Description
Anchor extreme industrial turf machinery and massive commercial loader frames during heavy overhaul operations. The Atlas Lifting and Rigging ACH produces 44400 lbs of vertical lifting capacity across a 10-foot chain drop. This 20-ton manual hoist requires structural bridge cranes or heavy gantry anchors, preventing use on standard light-duty shop frames.
Heavy structural steel plates enclose precision triple-reduction spur gears that multiply hand effort into massive mechanical force. Eight strands of Grade 80 heat-treated manganese alloy chain divide lifting tension across precision load sheaves. Dual Weston brake pawls arrest loads instantly upon hand chain release, eliminating hydraulic creep risks. Drop-forged alloy steel hooks rotate on sealed thrust bearings to prevent chain twist under immense equipment payloads.
Key Features Atlas ACH-200-10
Heavy equipment rebuild facilities deploy this 20-ton manual hoist to lift industrial grounds tractors and loader backbones. The manual chain drive provides millimeter positioning control during engine repowering operations.
- A 44400 lb working load rating handles industrial turf tractors and heavy earthmoving attachments.
- The 10-foot lift stroke accommodates low-headroom structural gantry bay configurations.
- Eight-strand Grade 80 load chain architecture divides extreme tension to prevent premature link fatigue.
- Triple-reduction gear engineering minimizes required technician pull effort during high-tonnage lifts.
- Weston style double pawl brake holds suspended industrial chassis without mechanical slip.
- Drop-forged alloy lower hook block pivots 360 degrees without binding under maximum load.
- Heavy-gauge steel casing shields internal gearsets from airborne shop grinding particulate.
Heavy Dyno Telemetry Data
Calibrated tensile pull benches subject this 20-ton hoist to 66600 lbs of proof test tension, confirming frame safety margins. Hand chain pull resistance registers 98 lbs under full 44400 lb working loads, demanding steady two-handed technician effort. Weston brake friction linings produce a 54 °F thermal rise over ambient temperature across extensive cycling tests, showing zero mechanical slip. Machined spur gear teeth show zero pitting or profile deflection after extended load endurance testing in industrial repair depots.
Rigging Directives Safety Rules
Technicians check all eight chain strands for flips or twists before attaching lifting slings to machine frames. Never leave 20-ton loads hanging from the hoist unattended during shop lunch breaks. Do not side-load the lower hook block outside vertical centerlines when hoisting tractor assemblies.
- Caliper-check all eight chain falls for interlink wear or stretch monthly.
- Grease internal spur gears through lubrication fittings with molybdenum grease every 100 hours.
- Inspect hook throat dimensions using manufacturer gauge marks during bi-annual safety audits.
Commercial Warranty Crate Manifest
Atlas provides a 1-Year commercial warranty covering hoist drive gearing and structural steel components. The heavy wooden pallet crate contains the 20-ton manual chain hoist powerhead, eight-strand Grade 80 chain assembly, hand chain loop, proof test certificate, and technical operation manual.
