Oleo has developed a modular Coupling
and Anti-climbing system specially designed 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 couplers and anti-climbers are
designed to work together 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 and Anti-
climbing devices:COUPLERS
Standard coupler 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 with EN15227.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.ANTI-CLIMBERS
Deforming tube technology for improved crash
performance (low force and high force options). Standard fixed length and design per stroke.
Extensive range of available strokes.
Standard Anti Climber head profile and
Mounting Plate design. Product advantages
Modular range of Coupler and Anti-climber
options to suit Metro project requirements.COUPLERS
Oleo"s Coupler Devices enable:
Lower price per Train Set.
Lower Life Cycle Costs.
Weight saving.
Faster Coupling Speeds.
Reduced Potential Impact Damage.
Increased Passenger Protection.
Performance optimisation at no cost with pre
loads ranging from 40kN to 450kN.Low mass design with higher recoverable
energy absorption than any alternative solution.Maintenance free between major train
overhaul periods.Standardised modular design with clamp
connections for ease of service.ANTI-CLIMBERS
Performance can be fully optimised with Oleo
1D Rail at no additional cost.
Controllable and predictable deforming forces across the complete stroke. Near 100% energy absorption e?iciency.
Standard mounting options for ease of
customer selection. Designed to withstand vertical o?sets
(±40mm from axis).Low force (up to 500kN) andHigh force (up to 1000kN)
