Hi Spec Engineering Ltd.,

Vacuum Tankers


Hi-Spec Engineering manufacture the strongest Vacuum Tankers on the market. We currently manufacture vacuum tankers from 800 gallons (3,600 litres) to 4500 gallons (20,250 litres). All of our tanks use a unique low profile spreading system which will achieve a spreading pattern up to 12 metres wide. The downward splashplate not only increases controllability, but also decreases air pollution and unpleasant smells and helps to ensure all slurry nutrients are directed onto the soil. .

All vacuum tankers are manufactured using 6mm high quality British steel. Internal implosion rings and a collared dished end are provided as standard to ensure the strongest possible construction. All tanks are mounted onto a complete chassis frame to ensure that the tank is completely supported without any weak points. Without this complete chassis, the barrel of the tank can be under increased stress and this will lead to a premature failure or corrosion of the barrel. Hi-Spec Engineering shot-blast all tanks as standard to provide an excellent key for the enamel paint finish, thus giving a high quality long lasting paint finish. Alternatively vacuum tankers can be galvanised to ensure a longer life..

The Hi Spec range of Vacuum Tankers come standard with hydraulic brakes, lights, 6' filler and discharge points, 3' (76mm) sight glasses, a blanked off side fill point, 15ft (4.57metres) of 6' suction hose and a 2½' (63mm) washdown adaptor. All tankers including and above 1,350 gallons (6138 ltrs) also have as standard a 6' quick attach suction hose fitting.

On all tankers from the 2,000 gallon (9,092 ltrs) models fitted with big wheels (23.1-26's / 28.1-26's) a sprung drawbar is fitted as standard. This is designed reduce wear to both the tanker and tractor, it does this by eliminating any shock loads being transferred from the tanker drawbar to the tractor pickup hitch.

The Hi-Spec/Bomech trailing shoe has 34 outlets and a working width of 7.5m with a 22cm row width. It has an overall transport width of 2.55m which meets road legal requirements. Spreading time when compared to a splash plate is very similar but the spread is more accurate and consistent across the complete working width.

Slurry odour is minimized with no drift and grazing of grass can resume quicker than when slurry is spread with a splash plate system, hence grazing periods are extended. With the trailing shoe system, slurry can be applied at later stages of grass growth, compared to a splash plate system which has to be applied at an early stage. There is no increase in power required when compared to an equal size splash plate tanker and maintenance required is minimal.
The Hi Spec/Bomech trailing shoe uses a generation III type macerator with incorporated spring loaded self sharpening hardened knives with automatic reversal. Any foreign materials such as stones etc. are collected within the stone trap which is fitted as standard.Hoses turn up to 180º to prevent remaining slurry leaking out during transport.

Fitted with hardened stainless steel trailing shoes and special rubber boots to prevent and minimise blockages. Minimum surface damage occurs with the Hi Spec/Bomech trailing shoes.
One doubling acting service is all that is needed to operate the Hi Spec / Bomech trailing shoe through an electro-hydraulic control unit.A lifting system is self contained within the Hi Spec/Bomech trailing shoe. The 7.5m Hi Spec/Bomech trailing shoe is of a light weight at just 660kgs with a very simple but strong construction.
