SD52-5 crawler bulldozer adopts the modular structure and numerous advanced energy-saving and noise-reduction technologies, featuring strong power and high reliability. This product can adapt to more severe operation environments and is an essential large mechanical equipment for earth-moving and stratum stripping for the projects such as mining and water conservancy construction.

  1.The high reliability power shift transmission and the planetary gear final drive feature high power transmission efficiency and high durability and productivity.

  2.The cooling system fan speed is automatically regulated depending on the engine coolant temperature to shorten the time required for the water and oil temperatures to reach best temperature zone, reduce the energy consumption of cooling system, save more fuel, and lower the working noise of vehicle.

  3.The high pressure hydraulic system effectively reduces the volumes of hydraulic units, saves the usage quantity of hydraulic oil, and eases the maintenances.

  4.The water-proof connectors, good circuit protection, lifelong maintenance-free Optima battery, and advanced engine malfunction diagnostic technology for the whole machine eliminate the troubles arising from the malfunction of electric system.

  5.The air suspension traveling system always keeps the close contact between track rollers and tracks to increase the ground area of tracks and improve the traction force of the machine.
