Equipment Equipment

The range of Amphibex AE850P standard equipment includes many interchangeable accessories that provide great versatility found on the amphibious general purpose excavator conceived and manufactured by Normrock. Normrock also offers a multitude of optional accessories. For a complete listing of the standard equipment, consult the technical specifications of the product. For the adaptable options for the Amphibex AE850P that fit your particular needs, contact us.

The cabin

The air-conditioned Amphibex cabin offers all the comfort and visibility necessary for the operation of the amphibious general purpose excavator during long hours. The ergonomic position of the various manipulation arms of the hydraulic controls and GPS navigation system contribute to make the work of the operator comfortable and simple.

In addition, the seat and controllers can move from the left to the right of the cabin to facilitate the visibility and manoeuverability during work near structures.

The C18 Caterpillar engine

Equipped with Caterpillar C18 diesel engine with 700 hp and 765 hp, the Amphibex AE850P general purpose excavators have all the power necessary and are low emisions.

Stabilizers and floats

Its front stabilizers (with floats) and its four anchor piles (adjustable and tilting) also give the Amphibex AE850P all the mobility necessary to move over ground and to adequately position itself for shoreline or marine work. They also give the amphibious general purpose excavator the necessary balance to operate effectively on all kinds of bodies of water.

Propulsion system

Conceived to have maximum power with minimal disturbance, the Amphibex AE850P propulsion system has achieved its goals. It can sail at 5 to 8 knots and is set above the water and its shallow propeller protects marine vegetation and avoids moving the sediment layers deposited at the bottom of the bodies of water.

Positioning system

The Amphibex AE850P positioning system can be fitted with very sophisticated GPS technology, particularly useful when pumping contaminated sediments. Day or night, these systems are used to determine precisely where the amphibious excavator should be.
