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.

Abstract

The invention discloses a lorry-mounted crane, a control system thereof and a lorry-mounted hoisting and conveying vehicle. The control system of the lorry-mounted crane is used for providing the flexible selection on control positions for operators and improving the operation accuracy and work efficiency of the lorry-mounted crane controlled by the operators. The control system of the lorry-mounted crane provided by the invention comprises multiple groups of linkage mechanisms which are arranged in parallel and are used for controlling different hoisting movements, wherein each group of linkage mechanism comprises side control handles on at least one side of the lorry-mounted crane and upper control handles above supporting legs of the lorry-mounted crane, and each side control handle and the corresponding upper control handle are in linkage through a connecting rod 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 ...
