United Test make Universal Testing Machines are known for their long lasting trouble-free performance and highest quality material used in the manufacturing process. The Hydraulic universal testing machine can perform tension, compression, flexure/bending and shearing test for kinds of specimens. Suitable for metal and nonmetal material, such as iron, steel, steel bar, rebar, cement, concrete, steel rod and so on.
Specially design for production, research, student training and industrial laboratory. Available in wide range of loadframe capacities (300kN to 2000kN)/(10Ton to 200Ton) and with combination of control panels (Digital, Computerised) makes United Test product range suitable for every customer requirement.
Load weighing system meets or exceeds the requirements of the following standards: ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO 7500-1.
Main features:
1), Computer controlled hydraulic servo operate loading model, double working space, tensile test at upside of crosshead, compression and bending test between working bench and crosshead;
2), It adopts the hydraulic pressure to drive the cylinder, so loading on the specimen to perform the test. Hydraulic station supplies super and stable pressure to the system; the soundproof insulation can reduce the noise level of the power pack to 75 dB (A), with lower noise, tiny energy consuming and lower heat.
3), Unique screw gap eliminating structure can guarantee the continuity of the test;
Total six columns structure, four column and two leading screw to make the machine more stable and life long working.
4), Independent hydraulic clamping structure can guarantee the reliability of the system; it will not hurt person for falling specimen and ensure the safety of operator;
5), Limitation and electrical protection system can ensure the security of using;
6), The load frame adopts oil cylinder bottom type structure, hydraulic load, hydraulic clamping specimen;
7), Servo valve can control the speed arbitrarily through the software. It can carry out loading, unloading and oil quick feedback function (i.e. the cylinder come back to its original position after the test);
8), Crosshead (the middle beam) movement is by mean of motor, chain at the bottom of loadframe, driven leading screw to make crosshead up and down.
