EC TROLLEY SUSPENSIONS

WORKING LOAD LIMIT: 1/4 TO 5 TONS

COFFING ECT, ECGT, and ECMT Models – Plain, geared and motorized trolley suspensions with all the features of basic EC models for added flexibility in a variety of applications.

FEATURES & BENEFITS

  • Plain trolley for manual positioning of hoist and load.
  • Geared trolley for more precise positioning of hoist and load. Standard hand chain drop is 2-feet less than lift.
  • Motorized trolley for faster positioning of hoist and load over longer distances. 35 or 75 FPM speeds standard with optional speeds of 18, 24, 50, 100, and 150 FPM.
  • Voltages: 115/230, 208 – single phase; 230/460, 208, 220/380, 575 three phase. 60 hertz standard, 50 hertz available.
  • Two-speed motorized trolley models optional with 3 to 1 speed ratio, three-phase, single voltage only.
  • Wrap-around side plates act as safety lugs and as bumpers to protect wheels. Available to fit American Standard I-Beams, wideflange, and patented track beams. Specify track type and beam size.
  • Precision trolley wheels machined, cast iron wheels with sealed, lifetime lubricated ball bearings for extended trolley life. Motorized trolley wheels heat treated for added durability. Bronze and stainless steel wheels optional.
  •  Two trolley designs: 4-wheel design on 1/4 – 3 ton negotiates 48” minimum radius curve, including patented track applications. 8-wheel design on 4 and 5 ton reduces beam flange stress.
  • Accessories & options: Full line available to meet a variety of applications.
