Lifting System Clamping System
Rotating System
• Steel frame• Bolted HDPE-lined steel clamps• Pulley lifting system
• Welded Steel
• Interchangeable winch
• 4 ft. stroke
•Locking Casters
• Hand wheel to rotate
• Bolts to hold top and bottom clamps together
• 360° Rotation
• Polyethylene contact surfaces
• Not to be included in prototype
• Steel frame
• Locking casters
• Non-slip surfaces
• Sliding center section for bottom access
• Unnecessary to validate concept

Steel Frame Subsystem• Validate Design• Minimize Deflection (Less that 1/2" on uprights)
Lifting Subsystem• Lift and lower BBJ tank 4 feet• Adequate winch ergonomics
Rotation Subsystem• Rotates tank manually 360°• Verify location of tank center of gravity• Overall Safety
• Prototype lifted and rotated tank successfully• Clamping system very reliable• Test for center of gravity showed prototype design was off significantly• Winch requires too many rotations (may cause fatigue in operator)• Hand wheel requires too much force to turn (result of center of gravity problem)• Average deflection in uprights was .5”
CG
• Order parts• Machine components• Assemble final design• Train workers in use and safety• Train operators on safe usage and protocol changes• Implement design into manufacturing process
• Change center of gravity on rotation system• Higher quality winch• Taller uprights• Thicker frame tubing• More ergonomic hand wheels
