The ten steps of the manufacturing process of a bulldozer

In line with agricultural and industrial businesses, excavators are a prerequisite for faster and less complicated work loading. Along with the tall establishments found in the busy cities and the renowned commercial industry, behind them are the raw blocks and soil that were resurfaced by excavators. Now let’s appreciate how this useful machine is made and how it undergoes complete machining, fabrication and sub-assembly with the help of a computer aided drawing program that assembles and integrates the different metals and parts to form the final product of an excavator.

First of all, the manufacturing process of an excavator goes through 10 steps that will be discussed in a simple way so that the public understands how this machine is converted from raw materials into a noisy, gigantic and destructive or constructive engine. Complex system and intricate assemblies begin their manufacturing process on an assembly line. A schematic is prepared from prints and engineering drawings taken from a computer-aided drawing (CAD) that will serve as a blueprint for assembling the parts. Components will undergo heat treatment, annealing, or painting 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 avoid high impact shock loads and twisting forces that will topple the dozer due to its enormous weight. In this process, the components go through steel welding (in terms of the structural skeleton); fabrication in which plates are mounted on fixtures and manually or robotically welded to the stationary central casting; and the cross members are also welded to support the other excavator component. The frame is then rotary sanded on all veneered surfaces which will, in turn, go through to the cab and main assembly line.

2. On the assembly line, the diesel engine at the front and the transmission at the rear are assembled (the two are connected by a long shaft and supported by couplings and bearings), 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. At the front of the excavator are the radiator and hydraulic lift cylinders, 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 directly attached to the engine.

4. The cab, which in conjunction with electronic controls, is mounted on steel blocks or pads located on the frame of the dozer.

5. The undercarriage is mounted on the frame and assembled to the drive train.

6. The cab controls are connected 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 complete, more hoses, power lines, and fluid lines are attached to the tight fittings.

9. The excavator is then painted after completing the assembly of the necessary parts.

10. Additional fluids will need to be put in and the excavator is now set up for the test station.
