Problems solved by technology
[0005] The defect of the existing technology is that the selection of the operator's manipulation position is inflexible. When there are many heavy objects to be lifted or heavy objects need to be lifted accurately, the operator's field of vision is limited and he cannot observe The lifting of heavy objects in the cargo box greatly affects the accuracy and work efficiency of lifting operations

Embodiment Construction
[0056]In order to provide operators with more flexible control position selection, and improve the operator's accuracy and work efficiency in manipulating the truck-mounted crane, the embodiment of the present invention provides a truck-mounted crane control system, a truck-mounted crane and a truck-mounted crane. transport vehicle. In this technical solution, the side joystick on the side of the truck-mounted crane is linked with the upper joystick above the outrigger, and the operator can flexibly choose the manipulation position. When the operator manipulates the upper joystick above the outrigger of the truck-mounted crane When lifting the heavy objects in the cargo box, you can observe the lifting situation, so the accuracy and work efficiency of operating the truck-mounted crane are greatly improved. The present invention will be described in detail below with specific embodiments and in conjunction with the accompanying drawings.
[0057] Such as Figure 1 to Figure 6...

The invention discloses a control system of a truck-mounted crane, a truck-mounted crane and a truck-mounted lifting transport vehicle, which are used to provide operators with more flexible control position selection, and improve the accuracy and work efficiency of the operators in manipulating the truck-mounted crane. efficiency. The control system of the truck-mounted crane of the present invention includes multiple groups of linkage mechanisms arranged side by side and respectively controlling different types of lifting actions. Each group of linkage mechanisms includes: a side control handle located on at least one side of the truck-mounted crane, and a The upper control handle on the top of the outrigger, each side control handle and the upper control handle realize linkage through the link mechanism.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control system of a truck-mounted crane, a truck-mounted crane and a truck-mounted crane transport vehicle. Background technique [0002] Truck-mounted cranes, also known as truck-mounted cranes, are usually assembled on the chassis of trucks. They are multi-action hoisting machines that can vertically lift and horizontally carry heavy objects within a certain range. The truck-mounted crane usually includes a support device and a boom mounted on the support device through a slewing device. A truck equipped with a truck-mounted crane is called a truck-mounted crane, which can realize the dual functions of lifting operations and material transportation. [0003] In the prior art, the truck-mounted crane is usually installed between the driver’s cab and the carriage, and the control of its boom mostly adopts the linkage operation method of left and right two points ...
