01 Purpose and function

This type of testing machine is mainly used for shear (fracture) tests of sand, rock itself, concrete itself, the contact surface of concrete and rock, and the weak structural surface of rock mass. The vertical load-deformation relationship curve, the horizontal
load-deformation relationship curve, and the vertical deformation-horizontal deformation relationship curve of the test piece  can be surveyed and mapped. It is a research and testing equipment for scientifific research units, universities and production and application units. Equipment reference standard

02 Product characteristics

1. It can realize multi-stage loading and maintenance, break judgement, break protection, automatic switching and other
functions.

2. It is smooth, stable and reliable when switching. The use of electro-hydraulic servo control technology, the perfect combination of control technology and energy storage technology of accumulators, and advanced algorithms solve the problem of sudden big jumps at the moment of shearing or sliding. Ensure fast and smooth switching and fast follow-up, making the back curve more perfect.

3. The reverse support sensor can be used to monitor the frictional force of the upper and lower rolling joint surface during shearing, so that the shear load measurement is more accurate.

4. It solves the problem of multi-scale conversion, and even multi-scale conversion can realize the conversion of 100mm-1100mm square samples. The loading load is from
2kN to 1300kN, and the large span can also be realized.
