Tiltrotator testing is the process of evaluating the performance, functionality, and safety of a tiltrotator attachment used in construction equipment, such as excavators. A tiltrotator is a hydraulic attachment that allows the operator to rotate and tilt the bucket or other attachments, providing increased flexibility and efficiency in various construction tasks.
An excavator attachment is a tool or accessory that can be attached to an excavator to enhance its functionality and performance. These attachments are designed to perform specific tasks and can be easily attached and detached from the excavator, depending on the job requirements. Some common excavator attachments include:

AC voltage withstand test transformer Note 1, to do high-pressure test, must be 2 or more than 2 people to participate, and clear division of labor, clear contact between each other. There are special people to monitor the safety of the site and observe the test status of the test sample;
2. The transformer and control box should have reliable grounding;
3. During the test, the boosting speed must not be too fast, and sudden full-voltage power-on or power-off must not be allowed.
4. In the process of step-up or withstanding voltage test, if any of the following abnormalities are found, it should be immediately depressurized, and cut off the power supply, stop the test, and check the cause of the AC voltage withstand test transformer before doing the test. 1 The voltage meter pointer swings a lot; 2 The smell of burning insulation and smoke are found; 3 There is abnormal sound in the tested product.
5. During the test, if the sample is short-circuited or breakdown, the over-current relay in the control box will work. At this time, the regulator will be returned to zero and the sample can be taken out after the power is cut off.
6. When conducting capacitance test or DC high-pressure leakage test, after the test is completed, lower the voltage regulator to zero and cut off the power. Then, discharge the high-voltage terminal of the test sample or capacitor to the ground with the discharge rod to avoid The potential remaining in the capacitor is at risk of electric shock.
During tiltrotator testing, various aspects are assessed, including:
1. Rotation and tilt capabilities: The attachment's ability to rotate and tilt smoothly and accurately is evaluated. This involves testing the range of motion, speed, and precision of the tiltrotator.
2. Load capacity: The attachment's load-bearing capacity is tested to ensure it can handle the specified weight limits. This involves subjecting the tiltrotator to various loads and evaluating its performance under different conditions.
3. Hydraulic system performance: The hydraulic system responsible for controlling the tiltrotator's movements is tested for efficiency and reliability. This includes assessing the responsiveness of the hydraulic controls and evaluating any potential leaks or malfunctions.
4. Safety features: The tiltrotator's safety features, such as overload protection, emergency stop mechanisms, and locking mechanisms, are tested to ensure they function properly and provide adequate protection for the operator and surrounding personnel.
5. Durability and endurance: The attachment is subjected to rigorous testing to evaluate its durability and endurance under real-world construction conditions. This involves simulating various work scenarios and assessing the tiltrotator's ability to withstand wear, tear, and potential damage.
6. Compatibility and integration: Tiltrotators are designed to be compatible with specific excavators or other construction equipment. Testing involves verifying the attachment's compatibility with the designated machinery and assessing its integration and ease of installation.
Tiltrotator testing is crucial to ensure the attachment meets performance standards, adheres to safety regulations, and functions reliably in construction applications. It helps identify any design flaws, manufacturing defects, or operational issues that need to be addressed before the tiltrotator is used in the field.
