Several major categories of cranes

Cranes different ways depending on the installation can be divided into
    1, truck cranes
    Truck  Steel crane   the crane mounted on the chassis of the vehicle on the general or special low disk performance is equivalent to the total weight of the same vehicle truck, road vehicles comply with the technical requirements, which can be on the road in all kinds of passage. Such cranes generally available, and get off two control room, legs stretched out operations necessary to maintain stability. From the weight of a large range, from 8 tons to 1,000 tons, the chassis number of axles, from 2 to 10. Is the largest output, the most widely used type of crane.
    2, the tire crane
    Lifting part of the installation in a special crane chassis of a pneumatic tire. Combined with an engine on and off, speed is generally not more than 30KM / H, vehicle width is wider, it should not travel long distances on the highway. Has no legs and hoists with lifting function for garages, docks, construction sites and other places with limited movement distance hoist operation.
    3, rough terrain cranes
    Developed in the 1970s as a crane whose lifting crane tires similar function can also be performed without legs and hoists with lifting. The difference is the form and structure of the chassis chassis structure by a unique brought improved running performance. Such  overhead gantry crane  are mounted on the chassis engine, the chassis has two axles and four large diameter off-road tread tires. Four wheel drive wheels and steering wheel are when the muddy uneven transfer station on the site, the four wheels to transmit power, that four-wheel drive to improve through the muddy ground and uneven road capabilities. When on a flat surface at a faster rate when traveling with only two wheels on the front axle or rear axle drive to reduce energy consumption. Random file of the crane, with said four-wheel drive 4 × 4, 4 × 2 represents 4 there are two axle wheels are wheels. The models suitable for small venue operations. Enabling continuous infinitely variable, in the case of road resistance mutation does not turn off the engine, and thus greatly facilitates the driver's operation. The rough terrain cranes can be a performance extended, powerful and flexible tire cranes.
    4, all-terrain crane
    Is a combined truck cranes and rough terrain cranes characteristics of high-performance products. It can not only transfer as fast as cranes, long distance running, but also to meet in a narrow and bumpy or muddy pitch on the job requirements, namely traveling speed, multi-axle drive, all-wheel steering, three kinds of steering mode from the ground gap, high climbing ability, you can do leg lifting and other functions, is a very promising product. But the price is higher, use and maintenance require a higher level.
5, special cranes
    To accomplish a specific task and the development of special cranes.bridge crane For example: for the mechanized implement tactical and technical safeguards used, mounted on armored vehicles in off-road vehicle or lifting wheel rescue vehicle; to deal with road traffic accidents wrecker, etc., fall into this category.
