The static load sleeper testing machine is a device for testing the static load crack resistance test of concrete sleepers (Type I sleepers, Type II sleepers, Type III sleepers, fork sleepers, bridge sleepers, wide sleepers, etc.). The product conforms to the standard of TB/T1879-2002 \"Prestressed Concrete Pillow Static Load Cracking Test Method\".
Features:
The force measurement of this machine adopts high-precision load sensor, microcomputer program control, electro-hydraulic proportional hydraulic loading system and other technologies.
Use the positioning ruler (self-provided) to adjust the position of the sleeper so that the load center coincides with the center of the pressure plate.
According to the set working procedure, the piston moves freely.
Equipped with three high-precision spoke sensors to ensure accurate data of three separate pressure points, and equipped with special LED crack observation lights. In order to facilitate the sleeper test of foreign standards, the fulcrum can be adjusted.
The loading process is adjusted with the variable structure PID control algorithm, the constant speed control error is ≤5%, and the pressure holding control error is ≤0.5%. Loading speed Uniform loading.
The static load point can be set arbitrarily, and the data result report is automatically printed.
