Technical Features

-The machine is a four-column frame structure, and the oil cylinder is a down-mounted type, connected to the base by a nut. 

The piston moves the piston up and down through the transmission of oil pressure and applies pressure. The piston is connected to

the upper and lower disks by connecting load sensors to transmit the force value to the computer.

-Servo hydraulic source: low-noise high-pressure plunger pump.

-Adopts hydraulic loading, electronic force measurement, digital display of test force, test force peak value, test speed, and

automatic data processing.

-The hydraulic system is mainly controlled by the oil return valve handle, which is easy to operate and safe. The height of the

control part and the indication part are appropriate, which is convenient for the tester to operate and observe.

-Equipped with a micro printer, which can print out the experimental results. Completion of the pressure test of various materials

and specifications of manhole covers.

-Adopts a two-column structure, and the oil cylinder is placed on top; a large worktable is 1200x1400mm; the manhole cover can

be easily loaded and unloaded, and the stability is good.

-Safety protection, with automatic overload protection, overcurrent protection, overvoltage protection, overspeed protection and

other functions.
