Problems solved by technology

The tower crane and the placing boom both superimpose the two functions, and both must rely on the tower body for support, so the scope of work is limited; and after the functions are superimposed, the structure is complicated. If the weight of the heavy object lifted on the folding arm is too large, it will prone to security issues

Abstract

The invention provides an engineering machinery which comprises an engineering machinery chassis as well as a support system, a pumping system and a jib system that are arranged on the engineering machinery chassis, the jib system is provided with at least one hoisting mechanism and a hoisting safety control system. According to the engineering machinery, the pumping system and the jib system realize the pumping function of the engineering machinery, the jib system is matched with the hoisting mechanism so as to realize hoisting function of the engineering machinery, therefore, the jib can carry out pumping operation, and also can be used for hoisting weight objects for all floors in a construction site, so that the engineering machinery realizes multiple functions.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery with pumping and lifting functions. Background technique [0002] Truck cranes, which use telescopic booms, have the disadvantage of limited operating range and can only be constructed in open places, and cannot work in narrow spaces. For example, for lifting weights on a certain floor on a construction site, the upper floor restricts the work of the crane's telescopic boom. space, it is difficult to complete the lifting task. The boom of the tower crane is also mainly telescopic. In addition to being difficult to work in a small work space, there is another defect that the tower crane relies on a fixed column and lacks the flexibility to move at any time, so its operating range is also limited. restricted. The placing boom adopts the folding arm to carry out the spreading, and the lifting device is set on the folding arm, so that it has the spreadi...
