The loader assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools--for example, many can mount forks to lift heavy pallets or shipping containers, and a hydraulically-opening "clamshell" bucket allows a loader to act as a light dozer or loader

Loaders
主讲：晏华和 学号：20100822
Basic Concept
A loader is a type of construction equipment (engineering vehicle) machinery that is primarily used to "load" material into another type of machinery (dump truck, conveyor belt, rail-car, etc.).Loaders are used mainly for uploading materials intotrucks, laying pipe, clearing rubble, and digging.

Applications
•1. loading materials
•2. earthmoving
3. Forestry engineering
•4. snow removing
•5. underground work
•6.loading and unloading
In construction areas loaders are also used to transport building materials - such as bricks, pipe, metal bars, and digging tools - over short distances. Loaders are also used forsnow removal, using their bucket or a snow basket, but usually using a snowplowattachment. They clear snow from streets, highways and parking lots. They sometimes load snow into dump trucks for transport.

A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe can. Their deep bucketcan usually store about 3-6 cubic meters of earth. The front loader's bucket capacity is much bigger than a bucket capacity of a backhoe loader. Loaders are not classified as earthmoving machinery, as their primary purpose is other than earthmoving.
