A truck crane is a crane mounted on a common automobile chassis or a special automobile chassis, and its driving cab is provided separately from the lifting operating room. The advantage of this type of crane is that it is maneuverable and transfer quickly. The disadvantage is that you have to support your legs when you work, you can't load, and you don't work on soft or muddy fields. The chassis performance of a truck crane is equivalent to that of a truck with the same total weight of the entire vehicle. It meets the technical requirements of road vehicles and can be used on all types of roads. Such cranes generally have two control rooms for loading and unloading, and the legs must be extended to maintain stability during operation. The lifting range is from 8 tons to 1600 tons, and the number of axles of the chassis can be from 2 to 10. It is the largest and most widely used type of crane.
There are many types of truck cranes, and their classification methods are also different. The main ones are:
Classified by weight: light truck cranes (with a lifting capacity of less than 5 tons), medium-sized truck cranes (with a lifting capacity of 5-15 tons), heavy-duty truck cranes (with a lifting capacity of 5-50 tons), and super heavy-duty truck cranes (lifting weights) At 50 tons or more). Due to the use requirements, the lifting capacity has increased, such as the production of large truck cranes of 50-1200 tons.
According to the type of outrigger: frog type leg, x type leg, h type leg. The frog-type leg span is 0. It is only suitable for cranes with smaller tonnages; the x-type legs are prone to slippage and are rarely used; the h-type legs can achieve larger spans, and the stability of the whole machine is obvious. The superiority, so the hydraulic cranes produced in China mostly use h-shaped legs.
According to the transmission mode of the transmission: mechanical transmission, electric transmission, hydraulic transmission.
