Active Dragheads
Active Dragheads
VOSTA LMG’s active dragheads offer the highest production rates possible, even in compact soils and at varying dredging depths. The pressure nozzles can be arranged at the visor carrier and/or at the visor itself according to customers' preferences. The hydraulic power pack can be installed on deck or as integrated part of the draghead. Various control systems are available, enabling efficient use of the active draghead. The basic version of the control system includes continuous position indicators and switches for bridge desk mounting. Advanced dredge control and automation systems automatically adjust the visor position and water flap. Visor position can be controlled, for instance, with constant position, pre-selected grab depth or cylinder force and water flap position to suction pressure at the draghead.
