Wheeled crane

Abstract

The invention relates to the field of engineering machinery, and discloses a wheeled crane which comprises a telescopic arm, an arm-folded rotary-type driving cabin, a revolving table as well as a lower vehicle chassis, wherein the revolving table is installed on the upper end of the lower vehicle chassis; the telescopic arm is installed on the upper end of the revolving table; and the arm-folded rotary-type driving cabin is installed on the upper end of the revolving table and is installed at one side of the telescopic arm. The wheeled crane further comprises a folded arm, a driving cabin and a driving device, wherein the folded arm is installed at the right side of the telescopic arm at the heading direction of the crane, one end of the folded arm is connected with the driving device, the other end of the folded arm is connected with the driving cabin, and the folded arm rotates synchronously with the telescopic arm. The wheeled crane provided by the invention is compact in structure, flexible in running and beautiful in appearance; the specific arm-folded rotary-type driving cabin changes the installation mode and the internal operation functions of the traditional driving room, an operation room is omitted, and the production cost is lowered; the arm-folded rotary-type driving cabin also can provide humanized operation experiences; operators can get on and off more conveniently; revolution left and right as well as up and down amplitude of variation motion can be realized; and the wheeled crane has a better working visual angle.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a wheeled crane. Background technique [0002] With the gradual deepening of the wave of urbanization, China is entering the era of metropolitan circles. The city, urban and rural areas have been integrated. In the process of urbanization, due to the special use environment with narrow urban construction space, new requirements have been put forward for product flexibility, compactness, and convenient operation. [0003] Wheeled cranes are usually equipped with independent cabs and operating compartments, and the operating compartments also require matching mounting brackets, occupying a certain space on the frame, which not only affects the layout of other components or accessories, but also increases the length and width of the crane. And the driver's cab itself has many available but underutilized spaces and functions except that it has the function of operating the crane...

AI Technical Summary

Problems solved by technology

[0003] Wheeled cranes are usually equipped with an independent driver's cab and operating room. The operating room also needs supporting mounting brackets, which occupies a certain space on the frame, which not only affects the layout of other components or accessories, but also increases the length and width of the crane. In addition to the function of operating a crane that a general car cab has, the cab itself also has many available but underutilized spaces and functions.
