Description
Moving two-ton industrial tooling demands absolute bridge control under continuous high-voltage power. The JET MT200-4 2Ton Electric 2 Speed Trolley shifts 4000-pound raw stock across structural rails with steady mechanical authority. Tailored for heavy metalworking cells, this 460-Volt rig powers heavy transit. The substantial 165-pound deadweight complicates single-person installation onto high bay ceiling beams.
Massive 5/8-inch cast-iron side cheek plates bridge heavy axle spindles to support high shear loads. The enclosed motor transfers power through hardened helical gears housed in an oil-filled cast case, reducing frictional transmission losses. Heavy loads crack soft iron flanges. These drive wheels feature deep induction case-hardening to 55 HRC, protecting wheels from galling against structural I-beam lower flanges.
Heavy Rigging Drive Specifications
Production shops require repeatable positioning for heavy jigs without motor overheating. Robust components deliver reliable transit across long monorail track layouts.
- 460-Volt 3-Phase traverse motor delivers reliable continuous power while minimizing plant amperage draw.
- Dual travel speed settings of 39 and 78 FPM allow fast traversing down shop aisles or controlled jig alignment.
- Precision cast wheels run clean on both wide-flange beams and standard sloped S-beam flanges.
- Totally enclosed fan-cooled motor housing prevents metallic grinding dust and moisture from entering motor windings.
- Integrated mechanical drop lugs keep the trolley seated over the beam rail if wheel axle failure occurs.
- Heavy cast-iron side housings maintain wheel track squareness under unbalanced 4000-pound rigging loads.
- Heavy suspension cross shaft accepts standard crane top hooks and heavy hoist clevis mounts.
Thermal Sump Performance Telemetry
Continuous dynamometer pulling at 4000-pound rated capacity registers 1.9 Amps current draw on a 460-Volt supply. The gear case sump warms to 154°F after two hours of cycling, remaining well within synthetic gear oil operating limits. Sound pressure registers 73 dBA at 4 feet. Traverse stop distance requires 6 inches of braking run on clean, dry A572 steel track.
Industrial Shop Operation Limits
Never mount this trolley on structural tracks exceeding 8 inches wide without purchasing an extended beam pin kit. Do not buy this carriage for hazardous offshore washdown environments where salty spray strips electrical junction box gaskets. Rapid direction reversing burns clutch plates.
- Check wheel bearing lateral play annually to detect roller wear before flange contact damages beam edges.
- Retorque side cheek plate tie bolts to 125 foot-pounds every 6 months of active plant service.
- Drain and replace the enclosed drive gearbox oil every 1000 operating hours with ISO VG 220 gear lubricant.
Commercial Warranty Factory Crate Manifest
