1. Brief introduction of the main functions of the jack reaction frame

1. This jack reaction frame is mainly used for the detection of various specifications and types of jacks such as electro-hydraulic, penetrating, large tonnage, special large stroke, standard, and non-standard special types. It can also be used for concrete components and large workpieces. Compressive testing of various materials. It is a necessary test device for measurement and inspection, manufacturing enterprises, highway, construction, railway, bridge and other construction units, supervision companies, and quality inspection departments. The reaction frame is mainly composed of upper beam, column, base, nut, adjustment pad and so on.

2. Features of the jack counter-force frame host :

1)  Upper beam and base: adopt high-strength precision cast steel, which is machined to ensure parallelism, rigidity of the whole machine and stability of long-term use.

2)  Four- column structure host, the column is made of 45# high-quality carbon steel, after rough machining, quenching and tempering treatment, and then finishing forming.

3)  Column diameter: ￠100; ultimate bearing capacity: >500kN; deformation

4)  Adjustment pad: used to adjust the test space. Using 40Gr, heat treatment hardness is 40-45HRC .

3. Test standard: JJG621-2005 "Hydraulic Jack" Verification Regulations
