Embodiment Construction

[0035] Such as figure 1 As shown, the present invention discloses a foldable and quick-install tower crane, which includes a slewing platform 1, a liftable tower body, a tower body lifting and folding mechanism, a foldable cross arm and a cross arm folding mechanism. The lower end of the tower body is movably connected with the slewing platform 1, and the other end is movably connected with one end of the cross arm; the tower lifting and folding mechanism is respectively connected with the slewing platform and the tower body, and is used to control the movement of the tower body. Lifting and folding; the cross-arm folding mechanism is respectively connected to the cross-arm and the tower body, and is used to control the folding of the cross-arm.

[0036] Such as figure 1 , Figure 4 as well as Figure 5 As shown, the liftable tower body includes a tower body 4 and a tower body jacket 3 , the tower body 4 is located in the inner cavity of the tower body jacket 3 and moves al...

Abstract

The invention discloses a foldable fast-loading tower crane comprising a rotation platform, a tower body capable of being lifted, a lifting and folding mechanism of the tower body, a foldable cross arm and a cross arm folding mechanism, wherein one end of the tower body is movably connected with the rotation platform, and the other end is movably connected with one end of the cross arm; the lifting and folding mechanism of the tower body is respectively connected with the rotation platform and the tower body and used for controlling the lifting and the folding of the tower body; and the cross arm folding mechanism is respectively connected with the cross arm and the tower body and used for controlling the folding of the cross arm. The invention has the advantages that the structure is simple; the more manufacture cost is saved than the traditional self-lifting tower crane; the tower body can be stretched and shrunk in the jacket of the tower body; the tower crane can lift enough height for low-storey buildings of about 6 storeys so as to solve the problem of insufficient lifting height of a vehicle-mounted crane; the tower body and the lifting cross arm of the fast-loading tower crane of the invention are in a folded state in a consignment state or an off state; and the fast-loading tower crane has the advantages of convenient transportation and good market prospects.

Description

technical field [0001] The invention relates to the field of hoisting and transporting devices, in particular to a foldable and fast-installing tower crane applied to low-rise buildings with a construction floor height of 20 to 40 m. Background technique [0002] In recent years, rural and small town buildings have developed from a single-story structure to low-rise buildings with 2 to 3 floors or 3 to 6 floors. At the same time, some low-rise urban buildings also need to be renovated and maintained. For buildings with a construction floor height of 20 to 40m, if the traditional self-elevating tower crane is used, it will be overkill and increase the cost. But as adopting its lifting height of truck-mounted crane, there is obviously not enough problem. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a collapsible and quick-install tower crane for the deficiencies of the prior art.
