It is the fastest growing engineering machinery, machine production and sales and market demand one. We usually see the largest wheel loaders, it is acrawler loaders. Crawler than it has good mobility, does not destroy the road surface, easy to operate, etc.. Wheel loaders has been widely used. A loader (also known as: bucket loader, front loader, front end loader, payloader, scoop loader,shovel, skip loader, and/or wheel loader) is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground. A loader is commonly used to move a stockpiled material from ground level and deposit it into an awaiting dump truck or into an open trench excavation. Loaders in general by the chassis, powertrain, running gear, working device, steeringbrake, hydraulic system and operating system. The basis of the loader classification is the Society of Automotive Engineers of America (SAE) rated capacity of the bucket. The classification is based on the largest general purpose bucket offered by the manufacturer or the bucket size adopted by the Contractor, whichever is the lesser.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 scraper. The bucket can also be augmented with devices like a bale grappler for handling large bales
