The modern construction market is filled with a huge amount of the most diverse equipment that facilitates any work. This type of equipment includes a crane-manipulator - a machine that makes an invaluable contribution to the construction process. Such equipment has a rather complex design, differs in functionality, dimensions and power. All the details regarding the successful selection as well as the best crane manufacturers can be found below.

The crane-manipulator is a cross between a conventional automatic crane and a truck. Thanks to this technique, the most complex installation, construction and earthworks are carried out.
It is worth noting that any crane-manipulator is considered an expensive pleasure, since its complex design, as well as further operation, involves a lot of financial costs.As a rule, professional machinists are hired to manage such equipment. If the loader crane has sufficient power, and a specially trained person is behind the wheel, then the described machine can perform the following tasks:
To successfully choose a crane, you must carefully study its functionality, technical characteristics and design features. However, first of all, the following rules should be observed:
Having dealt with the basic rules for choosing a crane, you need to familiarize yourself with the design features that will ensure the successful completion of the work.
Given the design of the loader crane, it becomes clear that this equipment can be installed on any construction machine. However, in such cases on the construction site, the machine will operate with minimal maneuverability and stability. To avoid undesirable consequences, it is better to get a special tractor or flatbed truck. The cost of this hybrid will be higher, but high performance in work and lifting of heavy loads is guaranteed.
The first thing you need to do is to study the load capacity of the machine. Loader cranes that will lift, for example, 10-15 tons, are not recommended to be installed on light trucks. Otherwise, the lifting equipment will simply roll over. The described factor also has the other side of the coin - you should not take heavy lifting chassis if the work involves transporting or lifting household appliances.
It is necessary to pay attention to the arrow based on what types of work will be carried out.Any modern crane-manipulator has a face value of 2-8 units. Naturally, the more edges in the arrow, the more the machine will be able to lift, and the more expensive it will cost. Accordingly, for greater reliability and power, an 8-sided crane would be ideal, and for lifting small weights, a 2-sided one.
Those loader cranes that have a built-in winch have a huge number of advantages compared to conventional CMUs. First of all, it is worth noting the manual decrease in the landing speed of the weight. Such a function is simply necessary in cases where work is carried out with fragile materials.
How long the winch cable will be depends on the type of work being done. If any load falls into a deep hole, then a long rope will be needed for successful implementation. However, the cost of this element will be too high, so before buying, you need to carefully consider the nature of future work.
For the current year, there are more than 40 CMU manufacturers around the world, the vast majority of which belong to the domestic market. However, not every manufacturer can offer a really worthy option with an optimal price-quality ratio. The following is a list of the best manufacturers that produce equipment that is used around the world.
The American company Grove began its existence back in 1947, so this manufacturer can be safely considered one of the oldest. At the moment, the organization's construction equipment is in great demand around the globe. The first lifting equipment was developed by 1950, and after 44 years.the company has already been producing multifunctional equipment for construction work with might and main, in connection with which it received an international quality certificate.
The assortment of the organization includes a wide variety of hydraulic and mobile cranes, the length of which is up to 60 meters, the lifting height is up to 120 meters, and the lifting capacity is up to 400 tons. Given the technical characteristics of cranes, we can safely say that Groove is not in vain one of the first places in the world market. Cranes-manipulators of the American company are regularly used on the largest construction sites for the construction of skyscrapers. It is also worth noting that the organization is engaged in the production of cranes for the military industry. As for the present, Groove, together with Mercedes-Benz, is engaged in the manufacture of truck cranes.
During the production of loader cranes, innovative technological processes are used. For example, one of the advantages of the equipment is the independent Megatrak lighting, which comes with the drive chassis, provides maximum maneuverability and enhances the stability of the boom during transportation, as well as the working process. Also noteworthy is the Twinlock locking system, which allows you to achieve high productivity, lifting capacity and huge reach. The hydraulic system Hydraulic and Les is responsible for changing the angle in the loaded state, which provides rotation from 5 to 50 degrees. Thanks to this approach, the crane-manipulator quickly copes with the tasks.
