Galfab, Inc. Roll-off Hoist Model Numbering Systems

Galfab, Inc. has a smart numbering system to establish their Roll-off hoist Models

  1. Style – 1st and 2nd letters =
    • **DL – Dead Lift
    • **EH – Extendable Tail Heil (Dead Lift)
    • **EX – Extendable Tail to the ground
    • **HH – Heil Huge Haul (Dead Lift)
    • **IO – Inside-Outside Rail
    • **MM – Mil Mar (Dead Lift)
    • **OR – Outside Rail Tail to the Ground
    • **OX – Outside rail Short Extendable Tail to the Ground
    • **SI – Inside-Outside for (Dempster and Dead Lift Containers)
    • *ORHH – Outside Rail for HH (Dead lift containers) Frame O.D. = 35” and cable has swivel eye.
    • *ORSB – Outside rail – Slide Back (also known as Fast Back)

    ** The letter “N” in front of these (making three letters) denotes 10” sub-less frame

  2. Capacity – 3rd and 4th Number denotes rated capacity of lifting cylinders. (*except ORHH and ORSB)
    • 50 = 50,000#
    • 60 = 60,000#
    • 75 = 75,000#
    • Etc.
  3. The 5th, 6th, and 7th numbers are the cab to center of tandem axle required minimum length
    • 174 = 174” C.A.
    • 194 = 194” C.A.
    • 228 = 228” C.A.
  4. The 8th letter denotes the type of lift cylinders
    • S = Single Stage Double acting
    • T = Telescopic multi stage Double acting
  5. The next three plus numbers are the stroke of the lift cylinders
    • 072 = 72”
    • 118 = 118”
    • 074.5 = 74.5”

Example:

Hydraulic Lift Cylinder Clearance When Installing Roll-Off Hoist

Recently we have learned of a pair of lift cylinders being destroyed because of mounting bracket interference when the Roll-off Hoist was raised.

Precautions must be taken to assure clearances for fenders, tarper mounting brackets, bumpers, etc. before and after they are installed.  The hoist must be raised to its full dumping height either with its hydraulics or an overhead lifting crane to establish the amount of needed clearance.  See drawing below.
