Atlas Lifting and Rigging ALH 3.2 Ton Lever Chain Hoist 15 Ft. Chain Ship Hook

Description

Command precision plate alignment and hull positioning inside tight shipyard drydocks without burning weld lugs. The Atlas Lifting and Rigging ALH 3.2-ton lever chain hoist delivers 7050 lbs of pulling force across a 15-foot stroke with a shipyard hook. It locks steel frames fast, though side-loading the hook over sharp beam edges risks hook damage.

Atlas builds the hoist body from high-strength stamped steel, enclosing heat-treated spur gears and a Weston-style mechanical load brake. Grade 80 black oxide alloy load chain feeds through machined guide rollers to a point-loading forged shipyard hook. The short-handle ratcheting lever provides high mechanical leverage inside cramped welding cells. Total unladen tool weight registers at 42 lbs on the shop scale, designed for heavy pulling.

Features of Atlas ALH Hoist

Shipbuilding drydocks, bridge construction sites, and heavy structural steel fabrication shops demand point-loading hook versatility and dependable mechanical braking. Riggers and boilermakers operate this lever hoist inside cramped hull compartments, pipe trenches, and structural column joints.

• 7050-lb rated pulling capacity handles heavy hull plates, structural beams, and machinery skids.
• Specialized point-loading shipyard hook fits into structural torch-cut holes without bending hook tips.
• 15-foot Grade 80 alloy steel load chain delivers high tensile strength and extended reach.
• Weston-style mechanical automatic load brake holds tension secure the instant lever ratcheting stops.
• Short lever handle design provides high mechanical leverage inside cramped welding cells.
• Free-chain neutral knob allows rapid manual slack chain take-up to connection points.
• Enclosed stamped steel gear housing protects internal ratchet teeth from mud, grit, and rain.

Mechanical Bench Proof Load Telemetry

Proof load diagnostics verified mechanical brake holding at 150 percent rated capacity under a certified 10575-lb static load test. 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 78 lbs of handle pull to tension full 3.2-ton capacity. Decibel sensors registered 65 dBA during ratcheting strokes. Shipyard hook throat opening showed zero permanent stretch under destructive proof load testing.

Jobsite Rigging Realities Maintenance Directives

The rubberized lever grip and specialized shipyard hook offer positive rigging command during structural plate fit-up. This heavy lever hoist is not built for hoisting personnel, pulling across 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.
• Weston brake ratchet teeth and pawls require dry brake testing and cleanout every 90 days.
• Internal drive gears and chain guide rollers require fresh extreme pressure grease every 6 months.
