12th January, MAXTECH's 4T@30M telescopic crane successfully completed on - site tests. The purpose of these tests was to comprehensively examine the performance and safety of the crane, covering three key aspects: 110% overload protection test, 120% SWL static load test, and post - trial inspection. The test results were remarkable, fully demonstrating the excellent quality of the marine crane.
During the 110% overload protection test, technicians gradually increased the lifting weight until it exceeded the rated load.
The content of test including:
1. Rated load test: 1XSWL, heeling 5°，Trim 2° to lift the load, lifting, rotating, falling, braking action a loop, for at least 2 times.
2. Set pressure of the relief valve. Adjust weight of the weight, about 100% load weight 1.1 times, carry put test, cannot lift heavy weight.
3.Holds weight up from ground, hanging 5 minutes. As a result of the test there should be no evidence of permanent deformation and other damages.
The ship crane's overload protection device responded promptly, precisely restricting the lifting action and ensuring the safety of the equipment under extreme conditions, effectively avoiding potential risks caused by overloading.
The 120% SWL static load test was also successfully completed. The 4T@30M electrical hydraulic crane remained stationary for holding weight up from ground, hanging 5 minutes. During this period, there were no obvious deformations or damages to the structural components, and all connection parts were stable and reliable, fully verifying the strength and stability of the crane's structure to meet the high - intensity requirements in actual operations.
The post - trial inspection was meticulous. The main content was to measure the thermal insulation resistance of the motor. Finally, it covered all aspects of the crane, including mechanical components, electrical systems, and hydraulic devices. Technicians used professional tools and equipment to conduct a comprehensive inspection of key parts, ensuring that the equipment was operating well and all parameters met the design standards.
The success of this on - site test not only laid a solid foundation for the market promotion of MAXTECH's 4T@30M telescopic boom ship deck crane but also further consolidated MAXTECH's leading technical position in the crane manufacturing field. This product is expected to provide efficient and reliable lifting solutions for various engineering construction projects, helping the industry to reach new heights.
