   Thomas Wheeler,
    Engineer of Maintenance
    and Reliability for Mosaic
   Mine materials for crop
    nutrition and feed
   world's leading producer
    and marketer of
    concentrated phosphate
    and potash
              The Problem
 Phosphate and other materials moved
  through steel pipes
 Phosphate is abrasive on the inside of the
 Pipes must be rolled periodically to insure
  the pipes wear evenly
 Pipes are often in very close proximity to
  other pipes
The Problem
          Current Solution
 Currently pipes are lifted and rotated
  using cranes
 Cranes require many workers and a long
  period of time
 Mosaic only owns operates three cranes
 Design a mechanism which will one
  mechanic to roll a pipe by himself
 Must be easy to set up
 Mechanism should secure to I-Beam which
  pipe rest on
 Must be universal for various pipe sizes
         Project Specifications
   Minimum lift height: = 2cm
   Maximum lift load: = 5,000 lbs
   Must be able to rotate pipes 90, 180, and
    270 degrees
   Design must work for pipes varying from
   Must be able to use I-beam as a base
         Project Specifications
   Budget of 1,500 dollars
   Weight must be light enough for a
    maximum of two mechanics to set up and
   Design must not be to complicated or
Preexisting Technology
            Door frame pull up
             bar technology
            vertical force of the
             weight is redirected
             into a horizontal force
             in four different
       Preexisting Technology
 Hydraulic Jack
 hydraulics have
  gotten popular due to
  the large amount of
  power they can create
  through flexible hoses
 hydraulics use fluid
  power to do work
                                   Design One
   Two portable platforms consisting of lifting
    devices similar to automated car-jacks are
    placed on I-beams. Platforms are placed at
    the I-beam locations corresponding to the
    ends of the section of piping needed to be
   A motor will is attached to the lever end of a
    clamp that is connected on the cross-section
    of the pipe.
   Motor rotates and applies a perpendicular
    force to the lever which results in the rotation
    of the pipe.
                       Design One
   I-beam connection is a self
    propping device inspired by the
    iron gym pull-up equipment.
   Uses a stopper at the bottom of
    the I-beam to prevent it from
    falling off when a load is
    applied perpendicular to the
                              Design One
   An adjustable clamp with an extended
    lever is applied to the section of piping.
   A motor/crank system is connected to
    the lever end of the clamp and as the
    montor rotates, the pipe rotates.
Design Two
      weight of the lifting
       mechanism and pipe
       is relocated to two
       connection located on
       the top cross beam
       on the opposite side
       from the mechanism
      mechanism is
       designed to be able to
       adjust to different
       width I-beams
              Design Two
 consist of two hydraulic pumps and four
  lift arms
 two supports are channeled within the
 hydraulic pump pushes and or pulls the
  triangular sliders throughout the channels
Design Two
              Design Two
 Rotating mechanism is a rubber wheel
  attached to a crank
 gear system which will have an
  approximate gear ratio of 50:1
 the torque applied to the wheel will be 50
  times greater than the torque put into the
               Design Three

 Manual vise clamp to
  grip I-beam
 Hydraulic hand jack to
  lift beam
 Electric wheels to roll
  the beam
            Design Three

 Manually installed and used in tandem
    -2 or more used on each pipe
 Connects to the underside of the I-beam
Decision Matrix
              Future Plans
 Take design improvements into
 Make detailed design of chosen concept
 Make trip to Mosaic Co. in central Florida
