[0002] A truck crane is a type of crane mounted on a standard or custom automobile chassis, with a separate driving and lifting cab. The chassis' performance is equivalent to that of a truck of the same gross vehicle weight, meeting the technical requirements for road vehicles and enabling unimpeded travel on all types of highways. This type of crane typically features two operator cabs, one for loading and one for unloading, and outriggers must be extended for stability during operation. Capacities range widely, from 8 to 1,600 tons, and the number of axles on the chassis can range from 2 to 10. It is the most produced and widely used type of crane.

[0003] Compared with the existing technology, there are problems: when using a truck crane, it is necessary to use support legs to support it to ensure the balance of the crane during lifting operation. The existing crane balance support mechanism is relatively cumbersome to use, and the flexibility of the crane support operation is poor. The support mechanism cannot be divided into zones and adjusted according to lifting needs, resulting in poor crane balance support effect, which in turn affects the stability of the crane lifting operation. For this reason, we propose a truck crane balance support mechanism to solve the above problems. Utility Model Content
