Cup-lock Mechanical Performance Testing Machine – High Precision Scaffolding Testing, Conforms to Multiple Standards

📌 Cup-lock Mechanical Performance Testing Machine Overview

The Scaffold Fitting Mechanical Performance Testing Machine consists of four vertical columns and two precision ball screws that fix the upper crossbeam and workbench. It uses an AC servo motor and drive, connected by synchronous toothed belts, to drive two pairs of high-precision, backlash-free ball screws that move the middle crossbeam up and down. The machine has reasonable structure, high rigidity, stable loading, and good stability. It is suitable for testing standards including “Steel Tube Scaffolding Couplers” GB15831-2006, “Safety Technical Code for Construction of Scaffolding Steel Tube Couplers” JGJ 130-2011, “Determination of Physical and Mechanical Properties of Ropes” GB/T8834-2016, “Safety Nets” GB5725-2009, and “Cup-lock Steel Tube Scaffolding” GB24911-2010.

⚙️ Key Features

• Automatic Stop: The crossbeam automatically stops when the sample breaks.
• Automatic Gear Shift: The range is automatically switched according to the load size to ensure measurement accuracy.
• Automatic Speed Change: The speed of the crossbeam can be automatically adjusted during the test based on a preset program, or manually adjusted.
• Automatic Calibration: The system can automatically calibrate the measurement accuracy.
• Automatic Data Saving: Test data and curves are automatically saved after the test ends.
• Process Control: The test process, measurement, display, and analysis are all completed by the computer.
• Batch Testing: After setting the parameters for one sample, the machine can sequentially test similar samples.
• Display Mode: Data and curves are dynamically displayed during the test process.
• Test Report: Reports can be generated and printed according to the user’s requested format.
• Limit Protection: Both program-controlled and mechanical limit protection are available.
• Overload Protection: The machine automatically stops if the load exceeds 3-5% of the maximum value in any range.
