Mine car connecting parts vehicle-mounted horizontal tensile machine

The WDL series electronic horizontal tensile testing machine can perform tensile tests on various mine car connectors and connecting chains, with the addition of appropriate auxiliary tools. It can also be used to stretch long specimens such as various metal materials, steel ropes, power fittings, chains, lifting belts, etc. It can be used in metal products, building structures, ships and other fields.The microcomputer-controlled electronic horizontal tensile testing machine adopts our company's mature testing machine technology and adds a steel frame structure to convert the vertical test into a horizontal test. This increases the tensile space (can be increased to more than 20 meters, which is impossible for vertical testing), and meets the needs of testing large specimens and full-size specimens. This equipment is exquisite and suitable for placement on the vehicle to meet various needs of customers.

The testing machine adopts the overall steel plate welded frame structure (according to customer needs). The AC servo motor drives the ball screw, and the load sensor measures the force. The stretching space can be adjusted step by step according to the length of the sample specification. The computer screen displays the test force and test curve, and automatically processes the test data according to the requirements of the test method. This machine isIt is an ideal inspection equipment for coal and electricity enterprises, coal mine machinery and equipment, safety production inspection institutes, technical supervision and other industries. It is suitable for tensile load and damage tests of wires and cables, porcelain bottles, double hooks, steel strands, seat belts, waist ropes, foot buckles and other products. It requires flexible and convenient operation, slow and steady loading, and strong body carrying capacity.
