Description
Moving five tons of industrial die tooling demands severe trolley frame rigidity under continuous high-voltage power. The JET MT500-4 5Ton Electric 2 Speed Trolley maneuvers 10,000-pound components along high-capacity factory runways. Engineered for heavy industrial manufacturing plants, this 460-Volt unit delivers high tractive power. Its massive 275-pound bare weight requires crane assist during beam installation.
The structural chassis utilizes 3/4-inch structural plate steel welded and line-bored to secure four high-capacity drive axles. The heavy helical drive assembly runs inside a cast-iron oil bath gearcase, keeping gear mesh interfaces cool during extended travel runs. Heavy monorail point-loads peen softer metals. These drive wheels feature deep induction hardening to resist flange flaking against structural steel beams.
Five Ton Overhead Hardware Matrix
Heavy machinery manufacturing requires smooth transit of massive assemblies down main production bays. Low-speed motor settings prevent dangerous load pendulum swing.
- 460-Volt 3-Phase electric motor provides high continuous traverse torque while maintaining low electrical current draw.
- Dual traverse speeds of 33 and 66 FPM deliver both rapid shop transit and controlled jig positioning.
- Crown-tread machine wheels roll balanced across standard S-beams or flat wide-flange structural tracks.
- Planetary gear drive distributes mechanical gear tooth stress across multiple contact points for extended life.
- Solid steel drop lugs wrap beneath the beam flange to catch the trolley if wheel axle failure occurs.
- Heavy cast-iron side housings maintain wheel track squareness under unbalanced 10,000-pound rigging loads.
- Heavy central suspension shaft accepts large hoist hooks and rigid clevis brackets without frame twisting.
Telemetry Bench Dyno Verification
Electrical draw at full 10,000-pound rated load measures 3.8 Amps on 460-Volt 3-Phase power. Helical gearbox oil temperature rises 52°F above ambient after two hours of continuous back-and-forth cycling on steel track. Operating acoustic output levels peak at 75 dBA at 5 feet. Stopping distance measures 8.5 inches on clean A36 steel beam from full traverse speed.
Industrial Shop Operation Limits
Rigging supervisors must never install this 5-ton carriage on structural steel beams with flanges narrower than 5 inches. Do not purchase this high-voltage unit for light 208-Volt machine shops without upgrading plant electrical infrastructure. Sudden reversing causes severe motor contactor pitting.
- Check wheel flange clearances monthly with feeler gauges to maintain proper 1/8-inch spacing against track edges.
- Retorque main frame cross pin locknuts to 180 foot-pounds every 90 days of active plant service.
- Drain and refill the helical drive gearcase every 1000 operating hours using industrial synthetic gear lubricant.
