JAW-1500KN lower hydrau-cylinder computerized manhole cover compression testing machine

1. Introduction of testing machine

The manhole cover compression testing machine can be used to test the compression properties( permanent set, load bearing capacity) of cast iron manhole cover, composite material manhole cover, and steel reinforced concrete.

The manhole cover compression testing machine adopts computerizing, high precision electro-hydraulic servo valve to drive precise hydraulic cylinder and then realize the auto control to the test force, displacement, and deformation, etc.

the Manhole Cover Testing Machine, designed to ensure the strength of manhole covers used in various infrastructure projects. This advanced machine is essential for manhole cover compression testing, allowing precise evaluation of the load-bearing capacity and structural integrity of manhole covers under extreme pressure. The load testing for manhole covers helps simulate real-world conditions, ensuring they can withstand heavy traffic and harsh environments.

This manhole cover strength testing machine offers comprehensive assessments of static load, ensuring compliance with industry standards. The manhole cover pressure test equipment accurately measures the pressure resistance. This machine is a critical tool for manhole cover quality control, ensuring that only the highest quality products reach the market.
