenger safety experience across a wide variety of commercial and residential applications.
