SELF-CONTAINED UNDERWATER EXCAVATOR
LISIE
LISIE stands for Light Subaquatic Innovative Excavator.
DISCOVER LISIELISIE: Light Subaquatic Innovative Excavator is an excavator weighing just 4.7 tonnes, robotized and marinized by WATERTRACKS.
LISIE has been developed by WATERTRACKS to evacuate sediments and other materials from depths of 100 meters and more, with no restrictions on the water level. It can operate in narrow and/or confined spaces, close to sensitive civil engineering structures.
LISIE is equipped with two types of caterpillar track, enabling it to move easily over all kinds of terrain.
Equipped with a TOYO submersible pump with a capacity of 150m3/hour, LISIE works in discharge mode right up to the water surface; depth has virtually no effect on the pump’s performance curve.
Features
Rapid implementation and low mobilization costs:
LISIE can be deployed in a single day with just a trailer and its mobile control station.
Agility and versatility:
LISIE is capable of carrying out a multitude of tasks in narrow environments and close to sensitive structures, thanks to its multitude of sensors, articulated arm and turret orientation.
3D positioning and real-time work monitoring :
LISIE enables the operator and the customer to view LISIE’s position and the progress of work by bathymetry in real time.
This enables precise operation for targeted work.
No operators on the water:
All our robots are controlled from a control room on land.
This allows us to work independently of the water level, but also to work 24/7 in complete safety without having to encroach on the water surface.
