Background

The OSE Quick Attach will be used to implement a wide range of attachments for the OSE skid steer. The design considerations were:

1.Use existing OSE parts (4"x4" box tube, 1/2" plate, 1" bolts, etc).

2.Minimize welds main attachment method bolting.

3.Modular so the spacing can be changed according to attachment.

4.Conforms to SAE-J2513 standard.

SAE standard: File:Sae j2513.pdf

See LifeTrac_Bobcat_Standard and Quick_Attach_Plate_Standard for background on geometry and discussion of ASTM specification of the geometry.

Justin Log by Justin Downs takes it from here.

Product

V1

hashed out different design options, made original DXF file.

The drawing shows a reference for multiple designs, the DXF file has the dimensional layout (select layers accordingly, when they are all on it is cluttered).

For the next step it would be good to talk with whomever will fabricate it to lock in the most efficient build based on available parts, especially for the catch mechanism.

Basic layout for quick attach skid steer mech:

V2

Added in more dimensional work for attachment spacing to skid steer, finished latching mechanism.

Latch mech: The latching mechanism KISSes by utilizes a 5/8" threaded rod that attaches to a 1/2" plate with weld nuts. The plate moves the latch rod to connect and disconnect, this gets rid of any spring or lever which could jam or release during use.

All parts are standard McMaster.

Notes

General notes:

V1

Good work, needs specifics of actual skid steer. Needs discussion with Justin.

V2

Ready to build first prototype. Final fit up will be determined after build.

TO DO

To be done:

V1

1.Finalize dimensions on actual skid steer, spacing, fit up etc.. With consideration to the bobcat spacing. 2.Finish catch mechanism based on available parts (some ideas are in the attached drawing).

V2

1.Finalize dimensions on actual skid steer, spacing, fit up etc.. With consideration to the bobcat spacing.

2.Make a Sketch up file?
