We recommend that the main monorail or drop zone “SCR hoist” be typically configured as follows:

  • Brand: Electrolift, low headroom model or approved equivalent of electric wire rope hoist
  • Capacity: 5000 lbs. or 6000 lbs.
  • Synthetic gearcase lube
  • Long lift: 80’ to 90’ from grade to the working level
  • True vertical lift: No hook or load drift.
  • A geared upper and lower limit, with a final upper limit switch.
  • Stainless steel rotation resistant wire rope.
  • An overload device, for the protection of equipment and operator.
  • Hoisting speed: 39/13 fpm, slow speed for delicate picking and placing, fast for time saving-long up and down lifts and lowers.
  • Use across the line starters for hoist, trolley, and mainline contactor. Avoid using VFD’s outdoors, unless the control enclosure is climate controlled.
  • 60-minute duty TEFC hoisting motor and continuous duty trolley motor.
  • Weather proofing for outdoor use: NEMA 4 or 4X.
  • If the area is hazardous (I.E. Class 1, Groups C & D, Division II outdoors,) then the control enclosure should be NEMA 7/4X, with intrinsically safe pendant and limit switches.
  • Space heaters in motors and enclosures.
  • Drain/breathers in motors and enclosures.
  • A six-button pendant: Start/stop; up/down; forward/reverse.
  • Epoxy paint, with a topcoat of UV resistant polyurethane.
  • A motor driven trolley with a soft start and a motor brake.
  • A corrosion resistant festooned electrification system.
  • A fused disconnect, at the end of the monorail, within reach of the operator, for emergencies and for lockout.
  • A Shupper-Brickle Hoist Shelter parking area, for the five-year storage.
