Universal testing machines inspekt H-HF Servo-hydraulic material testing machines up to 1000kN The servo-hydraulic universal testing machines of the series inspekt H-HF have been designed for routine jobs in metalworking and building materials industries. They are equipped with a mechanical wedge type grip for round and flat specimens. Furthermore, two test spaces allow for tensile, pressure, and bending tests without changeover times, which guarantees a high test throughput. If required, it is also possible to use a load frame with a user-friendly, hydraulic clamping tool. Load frame The lower crosshead of the load frame is guided with the help of two fixed spindles, which are connected to the machine base. An electric motor moves the crosshead to the necessary distance to the upper crosshead. The upper crosshead is connected to the machine bench with two load-bearing columns. The machine bench is attached to the piston of the hydraulic cylinder. Thus, the machine bench is transmitting load to the upper crosshead. Furthermore, the oil pump responsible for the hydraulics is equipped with a limiting switch, which stops every movement automatically when the crossheads get too close to each other. In total, the hydraulics unit consists of the oil pump, an oil tank, a filter, one hydraulic and one electro-hydraulic servo valve. This whole unit is stored in the lower part of the control cabinet. Load measurement To ensure exact load measurement, Hegewald & Peschke MPT GmbH has equipped its universal testing machines of the series inspekt-H with a pressure sensor in the hydraulic circuit. It contains special electronic measuring equipment.
