Discover our TRI-S tanker range
TRI-S Tanker
The TRI-S tankers are available with capacities from 4000 to 5000 gallons (18,184 to 22,500 litres) and use three large high-speed commercial axles to support the load.
The TRI-S range is engineered to deliver unmatched manoeuvrability. To achieve this, the rear axles are equipped with standard passive steering. In addition, our tankers come fitted with a standard Jurop 11,000-litre pump, ensuring reliable and efficient filling.

Jurop Pump
A Jurop vacuum pump with a capacity of 11,000 litres is fitted as standard on all TRI-S models.
Jurop is a high-quality pump designed and manufactured in a modern factory in Italy. As a result, Jurop pumps are recognised as the fastest and most powerful vacuum pumps available today.
Each pump is assembled according to Jurop’s methodical standards and thoroughly tested and inspected.
Driven via PTO, Jurop pumps provide the most efficient method for filling or emptying the tanker as standard.
Jurop pumps have a worldwide reputation for exceptional quality and minimal maintenance.
Parts and servicing are available locally through your nearest Hi-Spec dealer, and the premium-quality construction ensures an extremely long service life.

Tyres
TRI-S tankers offer a large load capacity, with this weight distributed across three axles and six tyres.
The TRI-S models come standard with front and rear steering, and the tyre selection plays a key role in enabling smooth travel over the ground without causing damage.
Equipped as standard with 600/50-22.5 BKT flotation tyres, the tankers can travel over soft soils without compacting them.
The unique tread design allows the transport of very heavy loads at low pressure, while at the same time reducing soil compaction and preventing damage.
For road transport, we recommend the 600/50 R22.5 BKT FL693M Ridemax.

New Feature: Axles
The TRI-S models offer substantial capacity distributed across three axles.
These axles are non-recessed, allowing for maximum load capacity.
TRI-S uses high-speed commercial axles with rear steering for improved manoeuvrability, making it ideal for road transport or field spreading.
