Description
VMI MD-615 Horizontal Dredge
NEW condition – available now!
The VMI MD-615 Horizontal Dredge is a reliable, transport-ready cutter suction dredge ideal for midsize dredging tasks. Its combination of robust cutter head, hydraulic winch propulsion, and recessed impeller pump provides effective sediment removal with manageable transportability and serviceability. It is a midsize, one-piece transportable cable-driven cutter dredge designed for efficient sediment removal in environments such as lagoons, ponds, lakes, marinas, and small waterways. It’s part of VMI’s horizontal dredge lineup — machines known for durability, powerful cutter systems, and ease of transport and operation.
General & Dimensions
- Model: MD-615 Horizontal Dredge
- Weight: ~23,000 lbs (≈ 10,431 kg)
- Length (Overall): 37 ft 6 in (≈ 11.43 m)
- Height: 8 ft 6 in (≈ 2.59 m)
- Width: Transport: 9 ft (≈ 2.74 m) / Working: 9 ft 11 in (≈ 3.02 m)
- Draft: ~22 in (≈ 559 mm)
- Fuel Capacity: ~244 U.S. gallons (≈ 923 L)
- Max Dredging Depth: ~15 ft (≈ 4.57 m)
The vessel’s frame and foam-filled steel pontoons provide stable flotation with integral bulkheads and stiffeners for strength and rigidity during dredging operations.
Propulsion & Cutter Assembly
- Propulsion Type: Hydraulic treble sheave winch system
- Traverse Speed: Variable 0 – 50 ft/min (≈ 0 – 15.24 m/min)
- Cutting Speed: Variable 0 – 15 ft/min (≈ 0 – 4.57 m/min)
- Cutter Head:
- Horizontal full-width, flow-through suction cutter (with optional paddle & cutting teeth
- Variable cutter speed: 0 – 80 RPM (forward & reverse)
- Torque: ~30,828 in-lbs (≈ 3,483 N-m)
This horizontal cutter arrangement allows the MD-615 to efficiently loosen and mix material with the surrounding water before suction, improving the dredge’s delivery to the pump. VMI Dredges
Engine & Pump
- Pump Type: Hi-Chrome cast iron, centrifugal with full recessed impeller
- Impeller Diameter: ~22 in (≈ 559 mm)
- Suction / Discharge: 6 in (≈ 152 mm)
- Hydraulic System: Multiple hydrostatic and valve-controlled circuits with ~100 gallon reservoir and protected filtration loops
The dredge’s pump and cutter are matched for robust removal of soft to moderately firm sediments, with throughput optimized for midsize projects.
Hydraulics & Controls
The MD-615 uses a hydrostatic variable displacement hydraulic system with multiple independent circuits, giving smooth control over cutter and propulsion functions. Total reservoir capacity is about 100 gallons (≈ 378 L).
