Basics of long reach or high reach excavators

Long reach excavators and high reach excavators are digging machines with an extended boom that is longer than the typical excavators. A long reach excavator is built to expand the working range or operating radius of the digger so that the excavator can reach higher, deeper and farther. The long reach diggers are widely used in many working conditions, including mining, wharfs, warehouses, building demolition, dredging canals or rivers, flood relief and other special conditions. Compared with the structure of a typical excavator, the long reach excavator differs in the following aspects such as main boom, extended boom, boom cylinder, extended boom cylinder, excavator bucket and bucket cylinder. The extended boom is attached on the top of the main boom and a corresponding cylinder is added to the working device, with a cylinder control system added in the cabin so that the operator can control the extension and retraction of the boom. 

The long reach excavators have many advantages. For instance, the long reach excavators can significantly increase the working efficiency with high mechanization thus save more labor cost for the customer. To use long reach excavator in construction can greatly ensure the safety of the operator because, with the extend boom the operator can keep a longer distance from the object and reduce the danger of being hurt especially in housing demolition projects. More importantly, the long reach excavators are more practical, capable of meeting the requirements of many demanding jobsites.
