What Is a Manhole Cover Tester?
The Manhole Cover Tester is designed to determine the mechanical load resistance of concrete manhole covers, inspection chambers and similar infrastructure components. The machine reproduces high service loads under controlled laboratory conditions.
The system can be used with plain concrete, steel-fibre-reinforced concrete and reinforced concrete specimens. Its high-capacity loading frame also supports the evaluation of large and heavy infrastructure products.
The LT-U1100 provides a maximum testing capacity of 1000 kN.
Rigid Four-Column Test Frame
The machine uses a four-column rigid frame to maintain stability during high-load testing.
A strong frame is particularly important when testing large manhole covers and inspection chamber components. It helps reduce unwanted movement during loading and supports consistent transfer of force to the specimen.
The rigid structure also provides a durable testing platform for intensive laboratory use.
Automatic and Programmable Loading
The Manhole Cover Testing Machine includes an automatic hydraulic power unit designed to control the loading sequence.
The operator can perform programmed test cycles according to the selected test procedure. This improves repeatability because the loading sequence does not depend entirely on manual control.
The system can also apply the required test load several times consecutively when the testing procedure requires repeated loading.
Constant Load Holding
Certain test procedures require the applied force to remain constant for a specific period.
The control system can maintain the selected load for up to 120 seconds. This allows the operator to observe specimen behaviour and deformation while the required force remains applied.
Controlled load holding is particularly useful when checking the mechanical response of manhole covers and similar heavy-duty infrastructure products.
Three-Piston Loading System
The equipment uses a three-piston loading mechanism to support balanced transfer of force to the test specimen.
A special spring mechanism assists the initial contact between the loading system and the specimen. This helps establish the correct starting position before the main load is applied.
Balanced force transfer is important when testing large components because uneven loading may affect the mechanical response of the specimen.
Testing of Concrete Infrastructure Components
The system is suitable for manufacturers of manhole covers, precast concrete producers, infrastructure laboratories, universities and quality-control centres.
Concrete manhole covers and inspection chamber components may experience significant traffic and service loads during their operating life. Laboratory testing allows manufacturers to evaluate these products under repeatable conditions before installation.
The 1000 kN capacity provides sufficient force for heavy-duty testing applications.
Testing According to EN 124 Series
The EN 124 series covers gully tops and manhole tops used in vehicular and pedestrian areas and includes different requirements according to material and product type.
The product also references EN 1917, which covers concrete manholes and inspection chambers.
The Manhole Cover Testing Machine supports mechanical loading procedures associated with these types of infrastructure products when configured and operated according to the applicable test method.
Reliable 1000 kN Manhole Cover Testing
The Manhole Cover Tester combines a rigid four-column frame, 1000 kN loading capacity, automatic control and programmable loading cycles.
Its repeated-load capability and constant-load holding function allow laboratories to reproduce demanding test sequences in a controlled manner.
As a result, the LT-U1100 provides a professional solution for evaluating the mechanical resistance of manhole covers, inspection chambers and related concrete infrastructure components according to the relevant testing requirements.
