Loader crane – description, types, selection
A truck equipped with a crane-manipulator has long become a common sight on literally every construction site. Without this special equipment, it is not easy to undertake loading, transportation and subsequent unloading of all kinds of building materials – pallets with bricks, cement and paving slabs, machine tools and almost everything else. As a real replacement for a truck crane from SMEs as a “universal move,” they are used for repair, restoration, road, pipe, landscaping work, on low-rise construction sites, as well as in limited areas where a regular truck crane simply won’t work.
In the ever-increasing race for speed and low cost, machines that can handle a number of tasks simultaneously are becoming increasingly important, which is why on-board crane rentals have eclipsed the increasingly important rental orders of conventional truck-mounted cranes, which are in demand. What kind of technology this actually is, where it is used and whether it has any disadvantages, we will consider further.
Contents of the article:
in the usual sense, a loader crane is a device installed on board a truck, with the help of which loading and unloading operations of varying complexity are performed. The main types of their systematization include 2 categories:
- In the air – supplied to a simple vehicle such as KAMAZ, MAZ or Japanese trucks Hino, Mitsubishi, Daewoo and others. Used for transporting goods, building materials and for transporting people to heights (using a special wicker device);
- Low-frame – with a low loading platform with or without side walls. The main task is the transportation and evacuation of vehicles, equipment, equipment, built-in high-altitude systems (changing cabins, containers, swimming pools).
A separate group includes all-terrain loading cranes, the main purpose of which is increased maneuverability outside urban conditions and the likelihood of working on moving floors, while with the usual appearance of similar devices they have every chance of realizing that they only work on hard floors or asphalt surfaces.
If anyone tries buy the rights to the manipulator , then we must not forget that this does not comply with the legislation of our country.
What is a crane in terms of advantages and disadvantages in operation?
The fundamental superiority of such special devices is the trivial savings in foreign currency when purchasing or renting. If previously 2 devices were required to sort, load and unload goods and subsequently transport goods, now with such data you can overcome a truck crane with a side once.
In addition, a loader crane is an excellent option for working in cramped warehouse conditions; not all outstanding characteristics here depend on the type of loader crane (CMU). The latter are available in 2 forms:
- Rope cranes are more identical to conventional cranes; they have a rigid telescopic boom (extends like a spinning rod). Following in their footsteps, their advantages include the ability to work through obstacles – ditches, fences; increased visibility of the CMU operator; vertical movement of goods. Disadvantages – there is a possibility of the machine overturning; to minimize such risks, crane installations are equipped with booms; it is necessary to ensure the likelihood that they will come very close to the submerged object;
- Hydraulic manipulators. They have a key advantage of their own system – the likelihood of the arrow bending; They literally do not wobble during transportation. Due to the lack of special equipment and the high cost of purchasing running boards, there is a rather small selection of possible jobs.
Basic characteristics of loader cranes
These forms of cars are distinguished by a number of characteristics: the load capacity of the boom, the length of its reach, the load capacity of the side. In situational and personal situations, small and rather small vehicles with a boom lifting capacity of 1 to 3 tons are more often used. Medium (3-5 tons) and giants from 5 tons and above more often rent enterprises to complete more important tasks.
