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 minefields, capital construction works, road construction sites and port construction
projects, etc., as well as operational 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 with 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 high
generalization of wearing parts makes it easier to maintain the overall machine.
◇ The sound-proofing, heat-proofing, and vibration-absorbing cab provide 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 the straight-tilting shovel as standard as well as U-shovel and angle shovel as options, all
provided with the 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.
