Application and characteristics:

1. The test machine adopts microcomputer control and high accuracy electro-hydraulic servo valve, drive precision two-way hydraulic cylinder, a variety of automatic control mode of the test force, displacement, deformation, to complete the test a variety of materials, specifications, manhole covers, water grate cover, well grate.

 2. The host machine frame adopts two column structure, oil cylinder overhead; big working table 1500x1400mm; loading and unloading the manhole cover is very convenient, good stability.

 3. The loading system: uses the high accuracy hydraulic servo valve, ensure that the system is efficient, low noise, fast response; the key components of the oil pump, servo valve are imported.
