Edbro success in tilt test trials
Tilt tests carried out in South Korea show Edbro cylinders as the clear choice for superior performance. Daimler Automotive Korea (hereinafter DAK) offers a high specification tipper chassis in a market with extremely challenging working conditions. An important choice in developing the specification of the Euro 5 Mercedes-Benz Actros tipper was the brand of tipping gear, tipping hydraulics clearly being a critical choice for both the performance and the reliable operation of the whole vehicle. DAK decided that a series of tests were required to establish which brand of tipping gear provides the best performance in terms of total kit weight, reliability in operation and speed of tip.
On the first selection criteria Edbro offered a clear advantage achieving a kit weight saving of 40kg >10% with the lightweight laser welded CS cylinder and a selection of kit components such as the Aluminium EBA090 piston pump and the CT200 valve.
The second criteria is a little more difficult to assess however with over 90 years of cylinder design and manufacturing experience the Edbro brand guarantees the ultimate in reliability and durability. However DAK were not expected to simply take Edbro's word for this and endorsements from a selection of major international fleets were provided, many of which include the phrase which has become synonymous with the Edbro brand "fit & forget".
DAK however wanted to challenge these claim and have a measure by which they could be sure to have made the correct choice for long term durability, so they decided to perform a series of tests. The tests were designed to ensure that in even the most challenging working conditions the cylinders would meet the highest demands that they may be subjected to.
The DAK tests involved subjecting two chassis, one fitted with Edbro and one with a competitor's brand, to two tests. The first investigated the deflection of the body from the cylinder when tipped on slopes of differing heights. In this test the Edbro cylinder showed less deflection at varying body tip angels and in varying floor angles, proving the stability offered by the laser welded one piece tube design of the Edbro CS which has thick section overlaps that resist side load.
The second test investigated the impact of cross-twisted steering and tandem axles. Once again the Edbro cylinder proved more effective than the competitor's product, completing both tests with no cylinder damage. This demonstrated the ability of the CS range to tip and lower in even the most arduous conditions.
On the third selection criteria speed of tip, once again Edbro were able to provide a clear advantage since the one piece laser welded tube design allows high speed tipping and when used in conjunction with the EBA090 piston pump and the CT200 valve the CS15 recorded an impressive tipping time.
"These test results prove that the Edbro CS is the optimum choice for all applications providing the lowest weight solution yet achieving the highest standards of performance in terms of stability, reliability, safety and tipping speed. These features all come as standard with any Edbro cylinder." Peter Smith, Edbro Sales & Marketing Director explains the significance of these results. "The positive outcome of these tests will help to cement our relationship with DAK for the foreseeable future and has secured yet another major new account for Edbro."
