Abstract

The invention discloses a suspension arm bearing device which comprises a supporting hydraulic cylinder used for supporting a suspension arm and an energy accumulator in hydraulic connection with the supporting hydraulic cylinder, wherein the energy accumulator is used for energy storage when the suspension arm compacts the supporting hydraulic cylinder. Moreover, the invention further discloses a suspension arm bearing system and a crane. The suspension arm bearing device can relieve rigid impacts produced by the suspension arm.

Description

Technical field [0001] The invention relates to the field of engineering machinery, and in particular to a boom carrying device, a boom carrying system and a crane. Background technique [0002] In recent years, China's construction crane industry has achieved rapid development. As a multi-action crane, cranes are developing towards intelligence and large-scale development. After digesting and absorbing foreign advanced technologies and independent innovation, the crane industry in my country has continuously optimized its product structure and significantly improved its social benefits. [0003] Among them, the boom is one of the important components of the crane. The cargo can be lifted to a certain height through the boom, and the inclination angle of the boom can be changed to achieve the purpose of luffing, thereby increasing the working range. figure 1 Shows a structural schematic diagram of a truck-mounted crane in the prior art. The truck-mounted crane includes a boom 1, a...
