Description
Straighten twisted commercial mower cutter decks and pull heavy machinery onto transport trailers without equipment failure. The Atlas Lifting and Rigging ALH 3.2 Ton lever hoist delivers 6400 lbs of tension force across a 15-foot chain drop. This rigging hoist features an oversized shipyard hook. The open hook throat slips over wide frame channels that block standard safety hooks.
Grade 100 alloy steel load chain provides exceptional tensile strength while resisting abrasive grit from dirty shop floors. A heavy cast ductile iron gear case shields internal needle bearings from impact damage. The short steel operating handle works inside confined machine compartments with minimal swing clearance. Double pawl Weston mechanical brakes hold tension without fluid drop, while an internal slip clutch prevents mechanical failure during severe over-pull events.
Key Features of Atlas ALH-032-15-OP-SH
Master mechanics use this long-reach lever hoist to extract stuck utility machinery and straighten bent trailer tongue assemblies. The open shipyard hook latches onto heavy machinery crossmembers without extra hardware.
- 3.2-ton 6400 lb load capacity straightens warped commercial equipment frames and decks
- 15-foot Grade 100 alloy chain delivers reach for deep ditch machinery extractions
- Oversized shipyard hook throat seats around heavy structural channel flanges without shackles
- Mechanical overload protection slips internal clutches when tension exceeds safe boundaries
- Weston double pawl brake locks suspended machinery in position without creep
- Ductile cast iron casing protects the reduction gear train against jobsite impacts
- Hand-operated free-spool knob allows rapid chain adjustment prior to load engagement
Tensile Pull Bench Telemetry Data
Pull test stands confirm holding integrity at 9600 lbs with zero brake slip. Manual handle effort requires 68 lbs of downforce under full rated 6400 lb tension tests. Acoustic readings peak at 72 dBA during continuous ratcheting cycles. Shipyard hook deformation starts at 380 percent of working load limits without brittle fractures. The overload slip clutch activates between 110 percent and 125 percent of rated capacity, blocking dangerous lever inputs.
Rigging Safety Setup Negative Filters
Disengage the ratchet pawl to feed chain slack by hand until the shipyard hook seats deep in the saddle. Keep tension straight between hook shanks to prevent housing twist. Never use this open shipyard hook configuration for vertical lifting of loads over open shop work zones.
- Grade 100 alloy chain links require ISO 46 mineral lubricant coats monthly
- Weston brake friction linings must remain dry and clean from chemical overspray
- Shipyard hook throat opening demands digital caliper logging every quarter to detect spread
