  • Benefits of wheel block system

    • For crane manufacturers, it provides a ready made solutions
    • With closer ranges of diameter with the number of variables in an organized way, which suits for specific applications in a cost effective manner
    • Easy for assembly and disassembly
    • Time to market is very quick
    • Grey iron housings ensure the robustness of the product
    • Less maintenance , suitable for harsh environment and increased service life
    • Wheel block can be replaced easily with less effort
    • Flange wear indicator ensures preventive maintenance without risk
    • Gearbox mounting flange & torque arm mounting which reduces the peak load as a result of travel wheel slip torque.
    • The variants are designed to suit the applications in a cost-effective manner

  • Wheel Block Connections

    • 01. Wheel Block System — Top Connection

      • Top side of the wheel block is directly bolted to the end carriage with the help of studs.
      • Mounting flange is bolted at one side of the wheel block to support the gearbox

    • 02. Wheel Block System — Side Connection

      • One side of wheel block is mounted to the end carriage with sleeve & flange washer
      • Mounting flange is bolted at one side of the structural plate to support the gear box

    • 03. Wheel Block System — Pin Connection

      • A pin is used to mount the wheel block with the plates on two sides
      • Gear box is mounted with help of triangle bracket and a torque arm

    • 04. Wheel Block System — End Connection

      • Similar to pin connection, wheel block is inserted into the hollow section and a pin is used to connect the wheel block with the end carriage
      • Gear box is mounted with the help of triangle bracket and a torque arm
