Description
Overhead material transfer stalls when shop hoists run along crude push trolleys. The JET MT100 1 Ton Electric unit propels 2000-pound loads along overhead tracks without manual chain pulling. Built for fabrication shops and steel warehouses, this unit runs on 3-Phase shop power. Travel speeds remain fixed at preset dual motor ratios without variable-frequency feathering.
Structural side cheek plates measure 1/2-inch thick rolled carbon steel to eliminate frame deflection under rated working limit stress. The hardened worm gear motor interface uses bronze alloy worm gears that damp reverse kinetic drive shock when operators slam stop buttons. Flanged steel wheels feature induction-hardened treads to prevent peening under prolonged contact with structural steel track beams.
Overhead Travel Drive Hardware
Cranes move structural components between welding stations with positive motor traction. Dual-speed controls enable rough transit and millimetric work station positioning.
- Dual-speed 3-Phase motor yields travel rates of 39 and 78 FPM to balance cycle speed with alignment precision.
- Heavy structural steel side plates resist outward flex during asymmetric off-center rigging pickups.
- Crown-tread machine wheels roll balanced across both tapered standard S-beams and flat wide-flange profiles.
- Sealed ball bearings on all four guide wheels keep grit out to maintain low roll resistance under rated 2000-pound loads.
- Integral mechanical drop stops catch the carriage if severe wheel fracture occurs during heavy overhead lifts.
- Heavy-gauge rubber buffer stops mount on both frame faces to deaden kinetic energy at beam stops.
- Threaded central suspension shaft accepts various hoist top hooks or rigid lug-mount suspension brackets.
Dynamometer Load Thermal Verification
Current draw on 230-Volt 3-Phase power measures 2.6 Amps while moving 2000 pounds along flat track at 78 FPM. Sump oil inside the drive case rises 46°F above ambient room temperature after two hours of continuous reverse-cycle testing. Sound output measures 72 dBA from a 5-foot standing distance. Braking distance settles at 4.2 inches on clean structural steel beams without load oscillation.
Rigging Safety Application Limits
Crane technicians must never install this machine on vertical lifting tracks or inclined monorail spurs. Do not buy this unit for single-phase electrical service shops without installing an external rotary phase converter. Off-center side pulls chew through wheel flanges.
- Inspect drive wheel teeth monthly for metal burrs, gear tooth galling, or excessive structural beam rail wear.
- Check central hanger pin locknuts every 40 operating hours to guarantee correct beam flange standoff width.
- Flush gear case grease reservoirs every 500 operating hours using NLGI grade 2 extreme-pressure lubricant.
