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.

Q:Technical maintenance of paver
1, daily maintenance (1) clean paver: remove the paver surface accumulation of mud sand and asphalt; remove the engine, hydraulic components and other components on the surface of dust and grease. Be careful not to pour dirt into the gas inlet and air filter. (2) inspect the nozzle, connecting pipe, air tank and switch of the heating system. (3) check the paver parts connecting and fastening, especially around the track beam and frame, screed, feeding device and the scraper conveyor device the connecting bolts are loose or broken, when necessary to tighten or replacement. (4) check and exclude the leakage of various parts. (5) check the engine oil, fuel, coolant and hydraulic oil quantity, and add new oil to the oil mark according to the regulation. (6) check whether the grease in the centralized lubrication unit is right or not. (7) check whether the blade of the screw distributor is cracked, if it should be replaced. (8) check whether the electrical plug is loose or not. 2, periodic technical maintenance (1), after running in 50h technical maintenance content before putting into use, paver should be 50h test run, otherwise, may not be put into use. The running in of 50h shall be carried out in accordance with the relevant regulations in the engine operation instructions. Running after the end of the test run, shall carry out technical maintenance according to the following contents: 1. The replacement of diesel engine: engine put old oil, then add new oil; after short-term operation, immediately check the oil level in the specified height.
Q:Machine parameters of paver ABG423
Volvo ABG asphalt paver engine performance parameters of Volvo D7 r/min SAE J1995 2000 rated output total power of 182 kW (247 metric HP) maximum paving width 13,0 m maximum paving thickness of 300 mm maximum spreading speed of 20,0 m/min 14,0 t (hopper capacity crawler type walking mechanism or wheel type) Tracked weight 17500 kg weight (with screed) 21590 kg
Q:Stabilized soil paver, what manufacturers produce better ah?
See how wide you want it to be. How thick is it?.QQ:17391841 Jiangsu Huatong power heavy industry (formerly Zhenjiang paver)
Q:What kind of machinery does the paver belong to and which department does the operation permit handle?.
Belong to the road construction machinery, operation certificate by the state administrative examination center designated, have special qualification unit organization examination release, general host factory have corresponding qualifications.
Q:Paver deviation of the law, how to solve?
From the analysis of the electronic control system, there are mainly 3 reasons for the deviation of the paver to one side:First, the steering potentiometer assembly is not good or medium drift. With the testing device of steering potentiometer and turn trimmer potentiometer, if it were in place, but the side turn signal, and the other side without turning signal, by resetting the steering potentiometer and turn trimmer potentiometer, can solve the problem.Two is the speed sensor damage. A speed sensor is detected by a detecting device. If the speed signal on one side is zero, the side speed sensor is damaged. Replace the side speed sensor at this time.Three is proportional solenoid valve, solenoid problems. If the electromagnetic valve solenoid individual differences exist, even if the starting current is the same, the walking pump output will be different, resulting in different speed of the walking motor. At this point, the starting current can be corrected by adjusting the starting current.
Q:What does the 31 paver mean when the oil pressure is too low?
If the engine oil pressure is normal, the engine runs normally. The oil pressure is low, the oil pump is worn seriously, or the pressure limiting valve is defective. The oil pressure is high, the oil pressure limiting valve is faulty or the oil circuit is blocked. Personal point of view, for reference only, for communication only.
Q:How to judge the malfunction of 423 paver traveling sensor?
The presence and development of sensors allow objects to sense sense of touch, taste, and smell, allowing the object to grow alive. Usually according to the basic cognitive function is divided into a heat sensitive element, a photosensitive element, gas sensor, force sensor, magnetic sensor, humidity sensor, acoustic sensor, radiation sensitive element, color sensitive components and sensors and ten kinds of flavor.
Q:31, 95 paver speed does not go down, what is the reason?
Is it possible to slow down when using emergency walking? Is the speed potentiometer defective?. Suggested inspection.
Q:Is the small concrete paver easy to use? Thank you
Model and parameter: product characteristic: single section adopts super universal connection, can adjust 5-10 arch. The leveling bottom plate can be assembled and disassembled freely, greatly reducing maintenance cost.
Q:What is the paver for comment
Paver leveling system is divided into horizontal slope leveling instrument, and longitudinal slope leveling instrument, is the machine in paver, automatic control instrument paving pavement thickness control, the former is cross slope, the latter control is (longitudinal slope pavement design height, that is, this is the height) the machine comes with the leveling instrument. There are also additional leveling instruments: balance beam
