Loader tool can be classified as a mover loader crawler wheels or tires. Wheel loaders crawler or crawler-tractor-mounted has a wheel similar to dozer only installed more forward to stabilize the tool when transporting material. Wheel loaders tire or wheel-tractor-mounted consists of four-wheel-drive and rear-wheel drive. Rear-wheel-drive can be used to dig and 4-wheel-drive is suitable for carrying fully loaded bucket.
Both wheeled loader tires on wheels or crawlers can be used to lift the material. But the bottom of the material should have a height as high as the surface where the device is located. Appointment of a deeper need a ramp. Besides the material loose material must be removed. Because there is no bottom loader rotator then at dismantling its cargo loader had to do a lot of movement.
Loader given additional attachments such as buckets, forklifts and backhoes that additional tools on the construction project can be reduced. Which is attached to the loader bucket can be either general purpose buckets and multipurpose bucket. In the multipurpose bucket, bucket consists of two parts that can be opened in the middle like a clamshell. Bucket sizes ranging from 0.15 m3 to 15 m3 .Ukuran most commonly used is 6 m3.

Operation TechniquesIn the operation of the loader, there are some things that must be considered. Matters relating to the charging bucket loader and loader unloading important to note that the tool works more efficiently under certain conditions.
Loading Bucket LoaderCharging by the loader bucket is first done by the end of the bucket touches the ground. Then the loader forward slowly until the material entered and the bucket down. When the material entered the lift bucket so that the material is not ketuar.
Cargo demolition Bucket LoaderAs has been explained earlier that the loader is used to load material into a truck. Techniques loading material from the bucket into the tailgate needs to pay attention to the following points:
- As he moves forward, arm and bucket lifted.
- When the bucket is above a truck, the bucket is rotated slowly downward.
- After the empty bucket swivel upwards and backwards slowly.
- Demolition should be carried out on the driver's side of the truck.
On a flat area near the truck can be placed in the loader so that the movement of the loader will be easier. There are three methods of loading material from the loader into the truck, namely:
- I shape loading.
- shape loading.
- Pass loading.
Loader lifting capacity is influenced by several factors. These factors include:
- Heavy machinery Heavy machinery needs to be known so that the material does not exceed the weight of heavy tools that can lead to tipping.
- Location gravity tool that is not high emphasis avoidance of somersault.
- Long radius between the center of rotation of tools and lifting power tool attachment will be smaller with the growing length of the radius.
- The greater power tools power tool appliance greater lift capability.
Productivity LoaderFactors to be considered in determining the productivity of the loader are as follows:
- Material conditions.
- Bucket-type and capacity.
- Area for the movement of the loader.
- Loader cycle times.
- Time efficient loader.
