The invention discloses an engineering machinery hoisting device. The engineering machinery hoisting device has the technical scheme that the engineering machinery hoisting device comprises an ascending and descending device, a support frame and second box bodies, wherein the ascending and descending device comprises a first support column; the first support column is fixedly arranged on the innerwall of the right end of the support frame; first box bodies are fixedly arranged at the two ends of the inner wall of the first support column; a first hydraulic cylinder is fixedly arranged on theinner wall of each first box body; the output end of each first hydraulic cylinder is inserted and connected to the inner wall of a first accommodating plate; the top of the first accommodating plateis connected with a telescopic plate; a second hydraulic cylinder is fixedly arranged on the inner wall of each second box body; the output end of each second hydraulic cylinder is inserted and connected to the inner wall of a third box body; a third servo motor is fixedly arranged on the inner wall of each third box body; and the output end of each third servo motor is inserted and connected to the inner wall of the telescopic plate. The engineering machinery hoisting device has the beneficial effects that a product is supported through the telescopic plate, so that swinging of the product during ascending and descending is avoided, and the product falling danger is also avoided.
