Description
Tension recovery winches and secure turf machinery during transport across rough commercial landscape terrain. The Atlas Lifting and Rigging ALH delivers 7050 lbs of ratcheting pull force to bind heavy wide-area mowers onto equipment trailers. This lever hoist features a compact 5-foot chain reach, limiting long-distance lifting and high-clearance overhead crane applications.
High-strength cast aluminum alloy housing surrounds the ratchet gear mechanism, reducing field tool weight while maintaining structural impact resistance. Single-strand Grade 80 heat-treated manganese alloy steel chain resists stretching under severe tie-down tension. Specialized drop-forged steel shipyard hooks feature wide throat openings without safety latches, sliding over thick trailer D-rings and mower tow points. A free-wheeling neutral lever mechanism enables quick manual chain pull to take up slack before ratcheting under load.
Key Features Atlas ALH-032-05-SH
Commercial landscape transport crews rely on this heavy lever hoist to chain down wide-area rotary mowers on lowboy trailers. The rugged shipyard hooks slide onto oversized steel attachment points that standard safety latch hooks cannot clear.
- A 7050 lb pull capacity locks commercial turf tractors firmly to transport trailer decks.
- Wide-throat drop-forged shipyard hooks latch onto heavy transport D-rings without binding.
- High-tensile Grade 80 alloy chain provides dependable tension holding during rough highway hauling.
- Compact 5-foot chain length minimizes excess bundle clutter inside landscape crew toolboxes.
- Ratchet handle lever shortens stroke arc for easy operation inside cramped equipment spaces.
- Free-chaining mechanism enables rapid manual chain payout to hook up loads quickly.
- Enclosed ratchet brake holds tension without slipping under intense road transit vibration.
Lever Dyno Pull Telemetry
Bench pull dynamometers subject this lever hoist to 10575 lbs of static test tension, verifying structural yield limits. Short-stroke lever operation requires 72 lbs of handle effort under maximum 7050 lb rated load, delivering rapid tensioning without handle deflection. Mechanical Weston style load brakes record zero slip under continuous static tension, with operating friction surfaces heating by only 24 °F during cyclic ratcheting. The wide-throat shipyard hook forgings show zero throat opening deformation after sustained 1.5-times working load limit tension tests.
Transport Binding Safety Rules
Operators align the lever hoist in direct line with trailer tie-down anchor rings to avoid bending load chains. Never attach cheater pipes to the ratchet handle to gain additional mechanical leverage during tensioning. Do not use open-throat shipyard hooks for overhead vertical lifting above crew members or public roadways.
- Inspect Grade 80 chain links for gouging and road grit abrasion before trailer transport.
- Clean dirt and debris from the ratcheting pawl mechanism and lubricate with light oil monthly.
- Measure shipyard hook throat dimensions to verify zero spread deformation every 90 days.
Commercial Warranty Delivery Manifest
