Shock AbsorbersLR SeriesShock AbsorbersEnd of track stops by JARRET are shock absorbers which can be fitted on to a steel or concrete fixed structure accordingto the customer's specifications. The JARRET LR series is suited particularly well for such applications, and customdesigns are also available to meet customer specific needs. Fixed track stops are generally used for impact speeds upto 10/15 km/h. Buffer selection is a function of the energy to be absorbed and of the maximum impact force allowedby the train structure. For higher impact speeds, the stopping distance of the train is critical, and the use ofa sliding track stop is then necessary for adequate safe deceleration. In this application the energy is absorbed anddissipated by the friction between the brake shoes and the rails.The addition of several buffers to a standard sliding track stop adds the following advantages:• At the moment of impact, the energy needed to initiate movement of the sliding track stop is smoothlycontrolled. The buffer allows the train to avoid a high peak speed which could damage the train structure.• In the case of slower impacts, only the JARRET unit absorbs the energy and the sliding does not need to be reset.In addition to the buffer, a specific impact plate has been designed to ensure that the track stop will match correctly withthe train impact zone.Example of a fixed track stop for trains using a central coupling and side buffersExample of a sliding track stop for trains using a central coupling13 www.jarret.fr Email: contact@jarret.fr Tel. +33 1 41 32 26 60 Fax +33 1 40 86 12 82

SpringsSpringsJARRET devices are designed and built onthe principle of the compression, shearcharacteristics of specially formulatedsilicone compounds (JARRET patents).These characteristics enable the JARRET device tobe designed as an energy storing device (a spring)or an energy dissipating device (a shock absorber)or a combination of both.By modifying the geometry of the unit and selectingan appropriate silicone compound the emphasis canbe placed either on the energy storing function or onthe energy dissipating function.SpringsOperating Conditions of JARRET SpringsFReservoirSiliconeSealsGuide RingStationary PistonThe load “F” forces the reservoir over the stationary piston.The silicone is compressed by the volume displacement of thestationary piston.Advantages:1 - Extremely compact.2 - Dependable retention of initial characteristics,even after years of non-use.3 - Easy installation.4 - No maintenance.5 - No adjustment necessary in service.6 - Elimination of any additional devices forpre-loading because the silicone has beenpre-stressed during initial charging.7 - Appreciable service life: in normal operatingconditions it may reach 5 to 10 years.Main Application: JARRET Springs for Work Roll Chock Separation in Millswww.jarret.fr Email: contact@jarret.fr Tel. +33 1 41 32 26 60 Fax +33 1 40 86 12 8214
