1. introduction
LAW series horizontal tensile testing machine is made up of loading frame, fixed crossbeam, moving crossbeam, loading system and testing software. Its horizontal loading frame significantly extend the tensile space to be more than 10 meters for big and long test specimens.
The horizontal tensile testing machine is mainly used to measure the static tensile properties of materials and spare parts such as metal, steel chain, belt, wire, etc.
The horizontal tensile testing machine adopts steel plate welding frame, loading by piston cylinder, hydraulic auto clamping, force measuring by load cell and can adjust the tensile space according to length of the specimen at a certain length.
2. features
Adopting digital phase locked loop position pulse control mode, no null shift, no imbalance
Adopting high precision ball screw to load, stable, long service time and save energy
Software protection functions for over load, over limit position
Simple, reliable and power software operating interface
Open data structure, clients can use the test data (data for test results or process data) freely, very suitable for research and education.
Its test report can be load to Excel, Word format for later use.
Low noise, no oil pollution, very convenient
Full digital computer control closed loop material testing software can switch among closed loop control for displacement, stress, deformation freely to meet with different test requirements.
Hand control box can adjust PID parameters, one button for test and safe switch for any emergency.
