  • This is a 9 cubic metre salt spreader / highway gritter with optional brine tanks which can operate as a salt only gritter and/or pre-wet gritter. This machine is for lorry mount on medium to large carrier vehicles(17 tonne plus carrier vehicles or greater). The total length of the gritter from spinner to hopper wall is 5 meters (16 feet 5 inches). These gritters are suitable for 17 tonne or larger carrier vehicles with a body 15 feet or more in length.
  • The STP-70  is a stand-alone gritter with its own independent hydraulic system powered by its own donkey engine to go on any lorry vehicle with a plant body with a rapid mount/demount capability with the roll on/roll off features supported by  a set of fold-away parking legs for short or long term storage.
  • Installation to a lorry body requires max 30 mins as there is no need to integrate the gritter with the lorry hydraulics or PTO power shaft nor modify the chassis. It is a roll on/roll off solution. All that is needed is a 24 v electric supply and it can be deployed rapidly to ride upon any suitable lorry. This solution can be put into action from storage in just the same time it takes to load it on a lorry and fill it with grit.
  • This gritter comes will a fully integrated pilot box to give comprehensive multifunction control and and information feedback to the operator in the carrier vehicle cab.
  • All elements of the spreader are corrosion resistant, including bolts, connections etc. Components are either stainless steel or galvanised mild steel or galvanised and painted steel or 355 steel with a triple layer paint coating.
A multi-year maintenance program is provided by Agritrend LTD along with a schedule of detailed preventive maintenance activities with extended warranty offered, subject to the completion of a maintenance log.

Engine:

The spreader will be powered by an onboard donkey engine and will have its own independent hydraulic reservoir, pump, motors and hydraulic pipework distribution circuits. Integration of this solution with your truck we be a matter of using standard safe and appropriate mechanical restraints for fast roll-on/roll-off. We will provide appropriately certificated straps and/or chains for securing the gritter to the lorry body.

We use an HATZ 2G40 engine - link

Info:

Capacity:

The hopper capacity is 9cu.m. Side-members are made from 6mm steel. The hopper sides are 3mm steel, and the chassis 6mm steel. All welding is continuous.

Brine tanks:

Modular tanks with capacity 2700 litres fitted for pre-wetted salt or brine solution. Tanks have brine level sensors which alert the control box and operator when the tank level is low. The tanks have interconnects for rapid levelling and come complete with bulk-head wash plates.

Warranty and Response:

Parts are kept in the UK at the Gerrards Cross location to the West of London and at the Pronar rapid response centre in Poland. Hot standby versions of the gritter are kept in the UK during the winter season for fastest possible response.

At Agritrend we operate with two mobile phone holders in senor positions who are able to give technical advice and to marshal a rapid response to any fault or warranty or spares situation or to any contingency requiring our advice and for product support and spares. This is a 24/7/365 service which is always available.

We will provide a training day covering the operation of the machine and the care and maintenance schedule with a member of the technical team from the Pronar factory and a member of the Agritrend support team in the UK.
