LifeTrac Modules

We are listing all the modules here for porting to FreeCAD format.

LifeTrac Construction Set Primitive Modules. These modules are parts that go into a tractor, and can be used to build various other related heavy machines.

Stable version of the Structural Power Cube from 2015 - Power Cube v15.6. See Power Cube Genealogy for all prior versions.
Stock Tubing. Hole size is 1-1/8", and 1/4" and 1/2" wall thickness is used.
Stock Bonding Plate, 2013.
Tracks for the microtractor.
Stock Pivot Plate, 1/2" steel.
Wheel as part of Modular Wheel Unit, 2012.
Frame module from LifeTrac 2, 2010. This is before perforated tubing entered in 2013. See LifeTrac_II_Build#Frame.
Frame Module, LifeTrac 6, 2013. This is an example of a typical frame that can be built from our stock tubing. See LifeTrac 6 for details
Modular trailer built from perforated tubing and a tractor-trailer axle. Next step is to convert this to a hydraulic dump trailer.
LifeTrac 4. Proper loader arm geometry was used. Modular Wheel Units were used. Last iteration prior to perforated tubing and structural power cubes.
Backhoe prototype 1. It was built as a front attachment for LifeTrac 1, and side to side motion was obtained via articulation of the tractor.
Backhoe prototype 2 on LifeTrac 4.
Universal rotor driving tracks, 2015. See Modular Wheel Units.
Tracks used in 2015 microtrac and bulldozer prototypes. See Drive Sprocket for build video.
Drive sprocket for bulldozer, 2015. See Drive Sprocket.
3" idlers for Bulldozer, rated for 8000 lb bulldozer module weight. Used in 2015 proof of concept.
Soil pulverizer being used during 2014 build of Faculty House.
Gasifier, built in 2015.
Bulldozer blade built in 2013. See Leandra_Log#June_12.2C_2013.
Side-to-size and rotary pivot, from bulldozer design, see Leandra_Log#June_24.2C_2013
Rotary pivot. Can be used on a buldozer blade or on other implements. See Rotary Pivot
Side-to-side or angle pivot. Can be used on earth-moving blades and other implements, such as universal drawbar. See Angle Pivot
Backhoe side-to-side pivot, built in 2013, see Cory_Log#Pivot
MicroTrac tracks for mounting on rubber wheels, designed in 2013. See Cory Log
Universal Rotor with 3" shaft, built in 2013. See Cory Log.
Ground-hugging pivot, build on LifeTrac 6. See Cory Log.
Backhoe bucket, built in 2013, from Cory Log.
Backhoe boom and stick, built in 2013, see Cory Log#June_25.2C_2013:_Backhoe.
Bobcat Standard Quick Attach fingers, built in 2013.
