The history of Liebherr began in 1949 with the design and installation of the first tower crane. Its founder was Hans Liebherr, whose goal was to create a powerful family business for the production of technology. The distinctive characteristics of the crane, and, consequently, the main components of the company's success, are the mobility of equipment, ease of installation and reasonable cost.


Liebherr is today a powerful company with branches all over the world. The total number of employees reaches 35 thousand people. Liebherr has several main areas - the production of construction machines and high-quality, functional, innovative technical products aimed at the customer.


Liebherr's scale is truly impressive. In order to obtain maximum results and full return, the company is divided into separate companies. All 130 companies operate independently of each other, which enables complete control of the global market. Liebherr is still a family business. The holding company Liebherr-International AG is located in Bühle (Switzerland) and is managed by Wili and Isolde Liebherr, who successfully continue the family business.


In 1938, Hans Liebcher became the direct heir to the family business. Despite his young age, 23, he immediately understood the needs of post-war Germany and began productive work in the chosen direction. Mobile and stationary tower cranes, heavy-duty construction equipment have been the main products of the company for decades and made Liebherr the leading manufacturer of the time. In 1949 an industrial exhibition was organized in Frankfurt am Main, where the Liebherr tower crane won the main prize. This event became significant in the history of the company, after which its name became worldwide.


Today Liebherr is still active in the construction industry. Lifting, tower and port cranes, powerful quarry trucks, concrete mixers, excavators, the main parts of railway cars and the aviation industry, innovative technical equipment of all kinds - technology, the design and production of which, as before, is the main focus of the company. Liebherr products are popular and in demand both in the professional environment and in the homes of ordinary consumers. Refrigeration equipment of this brand has long won the hearts of customers all over the world.

The first Liebherr refrigerator was designed in 1954. Its main advantages are reliability, comfort and ease of use. The next refrigerator model, created on the basis of advanced technologies and supporting the FrostSafe system, appeared 12 years later, namely in 1966. The refrigerator provided for the presence of four sections located vertically. The sections were cooled using a separate evaporator. New refrigerator models have been introduced by Liebherr every decade, and each has been incredibly successful. 1971 was a real discovery for the world of technology. It was then that Liebherr presented its first electronically controlled refrigerator. Electronics made it possible to control the temperature in the chambers (including the freezer) and maintain the temperature regime from -24 to -18 degrees.

Liebherr specialists did not stop there, and already in 1976 they proposed an improved model with a digital temperature indicator. After such an overwhelming success, the work of the company has become even more productive. Refrigerator models underwent frequent modifications, they became powerful, stylish, "smart", gradually approaching modern perfection. In 1978, the GS 5211 refrigerator was developed, with an audible indicator. The indicator was activated when an unacceptably high temperature in the freezer compartment was reached. The presence of this signal helped to maintain the optimal temperature in the freezer, which is paramount for the proper storage of, for example, meat and fish products.

A novelty in 1980 was the development of cold accumulators in Liebherr refrigerators and freezers. The presence of such a battery made it possible to keep the cold in the cell after a power outage for 80% longer than in any other refrigerator. The innovation was warmly received in the global market. The cold accumulators were easily removable, which made it possible to take them with you if necessary. With the birth of this battery, a new idea was born - the development of portable refrigerators.

1987 is a time of real sensations. Liebherr, having made another breakthrough in technology, made possible the "No Frost" system, thanks to which housewives could forget about the depressing and unpleasant process of defrosting the refrigerator! In 1989, refrigerators with the "No Frost" system became even more sophisticated, because along with comfort, they also became economical, i.e. consumed the minimum amount of electrical energy.

   The first ten years after the end of World War II for a large part of Germany were marked by large-scale restoration work. Hans Liebherr was at the time running his parents' construction company in southern Germany and was constantly faced with an acute shortage of equipment and tools needed to build residential buildings. As a result, in 1949 he, together with a group of designers and artisans, developed the first mobile slewing tower crane, marked TC 10. The benefits of the new crane were easy transportation and quick installation on virtually any construction site. Simultaneously with the development of the TC 10, Hans Liebherr founded an engineering plant in Kirchdorf an der Iller, where the serial production of the new cranes was organized. Thus, a small construction company was transformed into an independent engineering company.


The company has been manufacturing crawler dozers for over thirty years. During this time, the machines have improved and received new qualities and capabilities. The Liebherr PR 734 bulldozer belongs to the fourth generation and is distinguished by its high performance, reliability, economy and comfort. Parts and elements that make up the machine are produced directly at the factory, undergo careful control and only after that are installed. Thus, the equipment is capable of working in difficult conditions, while possessing a high motor resource of the units.

In 2017 Liebherr started production of its largest crane ever. The HCL offshore crane will have an increased lifting capacity. Its applications include the construction of wind farms, the dismantling of offshore platforms and lifting operations in the oil and gas sector. This model will be the largest crane ever produced by Liebherr. In 2017, Liebherr received an order for the supply of an HCL crane for the specialized vessel Orion. At an outreach of 50 m, this giant will be able to lift cargo weighing up to 3000 tons to a height of 170 m.
