ZwickRoell, Schenk-Trebel RME 250 kN

Schenk-Trebel Materials Testing Machine Type RME 250 kN
• Load frame and drive by Schenk Trebel, year of construction 1985, total height approx. 3.3 m; traverse stroke approx. 2 m
• Modernization around the end of 2003: equipped with the ZwickRoell "testControl" control electronics
• Retrofit in 2010: MultiXtens universal extensometer system by ZwickRoell, with swiveling device and two pairs of measuring sensors (photo), and new testControl module

• Note: The testControl module functions together with the current "testXpert III" software from ZwickRoell (software is not included in this offer)
• Temperature chamber (photo) insertable into the test space of the machine, built in 2006 by RS-Simulatoren Prüf- & Messtechnik, heatable up to approx. 200°C; coolable down to approx. –40°C with liquid nitrogen
• Load cells: 250 kN and 50 kN (currently installed, see machine photo); additionally: 5 kN, 1 kN, and 500 N (photo)
• 2 wedge specimen grips (photo)

Condition of the machine
The machine was in use for testing until early 2026. The 50 kN load cell and the traverse displacement sensor were used (both sensors last calibrated on 06.05.2024 incl. standard inspection). A defect in the servo amplifier for the drive (component in the testControl module) has resulted, since autumn 2025, in frequent connection losses to the software and halt of the drive until hardware/software reboot. The servo amplifier or the entire testControl module need to be replaced (cost details available from the supplier).
The 250 kN load cell was last calibrated on 11.02.2021, but has not been used since then.
The other load cells, MultiXtens system, and temperature chamber have not been used or calibrated in recent years.
The two hydraulic clamping units shown installed in the machine on the pictures will be removed and remain with the supplier.
