Feasibility Analysis

Tilt N' Store

What type of pulley setup would we need to create in order to improve the Mechanical Advantage on our Tilt N' Store design concept? How can we do this at minimal cost?


Assumptions:

  1. We will use a winch device to pull the ropes on the pulley; therefore, we are looking for a pulley setup that will provide a load force that is <100lbs.
  2. Upper Bound on the weight lifted is 450lbs.
  3. System is set up to pull straight up and down.
  4. Lifted Weight needs to travel 7 feet.
  5. Rope is 5/8 inches thick
  6. All Cost presented represent an upper bound.

2-Level Golf Cart Storage

Can golf carts be stored on a 2-level system?


Assumptions:

  1. Carts can weigh up to 900 lbs including cart, batteries, and operator
  2. Use largest dimensions and treat cart like a rectangular prism for analysis
  3. Clearance height of 6' set to allow for operator to drive cart under platform without hitting their head
  4. Largest allowable ramp angle of 20 degrees up from the horizontal
  5. Apparatus to lift cart would be costly and not reasonable for purchase

Sarah's Section

Can we reduce the physical demand of loading/unloading the truck? How can we do this at minimal cost?
Assumptions:
  1. Needs to be able to lift up to 300 lbs.
  2. Require employees to lift less than 50 lbs.
  3. Setup time should be less than 5 minutes.
  4. Allow for efficient loading/unloading of truck.

Safe Lifting Limits

How safe are the current lifting methods? If they are unsafe, what weight limit should we set?


Assumptions:

  1. The employee will be predominately lifting or lowering, therefore the NIOSH lifting equation will give us accurate results.
  2. The employees are all in good (normal) physical health for their age and gender.
  3. All tasks are single tasks, not multitasks, therefore a single task job analysis worksheet can be used.
