H:/sbt/nte o n/NRPortbl/DCC/SBT/8624177_L.ocx-14/10/2015 - 45 A VEHICLE FOR INDUCTION HEATING A BENT PIPELINE SECTION A vehicle 400 for induction heating a bent pipeline section, wherein the vehicle comprises a helical induction coil 404, a first wheel chassis 410a supporting wheels 422 proximal a first end of the induction coil and a second 5 wheel chassis 41 Ob supporting wheels 422 proximal a second end of the induction coil. The wheels are arranged to guide movement of both ends of the induction coil through a tubular inside face of a bent pipeline section. The first wheel chassis and the second wheel chassis are coupled to each other by an elongate bar 440 passing though the induction coil. The first wheel chassis and the second wheel 10 chassis are each coupled to the bar by a respective bearing 442a, 442b. The bearings permit pivoting movement of the first wheel chassis and second wheel chassis in relation to the bar in directions normal to a longitudinal axis of the bar.
