Description
Technical field
The utility model relates to technical field of engineering machinery, particularly relates to the stabilizer plate device of a kind of harbour movable crane.
Background technology
Harbour movable crane is a kind of high-mobility, multipurpose, wheeled vehicle weight-lifting equipment being widely used in the facilitated transition of the handlings such as harbour container, groceries and bulk goods.Owing to having good manoevreability, applicability and economy, be used widely in harbour abroad.
Consider the deadweight of harbour movable crane and the large feature of work range, its Work places is the harbour at harbour or trestle mainly.For medium and small tonnage harbour movable crane, every bar movable supporting legs, by single leg disc and earth surface power transmission, can meet its stability requirement, can not have an impact again to harbour or trestle work structure.
But for large-tonnage harbour movable crane, because rated load weight is large, if each supporting leg is by single leg disc and earth surface power transmission, damaging influence certainly will be produced to harbour or trestle work structure.
Therefore, how improving the ground contact area of large-tonnage harbour movable crane leg disc, increase the stability of its work, needing the problem of solution with regard to becoming those skilled in the art badly.
