Final Design of the Plate

Figure eight shows the final design of the metal plate according to the analysis done by the team.

Lifting Design

Figure nine shows the height constraints for the hoist design. Given the height of the room, the thickness of the metal plate, and the dimensions of the crane, the hoist design was required to stay within 16.44" to provide the required clearance. This is shown in Figure nine below.

 

Figure 9

In the conducted state of the art research a motor hoist was found which was able to meet the required lifting clearances. With a lifting capacity of one ton and a requirement of only 14" under the I-Beam to operate within, the motor hoist is more than sufficient to fulfil the need of a lifting system. This hoist is a Lo-Hed Wire Rope Hoist produced by David Round [7]. Figure ten below shows the motor hoist that will be installed. Table one lists the specifications of the hoist.

 
  Hoist Specifications:
1 Four wheel motor trolley
2 Lifting Speed 20 ft/min.
3 Maximum lift 20 ft.
4 Floor operated pendant push button control
5 Voltages 230/460 re-connectable 3 phase, 60 Hertz

Cost Analysis

Implementation Steps

    1. Drill holes in the concrete
    2. Machine the metal plate
    3. Clean the holes in the concrete
    4. Place the plate in line with the holes
    5. Install epoxy anchor bolt system
    6. Give 48 hours for the drying process of the epoxy gel
    7. Place and weld the shaft of the crane
    8. Fasten nuts onto anchor bolts
    9. Assemble the boom at the top of the crane shaft
    10. Install hoist
