LTU750 Multi-function Paver, a multi-configurative, wide choices range and multifunctional paver, is manufactured by Xi’an Road Construction Machinery Co., Ltd.,  based on introducing the paving technique of DYNAPAC and absorbing the advanced operative technology of ABG423, VOGELE2500, and DYNAPAC F18/HOSE1500K, and being combined with our experience of design and manufacture of serial product and customers’ actual demands. The machine mainly used to pave the stabilized soil, and also can pave asphalt mixture at peculiar setup. The machine equipped with Rexroth Bosch Group hydraulic system, CUMMINS engine, advance auto leveling system and 7.5m/8.0m screed, which improved the construction reliability and ensured the paving compactness and smoothness. The multifunctional configuration making the machine can get the good construction quality whatever the material you used and whatever the paving width you set which within the stated range. With the reasonable price and practicability, this machine is the preferential choice for all kinds of standard highway construction.

  Performance and characteristics

Large range of paving width — can reach the requirements of multipurpose paving and multiplayer pavement.Multifunction configuration — bituminous concrete, stabilized soil or RCC can be use.Single/double tamper vibrator — user can choice single/double tamper vibrator and suitable vibration frequency depending on different pavement materials to reach the perfect compactness.Equipped with advanced electrical equipments —  the traveling system is controlled by REXROTH MC6 CCU which ensure the paver having a stable traveling speed at working and improve the smoothness and the homogeneity of compactness. And it can realize the fully auto control of auger, screed, vibration, auto leveling, and function pre-election and alarm.Adjustable screed — have the perfect functions of tamping, screeding, thickness adjustment, width adjustment/width reduction and frequency conversion/ amplitude modulation, and heating function is selective. There is enough integral rigidity even at the maximum assembling width.Simple operation and all-around vision —  cross- sliding operating panel, two seatStable power reserve — ample power reserve ensure the reliable power supply.Smooth traveling and steering — individual drive , CCU control.Homogeneous paving layer — four grade auger height adjustment, reasonable design of auger trough enable the applicability is wide and improve the segregation on the surface of paving layer and deepness.The screed board adopt abrasion resistance material — Sweden HARDOX400 special armor plate for a longer service life.Three-point supported engine installation — maximally eliminate the destructive effect to the engine which made by frame broken.Lengthening crawler design — 13 thrust wheels are be installed with different interval to reach the requirements of asymmetric load. The tractive force of the machine guaranteed that there is no slipping when paving at maximum width and thickness.Convenient maintenance — each rubbing point is lubricate with centralizing force feed lubrication and decentralizing force feed lubrication.Double stage hydraulic cooling circuit — due to the reasonable design of hydraulic system , the hydraulic oil temperature always keep in the safety range whatever the environment is.
