Description
Position heavy zero-turn cutter decks and tractor loader subframes for shop servicing. The Atlas Lifting and Rigging ALH delivers 5511 lbs of ratcheting mechanical tension through a 10-foot load chain drop. This manual lever hoist requires physical operator pulling force, limiting rapid repetitive lifting cycles compared to electric workshop winches across high-volume maintenance bays.
Durable aluminum alloy casing protects internal reduction gearing from direct tool impacts and shop dirt. Heat-treated Grade 80 manganese steel chain resists tensile elongation under continuous 2.5-ton load stresses. Drop-forged alloy steel hooks rotate 360 degrees on mechanical bearings, preventing load chain binding during awkward mower chassis extractions. Weston style twin-pawl mechanical brakes lock ratcheting tension instantly, preventing load slip during engine bay teardowns.
Key Features Atlas ALH-025-10
Turf equipment technicians utilize this 2.5-ton lever hoist to align heavy commercial mower frames. The compact manual ratcheting design provides fine positioning control during powertrain split procedures.
- A 5511 lb lifting capacity supports heavy commercial turf mower frame realignments.
- The 10-foot chain reach provides ample stroke for machine pulling across shop floors.
- Grade 80 alloy steel chain provides high tensile strength without link deformation.
- Double-pawl Weston mechanical brake locks tension positively to prevent accidental drop hazards.
- Free-wheeling gear selector allows fast manual chain payout before load tensioning.
- Drop-forged steel hooks feature heavy spring latches for secure equipment anchor engagement.
- Ergonomic rubber handle sleeve gives technician grip during heavy ratcheting strokes.
Pull Dyno Telemetry Metrics
Bench dynamometer tests subject this hoist to 8266 lbs of proof tension, showing zero casing distortion. Handle input resistance measures 64 lbs under full 5511 lb rated working tension, enabling single-technician operation without excessive leverage strain. Dual Weston brake friction surfaces register a 29 °F temperature rise across 15 continuous ratcheting cycles, holding suspended loads without measurable mechanical creep. Load chain links maintain pitch tolerances within 0.2 percent after static overload pull testing in commercial inspection facilities.
Field Operation Rigging Protocols
Operators select neutral gear to pull chain slack by hand before engaging ratchet clicks. Never slide extension pipes over the lever handle to increase pulling leverage. Do not use this lever hoist for overhead vertical lifting above active work personnel.
- Inspect Grade 80 chain links for wear or stretch before shop rigging tasks.
- Lubricate ratchet pawls and spur pinions with clean lithium grease every 6 months.
- Measure hook throat gap dimensions to detect spread deformation during annual safety reviews.
