The 6-line configuration of Trail King's new Modular Hydraulic Transport System (MHTS), with a 375,000-pound (170 tonne) load capacity, is the first off-road transport system to be engineered and manufactured exclusively in the USA, the company said.

While its stirrups and side plate design are engineered to be compatible for use with existing brands of line trailers, the MHTS offers features not found on models offered by other manufacturers, according to Trail King. An example is the air system, which includes drain fittings on each tank and an air dryer, and air tanks that are easily accessible for maintenance or removal and replacement.

In addition, the steering arms of the MHTS are positioned over 'dished' cross members so that they are more easily accessible for repositioning or replacement. To prevent build-up of dirt and grime that can interfere with steering arm performance or make repositioning more difficult, the steering arm mounting bosses are raised, not recessed.

The hydraulic system, which uses steel hydraulic lines throughout, is driven by a 20 hp (15 kW) water-cooled diesel self-contained unit for quieter operation. It is externally mounted so the hydraulic reservoir can be larger. The company said it is large enough to allow up to 20 lines. All functions are controlled by wireless remote with wired pendant backup.

The self-locating tow bar has special notches in the tow bar plate that line up with the tops of the stirrups for alignment, making attachment of the tow bar to the unit more convenient, the company said. An air-activated locking system is designed to quickly, conveniently, and securely lock the tow bar in the transport position.

Other features and standard equipment include: a 55 degree maximum steering angle; a hydraulic stirrup pin for easy connect and disconnect to other lines; clearance lights, and brackets for strobe lights, flags, and wide load signs.
