Series LF(SV) 50 - 1000 kN

The Series LF and LFSV of servo-hydraulic testing machines are compact designed and therefore especially suitable for laboratories with reduced ceiling heights. LF models with mechanically clamped and movable upper cross-head; LFSV models with hydraulically movable upper cross-head.

Servohydraulic Universal Testing Machines
The LF(SV) testing machines are ergonomically designed floor standing machines for tensile, compression, bending or shear but also strain and other more advanced tests on a wide range of different materials.The Series LF and LFSV cover the same application range as the Series TTM. Compared with the Series TTM, the dobble-acting actuator is integrated in the base of the testing machine what results in a very compact design and reduced machine height. The LFSV Models feature a hydraulically movable upper crosshead through two long stroke actuators for quick, easy and accurate re-positioning. The LF Models instead feature a mechanically clamped and movable upper crosshead. The Series LF and LFSV Testing Machines are modular constructed and can be configured with a variety of grips and fixtures, extensometers, different software packages and other accessories to suits your specific testing needs. To meet the wide variety of testing needs, the LF (SV) is offered in different configurations. All options as: extended test space or distance between columns, other actuator strokes, protection device for operators safety, additional low force transducers a.s.o are available. The precision load cell, which is mounted on crosshead, is overload protect
Examples:
Type LF　 50 kN
Type LF 150 kN
Type LF 300 kN
Type LF 400 kN
