Fully automatic rock point load bending creep test system
Instrument composition
This instrument is a column mounted structure, which consists of a base, gearbox, column, bracket, motor, controller, force sensing, software, etc. The power is transmitted to the gearbox through an electro-hydraulic servo, and the gearbox passes through a complete set of transmission mechanisms to drive the screw rod to drive the lower head to obtain the required upward speed, thus completing the test requirements.
