The invention provides an engineering machinery hoisting device and belongs to the technical field of engineering machinery hoisting, the engineering machinery hoisting device comprises a support, a hanging assembly, a hook assembly and a lifting assembly, the hanging assembly is arranged on one side of a workpiece, and the hook assembly is arranged at the output end of the lifting assembly and used for hooking the hanging assembly; the lifting assembly is installed on one side of the support and used for driving the hook assembly to move up and down, when the hook assembly moves upwards, a workpiece can be taken away from the ground through the hanging assembly, and when the hook assembly moves downwards, the hooking state of the hanging assembly and the lifting assembly can be released, and therefore the workpiece is placed on the ground. Compared with the prior art, after the workpiece is hoisted to the target position, the hooking state of the workpiece does not need to be manually relieved, and then the
