Leading the world in
energy absorption
The MLB series has been designed to complement the successful LB series while retaining key operational characteristics.
The MLB gas hydraulic buffer series is a self contained, maintenance free* unit designed for quick and easy installation, primarily designed for medium speed elevator applications, typical applications include low to medium rise buildings.
Oleo’s MLB buffers weigh approx half of a conventional buffer and have a small space envelope, this means that shipping costs are significantly reduced. In addition there is the option to supply the MLB 13 – MLB 32 oil filled rather than with a separate container of oil saving valuable time during elevator installation and reducing the risk of errors and spillage. The MLB 35 and MLB 40 are delivered without oil.
The MLB series is designed and built according to strict engineering standards and is universally approved and globally certified.
The MLB series provides a cost effective solution with excellent performance characteristics across an exceptionally wide mass range
