An Article Tells You The Detailed Classification Of The Crane And The Method Of Choosing It!

 Crane is a large-scale machinery used in many construction projects now. It helps companies in many aspects to complete the handling of some large-scale materials. So what are the classifications of cranes? Mainly truck type, tire type, all-terrain type, And special styles and so on. Not only do you need to know the detailed classification of cranes, you also need to understand the method of choosing it. In today's article, I will give you a detailed introduction to the classification of cranes and the method of choosing cranes.

　　The classification of cranes:

　　Crane can be divided into many types according to the difference of use and structure, and different types of cranes also have different uses. Let’s take a look at the classification of cranes together:

　　1, truck crane

　　 The crane is installed on the chassis of a general-purpose or special-purpose vehicle. The performance of the low plate is equivalent to that of a truck with the same total vehicle weight. It meets the technical requirements of road vehicles and can be used on all types of roads without obstruction. This type of crane is generally equipped with two control rooms for up and down, and outriggers must be extended to maintain stability during operation. The lifting weight can range from 8 tons to 1,000 tons, and the number of axles on the chassis can range from 2-10.

　　2, tire crane

　　 The lifting part is installed on a special pneumatic tire chassis. A single engine is used for getting on and off the vehicle, and the driving speed is generally no more than 30 kilometers per hour, and the width of the vehicle is relatively wide, so it is not suitable for long-distance driving on the highway. It has the function of lifting and traveling without outriggers, and is suitable for lifting operations in places with limited moving distances such as freight yards, docks, and construction sites.

　　3, all-terrain crane

　　 is a high-performance product that combines the characteristics of truck cranes and rough terrain cranes. It can not only transfer quickly and travel long distances like a truck crane, but also meet the requirements of working on narrow and rugged or muddy grounds, that is, fast driving, multi-axle drive, all-wheel steering, three steering modes, off the ground Large clearance, high climbing ability, no need for outrigger lifting and other functions, it is a very promising product.

　　4, special crane

　　 A special crane developed to accomplish a specific task. For example, crane-wheel rescue vehicles mounted on off-road vehicles or armored vehicles for tactical and technical support for mechanized forces; road wrecker vehicles for handling traffic accidents, etc., all fall into this category.

　　How to choose a crane:

　　Different construction environments have different requirements for cranes. If you want to help the construction project complete faster, you need to choose a suitable crane. The following editor will introduce to you:

　　1. When the hoisting project requires heavy lifting capacity, high installation height, and large range of lifting operations, crawler or tire cranes can be selected according to the existing mechanical conditions. If the ground is soft and the driving conditions are poor, a crawler crane is more suitable; if the ground within the working range is not allowed to be damaged, a rubber-tyred crane is better.

　　2. When the construction conditions are restricted and the crane is required to travel with a heavy load, it is dangerous to travel with a heavy load. If it is necessary to operate, the lifting weight should meet the requirements of the machine's instruction manual. Crawler or tire crane can be selected. Rubber-tyred cranes have better maneuverability; crawler cranes have higher lifting stability.

　　3. Under normal circumstances, crawler cranes should be used for ordinary single-layer assembled structures with a large amount of hoisting work. Because crawler cranes have low requirements on the road surface, they are convenient for luffing and driving, and they can be driven with load. Truck cranes are less destructive to the road surface, and are quick and convenient to go to the hoisting location. They are suitable for hoisting assembled structures located in urban areas or with a small amount of work.

         For hoisting projects located in remote areas, long distances, or poor road conditions, simple hoisting equipment such as single-leg pull rods, herringbone pull rods, mast cranes, etc. can be selected, which can often be started earlier to meet the schedule requirements and cost Low.

　　 The above is the classification of cranes introduced by the editor, and the method of choosing cranes. If you don’t know enough, you can always consult us!
