Backhoe loader classification and application scope introduction
In 1947, the Wain-Roy Corporation developed and tested the first true excavator. Light and Power Company for $705.
Applicable scenarios for backhoe loaders:
Construction projects of any complexity.
Various road works.
Laying of all types of communications (water, gas, sewerage).
Loading and unloading bulk, solid and non-standard materials.
Dig a hole for the slab foundation.
Dig a trench under the strip foundation.
The surface is flat and ground plan.
Delete old unnecessary structures.
Tree stumps were uprooted.
Various agricultural work.
Every day, manufacturers of special equipment produce an increasing variety of backhoe loaders. Now the choice of this special equipment is very large, but it can be grouped according to some criteria.
Load capacity and power
All backhoe loaders have a power range from 47 to 81 kW and from 65 to 110 hp. And. The load capacity is affected not only by power, but also by other characteristics. Different types of backhoe loaders are classified by size and weight into light, medium, heavy and heavy.
Small (also known as light) excavators are very light, ranging from 500 kg to 2 tons. This type of equipment is used in confined spaces. This could be narrow alleys or any other place where large equipment cannot move or operate.
Medium backhoe loaders weigh 2 to 4 tons, while large backhoe loaders weigh 4 to 10 tons. Both types are actively used on construction sites, in the construction of roads for digging ditches for communications.
The main areas of application for heavy excavators (weighing more than 10 tons) are large quarries and construction sites with large earthworks.
Chassis and running gear
There are two main types of backhoe loaders: wheeled and tracked. Wheeled backhoe loaders are in high demand because of their ability to self-deliver to jobs. In addition, wheeled excavators are much lighter than tracked excavators. By reducing weight and reducing ground pressure, the wheeled excavator can work even in wetlands.
Crawler backhoe loaders also have their advantages. These excavators move with dignity and work even in complete off-road conditions. They are not afraid of mud, rocks or steep slopes. Where wheeled excavators simply cannot go, crawler excavators work adequately. But for the transportation of such equipment to the facility, it is necessary to use special vehicles.
