The real challenge before us as a country is the availability of low sulphur fuel that determines the emission of a particular engine, says DV Brahme, Regional Manager, Mait India. Excerpts from the interview.
How do you look at the concept of green technology with regard to achieving cost efficiency in a holistic way?
On the face of it, green technology with regard to achieving cost efficiency looks contradictory from a commercial point of view in the present situation. However, every individual or living thing like plants and animals existing in the world is affected by the deterioration of environment in one way or the other. Generally it is taken for granted that if one is looking for green technology, one should be ready to spend extra for the exclusive but expensive technology.
The holistic way of looking at it is to distribute the extra amount spent over the above-mentioned living beings in the world. Form this point of view it is negligible. If one considers the well-being of future generations, it is the absolute duty of everyone of us to adopt green technology.
The green technology is not limited only to reducing the emission from engines but it also is to avoiding the wastage of anything and everything that needs consumption of energy to create or produce.
How is Mait India geared up to meet the challenges?
MAIT always has been at the forefront in adopting green technology, including switching to engines having lower emission. All MAIT equipment have always been fitted with the engines complying with the latest emission norms.
However, the real challenge before us as a country is the availability of low sulphur fuel that determines the emission of a particular engine. Even with the current emission norms sometimes it becomes difficult at remote job site to get acceptable quality of fuel. The adulteration of fuel with other low cost chemicals is still taking places in many places. To stop it is real challenge.
Brief us on the inbuilt features that bring fuel/energy efficiency into your products?
MAIT rigs are fitted with the engines complying with the latest emission norms in the world. The drive system has the highest efficiency to minimise the losses. The hydraulic system is specially designed for foundation work that achieves faster speed and high torque resulting in higher productivity.
Piling, a method of foundation, for which these rigs are used, is fuel efficient and eco-friendly, as it avoids movement of large quantity of material from one place to another (excavation-carting-dumping and back filling), that saves fuel, time as well as space. Drilling by rotary system also minimises the over-boring while drilling that avoids the excess consumption of concrete (wastage) thereby reducing the heat emitted during the making of that concrete.
Do you have any features inbuilt to reduce vibration and noise?
Rotary drilling process as such is a vibrationless method of drilling and the spin off system of unloading the muck from the auger is a noiseless system unlike some other rigs that do not have a spin off system and the operator in order to unload the muck needs to give jerks to the Kelly bar and tool that creates deafening noise.
What are the measures taken to make the machines safer?
There are many built-in safety features in MAIT rigs. Some of the features are mentioned below:
a) Cabin cut off - the moment operator gets up from his seat, all the hydraulic functions stop automatically to avoid accident.
b) The operator cabin has fallover protection system (FOPS).
c) There are emergency shut off buttons provided inside the operator cabin as well as on the outside body of the rig that is accessible to other persons at site.
d) The hydraulic circuit has a system that automatically stops supply of hydraulic oil to a particular function, in case of damage to the tubes or hoses, avoiding further accident and loss of hydraulic oil.
Brief us on the steps initiated to train the operators and technicians.
Mait has specially developed training modules not only for operators but also for mechanics and engineers. Often practical as well as classroom training sessions are conducted by MAIT at the job site.
MAIT has a full-fledged training center in its office in Mumbai where we also conduct internal training for refreshment of knowledge of staff members.
