Main features:
Computer Control manhole cover compression testing Machine, a high-performance Testing solution designed for evaluating the load-bearing capacity and mechanical properties of various manhole covers. The machine is widely used for compression and flexural strength Tests of cast iron, recycled resin composite, and steel fiber concrete manhole covers. It complies with GT/T2611 General Technical Requirements for Testing machines, JIG139 Tension, Compression and Energy Testing Machines, as well as professional standards including CJ/T3012-1993, CJ/T121-2000, and JC889-2001.
Equipped with a microcomputer-based electro-hydraulic servo control system, the machine provides automatic loading, accurate force measurement, and stable test performance. Its high-rigidity main frame, upward-positioned loading cylinder, precision oil system, and ball-jointed compression mechanism ensure reliable testing results and long-term operation.
The machine features a maximum test force of 1000 kN, an effective test space of 1200 mm × 1200 mm, a loading speed range of 0.1–25 kN/s, and deformation measurement accuracy of 0.01 mm. Computer software enables real-time curve recording, automatic data processing, report generation, and programmable closed-loop control for cyclic loading tests.
