Friction testing
High Speed Linear Friction Tester (HSLFT)
Measuring the real µ
A key solution for development engineers
HSLFT is a friction tester, neither for measurement of wear nor abrasion. Friction testing with the HSLFT is a huge step forward in the process of tire development. It reduces risk by increasing the number of test cycles offers the customer a far shorter delay of launching his product by reducing the number of road tests and cuts development costs by creating an indoor all-season tire test environment.

HDOT – High Dynamic Oscillation Tester
Biaxial transient tread oscillation machine
HDOT is a system to measure the transient response of tread-rubbers on different friction-/ road surfaces. It is based on the customers experience with the HSLFT and advanced customer needs. Geometrically standardized rubber samples are activated with high frequency in various loading conditions, bi-axial in longitudinal and vertical direction.
Road surfaces and samples are replaceable and free to configure and may be conditioned with various temperatures. This machine opens complete new opportunities to describe the material properties of elastomers.

Foot and Loadprint Tester FPT
A Foot- and Loadprint Tester for passenger car and light truck tires on a stiff H–frame design base with spindle loading of the tire. A combined spindle positioning and hydraulic loading system cares for most precise load adjustment.
Special lighting of the glass plate allows to visualize the contact patch and to record it either with a video camera or with a photo camera from underneath through the glass plate. Vertical force and deflection of the tire are synchronously measured and recorded. A special foil is available to cover the glass plate. It is calibrated for its grey scale appearance depending on the load being applied. This will be used to visualize and calculate the contact pressure distribution.
