Description
Shop bays stall when crane operators push six-thousand-pound dies across manual monorail beams. The JET MT300 3 Ton Electric trolley propels heavy shop fixtures across overhead steel without manual push fatigue. Built for industrial machine shops, this unit runs on 230-Volt 3-Phase power. Its fixed two-speed motor cannot feather speeds for micro-inch die sets.
Structural side cheek plates use cast-iron construction to damp motor vibration across overhead beam spans. The hardened helical gear train rotates inside an oil-filled cast case to eliminate friction tooth wear under continuous full-load travel. Flanged carbon-steel wheels feature induction-hardened rims that resist rail gouging. Internal deep-groove ball bearings reject metallic grinding dust that drifts through heavy manufacturing facilities.
Traverse Drive Mechanical Hardware Matrix
Two-speed traversing moves multi-ton dies across shop bays with continuous traction. Operators shift between fast travel and controlled alignment at the pendant.
- 230-Volt 3-Phase motor provides reliable torque without continuous circuit breaker thermal trips.
- Dual travel settings of 39 and 78 FPM balance transit pace with work bench alignment.
- Crowned machine wheels roll across tapered standard S-beams and flat wide-flange tracks.
- Oil-bath gearbox lubrication cools hardened helical gear sets under extended factory production cycles.
- Drop-stop steel safety lugs hold carriage elevation if wheel axle bearings fail.
- Molded rubber bumpers absorb end-stop impact shock to preserve internal drivetrain integrity.
- Threaded central suspension shaft fits beam flange widths from 4 to 8 inches.
Dynamometer Telemetry Thermal Load Testing
Electrical testing under full 6000-pound load draws 4.8 Amps on 230-Volt 3-Phase power. Gearbox oil sump temperatures rise 44°F above ambient room temperatures after two hours of continuous transit cycles. Acoustic sound levels reach 72 dBA measured 4 feet from the drive chassis. Track braking distance measures 5.8 inches on clean structural steel from top speed. The induction motor runs at 1720 RPM under full working capacity without motor slip or rotor speed droop across heavy structural I-beams.
Field Service Rigging Application Boundaries
Never install this traverse carriage on crane runways with curve radii tighter than 43 inches. Do not purchase this carriage for chemical plating shops where acid vapor degrades electrical insulation. Off-center rigging pulls chew through drive wheel flanges and ruin bearing seals.
- Verify side plate clearance measures 1/8-inch wider than track beam flanges during routine inspections.
- Retorque suspension frame tie bolts to 140 foot-pounds every three months of crane operation.
- Flush and refill the drive gearbox with industrial SAE 90 lubricant every 12 operating months.
