PT44 MAESA, High Mobility Utility Truck

PT44 MAESA Series “O” High Mobility Utility Truck is designed to transport cargo and soldiers. The Maesa has a payload capacity of 4,000 Kg. The Independent Suspension gives measurably improved cross-country speeds for same vehicle weight, power/weight ratio and tyres. An average speed gain of up to 1.5 times that attainable with conventional beam axle vehicles can be expected.

Under-axle clearance is greater than on conventional vehicles with no differential bowl protrusion or other obstructions.
The cargo bed can be equipped with an optional bench seat kit for transport of soldiers. The bench seats can be constructed either of a wooden or a non-wood material and attach to the cargo bed side rails. A canvas and bows kit is available to keep soldiers and cargo protected from the elements.

Pacific Technology Independent Suspension System

Its highly advanced configuration isolates road forces, thus ensuring maximum load stability and comfort for the driver. The absence of chassis twist and the exceptional long wheel travel provide outstanding vehicle performance under even the most adverse terrain conditions.

Wheel travel from over 250 mm is available, depending on the individual application of the system. The Maesas wheel travel is 300mm and as a result, the vehicle can absorb greater road forces while maintaining better road contact with improved dynamic stability – especially during severe manoeuvres – with greater traction and significant advantages in the speed of the vehicle.

Independent suspension provides better road contact and maximises traction, especially in marginal conditions. Dynamic stability is greatly improved and progressive roll provides the driver with far better feedback of vehicle behaviour. Many accidents with conventional vehicles happen because the driver at the front end, of a flexible chassis in critical situations, has no idea that the back end is rolling dangerously and can, unknowingly, approach the point of roll-over.

A flexible chassis also causes continual alteration of steering geometry on a conventional vehicle. The combination of rigid chassis and independent suspension which allows fine tuning of the steering produces neutral to moderate under-steer, increasing at higher lateral acceleration. As a result, the driver has a safer, more predictable steering response. Any or all axles are steerable without modification.



The Department of Defence of the Republic of Indonesia choose PT independent suspension for the basis of their 4X4 Tactical Vehicle. The decision to choose the high mobility PT Independent Suspension does not come as a surprise. As well as providing greater speed and stability off-road, the performance and handling on the highway is much more like that of a car than of a traditional commercial truck.

Originally the Maesa was designed with the same suspension system as fitted on the Australian Bushmaster produced by ADI (Australian Defence Industry), but it was dropped because it was consider too cumbersome for Maesa.
