In order to comply with the implementation of the "Preventive Testing Regulations for Power Safety Tools" issued by the State Power Company, our company has developed the YH-20KN type power safety tool tensile testing machine (electronic force measuring machine) based on years of experience in safety tool testing. This product can complete the mechanical performance preventive test of all safety tools (safety belts, foot buckles, lifting plates, bamboo (wood) ladders, safety helmets) specified in the Regulations, and is suitable for mechanical testing of safety and climbing tools in industries such as power, telecommunications, and construction.
YH-20KN Electric Safety Tool Tensile Testing Machine (Electronic Force Measuring Machine)It consists of a vertical dual cylinder hydraulic bench, a safety helmet test bench, and a control cabinet including a microcomputer measurement and control system, with two operating systems: manual and automatic. In the automatic operating system, the name of the safety tool can be directly selected for preventive testing through keyboard and human-machine dialogue, and parameters can be set for mechanical performance testing of other materials. All test parameters, operation prompts, and working diagrams are displayed on the LCD screen, and test reports that meet the requirements of the regulations can be printed.

1. The mechanical performance testing machine for power safety tools developed and manufactured by our company meets the requirements of the "Preventive Testing Regulations for Power Safety Tools" (State Grid Corporation of China [2002] No. 777) and can complete various preventive mechanical performance tests in accordance with the regulations.
2. The test items are complete and can conduct mechanical performance tests on all electrical safety tools such as seat belts, foot buckles, bamboo (wood) ladders, lifting boards, and safety helmets.
3. Parameters can also be set to conduct mechanical performance tests on other soft materials (such as ropes) and hard materials (such as hoists and other lifting tools).
4. The testing process of this device is controlled by a microcomputer.
5. The instrument adopts Chinese character menu display and human-machine dialogue operation.
6. Load smoothly without overshoot, protecting the tested sample.
7. Can switch between manual/automatic operation, easy and accurate operation.
8. Has peak recording (commonly used for destructive tests such as safety helmets).
9. This series of safety tool mechanical performance testing machines consists of a microcomputer measurement and control system, a hydraulic loading system, and a safety helmet test bench.
