SEPARATOR OBSTACLE COURSE

MOUNTAIN HEAVY TRANSPORT (MHT) RECENTLY TRANSPORTED AN OVERSIZED SEPARATION TANK FOR COMPASS MINERALS IN OGDEN, UTAH USING A GOLDHOFER THP/SL 6 HEAVY-DUTY MODULAR TRAILER. ANDY ADAMS REPORTS.

Compass Minerals, North America’s biggest producer of sulphate of potash and magnesium chloride, uses the tanks to store its chemical products. MHT’s task was to transport a separator tank, nine meters high and eight meters in diameter, along a 4.5km route consisting of hairpin bends and gravel roads. It also had to cross a railway, pass under a high-voltage power line and negotiate an overhead pipeline.

MHT had to minimise the forces acting on the separator to avoid damaging its internal epoxy coating. A Grove GMK 7550 crane was used to place the 26-ton tank on a six-axle heavy-duty Goldhofer modular trailer towed by an Oshkosh M1070 tractor. Weight distribution was a challenge, with a high centre of gravity near the closure. The cargo was secured with eight chains, two at the bottom and two on either side of the cover.

A three-man team was required. The driver was accompanied by a spotter in the cab and an operator at the rear of the trailer so that every manoeuvre could be observed from several perspectives. The first part of the journey was on public roads. They were closed to traffic as the width of the cargo necessitated driving on two lanes. Passage under the high-voltage power line was executed with the help of the local utility company which used poles to temporarily raise the cables. The last obstacle on the journey was an overhead pipeline six meters above the ground. A crane was used to lift the separator over the pipeline and set it back down on the trailer on the other side.
