An improved carrying assembly is provided for using with, and controlled from, a helicopter to seize and lift immobilized vehicles from freeways and other limited access highways. The carrying assembly may be composed of an integrated and framework having four selectively adjustable vertical leg members, each horizontally positionable one to another, for seizing and supporting the vehicle at appropriate points on its chassis whereby the carrying assembly can engage vehicles of many different sizes and configurations. Control and actuation of each of the different segments of the framework is preferably achieved from within the helicopter, whereby the vehicle targeted from removal can be directly approached from overhead, and whereby the vehicle can be securely seized and lifted without assistance from personnel on the ground.
