Excellent Performance

◇”JGM4221L track bulldozer is a large-sized multipurpose track-type one used for shoveling and moving soil, sandstone, and things like that. It is widely applied in various earthwork engineering projects such as earth-bulldozing in mine fields, capital construction works, road construction sites and port construction projects etc., as well as operation tasks of grading earth, shoveling soil and towing machines.

◇A diesel engine with turbocharger and fuel-feeding system of PT pump is adopted as the power supplier for the machine, with its characteristics of low fuel consumption, high power performance and large torque reserve.

◇The diesel engine matches very well with the hydraulic torque converter and the transmission system, making a wide rotational speed range for machine traveling in high efficiency. Output power can be achieved perfectly, with the control of shifting on the transmission gearbox.

◇A hydraulic drive system is adopted for the working device, with its characteristics of simple structure, flexibility and reliability.

◇The hydraulic-assisting mode is adopted in the control system, making the machine can be operated easily.

◇ A mode of hanging balance beam is adopted in the traveling system, making the machine works well in rugged areas.

◇Centralized pressure-testing technology is applied for inspecting and debugging failure easily; the highly generalization of wearing parts makes it easier to maintain overall machine.

◇ The sound-proofing, heat-proofing and vibration-absorbing cab provides efficient operation space and excellent operation vision for the driver. The cab is also equipped with a comfortable adjustable driver’s seat and air conditioner , together with an optional heater

◇Equipped with straight-tilting shovel as standard as well as U-shovel and angle shovel as options, all provided with well durable blade.

◇Optionally equipped with the ripper, (3-tooth or 1-tooth available),u-shovel, angle blade, air conditioning , heater, rear ripper, ROPS frame, forest cab，etc.”
