INTRODUCTION
Construction equipment have evolved as per changing requirements in the industry. Earlier for one job many equipment were required but now one equipment can do multiple jobs. Appropriate use of equipment contributes to completion of project on time, work speed, quality, and most importantly economy. It is not always possible for the contractor undergoing construction works to own each and every type of construction equipment required for the project due to complexity of project, shortage of skilled or efficient manpower, project involving handling of large quantity of earth materials, coping up with the time schedules, etc. However, one can purchase or hire the equipment as per suitability. If the equipment has to be used frequently and for a long duration of time then it proves to be economical to purchase the equipment. On the contrary, if the equipment has to be used occasionally and for a short duration of time, it proves to be economical to get it hired.

Abstract
The evolution of innovative printing techniques in the three-dimensional world goes on. Before we reported about the amazing rapid prototyping revolution, about printers that are able to print complete buildings and about the inkjet printer for streets. Now there is also the road printer. The Tiger Stone brick printer makes road construction as easy as laying laminate flooring. BLDGBLOG considers the invention of the Dutch company to be a real “road printer”.

Abstract: The construction industry’s contribution to the gross domestic product (GDP) in the developing countries like that of in India is about 10%. Under the Make in India scheme, it is expected that $1000 Billion investments for infrastructure sector would be accomplished in the next few years. Today the construction industry is one of the most unpracticed fields in terms of automation. The importance of construction automation has grown rapidly in developed countries. In developing countries like India, the construction industries need automation technologies such as new machineries, electronic devices , the automation of road, tunnel, and bridge construction; earthwork, etc.
The construction industry being labor intensive requires more numbers of skilled labor, good quality of work, and increase in productivity etc. The problems associated with construction work such as decreasing quality of work, labor shortages, and safety of labor and working condition of projects can be overcome by new innovative technologies such as automation which has the potential to improve the quality, safety, and productivity of the construction industry.
Today, it is evident that the level of automation in construction is very low in comparison with current technological advances. That is why we must make new efforts to increase the automation level of this important sector.

The old method to apply Gypsum manually took hours of labor and also had poor durability due to manual errors. Now with automation in this field, application through machine is gaining wide spread popularity as its not only faster but also cheaper in long run as very less labor is required.
More over the results are much more stronger and durable as compared to old methods. This is the machine which is used to apply Gypsum and we at engineeringcivil.com are thankful to Mr. Chandrahas Amin for submitting this picture to us.
Dump trucks or production trucks are those that are used for transporting loose material such as sand, dirt, and gravel for construction. The typical dump truck is equipped with a hydraulically operated open box bed hinged at the rear, with the front being able to be lifted up to allow the contents to fall out on the ground at the site of delivery.Dump trucks come in many different configurations with each one specified to accomplish a specific task in the construction chain.
Also known as a front end loader, bucket loader, scoop loader, or shovel, the front loader is a type of tractor that is normally wheeled and uses a wide square tilting bucket on the end of movable arms to lift and move material around.The loader assembly may be a removable attachment or permanently mounted on the vehicle. Often times, the bucket can be replaced with other devices or tools, such as forks or a hydraulically operated bucket.
Sometimes called a forklift truck, the forklift is a powerful industrial truck that is used to lift and transport material by steel forks that are inserted under the load. Forklifts are commonly used to move loads and equipment that is stored on pallets. The forklift was developed in 1920, and has since become a valuable piece of equipment in many manufacturing and warehousing operations.
Types of Forklifts
The most common type of design with forklifts is the counter balance. Other types of designs include the reach truck and side loader, both of which are used in environments where the space is at a minimum.
A crane is a tower or derrick that is equipped with cables and pulleys that are used to lift and lower material. They are commonly used in the construction industry and in the manufacturing of heavy equipment. Cranes for construction are normally temporary
structures, either fixed to the ground or mounted on a purpose built vehicle.
They can either be controlled from an operator in a cab that travels along with the crane, by a push button pendant control station, or by radio type controls. The crane operator is ultimately responsible for the safety of the crews and the crane.
The compact hydraulic excavator can be a tracked or wheeled vehicle with an approximate operating weight of 13,300 pounds.Normally, it includes a standard backfill blade and features an independent boom swing. The compact hydraulic excavator is also known as a mini excavator.
A compact hydraulic excavator is different from other types of heavy machinery in the sense that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid.The work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders.The rotation and travel functions are also activated by hydraulic fluid powering hydraulic motors.
The bulldozer is a very powerful crawler that is equipped with a blade. The term bulldozer is often used to mean any type of heavy machinery, although the term actually refers to a tractor that is fitted with a dozer blade. Often times, bulldozers are large and extremely powerful tracked vehicles. The tracks give them amazing ground mobility and hold through very rough terrain. Wide tracks on the other hand, help to distribute the weight of the dozer over large areas, therefore preventing it from sinking into sandy or muddy ground.
Bulldozers have great ground hold and a torque divider that’s designed to convert the power of the engine into dragging ability, which allows it to use its own weight to push heavy objects and even remove things from the ground. Take the Caterpillar D9 for example, it can easily tow tanks that weight more than 70 tons. Due to these attributes,bulldozers are used to clear obstacles, shrubbery and remains of structures and buildings.