The ECOS electronic unit acts as a control link, which not only makes turns more convenient, but also allows you to collect all the necessary data regarding the operating parameters of the boom.A wide cab viewing angle (50 degrees) is provided by the Hydraulic Cab tilt system.
Another oldest manufacturer of lifting equipment began its existence back in 1895. Since that moment, the Japanese company has been manufacturing all types of construction equipment, and therefore has taken one of the leading positions around the world. 1940 was a significant year for the organization, because from that moment its own production of wheeled and tracked cargo vehicles began. In the future, this ensured the creation of full-fledged loader cranes, without the use of third-party equipment.
By the end of the 1960s, the company moved into the production of mass-produced truck cranes, as well as drainage and cleaning equipment. KATO hydraulic lifting machines began to be mass-produced in the early 1970s and soon gained mass recognition in the international market. Particular attention should be paid to the Jumbo NK 750 model, which is considered the largest truck crane in the world. The rest of the company's product range includes all-terrain cranes, cranes for urban use and excavators.
The booms of KATO cranes have a length of 4 to 6 meters. Thanks to this, Japanese technology is regularly used on large construction sites. The carrying capacity of this equipment is up to 20 tons. The main advantage of these loader cranes is high maneuverability and compactness. Machines are easy to transport in urban and populated areas.
One of the largest manufacturers of ground and underground equipment has its own production points in more than 10 countries on 3 continents. When it comes to construction equipment manufacturing, LIEBHERR boasts the most diverse product range of any of the companies on this list. The production sites produce concrete mixing plants, pipelayers, automatic concrete mixers, wheel loaders, crawler loaders and bulldozers, hydraulic excavators, dump trucks, hydraulic cranes, mobile cranes, tower cranes and loader cranes.
The high quality of LIEBHERR products is determined by the use of proprietary technologies. Absolutely all important elements of construction equipment are manufactured directly in the company itself. For example, crane and truck control systems, drive technology, transmission, electrical and electronics, engines, and hydraulic systems. The production departments are engaged in the manufacture of such small parts, such as bearings, hydraulic cylinders, that other popular companies turn to LIEBHERR for help.
Since 1947, the Swedish company HIAB has been developing loader cranes for heavy machines.As for the present, in 2019 the concern produced about 15,000 units of manipulator lifting mechanisms. A distinctive feature of this construction equipment is high precision and build quality. The reach of the longest crane boom is 8 meters, thanks to which the equipment is able to lift the load to a height of 32 meters.
The latest models of the Swedish concern (XS 622-625) are equipped with an advanced control system. Upgraded hydraulic elements provide smooth lifting and landing of the load. The load moment of the described equipment is 75 Tm. Modern models are equipped with advanced electronics, which is responsible for the automatic extension of the boom. The only drawback is the low speed of the arrow.
The Danish construction equipment manufacturer Hojbjerg Maskinfarik A/SHMF has been operating since 1954. The equipment of the company differs in reliability and simplicity of a design. A distinctive feature is the use of their own technologies, which were developed by the engineer and part-time founder of the organization Arne Jensen. The range of the concern is not as large as it is more diverse. For example, on the international market you can find miniature versions of HMF-50 loader cranes, as well as heavyweights ODIN and THOR, capable of lifting 28-30 tons.
Most models are equipped with a smooth-running boom system, making the equipment ideal for working with fragile materials.Also noteworthy is the intelligent control system, which is characterized by automation of its own production. The described node is responsible for extending the boom with a heavy load, therefore, in emergency cases, the system will independently stop the work process.
The best manufacturers of loader cranes are considered mainly foreign companies. If the financial situation allows you to purchase reliable and high-quality equipment, then you should give preference to Japanese and German products. Also, during the selection of construction equipment, design features, characteristics and functionality should be taken into account.
