10 MN universal testing machine for installation in the structural engineering laboratory

oratory at ETH Hönggerberg, Zurich. The machine must fulfil the following technical requirements: Vertical axis: 10 MN compressive force / 6 MN tensile force; able to accommodate specimens with heights ranging from 1,000–5,000 mm; independent crossheads, main cylinder stroke length of 500 mm; dynam

ic capability up to 250 mm/s and 10 Hz (±2 mm sinusoidal); measurement accuracy Class 0.5/1 Horizontal actuators: Two opposing horizontal cylinders (1 MN compression / 700 kN tension), height-adjustable 500–2,500 mm, synchronisable with ver
