Maximum width of paving ： 4500mm
Maximum theoretic productivity ： 220t/h
2LTLZ45E asphalt paver is used for paving road, urban road, and plaza, square and so on, ideal equipment for construction companies.
The structure of this machine is compact, easily operated. It use advanced double sets of hydraulic stretching screed and auto level sensing device, so paving density and smoothness is high. The easily wearing parts use international advanced antifriction material, the reliability of machine is improved.
Drive system
The machine is driven by mechanical and hydraulic, flywheel is connected to transfer case, the front is connected to double pump, supplying power for mechanism below:
Traveling device
Conveyor and auger spreading device
Vibrating
Up and down of screed, turnover of hopper and action of cylinders
Traveling device
It is made up of transfer case, gear box with two grades, differential mechanism, semi-axle and chain drive. Traveling is driven by driven chain wheel.
Load mode
6 tyres, the front tyres are solid, the rear tyres are pneumatic
Steering
Steering mechanism use mode of bridge, center of bridge which is able to revolving is connected to center of frame, redirectors are fixed on the two ends of the axle, redirectors are revolved by hydraulic cylinder, and so solid tyre can be revolved corresponding angle.
Hopper
Hopper capacity is about 10 tons, hopper is turned by hydraulic cylinder to discharge material.
Roller
It is used to push the rear tyre of camion.
Conveyor
It is independently driven, clutch for conveyor is controlled by hydraulic cylinder, power is transferred by chain-wheel to drive scraper.
Electric system
It has 2 batteries, system voltage is 24V.
Cab
It used framework of steel tubes which are put together and equipped canopy.
Automatic level device
It is equipped one slope and one grade Automatic level device, used for automatic adjustment of slope and grade.
Main performance features:
▉ 55Kw China 4JR3AG7 engine with air cooling, strong power, reliable, start ability in low temperature environment
▇ Scraper and auger independent
Independent operation for L/R conveyor and auger, easy operation. Auger is stretched by mechanical to sure the spreading, auger blade is made of knock-down antifriction material, convenient replacement to ensure the life of auger.
▇ Driver has wide eyeshot, control panel can be moved to the L/R
All controlling components centralizes on the control panel, easy operation, control panel can be moved to the L/R according to demand. In this way, working intensity of operators can be lightened. Work efficiency and paving quality can be improved.
▇ Automatic leveling device ensures that smoothness of road
Automatic leveling device satisfied the grade criterion of freeway in the range of grade of 3mm/3m and slope of 2/1000, immediate control and convenient. It can avoid invalid fill of mixing material to lower cost of construction.
▇ Stretching screed, iron soleplate, conveyor soleplate use international advanced antifriction material
Iron plate can be sleeplessly stretched to change the width of paving layer conveniently. So the time of putting iron plate together is reduced.
▇ Advanced technical of electric system, all the controlled components connected to wire are in accordance with code so that the errors are immediately found and solved.
