Description
Frozen heavy mining equipment track bolts, off-highway haul truck wheel lugs, and structural bridge pins snap standard 3/4-inch impact tools. The Cleco 1In Composite Air impact wrench smashes frozen industrial hardware with 1800 ft-lbs of ultimate breakaway torque. Heavy equipment mechanics gain massive fastener removal force, yet high rotating anvil inertia causes severe operator wrist shock when running long wheel nuts home.
A massive twin-hammer impact clutch forged from high-tensile alloy steel strikes the 1-inch square drive anvil with balanced kinetic force. The ductile iron motor cylinder houses six phenolic composite rotor vanes turning within a case-hardened rotor shaft on heavy needle roller bearings. A rugged composite motor housing dampens drive vibration while shielding technician hands from freezing compressed air. A pin detent socket retainer locks heavy commercial truck sockets firm on the 8-inch extended anvil during high-vibration off-road fleet service.
Field Hardware Performance Matrix
Heavy machinery field service trucks and mining equipment repair bays demand 1-inch impact wrenches built with forged steel drive components. The hardware metrics below demonstrate the internal engineering built into this super-duty pneumatic impact tool.
- 1800 ft-lbs breakaway torque shatters rusted heavy equipment track hardware and haul truck lugs
- 8-inch extended anvil reaches deep into deep-dish commercial truck and tractor dual wheel rims
- Twin-hammer impact mechanism strikes balanced blows to reduce vibration during fastener extraction
- 1-inch square drive anvil uses a pin detent socket retainer to lock heavy impact sockets secure
- Six phenolic composite rotor vanes resist moisture wash-out from unconditioned field air lines
- Ductile iron motor cylinder provides long service life under non-stop shop teardown runs
- Side handle support gives the technician balanced two-hand control during heavy horizontal teardowns
Dyno Bench Load Telemetry
Dyno pull testing logs 5500 RPM free speed that bogs to 3400 RPM under continuous impact friction. The air motor draws 7 CFM at free spin and surges to 32 CFM at 90 PSI dynamic under full stall. Supplying air through fifty feet of 1/2-inch hose produces a 13 PSI dynamic line drop. Adiabatic cooling drops casing temperatures to 26°F during extended wheel teardowns. Acoustic output measures 98 dBA.
Field Service Operational Directives
Connecting this heavy 1-inch impact wrench to restrictive 3/8-inch air lines cuts breakaway torque by over fifty percent. Do not operate this high-torque wrench with thin chrome hand sockets, as severe impacts shatter standard hand tools. Running dry air ruins the motor vanes within hours. Fleet mechanics must enforce these three field service rules.
- Inject eight drops of ISO VG 32 pneumatic lubricant into the inlet fitting before every work shift
- Check oil level inside the front clutch oil bath port each month using heavy gear oil
- Use a dedicated 1/2-inch air hose line equipped with high-flow couplers to avoid air starvation
Commercial Warranty Package Inventory
Cleco covers this heavy impact wrench with a 1-Year limited warranty against structural defects in materials and craftsmanship. The box holds the 1-inch extended anvil composite impact wrench, an auxiliary side assist handle, an oil fill syringe, and an operational service manual.
