1220MAXI-PAV SLIPFORM CONCRETE PAVER, 1. Paving Width:asphalt 4250-8000mm;, 2.Paving Thickness: 350mm; - details see: https://www.machineto.com/1220maxi-pav-slipform-concrete-paver-10118291

1220MAXI-PAV SLIPFORM CONCRETE PAVER

The technology of 1220MAXI-PAV slipform is imported from American Pro-Hoff Company. Using of this paver can greatly improve paving quality and speed; therefore, it is widely used to meet the need of concrete pavement construction in our country.

All the components are driven by hydraulic circuits, and the machine travels with two crawlers. Moreover, the automatic driving and leveling control systems are equipped in this machine. When working, the paver can accomplish paving, scraping, vibrating, shaking extruding, shaping at one time. Meanwhile, the road edge can be paved with the edge mould, and the reinforce steel bars can be inserted in the road from either middle or side of the paver.

Engine:

Model TAD721VE

Type 6 cyliners, water-cooling

Power 195kW/2300r/min

Tank capacity 200 L

Driving system:the whole machine is controlled by hydraulic circuits, and the engine is connected with gearbox and three twin pumps, supplying power for many components as follows:

1.Traveling devices

2.Feeding devices

3.Vibration

4.Tamper bar

5.Body lifting and dropping

6.Cleaning system and all the executive cylinders

Traveling devices:consist of a pump, two valves, a speed control device, two motors and two reducers.

The two crawlers are driven by the two reducers.

Bearing mode:

two crawlers bear the weight of the whole machine, and the patch area of every crawler is 3000×320mm

Steering:

The rotate speed and steering of the two motors are controlled by two hydraulic valves, so the purpose of steering without shift can be achieved.

Electrical system:

24V DC supplied by two batteries is in charge of the whole circuit.

Control panel:

all sorts of handles are mounted on the control panel severely so as to be operated conveniently; the operator can observe the operating modes of all the components easily through fore-and-aft routeways .

Servomechanism:

a steering sensor and four grade sensors are equipped to adjust the body carriage and automatic steering automatically according to line transect.

Working devices:

1.Crown panbasic width……………………4250mm

2.Vibrators frequency……………………0~167Hz

3. Tamper bar rotate speed……………………0~170r/min

4. Screw rotate speed……………………0~34r/min

Main performance characteristics of the 1220MAXI-PAV SLIPFORM

1.The using of incorporate mechanism, electricity and hydraulic drive greatly improves the reliability of the whole machine.

2.A VOLVO 195kW water-cooling engine is used to supply driving and reliable powers.

3.The screw can be controlled from either side of the paver, so the effect of feeding is perfect.

4.The operator can observe the operating modes of all the components easily through fore-and-aft routeways.

5.All the control elements are mounted on the control panel severely so as to be operated conveniently.

6.The material of screws and crown pan is wearable and advanced in the world.

7.Because of the using of automatic leveling, the lengthwise flatness is not exceed 3mm(surveyed by 3m ruler),the transverse grade error:±2‰

8.Crawlers with life-time lubricated thrust wheels and track shoes wear well and are difficult to skid.

9.It can accomplish the cement concrete paving at one time.
