Ingersoll Rand 1-1/2 Inch Air Impact Wrench, 5450 Ft-Lb D-Handle

Description

Massive steel mill roll stands and heavy crane track bolts defeat one-inch impacts, freezing critical plant maintenance schedules. The Ingersoll Rand 1-1/2 Inch Air impact wrench unleashes 5450 ft-lbs of maximum breakaway torque to shatter seized industrial hardware. It dominates severe bolting teardowns, but maneuvering this thirty-five-pound tool requires two-man handling or mechanical support.

The front clutch features a severe-duty twin-hammer mechanism machined from chromium-nickel-molybdenum alloy steel, delivering balanced rotational blows to survive extreme torsional shock. A titanium hammer case shields internal clutch components against severe impact drops. Inside the motor wet-end, heavy phenolic composite rotor vanes glide inside an induction-hardened ductile iron cylinder. Bronze end plates and oversized needle bearings hold precision clearances, resisting severe radial side-loading during stubborn flange breakout.

Hardware Performance Matrix

Heavy industrial plant maintenance and structural bridge construction demand immense rotational breakaway force and rugged metallurgical components. This 1-1/2-inch pneumatic impact wrench spins stubborn equipment bolts and high-torque flange hardware free without hesitation.

• 5450 ft-lbs maximum torque ceiling shatters frozen mill roll bolts and structural bridge hardware
• 1-1/2-inch square drive anvil with through-hole retainer locks giant industrial impact sockets secure
• Twin-hammer impact mechanism balances rotational impacts to reduce stress on internal hammer pins
• Titanium hammer case front housing protects internal clutch components against heavy drop damage
• Ergonomic D-handle with inside trigger provides firm two-handed leverage on horizontal flanges
• Ductile iron motor cylinder withstands line particulate contamination from plant air drops
• 1/2-inch NPT air inlet port delivers massive pneumatic volume to feed the high-displacement motor

Dyno Realities Air Telemetry

Torque dyno testing records dynamic air consumption of 85 CFM at 90 PSI dynamic under full load stall, compared to 22 CFM at free-run. Free speed measures 3250 RPM, delivering 750 heavy blows per minute. Dynamic line pressure loss across 50 feet of 3/4-inch hose measures 9 PSI during continuous stall cycling. Adiabatic expansion chills the handle exhaust to 25 degrees Fahrenheit, requiring dry air lines to prevent internal icing. Acoustic noise output meters at 103 dBA under load.

Field Trade-Offs Application Filter

Immense thirty-five-pound mass demands overhead hoist rigging or two technicians during horizontal bolting passes. General commercial truck shops servicing passenger cars or delivery vans must avoid this super-heavy tool; 5450 ft-lbs of torque will shear light automotive axles in half and warp vehicle hubs without warning.

• Feed eight drops of ISO VG 32 pneumatic oil into the air inlet before each shift.
• Pack heavy synthetic impact grease into the twin-hammer cavity every thirty operating hours.
• Inspect the anvil through-hole retainer pin for metal fatigue before mounting sockets.
