Atlas Lifting and Rigging ALH 2-1/2 Ton Lever Chain Hoist 15 Ft. Chain with Overload Protection

Description

A 5500-lb mechanical pulling capacity and internal overload slip clutch align warped steel weldments without risk of ratchet failure. The Atlas Lifting and Rigging ALH 2-1/2 ton lever chain hoist delivers positive mechanical tension across a 15-foot reach. It pulls heavy machinery skids secure, though side-loading the hook over sharp beam edges risks hook deformation.

Atlas constructs the hoist body from high-strength 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. Grade 80 alloy load chain feeds through machined guide rollers. Forged steel upper and lower hooks swivel 360 degrees with spring safety latches, establishing 34 lbs total unladen tool weight.

Features of Atlas ALH Hoist

Heavy construction rigging, machinery alignment, and structural steel pulling demand portable ratcheting power and dependable mechanical braking. Equipment mechanics and millwrights deploy this lever hoist inside tight engine compartments, crane gantries, and pipe trenches.

• 5500-lb rated lifting and pulling capacity handles heavy tractor frames, structural steel, and machinery.
• 15-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.
• Short ratcheting hand lever enables full load pulls inside cramped mechanical enclosures.
• Free-wheeling chain mechanism allows swift manual chain take-up to hitch tension points fast.
• Weston-style mechanical automatic load brake holds tension secure the instant lever ratcheting stops.
• 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 8250 lbs. Ratchet mechanism friction produced a modest 12°F temperature climb above ambient room temperature after twenty consecutive full-load strokes. Manual lever operating effort required 72 lbs of handle pull to tension full 2.5-ton capacity. Decibel sensors registered 65 dBA during ratcheting strokes. Forged hook throat opening showed zero permanent stretch under destructive proof load testing.

Jobsite Rigging Realities Maintenance Directives

The rubberized hand grip and free-wheeling neutral knob offer intuitive rigging setup in cramped mechanical bays. This manual lever hoist is not built for hoisting personnel, pulling over sharp unpadded beam edges, or operating with 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.
