Ridgid K750R Drum Machine

Description

Enclosed drum rotation spins heavy steel cables through grease and tree roots without line whip. The Ridgid K750R Drum Machine clears 3-inch to 6-inch sewer laterals using 200 RPM rotational drive power. You feed cable sections by hand. The heavy loaded drum lacks quick-release pins, requiring two-worker lifting or loading ramps during service truck transit.

Welded tubular steel forms the rugged transport cart, holding the corrosion-resistant aluminum drum on heavy-duty bronze bushings. A 1/2-HP single-phase induction motor plugs into 115V wall power, drawing 7.0 full-load amps to drive the drum at 200 RPM through dual V-belts. An integrated kickstand stabilizes the frame during deep sewer cleanouts. The total machine scales at 119 lbs with 100 feet of cable loaded, measuring 34 inches long by 24 inches wide for doorway clearance.

Key Features of Ridgid K750R

Drain cleaning contractors buy Ridgid K750R machines to clear residential and light commercial lateral lines without slinging wastewater across customer basements. The enclosed aluminum drum traps dirty muck inside while operators guide cable heads through tough root obstructions.

• Dedicated 1/2-HP induction motor generates 200 RPM drum speed to chew through root chokes.
• Corrosion-resistant aluminum drum holds up to 100 feet of 5/8-inch inner core cable.
• Heavy-duty transport cart features solid rubber wheels to roll over rough yard gravel.
• Dual drive belts absorb sudden shock loads when cutting blades hit solid rock obstructions.
• Enclosed drum housing seals wastewater splatter inside to keep customer walls clean.
• Integrated kickstand locks the cart base firm to stop machine walk during heavy rotation.
• Pneumatic foot switch cuts motor power on release for reliable hands-off emergency stops.

Rotational Torque Bench Test Metrics

Bench strain dynamometer tests confirm drum rotation slows from 204 free RPM to 176 RPM when feeding a 4-inch double cutter through dense wood plugs. The dual V-belt drive slips at 24 foot-pounds of torque, protecting cable cores from permanent spiral twist damage. Full locked stall spikes line current to 16.2 amps for three seconds before the internal motor breaker pops. The aluminum drum shaft shows under 0.020 inches of lateral runout, keeping the cart planted on wet basement concrete slabs.

Field Handling Operational Usability Limits

The tall cart handle lets one worker tilt and wheel this 119-lb machine up exterior steps with balanced lever action. Skip this heavy machine on small 2-inch residential sink traps. That thick 5/8-inch cable and high-torque motor will shatter thin plastic traps and tear copper waste arms from walls. Guide the rotating line wearing heavy cowhide pipe mitts.

• Pull the drum drain plug after wet runs to empty blackwater before highway transport.
• Inspect drive belt tension twice yearly and tighten motor bolts to eliminate slippage.
• Coat cable coils with rust inhibitor oil after clearing acidic kitchen waste lines.
