Mine Car Connector On-board Horizontal Tension Machine

The WDL series electronic horizontal tension testing machine can perform tension tests on various mine car connectors and connecting chains. With suitable additional fixtures, it can also be used for the tensile testing of long samples such as metal materials, steel cables, power fittings, chains, and lifting straps. It is applicable to metal products, building structures, ships, and other fields. The microcomputer-controlled electronic horizontal tension testing machine utilizes our company's proven testing technology, incorporating a steel frame structure to convert vertical testing to horizontal testing. This design increases the tensile space (up to more than twenty meters, which vertical testing cannot achieve), meeting the testing requirements of large and full-size samples. The equipment is compact and suitable for installation on vehicles, fulfilling various customer needs.

The testing machine adopts a welded steel frame structure (according to customer requirements), driven by an AC servo motor to rotate the ball screw, with a load sensor for force measurement. The tensile space can be adjusted in stages according to the sample's specifications and length. The computer screen displays test force and curves, automatically processing data according to test method requirements. This machine is an ideal testing equipment for industries such as coal power enterprises, coal mine machinery, safety production inspection, and technical supervision. It is suitable for tensile and destructive testing of products such as electrical wires and cables, porcelain insulators, double hooks, steel strands, safety belts, waist ropes, foot buckles, etc., offering advantages including convenient operation, slow and steady loading, and strong load-bearing capacity.
