The Oleo LB 50-60 gas hydraulic buffer range is designed specifically for high speed elevator applications typically seen in high rise buildings where speeds over 5 m/s are achieved. If approved terminal speed limiting devices are employed by applying the reduced stroke calculation the LB 50-60 can deal with speeds up to 11.62 m/s.
The Oleo principle of designing self contained, maintenance free* buffer units is applied to the LB50-60 series of buffers and offers an easy installation process, this makes Oleo buffers the best solution for the life of the installation.
The LB series is designed and built according to strict engineering standards and is universally approved and globally certified.
