※All parts of the brake shown in the figure are of standard German universal design, and the market parts are interchangeable.
※Different types of brakes only have different widths of brake shoes and friction linings.
※After the friction plate is riveted, it is processed by cylindrical grinding. After the axle is assembled, the initial braking contact area with the brake drum is ≥90%.
※The high-frequency induction treatment at the double openings of the brake shoe has high hardness and strong wear resistance.
※The buckle type tension spring design is convenient for the disassembly and installation of the brake shoe.
※The outer circle of the roller is processed by centerless grinding after high frequency, the surface is smooth, and the braking and return resistance is small.
