The History of Gehl Excavator

The Liebherr family business was founded in 1949 by Hans Liebherr. The great success of the first mobile, easy-to-mount and low-cost tower crane predetermined the future direction of work. Today, Liebherr is one of the world's largest manufacturers of construction equipment and a recognized provider of high-tech, customer-oriented products and services. More than 135 companies on all continents with more than 43 thousand employees are part of the Liebherr Group.

The conveyor life of an excavator is five to ten, and sometimes more years. The debut of the new generation of G7 crawler excavators, which includes the models R926, R930, R934, R938 and R945, took place in 2019 at the BAUMA trade fair in Munich. Machines weighing from 26 to 45 tons are capable of solving a wide range of tasks in various industries and industries.

 

30 ton series

There are two basic models in the line of modifications of the new generation: thirty-ton R930 and forty-ton R938. The rest are modifications derived from them. Due to the large number of interchangeable parts of the machines of the new line, operators can reduce the range of spare parts and consumables, and thereby reduce the volume in working capital warehouses. For example, the R926 and R930 excavators differ mainly in weight, which depends on the type of implement and rear counterweight. Of course, differences can also lie in the used undercarriages.

40 ton series

The R938 model has a lighter version of the R934. It also belongs to the forty-ton class. The excavators have the same power units, but thanks to the Common Rail electronically controlled power system, they have different power settings: 220 versus 200 kW. A derated motor on a lighter machine has an advantage in resource, as it works with less load, and therefore wears out less. The same can be said about hydraulic pumps. They are identical, but on the R934 they do not work with the maximum load.
