Product details
Inquiry
       The V-lock vertical connecting link mainly refers to the connecting link among the scraper chains of heavy-duty and super-heavy scraper conveyors in coal mines. It is developed and produced in strict accordance with the provisions of Q/AID01-2012 Technical Specifications for Mining Vertical Connecting Links, which is of advanced processing technology and high precision.
       This product is characterized by certain advanced nature and use reliability, and its strength and fatigue life are close to the level of connecting links with the same structure in the world. Its main technical properties are listed as follows:
        Advanced structure, reliable connection, easy assembly and disassembly;
        It can be used for the connection among mining round link chains and closing of the mining high-strength compact chain specified in MT/T929 for scraper conveyors.  it can also replace the vertical links in the flat chain, the combination chain and the F-class chain, which can only be vertically used;
        Select high-alloy steel rich in manganese, nickel, molybdenum, chromium and other elements as raw material, design meticulously and use precision machining , the original “differential heating treatment” process is adopted realizing better tensile properties and longer fatigue life of connecting links. 
 The main dimensions and breaking force of the product are as follows
