Backhoe - a clever tool for excavation works

bit of history and theory

Shovel reverse - an element of the production system shovel.Digging bucket provided motion downward and toward the machine at a level below the installation.The main purpose - is the excavation of ditches, trenches, pits development.The principle of the backhoe was invented by an engineer from Holland Makarov in 1763, but in the life of this idea was realized only in the nineteenth century with the advent of shovel engineer V. Otis.

Note!There is an inverse and shovel.The first type is required to perform work above the level of installation of the machine, the second - to work below.

There are two kinds of backhoe: mechanical and hydraulic.The first produced with the system moving the cable traction.The bucket is rigidly mounted on the rod handle, which hinges fixed at the top of the boom.Movement of the lifting or tensioning rope handle is rotated.

Just digging is due to pull the bucket driving mechanism.When the bucket is pulled, it is removed from the bottom and with the platform is developed to the point of discharge.The hydraulic shovel consists of the same elements as the manual except for the rack, which supports a rope.In addition, the boom is driven cylinders.

differences between the hydraulics and mechanics

backhoe able to perform work on the development of the soil above its installation, but with less efficiency than shovel excavator.Working backhoe cycles are differences that depend on the type of drive.Differences hydraulic excavators:

• Arrow dug into the pit along with the installation of the handle position;
• Filling the bucket is due to its rotation relative to the handle;
• Arrow vyglublyaetsya simultaneously with the turn of a handle and steer bucket;
• platform deployed with the working equipment;
• unload the bucket due to its rotation relative to the handle.

Mechanical diggers follows:

• The pit deepened both the boom and the stick;
• fill the bucket relative to the boom by turning the handle to the side of the machine;
• Boom and Stick vyglublyayutsya simultaneously;
• Unloading takes place by turning the handle in the direction of the arrow and the excavator.

Note!Shovel feedback allows precise positioning of the bucket relative to the ground and the vehicle loaded.

Backhoe in another area

The principle of the backhoe is not only used in the excavators.This technology has been successfully used for loading.Backhoe loader is a self-propelled vehicle maintenance, which consists of a tractor, front shovel and backhoe.With its small size and portability, it is widely used on medium-sized construction sites and excavation.

This loader is able to perform a variety of tasks in the field of construction, material transport, drilling, excavation, backwash and asphalt laying of roads.When replacing the bucket on the other tool can grind and break the stone and concrete.There are also types of trucks with a sliding bottom, which make loading faster.

Note!The indisputable advantage of mobile loader is its simplicity and ease.You do not need a long time to learn to begin to control it.
