Justification

• Owner of an Westendorf tractor loader Bobcat and
  skid steer loader is seeking a way to interchange
  the bucket attachment between tractor loader and
  skid steer loader.
• Save money and increase productivity and
  diversity of machine usage.
• Economic benefit by increasing the capacity of a
  skid steer loader and reducing the number of
  implement attachments purchased.

3
Background

• Objective
• Conceptualize, build, and test an adapter to
  mount a Westendorf tractor loader bucket on a
  skid steer loader.
• Use in snow clearing, silage livestock
  feedstuff handling, manure/livestock bedding, and
  other handling applications of high volume, low
  density, and lightweight materials
• Development of attachment for a specific customer
  who approached our team with this idea

4
Background

• Customer's input and concepts are incorporated
  into project goals and criteria
• Main goal is to utilize this adapter for snow
  clearing
• Secondary uses will be livestock feed, manure,
  and bedding handling
• NOT intended for excavation applications or
  heavy-duty work
• Approach project as a ONE TIME contract with
  customer

5
Background

• Due to time constraints (both class time and need
  for the product ASAP by customer) the main
  objective is to develop a quality product as
  timely as possible
• Therefore, extensive and in-depth design analysis
  will NOT be a component of this project (i.e.
  stress, force, wear, materials analyses, etc.)
• Product will be developed and utilized.
  Improvement suggestions will be considered

6
Progress

• 4 Phase Project
• Phase I Research, conceptualization, project
  goals
• COMPLETE
• Phase II Material collection, construction
• COMPLETE
• Phase III Prototype testing, refinement,
  modification
• CURRENT STAGE
• Phase IV Project evaluation and analysis,
  presentation development

7
Completed Objectives

• Jan. 30-Feb. 5 PHASE 1
• Key Objectives A
• 2/1 Develop and define project statement,
  objectives, justification, goals
• 2/3 Contact Implement dealerships, welding shops
  to determine existence of existing/similar
  products
• Feb. 6-Feb. 12 PHASE 1
• Key Objectives B
• 2/10 Define criteria for product, develop
  concept idea
• Week Inspect, evaluate, measure equipment to
  prepare for machine design
• Week Meet with customer to determine wants/needs
  of the concept product

• Key Objectives C
• 2/17 (target completion date) Model/draft
  concept design with computer modeling program
  (ProE or Solidworks)

8

• Week Gather construction materials
• Feb. 27-Mar. 5 PHASE 2
• Key Objectives E
• 3/1 Begin construction and assembly of prototype
  unit
• 3/1 Track hours building prototype unit
• 3/1 Define prototype test procedures and
  criteria
• 3/3 Evaluate progress, modify project schedule
  as necessary

10
Progress to Date

• Skidloader Capacities/Specifications (Bobcat S185)

11
Progress to Date

• Tipping Load of Bobcat S185 4,076 lbs
• This is the maximum amount of weight skidloader
  loader can handle before tipping over. Based on
  total weight attached to the front of the loader
  without considering loader attachments.
• Westendorf bucket weight 700 lbs
• Adapter weight 150 lbs
• Total weight - Tipping Load 3,226 lbs for
  material transfer
• Volume of (Westendorf 96) bucket 1.5 cubic
  yards
• The maximum density of any material to be handled
  3,226 lbs per 1.5 cubic yards.
• (4076-850) lbs 79.7 lbs
• 40.5
  ft3
• Using unit conversions, this value equals 79.7
  pounds per cubic foot
• Calculations show material of less than 79 pounds
  per cubic foot can be handled by our adapter and
  loader.

12
Progress to Date
Densities of Common Ag Materials

• Calculations suggest that any material with a
  density of less than 79 pounds per cubic foot can
  be handled.
• Snow can be moved with our system. Most other
  common farm materials can be transferred with a
  Bobcat skidsteer loader.
• Moving dirt, either from the ground or already in
  a pile, should NOT be moved with our system.

13
Progress to Date

• Maximum Density Volume Capacity Comparison
• 96 Westendorf vs. 68 Bobcat

MAX 112.5 lbs ft3
MAX 79.7 lbs ft3
Volume 1.5 cu. yards
Volume 0.6 cu. yards
Bobcat 68 Low Profile (LP)
Westendorf 96
The Westendorf bucket arrangement has 2.5X the
capacity of the Bobcat bucket!!
Always consult a density table provided by the
company for questions on what materials
should/should not be handled by materials
handling equipment.

Why this Design?

• Customers input and ideas incorporated into
  concept
• Consultation with fabrication professionals
• Similar to Bobcat bucket specifications (3/8
  thick plate)
• Simplicity is desired
• Low Cost
• Ease of fabrication
• Modeled after standard Bobcat bucket mount
• Strength and durability
• Avoid wide adapter as to maintain stability of
  machine (center of gravity)

20
Whats Left

• Begin
• Phase III Prototype testing, refinement,
  modification, painting and appearance
  enhancement
• Phase IV Project evaluation and analysis,
  presentation development
