VMI’s pontoons include v-brakes, internal cross bracing and multiple baffled compartments for extra rigidity. The pontoon seams are continuously welded and factory tested for leaks. Each individual compartment is foam filled for floatation safety. The bottom of the pontoons are provided with a skid channel to allow the dredge to be pulled into place.

Four Independent Hydraulic Pumps
Features a fully variable high-torque hydraulic cutter drive
allowing the operator to adjust the speed for maximum
material uptake depending on the condition
of the material being dredged.
VMI uses a recessed impeller to provide maximum free flow and per-formance in thick, viscous slurries. A recessed impeller allows the passage of large diameter solids reducing the potential for clogging. The pump is located directly behind the cutter head suction intake to provide maximum pumping efficiency. Each pump features a unique seal system eliminating the need for packing to reduce maintenance. The pump speed is fully-variable thanks to a hydraulic drive system coupled directly to the pump shaft.
Cummins Power
Full-Width Flow-Through Suction Cutter Head
Provides increased head for pumping long distances
and up high elevation changes.
Provides maximum material
uptake by providing suction
across the full width of the cut-
ter head and through the cutter
cage. A convenient suction
clean-out is located in front of
the pump suction for easy
removal of large
debris.
Treble Sheave Traverse Winch System
The winch drive provides substantial grip on the cable while minimizing wear. Our cable guide design allows you to attach and detach the dredge from the traverse cable without removing the cable from its anchors. Cable guides are mounted to the front and rear of the dredge to mini-mizing skewing side to side in cross wind or water flow conditions.
Interchangeable paddle and cutting teeth allow you to
choose any combination of teeth to meet your dredging
needs.
VMI dredges are equipped with four independent hydraulic pumps to provide ample flow to all hydraulic components without starvation. All continuously operated dredging functions are equipped with variable speed so that you can optimize between engine speed and hydraulic operation speeds. Enhanced filtration and dedicated hydraulic tanks are used to extend the life of all hydraulic mechanisms.
Cummins diesel engines are provided standard due to their reputation for dependability and long lasting service as well as their availability of parts and service worldwide.
