Loaders

1. Loaders are used mainly for uploading materials into trucks, laying pipe, clearing rubble, and digging. 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. The capacity of a loader bucket can be anywhere from 0.5 to 36 m 3 depending upon the size of the machine and its application. The front loader’s bucket capacity is generally much bigger than a bucket capacity of a backhoe loader.

 2. Unlike most bulldozers, most loaders are wheeled and not tracked, although track loaders are common. They are successful where sharp edged materials in construction debris would damage rubber wheels, or where the ground is soft and muddy. Wheels provide better mobility and speed and do not damage paved roads as much as tracks but provide less traction.

3. Front loaders are commonly used to remove snow especially from sidewalks, parking lots, and other areas too small for using snowplows and other heavy equipment. They are sometimes used as snowplows with a snowplow attachment but commonly have a bucket or snow basket, which can also be used to load snow into the rear compartment of a snowplow or dump truck. High-tip buckets are suitable for light materials such as chip, peat and light gravel and when the bucket is emptied from a height.

4. Unlike backhoes or standard tractors fitted with a front bucket, many large loaders do not use automotive steering mechanisms. Instead, they steer by a hydraulically actuated pivot point set exactly between the front and rear axles. This is referred to as “articulated steering” and allows the front axle to be solid, allowing it to carry greater weight. Articulated steering provides better maneuverability for a given wheelbase. Since the front wheels and attachment rotate on the same axis, the operator is able to “steer” his load in an arc after positioning the machine, which can be useful. The tradeoff is that when the machine is “twisted” to one side and a heavy load is lifted high, it has a greater risk of turning over to the “wide” side.
