Description
Position heavy commercial mower frames and diesel engine blocks for complete drivetrain rebuilds. The Atlas Lifting and Rigging ALH 2-1/2 Ton lever chain hoist delivers 5511 lbs of manual lifting capacity with a 5-foot chain drop. This heavy mechanical hoist features an internal Weston brake. The short 5-foot lift chain optimizes headroom in low-ceiling commercial turf repair shops.
Heavy-duty Grade 100 alloy steel forms the load chain, resisting stretch and abrasive wear under metalworking loads. A cast ductile iron casing encloses the reduction gears, shielding internal teeth from shop drops and hammer impacts. The alloy steel ratchet handle delivers input torque through case-hardened pinions. Forged steel safety hooks swivel 360 degrees to prevent chain twisting during heavy mechanical pulls.
Key Features of Atlas ALH-025-05
Landscape mechanics choose this 5-foot short-reach hoist for lifting zero-turn mower decks onto workbench fixtures. The short chain prevents excess links from tangling in floor work zones.
- 2.5-ton 5511 lb mechanical load capacity lifts diesel engines and heavy mower decks
- 5-foot Grade 100 alloy chain reduces excess floor clutter in tight service bays
- Weston double pawl brake mechanism locks loads securely without hydraulic creep
- Forged alloy steel swivel hooks rotate 360 degrees to stop chain link twisting
- Ductile cast iron housing protects gear assemblies against heavy shop impact damage
- Short lever arm geometry permits ratcheting inside cramped commercial mower chassis
- Manual free-wheeling control knob enables rapid slack chain adjustment prior to lifting
Lever Pull Dyno Verification Data
Bench tests confirm static load retention at 8260 lbs with zero brake slippage. Handle input force requires 58 lbs of manual pressure to lift the full 5511 lb rated capacity. Acoustic output measures 71 dBA during continuous mechanical lifting. Hook throat yield begins at 380 percent of rated load limits, preventing catastrophic drop events. The internal gear reduction mechanism maintains 94 percent mechanical efficiency under heavy operational rigging demands.
Safe Rigging Practices Negative Operational Bounds
Disengage the ratchet pawl to pull chain slack by hand before hooking into tractor lift points. Maintain straight-line tension between upper and lower hooks to eliminate housing side-load stresses. Never use this lever hoist as a ground tow chain for pulling stuck vehicles.
- Grade 100 load chain requires periodic lubrication with clean mineral-based oil
- Internal mechanical brake components require dry solvent cleaning without oil contamination
- Chain guide rollers need inspection every 100 cycles to detect metal groove wear
