Jinan Chenda 2000kN microcomputer controlled electro-hydraulic servo universal testing machine is suitable for tensile mechanical testing of heavy-duty lifting equipment such as lifting hooks, rings, chains, and shackles, as well as high-strength steel structural components. It is suitable for self inspection, process optimization, and type testing of lifting hook production enterprises.
The equipment is equipped with a servo hydraulic closed-loop control system, which can load smoothly and controllably, simulate the actual lifting force state of the hook, fully record the elastic deformation, plastic deformation, and ultimate fracture process of the hook, and automatically calculate core parameters such as load deformation, yield load, tensile limit, and elongation after fracture. The equipment can be matched with various customized special fixtures. After clamping, the workpiece is placed in the center of the force, reducing eccentric loads, fitting the real working conditions, and ensuring the stability and standardization of the test.
The overall rigidity of the machine body is sufficient, and the pressure fluctuation during large tonnage testing is small. At the same time, multiple protective devices such as overload, over displacement, and abnormal oil pressure shutdown are equipped to enhance the safety of heavy-duty fracture testing operations. The experiment runs automatically throughout the entire process, with supporting measurement and control software recording tension and displacement change curves in real time. After the experiment is completed, various mechanical indicators are automatically calculated, and traceable detection reports are generated. The data can be archived and retained for a long time, suitable for use in enterprise quality inspection filing, customer factory inspection, project bidding and other scenarios.
In response to the quality inspection requirements for lifting hooks, this machine can complete standardized testing projects such as static load voltage stabilization testing, permanent deformation determination, and ultimate fracture testing. Enterprises can identify differences in raw material quality, heat treatment, and forging processes by comparing multiple sets of sample test data, continuously optimize production processes, stabilize batch product quality, control the quality of lifting components, and reduce safety hazards such as heavy load deformation, fracture, and falling.
The equipment has a wide range of applications. In addition to various types of lifting hooks, it can also meet the mechanical performance testing of various heavy metal structural components. It is widely used in quality inspection laboratories in industries such as lifting equipment manufacturing, engineering machinery parts, and steel structure processing. Jinan Chenda supports customers to bring samples to the factory for testing, customize tooling according to their needs, and provide equipment installation, debugging, and professional after-sales technical services for users.
