5. Output of Ripper
• Excavating land in a less time and provides good product.
• It increases the efficiency of work.
• The product obtained from ripper is used for various purpose.
• It excavate soil which is in front of blade keeps on rolling, thereby
reducing frictional drag.
• It is quietly used for back filling.

6. Uses of Ripper:
The rippers are used to carry out:
• Excavation for foundations.
• Removing deposits of clay and gravel.
• It is used for excavation of drain pipes.
• It is useful in cutting roads in hills.
• It is useful for cutting ditches.

7. Factors affecting selection of Ripper:
• Size required for a given job.
• Kind of job for which it will be used.
• Firmness of haul road.
• Slope of haul road.
• Length of haul road.
• Type of footing over which it travel or its require high or low tractive
efficiency.

LIFE OF
RIPPER

9. Maintenance and repair cost:
• The repair and maintenance cost includes the cost of replacement parts, labor
charges and the cost of setting up and operating facilities to carry out major
repair and maintenance operations.
• The repair and maintenance cost varies from one year to another over the
service life of the equipment, however it increases with age of the equipment.
• The annual repair and maintenance cost can be calculated as a percentage of
the annual depreciation cost of the equipment.

10. Use on site along with market survey for
availability, cost
• used to push large quantities of soil, sand, rubble, or other such material
during construction or conversion work and typically equipped at the rear
with a claw-like device (known as a ripper) to loosen densely compacted
materials.
• Rippers can be found on a wide range of sites, mines and quarries, military
bases, heavy industry factories, engineering projects and farms.
Cost varies as it depends on types of Rippers like:
• Vibro ripper : 3300000
• Hydraulic ripper: not same like cost like vibro ripper.
