Plot 219, Sector-58, Ballabgarh, Haryana DEPARTMENT OF INDUSTRIAL ENGINEERING & MANAGEMENT R. V. COLLEGE OF ENGINEERING, BANGALORE560059 (Autonomous Institution Under VTU, Belgaum) CertificateCertified that the Mini Project work entitled “Welding and Fabrication” is a bonafide work carried out by Rishabh Shah-1RV08IM053 in partial fulfilment of the academic requirements of VII semester in the engineering course in Industrial Engineering and Management during the year 2010-11. Date: Signature: ACKNOWLEDGEMENT We would like to thank our project mentor Mr.
Vinod Chauhan, ECEL who has been a guiding light for the project. Also, Mr. Amit Yadav, HR-ECEL for giving me this opportunity to carry out the project.
A sincere vote of thanks to the staff of ECEL, without whose cooperation, I would not have competed the project.Project Synopsis The objectives of this project were to understand the functioning of backhoe loaders and its components and then analyzing the assembly line for bottleneck operations and suggesting ways to eliminate them. The current strength of workers is 89 spread over eight broadly categorized assembly stages. The production on an average working day is 3-4 BHLs which needs to be improved. Most of the work done is manual, using power driven tools. Therefore, improving worker efficiency and synchronization of work were key elements to be looked into for improving production.

Having pioneered farm mechanization in the country, Escorts has played a pivotal role in the agricultural growth of India for over five decades. One of the leading tractor manufacturers of the country, Escorts offers a comprehensive range of tractors, more than 45 variants starting from 25 to 80 HP.Escort, Farmtrac and Powertrac are the widely accepted and preferred brands of tractors from the house of Escorts. A leading material handling and construction equipment manufacturer, we manufacture and market a diverse range of equipment like cranes, vibratory rollers and forklifts. Escorts today is the world’s largest Pick ‘n’ Carry Cranes manufacturer. Escorts has been a major player in the railway equipment business in India for nearly five decades. Our product offering includes brakes, shock absorbers, rail fastening systems, composite brake blocks and vulcanized rubber parts.In the auto components segment, Escorts is a leading manufacturer of auto suspension products including shock absorbers and telescopic front forks. Over the years, with continuous development and improvement in manufacturing technology and design, new reliable products have been introduced. Throughout the evolution of Escorts, technology has always been its greatest ally for growth. In the over six decades of our inception, Escorts has been much more than just being one of India’s largest engineering companies.It has been a harbinger of new technology, a prime mover on the industrial front, at every stage introducing products and technologies that helped take the country forward in key growth areas. Over a million tractors and over 16,000 construction and material handling equipment that have rolled out from the facilities of Escorts, complemented by a highly satisfied customer base, are testimony to the manufacturing excellence of Escorts. Following the globally accepted best manufacturing practices with relentless focus on research and development, Escorts is today in the league of premier corporate entities in India.Technological and business collaboration with world leaders over the years, globally competitive indigenous engineering capabilities, over 1600 sales and service outlets and footprints in over 40 countries have been instrumental in making Escorts the Indian multinational. At a time when the world is looking at India as an outsourcing destination, Escorts is rightly placed to be the dependable outsourcing partner of world’s leading engineering corporations looking at outsourcing manufacture of engines, ransmissions, gears, hydraulics, implements and attachments to tractors, and shock absorbers for heavy trailers.

For this we are going beyond just adhering to prevailing norms, we are setting our own standards and relentlessly pursuing them to achieve our desired benchmarks of excellence. Overview of Backhoe Loaders (BHLs) Backhoe loaders have a very unique appearance- they have components sticking out every which way.A backhoe loader is an interesting invention because it is actually three pieces of construction equipment combined into one unit. A backhoe loader is: * A tractor * A loader * A backhoe Each piece of equipment is suited to a particular sort of work. On a typical construction site, the backhoe operator usually uses all three components to get the job done. The Tractor The core structure of a backhoe loader is the tractor. Just like the tractors that farmers use in their fields, the backhoe tractor is designed to move easily over all kinds of rough terrain.It has a powerful, turbocharged diesel engine, large, rugged tires and a cab with basic steering controls (a steering wheel, brakes, etc. ). Backhoe cabs are either completely enclosed or have an open canopy structure to give the operator protection. The Loader The loader is attached in the front and the backhoe is attached in the back. These two components serve very different functions. The loader can do several different things. It is mostly used it to pick up and carry large amounts of loose material. It is also used to smooth things over, or to push dirt.The operator controls the loader while driving the tractor. The Backhoe The backhoe is the main tool of the backhoe loader. It’s used to dig up hard, compact material, usually earth, or to lift heavy loads, such as a sewer box. It can lift this material and drop it in a pile to the side of the hole. Basically, the backhoe is a big, extremely powerful version of your arm or finger. It has three segments: * The boom * The dipper * The bucket The backhoe segments are connected by three joints, comparable to your wrist, elbow and shoulder.The backhoe moves in pretty much the same way as your arm. In a backhoe, the boom is bent upward to make it easier to dig with obstacles in the way. This design also provides extra space for the bucket when the operator curls it in with a full load. The backhoe can dig all sorts of holes, but is especially suited for digging ditches. To use the backhoe, the operator has to park the tractor and turn the seat around. The most common application for a backhoe loader is this basic job – digging a trench with the backhoe and then back-filling it with the loader. Existing ProblemThe assembly line comprises of eight stages with different tasks at each station along the assembly line. However there was a lack of coordination in activities seen. For example, the task to be completed in the 2nd stage is done when the chassis is moved onto the next station, resulting in increased material handling and a haphazardness of operations. This is because some operations take longer than others and are hence critical to plant productivity. Also, a low morale and lack of motivation was seen in the workers, which in a labor intensive setup can affect production adversely. Objectives
