Oleo has developed a modular range of
Gas Hydraulic Couplers for the Metro
market with standard head types including Type 330 and Type 10.The couplers are fitted with the Oleo
Sentry energy absorption system with
strokes and load ratings to suit the requirements of Metro applications.All Oleo couplers have been extensively
tested to reduce Non-recurring costs and lead times - detailed test reports to be available with product supply.The Automatic coupler is designed to
work together with the Semi-permanent (Intermediate) couplers and Anti- climbers (if fitted) to provide the optimum passenger safety in the event of an accident, and all Oleo products are fully configurable with Oleo"s 1D Rail simulation software.Integration of the Sentry Energy
Absorber into the coupler system
removes the need for heavy draft springs and draft housings.By reducing the variety and complexity,
this can allow for lower project costs per train coupling system whilst also o?ering higher coupling speeds, significant weight savings and reduced life cycle costs. Light RailApplicationsProduct detailsStandard range of Oleo couplers:
Optional Type 330 or Type 10 heads with
pneumatic coupling/uncoupling (UC). Standard Pneumatic connections for MRP
(Main Reservoir Pipe) and BP (Brake Pipe). Electrical heads with high-speed data
transmission option 100Mbit. Modularised Bu?, Crash and Draft energy
capacity. Standardised car body interfaces.
Maximum Force range up to 1200kN.
Adjustable centring and support.
Bracket with integral shear o? connection.
Fully customisable force/stroke
characteristics at no extra cost. All couplers and energy absorption devices
have been tested by Oleo with validated mathematical models in accordance withEN15227. Representative elements are
available for Radioss and LS-Dyna finite element software. The system used by OLEO for the mathematical
modelling of crash scenarios is approved by aEuropean Rail Authority as being accurate,
appropriate and properly controlled. Standardised design for reduced
manufacturing lead-time and lower cost.Product advantages
Oleo"s Coupler Devices enable:
Lower price per Train Set.
