Description
Rolling massive ten-ton tooling through heavy machine shops demands robust unpowered trolleys that resist frame spread. The Atlas Lifting and Rigging Plain Trolley supports 22,000-pound loads along overhead beams without electrical hookups. Built for heavy fabrication plants, it carries severe loads. Moving this ten-ton trolley along structural beams requires immense manual push effort.
Frame construction uses 3/4-inch rolled carbon steel cheek plates tied by dual heavy steel cross shafts to prevent frame racking under off-center crane picks. Cast-steel wheels rotate on double-row precision ball bearings sealed to keep out metal slag and foundry dust. Soft wheels groove under heavy loads. These wheels feature induction-hardened rims that resist spalling across standard tapered S-beams or flat wide-flange structural tracks.
Heavy Monorail Plain Traverse Hardware
Heavy fabrication bays transport massive weldments without electrical motor infrastructure. Heavy-gauge components maintain tracking balance across wide structural beams.
- 22,000-pound working load limit handles immense structural weldments, dies, and steel ingots.
- Universal machined wheels roll clean across standard tapered S-beams and flat wide-flange tracks.
- Double-row sealed ball bearings eliminate per day greasing in harsh industrial manufacturing environments.
- Built-in steel drop lugs wrap beneath the rail to catch the carriage if wheel axle failure strikes.
- Heavy structural steel side plates resist outward flex under dynamic swinging crane loads.
- Dual threaded suspension pins adjust carriage width to beam flanges from 4-3/4 to 8 inches.
- Solid steel mechanical bumpers absorb end-stop collisions to protect internal bearing raceways.
Push Force Rolling Resistance Telemetry
Breakaway testing under full 22,000-pound deadweight reveals an initial push force requirement of 190 pounds on level A36 structural steel. Sustained rolling drag drops to 115 pounds of horizontal force once carriage momentum begins on clean beams. Bearing temperatures show zero rise above ambient shop conditions during continuous shop transit. Mechanical clearance holds tight under 125 percent proof load with under 0.038 inches of frame deflection. Acoustic emissions register 64 dBA during manual rolling without metal screech on steel flanges.
Rigging Safety Application Work Boundaries
Never operate this unpowered plain trolley on overhead beams with slopes steeper than 1 degree because runaway loads cause deadly impact hazards. Do not purchase this plain unit for high-repetition assembly tasks where manual push fatigue causes worker strain. Track debris causes sudden wheel lockup and bearing failure.
- Wipe runway beam lower flanges free of grit and metal chips per week using a clean rag.
- Inspect wheel bearings every 6 months for seal extrusion or loose wheel hub play.
- Confirm frame spacer washer torque specifications every quarter to maintain proper beam clearance tolerances.
Commercial Warranty Factory Crate Manifest
