Henning Marine Weed Harvesters

Aquatic Weed & Plant Harvesters

Barge

Catamaran vessels for superior cutting, transit speed and umatched stability. Multiple independently sealed compartments with inspection hatches. Aluminum catamaran hull construction with 4.5 mm / 3/16” wall thickness on Series D-6100 and D-7600. Stainless steel hull with 3 mm / 1/8” wall thickness on Series D-8200 and D-9200 is standard. Stainless steel optional also on all other models.

Cutters System

Horizontal cutters recessed to prevent weed losses. Hidden and protected horizontal cutter motor.  Extra heavy duty cutting parts. Cutter motors protected by bearing load adaptors. Stainless steel base frames and cutter drive brackets and arms.

Conveyors

Conveyor frames in stainless steel. Aluminum side walls. Plastic wear strips under belt tracks are “clip-on” type, will not get bulge and warp in sun light (has allowance to stretch and contract during temperature variations). Drive and idler shafts come with stainless steel insert journals & bearings.

Control Bridge

Aluminum constructed bridges are easily dropped for low clearance underpasses during all modes of operation & transport. HI-LO deck mounted hydraulic lift version on D-6100 and D-7600 Series. Light weight tilt down upper control bridge on D-8200 and D-9200 Series.  Joystick and switches for remote engine and hydraulic controls. No exposed hydraulic pressure hoses. Perfect 360° visibility for the operator.

Power System

Engine and central hydraulic system located on deck far away from the operator for low noise level. No visibility obstruction form upper structure.  Zero splash from propulsion units (as opposed to paddle wheels). Lower maintenance cost. Easy access from dock and on board. High combined performance  compared to equally-sized other weed harvesters and skimmers. Full aluminum enclosures with air spring lift-up hood.

Propulsion System

Twin propulsion system. No need to detach for road transport. Stainless steel deployment down legs. Variable speed, bi-directional control.  Hydraulic drive and power steering. Vertical hydraulic lift for shallow water approach. Kick-back suspension to prevent underwater impact damage. No wrap, weed free, heavy duty helix propellers
