Description
Maneuvering heavy structural steel components stalls when cheap plain trolleys rack and jam against beam edges. The Atlas Lifting and Rigging Plain Trolley rolls 11,000-pound loads across shop monorails without electric power drops. Built for structural steel plants and shipyards, it handles extreme jobs. Pushing 5-ton suspended loads by hand requires intense physical effort.
Heavy rolled structural steel cheek plates form a rigid frame that resists spreading under heavy asymmetric rigging picks. Universal crowned cast-steel wheels ride on double-sealed precision ball bearings that lock out abrasive blast grit and metal grinding dust. Soft wheels groove fast on hard beams. These wheels feature deep induction hardening across the tread and flange, maintaining true roll geometry across tapered S-beams or flat wide-flange structural tracks.
Heavy Monorail Plain Traverse Hardware
Rigging crews maneuver heavy weldments through outdoor fabrication yards without electrical infrastructure. Heavy-gauge components maintain balance across wide structural beams.
- 11,000-pound working load limit supports heavy machinery bases, large steel plates, and marine components.
- Universal machined wheels roll clean across standard tapered S-beams and flat wide-flange tracks.
- Double-sealed deep-groove ball bearings eliminate regular greasing in dirty fabrication environments.
- Built-in steel drop lugs wrap below the rail to prevent drops if wheel axle failure occurs.
- Heavy steel side plates resist outward deflection from dynamic swinging loads during transit.
- Central threaded suspension pin adapts carriage width to beam flanges from 4 to 8 inches.
- Steel mechanical bumpers absorb end-stop collision impacts to protect rolling element bearings.
Tension Bench Push Pull Telemetry
Push pull load testing under full 11,000-pound deadweight records an initial breakaway force of 98 pounds on level structural steel track. Steady rolling drag settles at 62 pounds of manual force once carriage momentum begins. Bearing temperatures show zero rise above ambient yard temperatures during continuous transport tests. Frame deflection measures under 0.032 inches at 125 percent proof load. Acoustic noise output measures 64 dBA during rolling without wheel screech across dry structural steel runway tracks.
Rigging Safety Application Work Boundaries
Never operate this unpowered plain trolley on inclined runway beams where runaway loads cause deadly impact hazards. Do not purchase this manual unit for high-speed transfer tasks where manual push fatigue creates severe operator strain. Track debris causes sudden wheel lockup and bearing failure.
- Clear track lower flanges of dirt, ice, and metal debris per week using a wire brush.
- Inspect wheel bearings every 6 months for seal damage or loose wheel hub play.
- Check central hanger shaft locknut torque specifications every quarter to maintain proper beam clearance tolerances.
