LT Series
The LT oil bu er series is a self contained, maintenance free* unit designed for low and medium speed applications.
The LT series is designed to be low cost while maintaining Oleo’s recognised performance standards.
Oleo’s LT bu ers weigh approximately half of a conventional bu er and have a small space envelope, this gives more freedom for elevator pit design and also means that shipping costs are significantly reduced.
The LT series is designed and built according to strict engineering standards and is approved and certified for EN81 and GB standards.
