Construction activity of any kind starts with digging the earth and making the way for construction of foundation. The various equipments are used for earth work. Use of each of these equipments depends on the nature of work to be done.
Backhoe tractors are on the wheels or tracks and have backhoe at the end of the arm, which can be extended from the tube for work. The backhoe works on the hydraulic pressure. The digging is done from the short distance of the machine towards the machine. The depth of the digging depends on the length of the arm and depth to which its blades can go.
Loading shovel is similar to backhoe tractor but the only different is that the arm of the loading shovel extends upward and lifts the material for loading into bumper trucks. The loading shovels operate on tracked chain and can be taken to any surface during loading. The track chain gives it stability during lifting and loadings. The machine comes in various sizes and capacities.
Graders are used to spread the mud over the surface evenly and finely trim the subgades. They consists a blade which is wide and can be lifted or moved forward through hydraulic cranes at the two ends of the blade. The front wheels of the graders are articulated, while the rear wheels are ser under the control unit and motor unit.
Dumper trucks Construction equipment suppliers in India are widely used for their carrying loose material for construction site. They have back carriage, which can be uplifted by the hydraulic cranes to dump the material loaded on the trucks. These trucks vary in capacity from one ton to 80 ton. The choice of the particular dumper truck depends on the material quantity to be carried. Some dumper trucks have back carriages that can be tilted toward the sides to unload the loose material. The speed of the unloading is very fast in dumper trucks as they do not have any gate at the end of the back bumper. The slightly lifted portion of the back end keeps loose material inside the truck.
Bulldozer is a tracker with front blades that are raised and lowered as per the requirement of the job .The bulldozers use tracks and can be very stable for the job. They are used for heavy lifts. The tracks allow bulldozers to move on variety of ground surface easily. Some bulldozers come with blades, which push away materials to sides as bulldozer moves.
Before the start of the construction, Laboratory equipment suppliers in Delhi civil or geothermal engineers test for soil for its suitability for construction. The soil testing can be done on the spot with right equipments or in a laboratory.
