CAT Information

• Caterpillar Inc. is the world's largest
  manufacturer of construction and mining
  equipment, diesel and natural gas engines and
  industrial gas turbines.
• Caterpillar uses cutting-edge technology to
  reduce product development time, improve
  productivity, lower operating costs and ensure
  that Cat products continue to meet changing
  customer needs.

Problem statement

• The skid steer loader is a compact construction
  machine used in many applications including
  landscaping and general building. The door
  functions to protect the operator from weather as
  well as from flying objects.
• The door must be redesigned to
• Enhance visibility and sealing.
• Avoid damage to door from lifting loader arms.
• Improve the aesthetics of the door and give it
  the impression that it is an integral part of the
  machine.

7
Problems With Current Design

• Low visibility due to bulky wiper mechanism and
  door handle
• Poor sealing between door and cab
• Potential damage to door by the lift arms

8
Visibility Improvements

• Moved washer fluid reservoir inside the cab
• Simplified and moved latch mechanism
• Positioned wiper assembly on side
• Improves visibility but still hinders operators
  view on the left side

9
Seal Improvements

• Magnetic seal (similar to a refrigerator) creates
  air tight seal between door and cab
• Magnet ensures good seal even when door is
  slightly bent or offline
• After repeated use, it may fail due to the
  elements

10
Prevent Door Damage

• Opening cab door extends a pin over loader arm to
  prevent arms from being raised
• Simple mechanical solution
• When pin bends, the door will jam open

Summary of Feasible Design
The Feasible Design Proposed

• Improves visibility in particular areas by
  repositioning the wiper mechanism and door handle
• Improve sealing by utilizing magnetic seal
• Prevents damage to door when raising load arms by
  placing a safety pin over loader arm
• Reduction in frame size decreases overall weight
  of the door while making it more aesthetically
  pleasing
