Digital Manhole Pressure Testing Machine , High Rigidity Structure
This machine is based on CJ/T3012-1993 "cast iron inspection
manhole cover", CJ/T121-2000 "recycled resin composite inspection
manhole cover" and JC889-2001 "steel fiber concrete inspection
manhole cover", GB/T 23857-2009 "inspection manhole cover", etc.
Designed by industry or national standards for testing the bearing
capacity and deformation of the manhole cover. Its structural
performance meets the requirements of the test specification.
Main technical parameters:

|Loading speed adjustment range||0.1 ~ 25KN / s (manual stepless speed regulation)|
|Deformation measurement range||0-20mm|
|Deformation measurement resolution||0.01mm|
|Load indication accuracy||0.1KN|
|Control mode||manual / electro-hydraulic servo speed.|
|Loading media||46#/68# anti-wear hydraulic oil|
|Host size||1200mm × 1400mm × 1500mm (length × width × height)|
1. The main machine adopts high rigidity structure to ensure the
safety during the test.
2. The loading cylinder is placed below, and the height of the
table is 300mm, which is convenient for taking and placing the
manhole cover test piece.
3. The ball joint is connected between the rigid block and the
push-out end of the piston to ensure the authenticity of the
measured bearing capacity.
4. The special sealing material is used between the cylinder and
the piston to achieve high sealing, low friction and long life.
5. The use of professional test oil pump motor unit, low noise and
6. Use ultra-fine oil filter to ensure the cleanness of the oil
circuit system to ensure long-term operation of the control
7. The digital display shows that the current force value, peak
value, etc. are displayed in real time.
