Design and innovative technologies allow Crawler bulldozer Liebherr PR 734 Litronic confidently deal with stratified soil movement or plan surfaces, and in the coal mines, these machines are used for loosening the overburden, site preparation for excavators, construction and cleaning of roads.
Guarantor ruthless performance "German" are particularly innovative solutions, implemented to create the engine-transmission unit and control system.The "heart" is a trademark bulldozer 6-cylinder diesel Liebherr D 936 L A6, which, when the working volume of 10.5 liters develops power of 204 hp.from.The engine is designed based on extreme conditions and by operating at reduced speeds for high reliability, efficiency and service life.The fuel injection system such as PLD (pump-injector tube), four valves per cylinder, turbocharged with charge air cooling and electronic workflow management provide sufficient reserve capacity to work in any situation.Friendliness of the motor to the environment complies with current environmental standards.
forced lubrication system and crankcase pressure increased depth provides confident operation of the engine when driving a bulldozer on the slopes slope of 45 °.An updated electronic Litronic control system in addition to the traditional function of protecting the motor from overload by automatically maintaining a balance between speed and traction controls for deviation from operating parameters and computer troubleshooting.
Infinitely variable hydrostatic transmission with separate independently driven caterpillars do not have a number of traditional bulldozers for many components such as the torque converter, transmission, differentials, clutches turn.With such a drive PR 734 Litronic equally confident work processes, moving both forward and in reverse.Electronic Litronic continuously adjusts the speed of rotation of the caterpillars (in the range from 0 to 11 km / h) and the torque optimizing traction depending on changing external loading.
machine is capable to move along a curved path and any unfold mestevokrug its geometric center.Heavy-duty final drives feature high endurance.A double gearbox seal with automatic control of tightness ensures their protection.Optimum control of the engine, hydraulic pump and hydraulic transmission reduces fuel consumption even under the most stressful conditions.Automatically activated when the car is stopped in the parking brakes final drives provide extra security.Support frame Liebherr PR 734 Litronic is made of a strong box-section profile that provides high structural strength in bending and torsion.The most important components are designed as cast parts.Modifications bulldozer, L, XL and LGP, different sizes of the undercarriage (as well as the length and width of caterpillar tracks), designed to work on surfaces with different load capacity (loose soil, rocks, marshland, etc.).All varieties of PR 734 Litronic can be fitted with dozer blade and ripper several types.Quick change adapter operating equipment reduces the time of installation and removal of dumps to several minutes.
Comfort and Ergonomics
Booth Liebherr PR 734 Litronic are the envy of many competitors.Its trump card - an elastic suspension, an impressive internal volume, an impressive area of tinted glass, sliding side windows, windshield wipers effective and powerful outdoor lighting fixtures.Built-in safety cage provides protection in the event of a rollover (standard ROPS) and falling objects (standard FOPS).Due to the enhanced noise insulation in the cabin does not exceed 78 dB (A), which is considerably lower than the legal requirements dictate.Place captivates an exemplary operator ergonomics and comfort, which will undoubtedly create the conditions for productive work.A comfortable chair with individual suspension, belts, lots of settings provisions cushion and backrest and adjustable headrest and armrests will be impressed by any user.All test instruments and controls are located in the zone of visibility of the best and easy to reach.In the combined instrument panel are arranged in a logical sequence, analogue displays and security devices, as well as liquid crystal display, which displays the set of diagnostic parameters and performance of the main systems of a bulldozer.With the help of a joystick, the operator can easily control the forward and reverse, as well as a curved motion, including turning on the spot.The other joystick is used to control the working equipment (blade and ripper).A comfortable interior climate provide a high-performance ventilation and heating and air conditioning if necessary.It is also impossible not to mention high-quality plastic used in interior decoration, and a roomy glove box with an electrical connector 12 V to connect the mini-fridge.For the convenience of servicing bulldozer cab using the integrated manual hydraulic jack can be folded back at an angle of 40 '.For the same reason all the points of control systems of the engine are located on one side.
