Mechanical loading and torque resistance testing are essential for evaluating the structural strength, mechanical stability, and durability of electrical enclosures, low-voltage switchgear assemblies, metering boxes, prefabricated substations, and other electrical equipment.
Depending on the applicable product standards and testing requirements, laboratories may need to perform various mechanical tests, including static load resistance tests, torque resistance tests, door mechanical strength tests, embedded base mechanical strength tests, and cabinet stiffness tests.
However, not every laboratory needs all these testing functions.
Some testing laboratories require a comprehensive testing system capable of covering multiple standards and test clauses, while others only need to perform one or two specific tests for a particular product.
At Sinuo, we understand that different laboratories have different testing objectives, specimen dimensions, and equipment budgets. Therefore, we provide flexible customized mechanical testing solutions, ranging from comprehensive multi-functional systems to dedicated single-function testing machines.
Our goal is to provide the testing functions you actually need, rather than requiring you to invest in an unnecessarily complicated system.
For laboratories that need to cover multiple mechanical testing requirements, Sinuo can provide an integrated mechanical loading and torque resistance test system.
Taking our IEC 61439-5 Comprehensive Torque Resistance Test System (Model SN2601A) as an example, the equipment integrates multiple loading mechanisms and adjustable specimen fixtures to perform different mechanical tests on electrical enclosures and related products.
The system can be configured to cover testing requirements from various standards and clauses, including:
IEC 61439-5: Clauses 10.2.101.2 (Static Load Test), 10.2.101.4 (Torque Resistance Verification Test), 10.2.101.6 (Door Mechanical Strength Test), and 10.2.101.9 (Mechanical Strength Test for Bases Intended to Be Embedded in the Ground).
GB/T 39752-2021: Clause 6.5.2.
EN IEC 61851-1 / IEC 61851-1: Relevant mechanical testing requirements, subject to the applicable edition and test scope.
GB/T 18663.1-2008: Clause 5.2.2, Cabinet Stiffness Testing.
GB/T 20641-2014: General requirements for empty enclosures.
GB 17467 and Q/GDW 11008: Relevant mechanical performance testing requirements.
By integrating different loading mechanisms into one platform, the system helps laboratories conduct multiple tests using a centralized equipment configuration.
Its main features include:
Two horizontal loading actuators and one vertical loading actuator.
Servo motor and electric cylinder-driven loading.
Adjustable force application positions to accommodate different specimen structures.
PLC intelligent control with touchscreen operation.
Automatic force acquisition and real-time force-time curve display.
Customizable fixtures, clamping blocks, and pressure plates.
This comprehensive solution is particularly suitable for third-party testing laboratories, certification organizations, and manufacturers that need to conduct multiple mechanical performance tests.
A comprehensive testing system is not always necessary.
If your laboratory only needs to perform a specific test according to one standard or a particular clause, Sinuo can also develop a dedicated testing machine designed specifically for that requirement.
For example:
Static Load Resistance Test: A dedicated loading system designed to apply the specified pressure or force to the top surface of an electrical enclosure.
Torque Resistance Test: A customized fixture and loading mechanism designed to apply the required horizontal forces to the specimen according to the applicable test procedure.
Door Mechanical Strength Test: A dedicated system designed to apply controlled forces at specified positions on enclosure doors.
Embedded Base Mechanical Strength Test: A customized loading arrangement for evaluating the mechanical strength of embedded enclosure bases.
Cabinet and Rack Stiffness Test: A specific loading system designed to evaluate enclosure deformation and structural stiffness under the required mechanical loads.
Instead of integrating every possible testing function, we can retain only the mechanisms, fixtures, and control functions required for your selected test.
Why choose a single-function solution?
Lower initial equipment investment compared with an equivalent comprehensive configuration.
Simplified mechanical structure and operation.
Fixtures and loading mechanisms designed specifically for the required test.
No need to pay for additional testing functions that your laboratory does not use.
A more focused equipment configuration for specific inspection or production applications.
For laboratories with clearly defined testing requirements, a dedicated single-function machine can be a practical and economical choice.
Besides the applicable standards and test clauses, specimen dimensions are another important factor in mechanical testing equipment design.
Electrical enclosures, metering boxes, cable distribution boxes, and prefabricated electrical cabinets can vary significantly in size, shape, material, and structural design.
A standard equipment configuration may not always accommodate every specimen.
To ensure proper specimen installation and accurate force application, Sinuo can customize the equipment according to your actual sample dimensions and structural characteristics.
Customization may include:
1. Specimen dimensions
The equipment frame, loading travel, and working platform can be designed according to the specimen's height, width, and depth.
2. Clamping and positioning fixtures
Customized clamping blocks, support structures, and positioning fixtures can be designed to securely hold different specimen types.
3. Loading positions and directions
The actuator arrangement, movement range, and force application positions can be adjusted according to the test requirements.
4. Loading force and control parameters
The force range, loading speed, holding time, and displacement monitoring functions can be configured based on the applicable test clauses.
5. Special specimen structures
For specimens with inclined roofs, gable roofs, special door structures, or other non-standard designs, corresponding fixtures and pressure plates can be developed.
Our engineering team will evaluate your specimen drawings, dimensions, and testing requirements before preparing the equipment configuration.
Both solutions have their advantages. The most suitable option depends on your laboratory's actual testing scope and future requirements.

If your laboratory needs to perform several mechanical tests or plans to expand its testing capabilities in the future, a comprehensive system may be more suitable.
If you only need to satisfy a specific testing requirement, a single-function customized machine may help reduce unnecessary equipment costs.
There is no need to invest in a full multi-functional system when only one specific testing function is required.
To help our engineering team evaluate your requirements and recommend the most suitable equipment configuration, we suggest providing the following information:
Applicable testing standard and clauses: Please specify the standard number, edition, and exact test clauses you need to comply with.
Specimen dimensions: Maximum and minimum specimen height, width, and depth.
Specimen information: Product type, material, structural characteristics, and preferably photographs or technical drawings.
Testing requirements: Required force, loading direction, loading position, holding time, and other relevant test parameters.
Equipment configuration preference: Whether you need a comprehensive multi-functional system or only a specific testing function.
Based on this information, we can evaluate the technical feasibility, design the appropriate fixtures and loading mechanisms, and provide a customized quotation.
As a professional manufacturer of testing equipment, Sinuo is committed to providing flexible testing solutions for electrical safety laboratories, certification bodies, inspection organizations, and manufacturers.
For mechanical loading and torque resistance testing, we do not limit our solutions to one fixed equipment configuration.
Whether you need a comprehensive IEC 61439-5 mechanical testing system covering multiple test clauses or a dedicated testing machine designed for a specific standard and specimen, our engineering team can develop a solution according to your actual requirements.
Tell us what you need to test, which standard you follow, and the dimensions of your specimens. We will help you find the most suitable testing solution while keeping your equipment investment under control.
