- Model 650 - Excavator System for Shore Lines and Marine Environments



Designed for large-scale works, the Amphibex 650 differentiates itself with its power. Excellent for pumping, it also stands out with superior excavation depth. Its great power allows it to meet the needs of the most demanding production. Its size does not affect its agility and versatility. The amphibious excavator is able to perform a variety of work on the shore line and other marine environments. Regardless of the work involved, budgets and work schedules, even the most complex, will be better met with the Amphibex 650.

The Amphibex also boasts a design that allows for rapid mobilization to face any kind of situation immediately. Transportation to the sites is easy using a flatbed truck. On site, the Amphibex 650 uses its stabilizers to move to the shore line of the body of water.

In all kinds of bodies of water, the Amphibex 650 can achieve a wide variety of tasks.

  • Restoration and cleaning of contaminated rivers
  • Dredging (contaminated sediments, sediments, mud or sand)
  • Stake driving
  • Water conduits, pipelines and underwater cable installation
  • Cleaning waste water treatment basins
  • Ice breaking and prevention
  • Vegetation control
  • Exploitation of peat bogs
  • Creation of wildlife habitats
  • Recovery of mining waste, coal ash

The Amphibex 650 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.


Propulsion System
Conceived to have maximum power with minimal disturbance, the Amphibex 650 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.


Stabilizers and Floats
Its front stabilizers (with floats) and its four anchor piles (adjustable and tilting) also give the Amphibex 650 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.


The C18 Caterpillar Engine
Equipped with Caterpillar C18 diesel engine with 700 hp and 765 hp, the Amphibex 650 general purpose excavators have all the power necessary and are low polluters.


The Cab
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 manoeuvrability during work near structures.
