Description
Moving 10000-pound steel dies across overhead crane bays by hand risks crushing plant workers. The JET MT500 5 Ton Electric 2-speed trolley traverses heavy structural I-beams under motorized control. Operating on 230/460 Volt 3-phase power, it transports heavy industrial hoists. The wide wheel flange requires adjusting spacer washers to match specific beam widths.
The trolley side plates are flame-cut from heavy 5/8-inch structural carbon steel plate to eliminate spreading under 5-ton suspended loads. Four crown-tread cast-iron wheels feature hardened running surfaces and ride on double-sealed ball bearings to roll with minimal friction along I-beam flanges. A heavy-duty worm gear reduction drive connects to a 3-phase squirrel cage induction motor, providing self-locking braking capability to prevent runaway trolley drift when power is cut.
Motorized Trolley Hardware Matrix Data
Fabrication shop supervisors and foundry riggers require controlled horizontal hoist transport to position massive dies without swing. This 3-phase motorized trolley handles 5-ton loads with positive control.
- 5-ton 10000-pound load capacity transports heavy electric chain hoists across structural overhead beams.
- Dual-speed traverse motor provides 39 FPM fast positioning and 19 FPM precision creep speed.
- 230/460 Volt 3-phase electrical configuration accommodates standard commercial industrial plant power.
- Hardened cast-iron wheels fit both standard I-beams and wide-flange H-beams without binding.
- Integrated anti-drop plates prevent trolley wheels from derailing in the event of wheel axle failure.
- Wrap-around steel bumper guards protect trolley drive wheels from collision damage against end stops.
- Heavy threaded load pin uses precision spacer washers to adjust track width from 5 inches to 8 inches.
Trolley Load Dyno Telemetry Data
High-capacity load cell testing tracks motor current draw and gear heat under maximum suspended tonnage. Traversing a 10000-pound test ingot at 39 FPM on 460 Volt 3-phase power draws 3.2 Amps continuous current. Worm gearbox oil temperatures level off at 148°F after four hours of continuous travel cycles. The automatic holding brake halts trolley movement within 4.5 inches of button release at full speed. Acoustic sound output measures 66 dBA at 5 feet during motorized travel.
Field Service Maintenance Boundaries
Foundry and steel fabrication bays subject overhead cranes to heat, grit, and shock loads. Do not operate this trolley on warped, oily, or unlevel runway beams exceeding a 1 percent slope, as the drive wheels will lose tractive grip. Never bypass the mechanical anti-drop lugs.
- Inspect wheel flange wear and bearing play every 90 operating days.
- Check gear lubricant level in the worm drive gearbox every 6 months.
- Verify torque on trolley spacer pin retaining nuts every 30 operating days.
Commercial Warranty Package Contents
