Side tipper

from Wikipedia, the free encyclopedia
Side tipping loader EL 600

A side dump truck is a loading machine that is used to lift and move debris . In the mining industry , side tipping trailers are mainly used underground to drive the road . But side tipper loaders are also used in mining operations and in tunnel construction .

construction

The base of the loader is the undercarriage. The chassis is mounted on the undercarriage. This usually consists of two crawler tracks. There are also versions that have rubber tires. A bucket boom is attached to the front. The loader bucket is mounted at the front of the bucket arm. This loader bucket is open on one side. The discharge side can optionally be set to the right or left. In order to be able to move the chassis and the shovel, the loader is equipped with a hydraulic system. This system consists of the hydraulic pump and several lifting and tilting cylinders. A drive motor is available to drive the hydraulic pump. For the hydraulic fluida hydraulic tank is mounted on the loader. In addition, there are separate control devices that are used to operate the loader shovel and the landing gear. Each of the trolleys can be controlled individually. This makes it possible to turn the loader on the spot. In addition, a driver's seat for the loader driver is mounted on the loader. By adding a bottom sinker shovel , the loaders can also be used for lowering work . It is also possible to add a special shovel in order to load on higher conveyors. Such modified loaders are called high-tipping loaders. In addition, it is possible to attach additional tools such as a ripper hammer to some modified loaders.

Energy supply and function

The charger is supplied with energy either with compressed air or electrohydraulically, depending on the version. But there are also loaders powered by diesel engines. In the case of compressed air-operated loaders, the chassis is driven by an air motor , the shovel is moved hydraulically. The loader arm is either rigid or telescopic and is moved hydraulically. The telescopic arm can be moved in all directions. Depending on the type of loader, the loader arm can be moved 15 degrees to the right and left, with some types 20 degrees. The crawler tracks are driven individually and independently of each other.

Dimensions and properties

Side tipper loaders are up to two meters wide and, when the loader arm is extended, can be up to four meters long. The height of the loader is up to 1460 millimeters. These dimensions are specially selected for use in underground areas. Due to the low overall height, it is possible to drive the loader under drilling and working platforms. The drive power of the loader is twelve kilowatts for smaller loaders , while large loaders have an output of up to 75 kilowatts. The loader bucket capacity is between 0.45 and 1.2 cubic meters. The loader is very maneuverable and can travel at speeds of up to 1.4 meters per second. The side tipper has good climbing ability. Depending on the loader's capacity, inclines of up to 25 gon can be mastered. This means that they can also be used on ascending routes. However, especially in the case of inclined and steep storage, the bottom must be relatively flat so that the loader shovel does not climb when picking up the debris.

Working method

To pick up the pile, the loader is driven into the pile with the lowered shovel. In order to be able to achieve a good loading capacity, the debris must be shredded and ready for loading. After the bucket is filled, the bucket is raised and the loader is then moved back to the conveyor. To empty the shovel, it is tilted to the side over the conveyor. In order to enable the tipping process, the funding for this must be correspondingly low. The loader must be converted into a high-tipping loader so that the pile can also be tipped onto trolleys .
