UD434 – 3″ LWT Basin Cleaning Dredge

Description

3″ LWT Basin Cleaning Dredge

This is a highly-specialized dredge designed by LWT to remove a hardened organic crust from the bottom of groundwater recharge basins, without removing the bottom deposit itself. This is accomplished by the combination of a specially configured dredging head and rototiller along with a very low-flow pump.

This is an electrically-powered machine that can be operated either on board the dredge or by remote control. Basic specifications are as follows:

Physical:

• Flotation – two 10-ga steel pontoons, 42″ (1.07 m) W x 46″ (1.17 m) D x 40′ (12.2 m) OAL
• Working depth – 20′ (6.1 m)
• Operational draft – 26″ (0.66 m)
• Length overall – 50′-9″ (15.5 m)
• Transport width – 11′-10″ (3.61 m)
• Height – 11′ (3.35 m)
• Weight (approx.) – 35,500 lb (16,100 kg)

Power:

• 230/460 VAC, 3 phase, 60 Hz electrical power
• Rototiller motor drive & traverse winch – 75 hp (56kW)
• Slurry pump drive, boom hoist, and head-tilt cylinder – 60 hp (45 kW)

Slurry Pump:

• Gorman-Rupp Model T3A60-B, self-priming centrifugal pump
• Suction & discharge diameters – 3″ (76 mm)
• Semi-open impeller diameter – 8.75″ (222 mm)
• Sphere size – 2.5″ (63.5 mm) maximum
• Typical head-capacity @ 1750 rpm – 250 gpm @ 70′ TDH

Dredging Head:

• Hood assembly – welded 6061 marine grade aluminum alloy, OAL 9′-6″ (2.9 m)
• Rototiller – 9″ (229 mm) diameter, 8′ (2.44 m) long, with 40 Ditch Witch teeth
• Drive – 45 hp (33.6 kW) hydraulic motor
• Speed – variable, 0-200 rpm

This dredge can be bought “as-is where-is” in southern California, or it can be modified to suit the buyer at additional cost.
