In line with agricultural and industrial businesses, excavators are a prerequisite for faster and less complicated workloading. Throughout the high establishments found in busy cities and renowned commercial industry, behind them are the rough blocks and soil that were lined by bulldozers. Now let us appreciate how this useful machine is made and how it undergoes complete machining, fabrication and sub-assembly with the help of a computer aided drafting program that assembles and integrates the different metals and parts to form the final product of an excavator.
First of all, the process of making an excavator goes through 10 steps that will be discussed in a simple way so that the public understands how this machine turns from raw materials into a noisy, gigantic and destructive or constructive engine. The complex system and intricate assemblies begin their manufacturing process on an assembly line. A schematic is prepared from printouts and engineering drawings taken from a computer-aided drafting (CAD) that will serve as a blueprint for the assembly of the parts. Components will be heat treated, annealed or painted beforehand in preparation for shipment to the main assembly line.
1. The main core, which forms the rigid inner body, is responsible for the following assembly. Cut and shape the steel plate to complement the structural shape. The main purpose behind this is to prevent high impact shock loads and twisting forces that will topple the bulldozer due to its enormous weight. In this process, the components undergo steel welding (regarding the structural skeleton); fabrication in which plates are mounted on fixtures and manually or robotically welded to the stationary central foundry; and the cross members are also welded to support the other component of the excavator. The frame is then rotary sanded on all veneered surfaces which, in turn, will be passed on to the cockpit and main assembly line.
2. On the assembly line, the diesel engine at the front and the transmission at the rear (the two are connected by a long shaft and supported by couplings and bearings) are assembled, so the power train is formed due to the long connected line of the two, with series of gears and differentials. This bolts directly to the base on the main assembly line.
3. Radiator and hydraulic lifting cylinders are located at the front of the excavator, apart from that, connections are made to join the engine water lines. Other additional assemblies such as hydraulic, lubrication, cooling and fuel systems are also built and therefore the assembly will be ready to be attached directly to the engine.
4. The cab, which in conjunction with electronic controls, is mounted on steel blocks or pads located on the dozer frame.
5. The undercarriage is mounted on the frame and assembled to the drive train.
6. Cab controls are linked to the engine and hydraulic systems.
7. The front blade is attached to hydraulic cylinders, which are attached at one end to the engine casting in front of the excavator.
8. Once the main component assembly is fitted, more hoses, electrical lines and fluid lines are connected to the tight fittings.
9. The excavator is then painted after the assembly of the necessary parts is completed.
10. Additional fluids will need to be put in and the excavator is now set up for the test station.
