Compared with the truck crane, the difference between the two is mainly in the following two aspects. The chassis is different. The truck crane uses a standard or special vehicle chassis, and the tire crane uses a special chassis, and its wheelbase and wheelbase are properly matched, so that the stability is good, and it can lift goods on a flat ground, but the walking speed is very low, so Suitable for working in a cargo yard.
The number of cabs is different - the tire crane has only one cab, which is located on the turntable, and the various mechanisms of the crane are operated from this cab; while the truck crane has two cabs, one is on the turntable, and the lifting, slewing and luffing are controlled. The mechanism, another in front of the crane, controls the travel and steering of the crane.
The crawler crane is a cantilever slewing crane that mounts the working part of the crane on the frame. This kind of crane can work under the condition of poor road surface, has good stability, and can work without opening the outriggers, but the running speed is low (generally no more than 6km/h), and the road surface will be damaged when driving; in addition, the maintenance operation It is also more complicated, the accessories are not easy to solve, and it is subject to certain restrictions in use. Generally only applicable to buildings and construction sites.
Portal crane, also known as gantry crane, is a full-slewing cantilever crane mounted on a portal base that walks along the ground track. It is one of the general lifting equipment for ports and station garages. . The working mechanism of the gantry crane mainly includes four major mechanisms: hoisting, luffing, slewing and running.
Through the combination of lifting, luffing and slewing mechanism operation, the lifting and moving of goods can be realized in a large annular cylindrical space, and the working position of the whole machine can be adjusted through the operating mechanism, so it can be used in a large operating range. Meet the needs of transporting goods.
