Abstract

The invention discloses a self-loading and unloading foldable tower crane, which relates to a tower crane. The self-loading and unloading foldable tower crane solves the problem that the existing jib-fixed tower crane is inconvenient to set up and detach, and the construction period of building works is delayed. In the tower crane provided by the invention, a base and tower body combined mechanism is arranged on the ground; a first jib, a second jib and a third jib are orderly and horizontally arranged at the upper end of the base and tower body combined mechanism of the tower crane from leftto right, and the first jib is perpendicular to the base and tower body combined mechanism of the tower crane; the base and tower body combined mechanism of the tower crane is connected with the first jib through a lower support rod, the first jib and the second jib are connected in a foldable and expandable manner through a single-rope dual-lifting point horizontal jib retracting and folding mechanism, and the second jib and the third jib are connected in a foldable and expandable manner through a single-rope three-segment horizontal jib turnover buffering self-lock device. The self-loading and unloading foldable tower crane is suitable for being used in the building works.

Description

technical field [0001] The invention relates to a tower crane, in particular to a self-loading and unloading foldable tower crane. Background technique [0002] The tower crane has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. At present, most of the tower cranes used in my country's construction industry are old-fashioned traditional fixed boom tower cranes, and the boom and tower body are installed on the tower crane as a whole. In some crowded places, the application of old-fashioned traditional fixed boom tower cranes in building construction is often clumsy, and there are a series of disadvantages. It is inconvenient to erect and dismantle, which delays the construction period of construction projects. Contents of the invention [0003] The purpose of the present invention is to solve the problem of inconvenient erection and dismantling of the existing ol...
