XLB Series
The Oleo XLB range of gas hydraulic buffers is designed specifically for high rise buildings where elevator speeds reach up to 10m/s (using approved speed limiting devices).
Product Introduction
The Oleo XLB 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 (other than statutory inspections) buffers is applied to the XLB range and ensures an easy installation process and the best safety buffer solution throughout the service life of the elevator.
These products are designed and manufactured according to strict engineering principles and are universally approved and globally certified.
