Atlas Lifting and Rigging ALH 9 Ton Lever Chain Hoist 10 Ft. Chain with Overload Protection

Description

Positioning heavy locomotive trucks and bridge girders with mechanical overload protection prevents dropped loads and bent ratchet handles. The Atlas Lifting and Rigging ALH 9-ton lever chain hoist delivers 19841 lbs of ratcheting tension across a 10-foot reach. It secures steel structures fast, though manual lever effort requires two-man pacing on maximum tension pulls.

Atlas constructs the heavy hoist body from structural stamped steel, enclosing heat-treated spur gears and a Weston-style mechanical load brake. An integrated mechanical overload protection device slips if tension exceeds rated capacity. Three falls of Grade 80 black oxide alloy load chain feed through machined guide rollers. Forged alloy steel hooks swivel 360 degrees, bringing total unladen tool weight to 105 lbs on the rigging scale.

Features of Atlas 9-Ton Hoist

Shipbuilding drydocks, bridge construction sites, and heavy structural steel fabrication shops demand extreme ratcheting tonnage and failsafe mechanical braking. Riggers and millwrights deploy this massive lever hoist inside turbine pits, hull compartments, and structural bridge anchor joints.

• 19841-lb rated lifting and pulling capacity handles locomotive frames, heavy bridge girders, and machinery.
• 10-foot Grade 80 alloy steel load chain provides exceptional tensile strength and deep reach.
• Mechanical overload protection slips automatically if pulling forces exceed safe working limits.
• Weston-style mechanical automatic load brake holds full rated capacity the instant ratcheting motion stops.
• Heavy ratcheting hand lever delivers maximum mechanical advantage during extreme structural pulls.
• Free-wheeling chain mechanism allows swift manual chain take-up to hitch tension points fast.
• 360-degree swiveling forged alloy hooks with safety latches prevent rigging sling disengagement.

Mechanical Bench Proof Load Telemetry

Proof load diagnostics verified overload slip clutch activation at 115 percent capacity and brake holding at 150 percent rated capacity under 29760 lbs. Ratchet mechanism friction produced a modest 14°F temperature climb above ambient room temperature after twenty consecutive full-load strokes. Manual lever operating effort required 88 lbs of handle pull to tension full 9-ton capacity. Decibel sensors registered 66 dBA during ratcheting strokes. Forged hook throat opening showed zero measurable stretch under destructive proof load testing.

Jobsite Rigging Realities Maintenance Directives

The heavy ratcheting lever and free-wheeling neutral knob offer positive control during structural plate fit-up. This heavy-tonnage manual lever hoist is not built for hoisting personnel, pulling over sharp unpadded beam edges, or using cheater pipes on the lever handle.

• Grade 80 load chain demands regular caliper checks for link stretch and wear gouges.
• Overload slip clutch mechanisms require proof load torque verification every 12 months.
• Weston brake ratchet teeth and friction discs require dry brake function checks every 90 days.

Commercial Warranty Factory Delivery Manifest
