LifeTrac Tractor

Overview

Wanted: Patience, as we work through redesigning the navigation over the next few days. Thanks - MA 2012-01-25

LifeTrac is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies. Prototype III stage has been completed, and field testing determined the need for Prototype IV prior to product release.

Featuring a modular design and detachable PowerCube units, it has the ability to rapidly switch between a variety of GVCS machines via the QA Plate. The machine is overbuilt with a focus on lifetime design and ease of repair.

Four hydraulic motors provide skid steer power to the wheels, and a chain tread system enables navigation of extreme terrain.

Status

2012-01-27: Currently the Lifetrac III is undergoing documentation. LifeTrac IV is in development as a retrofit of LifeTrac III but with improvements to bent loader arms, quick attach wheels and a new Bobcat standard QA Plate.

The LifeCat 1.0 was started as a new design that will strictly be a skid steer and not try to combine skid steer and tractor capabilities.

OSE Europe will likely be developing a traditional tractor with standard two-wheel drive based on tried and proven designs in history.

Safety Concerns

No structural engineering analysis has been performed on the LifeTrac. If you choose to replicate this product you are doing so at your own risk and with this understanding. We will be performing analysis soon and will post those results as we get them.

There is also an email to OSE Europe mailing list describing some concerns about LifeTrac safety of use, and points out possible issues with: Frame, Steering, Brakes and Roll-Over Protection.
