Atlas Lifting and Rigging ACH 15 Ton Chain Hoist 10 Ft. Lift with Overload Protection

Description

Positioning heavy turbine rotors with mechanical overload protection prevents catastrophic gear shear and dropped loads. The Atlas Lifting and Rigging ACH 15-ton manual chain hoist delivers 33000 lbs of certified lifting capacity across a 10-foot vertical reach. It hoists giant machine tools secure, though pulling its dual hand chain loops demands two-man coordination on heavy lifts.

Atlas builds the heavy hoist body from stamped high-tensile steel, enclosing precision heat-treated spur gears and a Weston-style mechanical load brake. An integrated overload slip clutch disengages drive sprockets if tension exceeds safe capacity. Three falls of Grade 80 black oxide alloy load chain feed through cast steel guides. Forged alloy steel hooks swivel 360 degrees, bringing total hoist body weight to 225 lbs on overhead trolleys.

Features of Atlas 15-Ton Hoist

Industrial plant rigging, mining equipment repair, and shipyard drydocks demand extreme manual tonnage, overload slip protection, and positive mechanical braking. Rigging crews and machinery mechanics suspend this manual chain hoist from crane gantries, jib cranes, and bridge beams.

• 33000-lb rated lifting capacity handles heavy turbine rotors, excavator car bodies, and crane beams.
• 10-foot total vertical lift height reaches industrial machinery tables and assembly bays.
• Mechanical overload protection slips automatically if pulling forces exceed safe working limits.
• Grade 80 alloy steel load chain provides superior wear resistance and tensile yield strength.
• Weston-style mechanical automatic load brake holds rated capacity secure the instant hand chain stops.
• Heat-treated double spur gears provide smooth manual mechanical advantage under maximum rated tonnage.
• 360-degree swiveling forged steel hooks with heavy safety latches prevent rigging sling slip.

Mechanical Bench Proof Load Telemetry

Proof testing verified overload clutch slip activation at 115 percent capacity and brake holding at 125 percent proof load under 41250 lbs. Spur gear transmission friction produced a modest 16°F temperature climb above ambient room temperature after ten consecutive lifting cycles. Dual hand chain pull required 88 lbs of force to lift full 15-ton capacity. Decibel sensors registered 69 dBA during continuous chain travel. Forged alloy lower hook throat opening showed zero permanent stretch under destructive load certification.

Jobsite Rigging Realities Maintenance Directives

The dual hand chain loops and responsive mechanical brake give riggers micro-inching control during delicate turbine casing placement. This extreme-tonnage manual chain hoist is not built for horizontal pulling, motorized high-speed lifting, or hoisting personnel.

• Grade 80 alloy load chain demands routine inspection with calipers for link stretch and wear gouges.
• Overload slip clutch mechanisms require proof load torque verification every 12 months.
• Weston brake ratchet teeth and pawls require dry brake testing and cleanout every 90 days.
