Ridgid K-7500 Drum Machine with Pigtail (Cable not included)

Description

Experience the raw rotational torque of an enclosed steel drum powering through dense roots. The Ridgid K-7500 Commercial Drum Machine spins inner-core cables inside 3-inch to 10-inch sewer mains without external whip. This bare package ships without primary cable stock. You must supply your own 5/8-inch or 3/4-inch cable before tackling heavy municipal lateral blockages.

Welded steel tubing forms the heavy upright cart chassis, incorporating built-in stair climbers to protect truck tailgates. A 4/10-HP induction motor connects to 115V wall power, drawing 7.5 full-load amps to rotate the inner drum at 200 RPM through a twin-belt transmission. The corrosion-resistant aluminum alloy drum housing isolates wet debris. The bare machine weighs 150 lbs empty, scaling past 240 lbs once you spool one hundred feet of 3/4-inch cable into the cage.

Key Features of Ridgid K-7500

Root clearing specialists buy Ridgid K-7500 rigs to clean long lateral lines without splattering blackwater across clean basement floors. The dual-drum assembly retains dirty runoff internally while providing steady rotational power against stubborn obstructions.

• Enclosed 4/10-HP induction motor spins drum assemblies at 200 RPM to grind through stubborn roots.
• Dual-drum design prevents cable flip-over inside the cage to stop internal wire tangles.
• Heavy cast-aluminum drum housing seals waste muck inside the machine to keep jobsites clean.
• Tubular steel cart features narrow clearance dimensions to fit through standard commercial doorways.
• Solid stair climbing tracks support machine weight during basement stair transitions to spare worker backs.
• Factory pigtail lead connector couples directly to 5/8-inch or 3/4-inch main sewer cables.
• Pneumatic foot switch cuts motor power on release to protect technicians from sudden cable binds.

Drum Rotational Torque Bench Testing

Bench tests show drum rotational speed drops from 205 free RPM to 182 RPM when driving a 4-inch double cutter through dense wood plugs. The dual-belt drive slips under extreme stalls, absorbing shock before cable cores twist past elastic yield limits. Sustained stalls push electrical current draw to 14.8 amps for four seconds before the motor overload shuts off power. Internal drum bearings show zero play under heavy 100-foot cable loads, maintaining balanced rotation during high-torque lateral runs.

Shop Floor Handling Field Service

Rear loading wheels allow one technician to lever this frame into a pickup bed without lifting the full 150 lbs. Never put this massive machine onto 2-inch kitchen sink stacks. The sheer weight and high-torque drum drive will crack light ABS fittings and rip drain arms from walls. Guide the cable using thick reinforced leather mitts to detect pipe resistance.

• Pull the drum drain plug after wet runs to empty blackwater before highway transport.
• Check drive belt tension monthly and adjust the motor cradle bolts to stop slippage.
• Coat internal drum walls and pigtail cables with rust inhibitor spray between commercial jobs.
