A wheel loader is a big piece of heavy machinery with a bucket or basket on the front. Its job is to move materials or trash from one place to another.
If you pay attention to how the wheel loader works, you will notice that a hydraulic system drives the engine. This is because hydraulic power can make a lot of power so that the wheel loader can carry a lot of weight at once.
Every part of the wheel loader needs to be connected to work right. This big equipment is made up of different parts that all work together.
Here’s what you need to know about the wheel loader’s parts and how they work.
1. Bucket
The most important part of a wheel loader is the bucket or basket. This part is very important in helping people dig, load materials (like stone, sand, or wood), and move goods.
Each wheel loader is a different size and shape, so it can be changed to fit the job. For example, bucket grapples work well in forests because they can move a lot of tree trunks and branches at once.
2. Boom
The boom connects the wheel loader’s bucket and the wheel loader’s body. The boom must be made of a strong material that can hold heavy loads and resist being pushed so it can be used repeatedly.
The length and size of the boom determine how far and how high the bucket can reach to pick up or drop off materials. If a boom is too short, it can be harder to load goods or stack materials in high places.
3. Boom Cylinder
The wheel loader has two hydraulic cylinders on each side of the boom that make up the boom cylinder. The boom cylinder controls how high and low the boom goes when it is being used to move materials.
This part needs to be strong enough to lift a lot of weight.
But operators still have to be careful when using a wheel loader, especially with the boom cylinder, so that it doesn’t get broken when the boom is lifted or moves sideways.
4. Linkage
This part is important because it has a pin that connects the parts that turn to each other.
Even though this part looks simple, its length, number of links, and shape all affect how the bucket moves and tilts when the cylinder is turned on.
The linkage on a wheel loader looks like the letter “Z.” When the machine is being used, the operator must control both the bucket cylinder and the boom cylinder at the right time so that there are no mistakes when the bucket is being raised or lowered.
5. Bucket Cylinder
A hydraulic cylinder in the middle of the wheel loader boom connects the wheel loader to the bell crank.
Because of how the bellcrank and linkage are set up, the bucket cylinder can be extended. This lets the operator tilt the bucket forward to dredge material into the bucket.
The bucket cylinder also allows the operator to tilt the bucket away from the cab to move material.
6. Bellcrank
The bell crank connects the bucket, the bucket cylinder, and the boom. So it makes sense that the bellcrank job is so hard.
This part is a simple lever that turns in the middle, which lets the operator tilt the bucket.
7. Rim dan Tires
A wheel loader is easy to move on hard, level, and solid ground. This is because the wheel loader can move. After all, it has rims and tires that help it move.
A wheel loader’s rim must be able to withstand heavy loads. So it makes sense that the wheel loader’s rim is pretty big.
Also, their tires must be made to run on the ground and aren’t easily broken when they step on a rough or bumpy surface.
8. Axle
Agar dapat berbelok dengan mudah, sebuah wheel loader dilengkapi oleh axle atau gardan pada bagian depan dan belakang dengan ukuran yang besar. Bagian ini menghubungkan sistem penggerak wheel loader ke bagian roda.
Pada suatu waktu, wheel loader dapat mengalami benturan yang keras dari arah bawah. Untuk itu, poros gardan serta roda gigi internal yang berada di dalam gardan membutuhkan rumah gardan yang sangat kuah dan kokoh agar tidak mudah mengalami kerusakan.
9. Differentials
Both the front and back of the wheel loader have differentials.
It is in the middle of the axle, which changes the direction of power and has a gear system that lets the wheels on the same axle turn at different speeds in certain situations, like when turning corners.
10. Final Drives dan Brake Groups
A unit called the final drive and brake group (brake group) is in the wheel loader axle. The final drive comprises several gear systems and is the last place where power is turned into high torque before it goes to the wheels.
11. Transmission
The wheel loader’s transmission is based on gear ratios, which allow it to work at different speeds and with different amounts of torque when power is sent from the engine to the transmission and then to the wheels.
Some wheel loaders use a torque converter for the transmission, but a hydrostatic transmission can also be used.
12. Engine (Mesin)
The engine is the most important part of a wheel loader because it turns fuel into power that can run the drive, hydraulic, and other systems in the wheel loader.
The engine on a wheel loader is made to put out a lot of power and still work well, even in harsh environments or when doing hard work.
13. Main Control Valve
The flow direction and pressure in the hydraulic system of each part of the wheel loader are controlled by the main control valve or main control valve.
14. Cab (Kabin)
The cabin that belongs to the wheel loader is where the operator sits while the wheel loader is being used. The operator inside the cab is protected by strong safety equipment.
The cab is set up so that the driver has a clear view of everything and is not blocked by anything. Over time, changes were made to the wheel loader’s cabin.
The cabin has been made more comfortable and is also a good place for the operator to keep an eye on what’s happening around the work area.
These are some of the parts of a wheel loader that you need to know about. Each part of the wheel loader has a very important job, so it needs to be maintained regularly so that material transportation can go smoothly.
