Main advantages

Most efficient cleaning thanks to the suction of the goods down to the lowest layer in the hold which is also even quicker thanks to auxiliary equipment.

The boom can be equipped with a hoist (winch) for an auxiliary equipment (pay loader, skid steer loader or small bulldozer types): it allows to lift it from the quay and to drop it onto the hold bottom.

Usually on wheels but it can be also tracked, this auxiliary equipment will push the products around the suction nozzle for speeding up the cleaning.

Low energy consumption: field reports from VIGAN customer are confirming that optimized design + direct drive of the turbo blower(s) + speed variator (also called frequency inverter) are allowing a power consumption of 0.6 to 0.7 kW per ton.
See above

Contact VIGAN for more details and comparative comments with other alternatives such as grabs or other continuous ship unloading (CSU) systems such as screw or chain for instance.

No spillage: no leakage such as frequently with grabs (clamshells) thanks to the negative pressure inside the suction pipes; conveyor and loading spouts equipped with dust control devices (options).

Low noise: noise of turbo blowers (high frequency waves) can be easily dampened and special noise insulation devices can be installed .

Piping system can be also noise insulated.
