The new, so-called Mega PST, based on the 2. In recent years the market for SPMTs — the original 2. Currently, manufacturers from Germany, France and Italy offer container-sized SPMT-systems that have a gross capacity of 40 to 44 tons 36 to 40 metric tons per axle line. According to Goldhofer, engineers took a different approach with their design of the Mega PST by incorporating market requests to increase capacity per axle line. The new design offers a gross capacity of 56 tons 50 metric tons per line, a mere 10 to 14 tons extra compared to current SPMTs on the market. Of course it should be remembered that the roadway to be travelled can support the increased axle loading and that the load itself has a large enough bearing area.

It is based on the 2, mm container width and has an innovative 50 tonnes capacity per axle line. Drastic change has characterised the SPMT market in recent years as three of the world's largest suppliers were acquired by one owner. The original 2, mm wide transporter has four wheels per axle line and computer controlled and electronic multi-directional steering. Current offerings from manufacturers in Germany, France and Italy are container-sized SPMT systems with a gross capacity of 36 to 40 tonnes per axle line.
Goldhofer has taken a different approach with its design of the Mega PST by incorporating market requests to increase capacity per axle line. The new design offers a gross capacity of 50 tonnes per line, 10 to 14 tonnes more than current SPMTs on the market. It should be remembered that the road to be travelled needs to support the increased axle loading and that the load itself needs a large enough bearing area.
This also applies to the frame and other components of the Mega PST. The manufacturer claims a sufficient safety factor in the design, for example, by using higher capacity tyres, with sufficient spare capacity, that allows for short-term extreme peak loads that are unavoidable in day-to-day heavy haul operations. Goldhofer claims that the Mega PST is superior to conventional self-propelled modular trailers on all criteria. The maximum steering angle offers plus and minus degrees, sufficient to provide all steering patterns, including crab and rotating on the spot.
The hydraulic suspension offers a stroke of plus and minus mm from a standard loading height of 1, mm. Power packs up to hp run the hydraulic system, including the hydrostatic propulsion, and comply with the latest engine exhaust requirements, including EPA III in North-America.
Goldhofer claims that the new Mega PST transporter will contribute substantially to turnover, especially because of its unique features giving advantages over similar systems. With the new Mega PST the manufacturer expects further growth in, especially, markets for hydrostatically driven self propelled transporters. In addition to the traditional heavy haul market, Goldhofer expects the Mega PST to be of interest to the ship building industry. According to Goldhofer, the first major orders for the new type comprise more than axle lines.

Goldhofer launches Mega PST
Some say the SPMT is the unsung hero of the heavy transport industry. The module is also now available with what Goldhofer is calling the Speedrive option, which allows the drive axles to be operated in freewheel mode. This means transportation companies can tow the module under full load thus speeding up operations. The tractive power of the module has also been increased, weighing in at kN. They will primarily be used to transport large plant components for the energy industry and equipment for refineries. It now has almost double the tractive power of the previous version, coming in at hp. When the vehicle is in towed mode, rather than self-propelled mode, there is no oil flow in the hydromechanical drive system.
