Servo Hydraulic Manhole Cover Compression Testing Machine

Model:TDYJG-600H

I. Product Overview

The Servo Hydraulic Manhole Cover Compression Testing Machine is a high-performance testing system designed for evaluating the load-bearing capacity, compressive strength, deformation behavior, and structural integrity of manhole covers, gully gratings, and related municipal access products.

It is engineered according to national and international standards such as:

EN 124

GB/T 23857-2009 Manhole Covers Standard

CJ/T 3012-1993 Cast Iron Manhole Covers

CJ/T 121-2000 Composite Resin Manhole Covers

CJ 889-2001 Steel Fiber Concrete Manhole Covers

The machine is widely used in quality inspection institutions, municipal engineering laboratories, construction material manufacturers, and research centers.

II. Testing Principle

The system applies controlled hydraulic force to simulate real-world traffic and load conditions. The testing process includes:

Static load compression test

Elastic deformation measurement

Permanent deformation evaluation

Optional cyclic loading test (for QT materials)

Destructive load testing (for HT materials)

The system ensures accurate simulation of service conditions for different material types.
