Rapidly erected small crane

Abstract

The invention provides a rapidly erected small crane. The rapidly erected small crane comprises an underframe, a tower body, a jib and a raising device, wherein a rotation support is arranged on the underframe; an upper rotating table which can rotate relative to the underframe along with the rotation support is arranged above the rotation support; the upper rotating table is hinged to the lower end of the tower body; the upper end of the tower body is hinged to the jib; the raising device is mounted at the front end of the jib; the rear end of the jib and the upper rotating table are fixed through a pull cable; a jacking system is arranged on the upper rotating table and is a hydraulic mechanism; and one end of the jacking system is hinged to the upper rotating table while the other end of the jacking system is hinged to the tower body. Various components of the crane are simplified; the small carne is transferred rapidly, is convenient to erect and can adapt to hoisting construction in small space; domestic market vacancy is filled; the integral design level of the industry is increased; and the rapidly erected small crane has outstanding substantive features and remarkable progress.

Description

technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a fast erecting small crane. Background technique [0002] Cranes are indispensable construction equipment in the field of building construction. The domestic lifting equipment used in building construction is mainly divided into two categories: one is tower cranes, and the other is construction hoists. In some small building construction fields, due to the limitations of the site and construction period, it is often impossible to erect tower cranes, or the use of large equipment is not economical, and the cost of each shift is high, and the erection and movement of construction elevators are inconvenient, making it difficult to meet construction requirements. Therefore, for small building construction, there is an urgent need for a lifting device that can be easily transferred, small and light, and quickly erected.
