• Présentation

The AE400E is the compact model of our range of Amphibex dredgers. Surprising and extremely versatile, it’s ideal to complete a variety of works on the shores and underwater. The AE400E is easily transportable and excels at performing tasks in restrained areas, but its size does not affect its power. Equipped with CAT engines, all our dredgers are designed to last and perform in the most extreme conditions, ensuring unparalleled reliability. In addition, we are proud to manufacture all our Amphibex with the best technological advances to ensure maximum respect of the environment.

Flood prevention and ice breaking

The Amphibex AE400E is a world calss ice breaker and is used in many places for flood control. In the majority of cases, the use of the Amphibex AE400E makes it possible to avoid using explosives which can be detrimental to the environment. Several techniques can be used to break ice.

Drainage work

The Amphibex AE400E is a very effective device for drainage operations. Its mobility on land and water, anchorage and stabilization equipment, added to its wide range of interchangeable accessories (bucket chipper, bucket pump, conventional bucket, rake and side discharge spout) give it a distinct advantage over traditional drainage machinery.


Shore line interventions

The Amphibex AE400E differentiates itself through its shore line work. Able to accomplish a large wide variety of operations (pipe installation, cleaning of the banks or vegetation control), it involves only minor disturbances where the use of traditional general purpose excavators would have created severe damage.

Equipment Equipment

The range of Amphibex AE400E 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 AE400E 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 positioning of the various manipulation arms of the hydraulic controls and the GPS navigation system contribute to make the work of the operator comfortable and simple.

The C9 Acert Caterpillar engine

Equipped with Acert C9 Caterpillar engine, the Amphibex AE400E general purpose excavators have all the power necessary to be successful. These engines are compact, light and are low emisions.

Stabilizers and floats

Its front stabilizers (with floats) and rear (adjustable and tilting) also give the Amphibex AE400E all the mobility necessary to move over ground and to adequately manoeuvre for work on the shore line or on water. 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 AE400E 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 AE400E 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.
