In urban roads, municipal pipelines, residential areas, and various public places, manhole covers are an important component of infrastructure, and their bearing capacity and compressive performance are directly related to pedestrian safety and vehicle traffic safety. With the acceleration of urbanization, the demand for quality testing of various cast iron manhole covers, steel fiber reinforced concrete manhole covers, recycled resin composite manhole covers, and water grate covers is increasing day by day. Jinan Xinguang Testing Machine Manufacturing Co., Ltd.'s microcomputer controlled manhole cover pressure testing machine series provides high-precision, fully automatic testing solutions for factory inspection, quality inspection agency supervision and inspection, and engineering acceptance of manhole cover production enterprises.
As a pavement facility that can withstand repeated vehicle crushing, the compressive strength and residual deformation of manhole covers are the core indicators for measuring product quality. The traditional detection method has problems such as unstable loading control, inaccurate data recording, and excessive manual intervention during the experimental process. The Xinguang microcomputer controlled manhole cover pressure testing machine strictly follows national and industry standards in design, adopts advanced electro-hydraulic servo control technology, and has the following outstanding advantages:
1、 Dual tonnage specifications, covering the entire range of testing requirements
2、 High rigidity host structure ensures test safety
3、 Flexible host layout, easy and efficient operation
4、 High precision measurement and control system, fully automatic closed-loop control
5、 Specialized testing software, one click completion of experiments
6、 Multiple security protection mechanisms
The Xin Guang microcomputer controlled manhole cover pressure testing machine complies with the following national standards and industry specifications:
-GB/T23858-2009 "Inspection manhole covers"
-CJ/T511-2017 "Cast Iron Inspection Manhole Cover"
-CJ/T121-2000 "Inspection manhole covers for recycled resin composite materials"
-JC/T889-2016 "Steel Fiber Reinforced Concrete Inspection Manhole Cover"
-CJ/T211-2005 "Inspection manhole covers for polymer based composite materials"
-CJ/T3012-1993 "Cast Iron Inspection Manhole Cover"
-GB/T2611-2022 General Technical Requirements for Testing Machines
-EN124 (European standard, optional)
The product is widely used in the following fields:
-Production enterprises of manhole covers: Factory inspection and type testing of cast iron manhole covers, steel fiber reinforced concrete manhole covers, and composite material manhole covers
-Municipal engineering quality inspection agency: on-site acceptance and supervision sampling of road manhole covers
-National Building Materials Testing Center: Quality Certification and Supervision Inspection of Manhole Cover Products
-Research Institute: Development, Validation, and Performance Study of New Well Cover Materials
-Urban management department: Sampling inspection and safety assessment of manhole covers in use
