Typically used for excavation work over longer distances, for example, for all those hard-to-reach areas, and to maximize production. While externally it is a single bucket excavator, the design of a long reach excavator can withstand higher loads, resulting in greater excavation force and lifting capacity. This technique allows excavation at greater depths of increased complexity, i.e. excavating larger volumes of soil and moving it over greater distances, than a conventional crawler or wheeled excavator. This type of excavator, therefore, has several times the performance of those with a shorter, conventional boom.
These excavators are capable of carrying out work in remote and inaccessible areas. The machine can cope with tasks that exceed the capabilities of other specialist equipment. However, efficiency can only be achieved with adequate operator experience.
Historically, excavators have been used since ancient Egyptian and Roman times as a means of mechanizing the dredging of riverbeds and canals. A longer boom is precisely what is needed for the mechanized dredging of riverbeds and canals. Therefore, the origins of the long-reach excavator go back to antiquity.
Long Reach Arm and Booms
This type of machine is nothing more than a simple bucket excavator. At the same time, however, it has major design differences from other excavators. The main difference is the long boom, which extends the range of applications, allowing access to hard-to-reach areas, special project orders, and other challenging tasks. These machines are designed for the toughest working conditions and can be seen not only in excavation work over longer distances but also, for example, in the removal of topsoil from the surface of building rock, the formation of high-level embankments, the construction of land reclamation systems, the moving, loading or unloading of building materials, and the cleaning of various reservoirs.
Long reach excavators are needed for all kinds of work projects that require access to hard-to-reach areas. It is therefore important not to make a mistake when choosing this excavator to carry out the task at hand. In this case, a mistake can have serious consequences, ranging from cost overruns to unfinished projects.
The first step you need to take is to assess the technical specification of the long reach excavators, i.e. to determine the parameters on which you will choose the machine. In order to make sure that the investment in the machine pays off and that no additional costs are incurred, it is essential to assess the technical specification, which is the main criterion for selecting a long reach excavator.
In addition to power, the digging depth, maximum bucket size, and other criteria must be considered.
The next step is to contact your sales representative to find out:
how far away the machine is from a service center;
what experience has been gained in servicing this equipment;
whether essential spare parts and maintenance tools (bearings, filters, etc.) are stocked locally, and what is the shortest possible lead time to obtain the necessary spare parts; and
if the warranty period can be calculated on the basis of the hours worked.
When choosing a long-reach excavator, most buyers are interested primarily in the price of the machine. In fact, the price of a long reach excavator is an important factor for buyers when purchasing specialist equipment, but it is not the right deciding factor. When choosing a long-reach excavator or any other equipment, you should look not only at the price but also at other features.
