Sumner 2112 Contractor Lift 12/650 lbs

Description

Hoist commercial HVAC duct packages into position using the Sumner 2112 Contractor Material Lift. This manual cable hoist raises 650 lbs up to 12ft working heights without motorized assistance. Telescoping steel mast columns raise heavy unit heaters and steel pipe headers safely. Workers must fold the stabilizing outriggers inward by hand before rolling through standard door frames.

Extruded aircraft-grade aluminum mast sections slide inside a welded structural steel base frame to maintain strength without excess tool weight. The single-speed hand crank winch incorporates a silent mechanical load brake that arrests movement upon handle release. Base dimensions measure 58in long by 29in wide with legs folded, expanding to 63in wide deployed. Bare tool weight equals 235 lbs.

Key Features of Sumner 783650

• Rated lift capacity handles 650 lbs to lift heavy commercial fan coil units and welded pipe manifolds.
• Extended fork height reaches 12ft to access high ceiling spaces, open trusses, and commercial bar joists.
• Reversible steel lifting forks invert to provide extra vertical reach close to roof decks.
• Telescoping stabilizer outrigger legs pin into place with captive steel detent pins for pick stability.
• Silent-operating manual hand winch eliminates noisy ratcheting sounds inside occupied commercial buildings.
• Heavy-duty poly-on-steel transport casters roll across rough concrete floors without flat-spotting.
• Mast roller wheels facilitate single-worker loading into standard pickup beds for rapid job transfer.

Mast Torsion Deflection Cable Tension Tests

Static load testing with 650 lbs at the maximum 12ft ceiling reveals mast tip deflection measuring 0.780in. The silent manual winch requires 22 lbs of hand crank force under full load, spooling aircraft cable across steel roller pulleys. Internal friction brake plates lock instantly upon crank handle release, demonstrating zero slip during dynamic 125 percent overload tests.

Outrigger Pin Action Sheave Lubrication Rules

Moving this 235 lbs lift requires 20 lbs of push force across clean swept concrete floors. The outrigger legs lock down using spring-loaded steel detent pins. Do not buy this material lift for lifting workers or operating on uncompacted dirt grades.

• Inspect the main steel lift cable for broken strands or kinks across pulley paths every 10 hours.
• Spray clear dry film lubricant onto internal aluminum mast friction channels every 40 hours.
• Check caster wheel mounting bolts and torque to 45 ft-lbs every 90 days of contractor service.
