CONCRETE PAVER MACHINE - ROAD PROJECTS

High precision cylinder finisher pavement for concrete slabs such as Streets, Parking, Factory floors, Bridges, Airports, Tennis Courts etc.
It can finish a width from 3.5 mts. to 20 mts
Machine can finish upto 150 Sq. meter / hour at suitable site condition.
Light weight construction for easy erection and transportation from site to site
The special Under carriage consists of a spreader augar to spread the concrete to level, The finishing Cylinder to compact and finish the concrete to the grade
Finishing roll bracket can be equipped with vibrator (Optional)
Works to any slab height
Special texturing and curing machine are made to get line on concrete surface and spraying curing compound (Optional)
When the road paving works special arrangement is made to create camber on road.
UNISTEEL RCP 750 PAVER MACHINE is also equip with two Needle vibrators and it inserts automatically in fresh concrete one after other, this will give vibrating deep in slab height creating a homogeneous bounding of slab without air gap in between the concrete slab. This function is not in any other method. One should insert manually needle vibrator in any other method of paving except slip-form method. In manual method it is not possible for man to get each and every portion of concrete cannot be achieve. (Optional)
Toeing arrangement of UNISTEEL RCP 750 PAVER MACHINE is very easy to attach, simply fix bolts and it is ready for toeing. There is no need to take any part of paver away for fixing the toeing arrangement. In less time you can sift the paver from one end to another. (Optional)

The frame structure is light in weight and therefore very easy for transport and erection.
The frames are available in the lengths of 4feet; 8feet and 12feet.These is pin bolted together according to the size of the slab width.
RCP-750 can be incorporated in use for a working width between 3mtr to 20mtrs.
Hydraulically operated needle vibrators are provided on the mobile assembly to stir the concrete to remove any air bubbles if present in the mix and thus reduce the porosity. Due to Needle Vibrator may struck side partition you have to do 400mm manually on both side (Optional)
Hydraulic Needle vibrators vibrate with a frequency 10,500 vpm. (Optional)
The paving is carried out with a Vibrating-finishing drum of 4 feet in length and 10.7 inches (272 mm) in diameter.
The finishing drum is equipped with vibrator to achieve better finishing.
Crowning arrangement is provided for cambering the surface of the road.
4 no's of mechanically adjustable jacks are provided for maintaining the machine level.
The forward and reverse motion of the machine is controlled by hydraulically operated bogie.
The finishing drum bracket has an ability to swivel at an angle of 20° in either direction to accommodate harsh mix for a quality finish.
Leveling screws are used to level the rails on which the machine moves to maintain the smoothness of surface and to avoid irregular paving.

PRIME MOVER (with Needle Vibrator)	10HP 1440-RPM for fix Console. 20HP 1440-RPM for under carriage.
PRIME MOVER (without Needle Vibrator)	10HP 1440-RPM for fix Console. 10HP 1440-RPM for under carriage.
Fix Console	This Hydraulic console controls the forward and reverse movement of the under carriage and the travel bogie by means of hydraulic motors.
Under Carriage/Finisher Assembly	Under Carriage accommodates the most critical components of the machine. It encompasses the vibratory finishing drum, Needle vibrators, Spreader Auger. The Under Carriage travels with a speed 30 mtrs/min.
Vibratory Finishing Drum	The finishing drum is 4 feet in length and 10.7 inches (272 mm) in diameter. It rotates at a speed of 195 rpm. The finishing drum vibrates at 1500vpm.This Drum is precisely balance with the help of computerized balancing system to obtain quality finish.
Spreader Auger	The Auger is welded with hard faced welding to obtain maximum life. The auger is designed to work in the direction of travel movement of the machine.
Angular Needle Vibrators (Optional)	Minnch-USA makes angular needle vibrators with 10,500 vpm. These dual vibrators are designed with an angular twist in the opposite directions. These vibrators operate alternately by penetrating in to the concrete depth with the direction of twist along the motion of the under carriage.
Hydraulic Oil Capacities	Fix console: 110 liters Under carriage: 140 liters.
Traction System	Traction Drive : Two hydraulically driven flanged wheels bogie. Traction Speed: Up to 52 feet/min (15.86 mtrs/min).

Frame : All-welded steel, pin-connected mainframe. The frames are available in the lengths of 4feet; 8feet and 12feet.These are bolted together according to the size of the slab width. For working widths beyond 10mtrs over truss assembly is used.

Variable Finishing Widths : The finishing widths of 3.5 mtr to 20 mtrs can be obtained by bolting the frames, which are available in the lengths of 4 feet, 8 feet and 12 feet.

Preparation steps :

Step 1 : Leveling and compaction of the sub-grade.
Step 2 : Erection of the machine.
Step 3 : Level of the 50lbs rails with the help of rail setting bolts.
Step 4 : After completing the erection the pitch rail on which the undercarriage slides is thoroughly leveled with the help leveling screws provided within the frame.
Step 5 : According to the slab height, the finishing drum is leveled with the help of four mechanical jacks.
Step 6 : The side panels are erected according to the dimensions specified for the concrete slab.
Step 7 : The machine is now ready for paving.

After pouring the concrete on sub-grade the machine will move in the forward direction and the Undercarriage moves to and fro in a transverse direction.
The Undercarriage completes one cycle when it travels the entire width of the slab to and fro.
Hydraulically operated needle vibrators are provided on the mobile assembly to stir the concrete to remove any air bubbles and reduce the porosity. Due to Needle Vibrator may struck side partition you have to do 400mm manually on both side
Spreader augers are used to spread the excess material, which comes in the way of finishing drum.
The first pass of the cycle is the compaction pass while the second pass is called the finishing pass.
After Undercarriage completes one cycle the machine moves in the forward direction.
