Husqvarna Construction PG 8 Floor Grinder

Description

Curled slab expansion joints and failed industrial coatings stall high-production flooring contractors on commercial warehouse projects. The Husqvarna PG 8 Concrete Floor Grinder levels rough concrete using dual planetary heads. It strips thick coatings fast but requires dedicated 460-volt three-phase electrical connections. Counter-rotating planetary heads balance operational torque to prevent operator fatigue.

Solid cast iron forms the lower head gearcase while tubular powder-coated steel forms the main folding chassis. A heavy 10-horsepower totally enclosed electric motor runs on 460-volt three-phase power drawing 14 full-load amps. Precision hardened steel gears run inside sealed oil baths. The bare unboxed machine weighs 490 lbs, measuring 53 inches long, 29 inches wide, and 46 inches tall.

Key Features of Husqvarna Construction 970605501

Industrial flooring crews buy Husqvarna 970605501 grinders to profile warehouse slabs for high-build epoxy installations. Commercial three-phase planetary grinder pricing delivers maximum square-foot removal production per hour across heavy industrial renovation contracts.

• Ten-horsepower three-phase electric motor provides unstoppable rotational torque on hard aggregate.
• Twenty-eight inch grinding path prepares thousands of square feet of concrete floor per work shift.
• Counter-rotating planetary heads balance rotational torque to eliminate tiring sideways machine pull.
• Heavy cast iron chassis delivers 300 lbs of downward head pressure over diamond tooling without extra weights.
• Built-in three-inch vacuum manifold attaches to high-CFM dust extractors for silica dust control.
• Floating head shroud adapts to undulating slab contours to stop airborne concrete dust leaks.
• Integrated water connection valve allows wet grinding operations to eliminate fine silica dust.
• Heavy-duty transport wheels and breakdown frame allow passage through standard jobsite doors.

Planetary Torque Spindle Runout Tests

Dynamometer testing confirms the 10 HP motor maintains 350 disc RPM under 300 lbs of direct downward head pressure. Full-load three-phase current stabilizes at 13.5 amps without motor heat soak during six-hour production grinds. Spindle runout measures under 0.003 inches TIR across both counter-rotating drive heads. The sealed planetary gearcase runs cool with oil temperatures leveling off at 138 degrees.

High Voltage Wiring Precautions

Moving this 490-lb industrial grinder requires two workers and mechanical ramps or lift gates. Do not buy this 460-volt machine if your facility only provides 230-volt single-phase or standard wall current. Improper phase wiring can spin grinding discs backward, damaging planetary gears. Inspect slab joints for protruding expansion metal before grinding.

• Inspect planetary gear oil levels every 200 hours through the top sight glass.
• Grease spindle bearings every 50 hours using high-temperature synthetic grease.
• Blow fine stone dust out of the electrical switch box after each work shift.

Factory Warranty Hardware Manifest

Husqvarna backs this planetary grinder with a 1-Year warranty covering structural frames, gears, and motor defects. The factory crate includes one PG 8 floor grinder, two multi-accessory discs, a dust port adapter, and an instruction manual.
