Amphitruck 4×4

 

 

 

The Amphitruck is the first amphibious vehicle designed to meet the exacting requirements of both military and civilian applications, and the first to offer the combined functions of a fully seaworthy boat and a practical truck with high load capacity and speed.

The Amphitruck’s advanced design combines operational ease with flexibity of application and offers important advantages:

The Amphitruck is easy to drive
The rudder is operated by the steering wheel, simplifying land/sea transitions, and the only additional controls are for propeller drive, air intake and bilge pumps.

Mobility and speed
on land distinguishes Amphitruck from other amphibians. Away from the beach head it is a highly manoeuvrable wagon with a top speed of 55mph. The Amphitruck incorporates a reversing hydraulic marine gearbox.

Excellent visibility
is enabled by the short downward sloping bow and high driving position.

A large loading platform
provides an excellent workspace with fittings for lashing unwieldy loads securely and attaching safety rails for use in open configuration.

Tail-gate loading
is essential in a conventional wagon, but Amphitruck is unique in offering this feature on land and at sea.

Ample storage capacity
beneath decks is accessible through hatches in the loading platform and foredeck. Space is provided below the main deck for fitting of ancillary equipment. The foredeck stowage is designed for marine equipment and may also be reached from the cab in heavy weather.

A strong, corrosion-resistant structure
is ensured by using G.R.P. for the cab and hull and checkerplate aluminium for the decking.

Ease of maintenance
Most work can be completed speedily from within the hull with access through the deck hatches, although the cab may be removed for major tasks such as engine or gearbox changes.

Amphitruck applications address civilian problems which manufacturers of military amphibians have largely ignored. Now there is an amphibious vehicle with the high mobility and exceptional load capacity to solve those problems in wide-ranging situations.

Island Services - Communities too small to justify a ferry, or too awkwardly placed to accept one, will benefit from Amphitruck. It is economical, requiring fewer operatives, and can operate in shallows or at low tide. In addition. Amphitruck can drive directly from the slipway to an on-land delivery point.

Pollution Control – Palletised equipment can be rapidly loaded and transported to a pollution site. The tail-gate allows the deployment of a containment boom with ease and simplicity, and pollutants can be moved onshore directly without the hazard of transfer from boat to wagon. Amphitruck also gives access to gentle shelving shores unreachable by wagon or boat.

 

Fish farming – The time and effort of loading a boat is removed by transferring food and material to Amphitruck, onshore and moving directly to the pen in one operation. Almost any beach can be used for a sea launch, obviating the need for a slip or jetty.

Coast Guard/Customs – The Amphitruck can patrol remote and inaccessible beach areas on sea or land and once beyond the surf line, can launch a fast boat from its tail-gate for a sea intercept.

Sea Defence Maintenance – This growing requirement often requires access to long shelving beaches which are inaccessible to shore or sea-bound vehicles. Amphitruck can place men and materials directly on site.

Inshore rescue – Amphitruck can speed to the rescue of people involved in accidents or shipwrecks, or cut off by water in tidal flats. It is also cheaper to operate and less weather dependent than a helicopter.

Airport Rescue – Amphitruck can act as a Crash tender on land or deliver assistance to offshore accidents where airports are built on recalimed land or are next to the sea.

Cable Laying – Cables may be deployed from shore to shore without transferring equipment to a boat. A bow thruster may be fitted for accurate positioning.

Harbour Fire Tender – Amphitruck can reach a fire on land or water, making it a versatile fire applicance at locations where two vehicles would otherwise be needed.
