Description
Rig heavy commercial mower frames for undercarriage maintenance across busy service bays. The Atlas Lifting and Rigging ACH delivers 4000 lbs of mechanical lifting capacity to raise 60-inch fabricated decks and diesel zero-turn chassis. This manual chain hoist lacks motorized speed, forcing mechanics to spend physical effort on repeated shop lifts.
Rugged steel construction shields internal gearsets from severe impact drops on concrete shop floors. Grade 80 heat-treated manganese alloy steel chains resist elongation under sustained 2-ton hanging tensions. Precision spur gears transfer hand effort into raw vertical mechanical pull, while drop-forged alloy steel hooks rotate 360 degrees to prevent chain binding during equipment riggings. The integrated slip clutch stops lifts during severe mechanical overload, protecting technicians from sudden load drop hazards.
Key Features Atlas ACH-020-15-OP
Fleet technicians suspend heavy commercial turf mowers to swap worn spindle assemblies and hydrostatic belts. This manual hoist secures suspended chassis loads across extended fleet overhaul shifts.
- A 4000 lb working load limit handles commercial zero-turn chassis elevation without stress.
- The 15-foot chain drop provides vertical reach for tall service bay crane gantries.
- Grade 80 load chain steel resists abrasive wear during dirty landscape shop maintenance.
- Mechanical overload protection slips under excess tension to prevent catastrophic equipment drops.
- Weston style dual pawl braking secures heavy engine assemblies at variable shop elevations.
- Forged steel swivel hooks pivot 360 degrees to eliminate twisted rigging binds.
- Heat-treated spur gears reduce operator pull force during continuous equipment teardowns.
Hoist Dyno Load Telemetry
Static bench dyno testing subjects this unit to 5000 lbs of proof test tension, verifying structural frame integrity beyond rated capacity. Hand chain pull resistance registers 68 lbs under full 4000 lb working loads, demanding steady technician leverage. Weston brake friction plates generate a 38 °F thermal rise across continuous cycling lifts, holding suspended loads without slippage. Chain link elongation remains below 0.5 percent under maximum load, while the internal gear drive maintains a moderate 74 dBA sound level in indoor shop bays.
Shop Operation Rigging Protocols
Technicians pull the continuous hand loop to raise heavy mower decks through gear reduction. Never use this manual hoist to lift human personnel or support loads above active walkways. Do not exceed the 4000 lb load rating when pulling stuck commercial turf equipment from transport trailers.
- Inspect Grade 80 load chain links for gouges or elongation before shop rigging operations.
- Clean steel spur gear teeth and coat contact surfaces with lithium grease every 100 operating hours.
- Check Weston mechanical brake pawl engagement clearance during scheduled 6-month safety inspections.
Commercial Warranty Crate Manifest
Atlas backs this hoist with a 1-Year commercial warranty against manufacturing defects. The heavy wood shipping crate contains the 2-ton manual chain hoist powerhead, 15-foot Grade 80 load chain, zinc-plated hand pull chain, drop-forged swivel hooks, proof load test certificate, and operator service manual.
