Description
Overhead hoists struggle to shift two-ton loads when paired with unpowered manual carriages. The JET MT200 2 Ton Electric trolley traverses 4000-pound machine components along monorails with push-button control. Tailored for commercial equipment maintenance shops, it draws 230-Volt 3-Phase power. Its fixed dual-speed drive cannot provide micro-variable creeping speeds for delicate mold insertion.
Structural side frames incorporate 1/2-inch thick rolled steel plates that eliminate carriage distortion under high cantilever loads. A high-torque induction motor drives hardened helical gear sets submerged in an oil bath to disperse gear tooth contact heat. Inductive case-hardened wheel treads prevent steel spalling across beam flanges. Sealed precision ball bearings isolate internal raceways from steel grit, preventing bearing lockup during continuous fabrication shop operations.
Traverse Motor Hardware Performance Matrix
Production bays move heavy transmissions between teardown benches and wash tanks. Dual-speed controls balance transit velocity with controlled machinery positioning.
- 230-Volt 3-Phase motor provides dependable torque without tripping thermal overload relays under 4000-pound loads.
- Dual travel speeds of 39 and 78 FPM allow fast bay transit or steady jig alignment.
- Machined universal wheels roll balanced across standard S-beams and wide-flange I-beams.
- Sealed helical gear drive reduces gear tooth chatter and heat build-up under high cycle rates.
- Anti-drop steel safety lugs keep the carriage captured on the rail if axle bearings fail.
- Molded rubber bumpers cushion track end-stop collisions to protect internal mechanical drive components.
- Threaded suspension pin adjusts to beam flange widths from 3 to 8 inches.
Dyno Telemetry High Voltage Testing
Current draw under full 4000-pound working load measures 3.6 Amps on 230-Volt 3-Phase current. Drive gearbox sump temperatures stabilize at 146°F after two hours of continuous reverse cycling in 78°F ambient shop air. Acoustic noise output measures 71 dBA at a distance of 4 feet from the drive motor. Braking distance settles at 4.8 inches on clean structural steel from top travel speed. The motor turns at 1715 RPM without speed fluctuation under maximum capacity on standard S-beams.
Field Service Rigging Application Boundaries
Never install this traverse drive on runway beams with track curve radii tighter than 43 inches. Do not purchase this carriage for outdoor coastal yards where unsealed marine salt spray attacks contactor enclosures. Off-center side pulls deform drive wheel flanges and ruin bearing seals.
- Check frame spacer washer tension every quarter to maintain proper beam clearance tolerances.
- Retorque side plate cross bolts to 125 foot-pounds every 6 months of active plant service.
- Drain and replace helical drive gearbox oil every 1000 operating hours with ISO VG 220 lubricant.
Commercial Warranty Factory Crate Manifest
JET backs this traverse drive with a 2-Year commercial warranty covering electric motors, gearing, and structural frame plates. The wooden shipping crate contains 1 2-ton electric trolley, 1 central suspension pin, 1 spacer washer pack, 4 heavy locknuts, and 1 complete hardware installation manual.
