Technical Specifications
Drive System
The whole machine is driven mechanically-hydraulically. Flywheel end of engine is connected with transfer case. The front of engine is connected with split flow pumps to supply power to the components as follows:
1. crawler traveling devices
2. conveyor and auger feeder
3. tamper and vibrating device
4. hopper folded in & out, screed up & down and other cylinders action
Traveling Device
It consists of gear box, transfer case, traveling clutch and chain transmission.The driven chain wheel activates the crawler.
Weight Bearing Mode
There are two crawlers. Crawler patches are configured with rubber. Each crawler ground touch area is 2672×300mm.
Steering
The traveling clutch is operated by hydraulic cylinder. The brake can make the machine turn at original place.
Hopper
The capacity is 10 tons and operated by hydraulic cylinder for entire discharge.
Push Roller
The roller can swing to push the truck rear wheels.
Conveyor
Left and right conveyor is independently driven. Clutch is controlled by hydraulic cylinder and driven by sprockets, and revolve the feeder.
Electrical System
The system is equipped with two batteries. The voltage is 24V.
Canopy
It is consisted of steel tube and cloth.
Automatic Leveling Sensors
It has two longitudinal and one transverse leveling units, used for automatic adjustment of slope and grade.
Working Devices
Double hydraulic extension screed
1.Screed basic width 2500mm
Max. Paving width 4500mm
arch of max paving 0--4%
2.Vibration frequency 0~50 Hz
3. Extended screed 0.75mm 2 segments
LTL45C Paving material application

Main Performance
1. Fitted with 55KW Quancai engine from Anhui in China, strong and reliable power , can be started in low temperature condition.
2.Independent left & right conveyor and augers feederIndependent operation for L/R conveyor and sauger feeder, easy operation. auger feeder is extended mechanically. auger feeder blade is made of wearable material, convenient replacement to ensure screw life.
3. Wide Eyeshot and Removable Operation PlatformAll the control elements centralize on operation platform for easy operation. Improve efficiency to guarantee pavement quality.
4. Auto Leveling Units to offer Reliability for Road Smoothness
The machine is equipped with automatic leveling probes, which reaches the demand of high-grade road smoothness within 3mm/3m. It controls in time, convenient and intuitionistic. It can prevent the asphalt from valid filling to reduce construction cost.
5. Extended ScreedScreed can be stepless extended to meet different paving status, save the time of adjusting width of screed.
6. Strong and durable crawler device, with strong traction force
Use floating and height adjustable structure for thrust wheel of crawler, ensuring stable travel, so the paving planeness cannot be affected by unsmooth road base. The crawler device is composed by forever lubricated thrust wheel and rubber crawler plates is durable with good adhesive force and not easy to slip and protect roads.
7.Fuel oil electrical cleaning system makes convenient clean and reduce work intensity.
8.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.
Key Parts
1.Engine: China famous brand, Quancai engine in Anhui, China,water cooled engine.
2.Hydraulic pump & Hydraulic vibrating motor made in China,
3. Control valves , Centralized lubrication & Automatic leveling device uses Chinese famous brand
4. High and low pressure directional control valve from Italy Atos corporation.
