GENERAL SPECIFICATIONS

• The frame structure is light in weight and therefore very easy for transport and erection.

• The frames are available in the lengths of 4 feet; 8 feet and 12 feet. These are pin bolted together according to the size of the slab width.

• RCP-750 can be incorporated in use for a working width between 1mtr to 25mtrs.

• For working widths beyond 10mtrs over truss assembly is used.

• 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.

• Hydraulic vibrators vibrate with a frequency ranging between 8,000 to 10,000 vpm.

• The paving is carried out with a finishing drum of 4 feet in length and 10.7 inches (272mm) 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 50 lbs rails on which the machine moves to maintain the smoothness of surface and to avoid irregular paving.

 

TECHNICAL DETAILS

UNISTEEL-RCP750 CYLINDER FINISHER
PRIME MOVER:
10HP 1440-RPM Crompton motor for fix Console.
20HP 1440-RPM Crompton motor for under carriage.(When fitted with Hydraulic Needle Vibrator)
10HP 1440-RPM Crompton motor 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 30mtrs/min.

Vibratory Finishing Drum:
The finishing drum is 4 feet in length and 10.7 inches (272mm) in diameter. It rotates at a speed 295 rpm. The finishing drum vibrates at 2500vpm. This Drum is precisely balance with the help of computerized balancing system to obtain quality finish. Life of the finishing drum is approximately 30,000 sq.mts.

Spread Auger:
The Auger is welded with hard faced welding to obtain maximum life. After every 4000Sq.mts. of working the auger is required to be hard faced. The life of the Auger is approximately 35,000 sq.mts. The auger is designed to work in the direction of travel movement of the machine. The diameter of the auger is 267 mm and a pitch of 100mm throughout the length of 500mm.

Angular Needle Vibrators [Optional] :
Minnch-USA make 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).

CONSTRUCTION:

Frame
All-welded steel. Pi-connected mainframe. The frames are available in the lengths of 4 feet: 8 feet and 12 feet. 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 1 mtr to 25 mtrs can be obtained by bolting the frames, which are available in the lengths of 4 feet, 8 feet and 12 feet.

TRIMMER ASSEMBLY [Optional]
Trimmer assembly for fine grading the sub grade. Carbide tip cutters for trimming the surface to get fine surface finish of the sub-grade. This assembly can be fitted by detaching the finishing drum.

PREPARATIONAL 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.
