The apparatus includes closable jaws for securement to the clamping brackets, and arms including a carrier member for holding and positioning the capping member. The apparatus can be moved, controlled and manipulated at a safe distance from the pipe, and includes a rod mechanism for rotating and closing the jaws to engage the clamping brackets around the pipe, and a further rod mechanism for raising, lowering and rotating the arms to properly position the capping member within the open end of the pipe. Preferably, the apparatus is provided with a device for spraying the clamping device and the pipe with water, chemicals or any other suitable liquid material for cooling same.
