Atlas Lifting and Rigging ALH 6.3 Ton Lever Chain Hoist 10 Ft. Chain with Overload Protection

Description

Tackle heavy equipment frame pulls and massive commercial machinery lifts with built-in gear protection. The Atlas Lifting and Rigging ALH 6.3 Ton lever chain hoist provides 13890 lbs of pulling capacity across a 10-foot reach. This industrial hoist features an internal overload slip clutch. The slip clutch activates during excessive loads to stop gear teeth from stripping.

Dual-strand Grade 100 heat-treated alloy steel load chain provides exceptional tensile strength while resisting abrasive wear. The ductile cast iron housing seals internal bearings against dirt, grit, and wash-bay water. A double pawl Weston mechanical brake locks loads automatically whenever handle pumping stops. Heavy forged alloy steel hooks feature spring-loaded latches, swiveling 360 degrees to relieve chain torque under massive structural pulls.

Key Features of Atlas ALH-063-10-OP

Structural repair shops use this 6.3-ton hoist to pull bent mower frames and lift heavy diesel generator packages. The overload protection clutch prevents equipment damage from operator error.

• 6.3-ton 13890 lb lifting capacity handles extreme commercial machinery rigging tasks
• 10-foot Grade 100 alloy load chain provides reach for deep pulling and lifting setups
• Mechanical overload protection slips internal clutches during dangerous load spikes
• Double pawl Weston style load brake holds heavy suspended equipment with zero slip
• Ductile cast iron casing withstands rough commercial shop environments and heavy drops
• 360-degree swivel alloy steel hooks seat into rigging points without twisting chains
• Compact ratchet handle geometry delivers high leverage inside tight service bays

Overload Clutch Dyno Testing Telemetry

Dynamometer pull benches confirm static load holding at 20835 lbs with zero brake slip. The mechanical overload slip clutch activates reliably between 110 percent and 125 percent of rated capacity, blocking dangerous pulling forces. Manual handle effort measures 84 lbs under full 13890 lb tensile loading. Sound levels remain under 74 dBA during continuous ratcheting cycles. Hook safety latches withstand 1200 lbs of direct lateral force without springing open.

Rigging Safety Directives Equipment Limitations

Shift the directional lever to center neutral to feed chain through the housing by hand before rigging. Verify positive latch closure on both suspension hooks before applying lever pressure. Never use this manual hoist to lift personnel or suspend loads over occupied work areas.

• Dual-strand Grade 100 chain links require ISO 46 mineral lubricant coats monthly
• Ratchet gear teeth require solvent degreasing and fresh EP grease every 250 cycles
• Hook throat gap measurements require digital caliper logging every 90 days
