The invention provides a lifting mechanism for engineering machinery; the engineering machinery includes an arm frame system; the arm frame system is provided with at least one lifting mechanism and a safety control system thereof; the lifting safety control system includes a lifting force sensor, a controller, a landing leg length sensor and a landing leg angle sensor; the lifting mechanism is one or a combination of a hole type lifting mechanism, a detachable type lifting mechanism and a pulley type lifting mechanism; the hole type lifting mechanism includes a bearing plate, a detachable type lifting mechanism, a positioning plate and a bearing body; the positioning plate is welded on a arm frame of the arm frame system; with utilization of the folding arm frame, the lifting mechanism for the engineering machinery can perform a lifting operation in a narrow area where a telescopic arm frame is difficult to reach; with reasonable utilization of the lifting capacity of a pump truck, the function of the pump truck is expanded; and arm frame overload and pump truck tilting can be prevented.
