    • A portable blast head rigging apparatus is disclosed which is particularly suited for use in cleaning the sides of large storage tanks. The rigging employs a travel car having a winch mechanism thereon. By means of a cable connected to the top of the tank the car crawls up the side of the tank to the top where it is pivoted into a position from which it can travel around the entire circumference of the tank. Once in place the travel car hoists a rigging into position against the tank side suspended from the travel car. The blast head is then moved up and down within the rigging by operation of the travel car winch mechanism and the travel car is repositioned periodically to permit treatment of the entire tank.
