Microcomputer Controlled Manhole Cover Compression Testing Machine

Product Features

This new-generation testing instrument from our factory delivers superior performance, easy installation and low failure rate. It is equipped with high-precision load cells and supports real-time detection with overload alarm function.

Product Overview

The microcomputer-controlled manhole cover compression testing machine adopts a microcomputer-controlled high-precision electro-hydraulic servo valve to drive a precision bidirectional hydraulic cylinder, realizing automatic multi-mode control of test force and displacement deformation to complete inspection and testing of manhole covers and drain grates of various materials and specifications. The main machine frame adopts two-column structure with top-mounted oil cylinder and a large 1500×1400mm workbench for convenient loading and unloading of manhole covers with good stability. Loading system adopts high-precision hydraulic servo valve to ensure high efficiency, low noise and fast system response; key components such as oil pumps and servo valves are imported.
