The classification of mobile cranes
Mobile crane according to its operation mode, the performance characteristics and applicable scope, can be divided into four types: crane, tyre crane, crawler crane and mobile crane. The mobile crane is the most widely used car crane (1) crane truck crane is modified with automobile chassis parts or used to install hoist special chassis for running part of most using elastic suspension axle. The car crane USES different driving rooms in the state of driving and lifting. It has the characteristics of fast moving speed and high maneuverability, and it is suitable for the rapid transfer of the field in the long distance. The crane can not be carried on a crane, and the length of the body is large, so the performance is poor.
the operation of the tyre crane cranes use special chassis, axle for rigid suspension, can be suspended load, getting on or off using the same cab. Because the wheel is similar to the wheelbase of the tyre crane, it can guarantee the stability of the tilting, and increase the mobility. It also has good through sex, can be in the range of 360 ° full weekly assignment. The tyre crane can be carried along with the driving, the operation is adaptable, it is suitable for the construction site, the station, the pier and so on relatively stable job site
The crawler crane is a moving crane which is running part of the crawler and its supporting actuator. Compared with the first two kinds of cranes, the working principle of the other institutions is basically the same except that the walking part is replaced by the caterpillar. Due to the large crawler grounding area, but also in the loose walking on the road, it has a large surface adhesion, strong climbing ability, small turning radius (even can turn in place), don't need a supporting leg when working, driving can be hoisted load, etc. search (4) special floating crane refers to the mobile lifting equipment which is constant in the work object or in the field. It is used as a door type tyre container crane for lifting containers, a high-altitude operating car on the chassis, and rescue crane.
