This unit was designed for doing on-the-spot inspection of heavy truck brakes, steering, suspension and axle weights.  Along with the basics like braking force, it could check for alignment issues as well as wear and slop in the suspension components.  Unfortunately, the company went out of business and we don't have any of the accessories that plug into it so it is not likely a good candidate for what is was originally intended.  However, it is a wonderful portable hydraulic power platform with lots of components including load-cells that I am sure someone can figure out a good application for.

1) Raise the wheels off the ground with the 3-point hydraulic cylinders.  Unlatch the axle to frame latches.



2) Rotate the wheels out of the way.  In the image above, they are part way.  In the image below the wheels are fully rotated out of the way.



3) Lower the frame to the ground as shown below.  This originally had ramps for driving the truck on but they had disappeared by the time we got this.



4) Reverse the process when you are ready to move to another location.


  

The heart of the system is the 3-cylinder Kubota engine driving the hydraulic pump(s).  The engines radiator is in the foreground of the image below.  Again, things have gotten pretty dirty but there has been very little use.

  

Each of the tread rollers has a hydraulic motor on it.  Each pair of these rollers has a linkage and a straingauge sensor.

 

Note that the engine was runing when all these pictures were taken.  See the reading on the tachometer. and the green light.
  

The fuel tank is red in the image above with the filler tube rising to the left. Behind that is one of the wheel rotation hydraulic motors and torque amplifying gearboxes.  Note all the solenoid valves in the center of the image.  One of the rotational torque load sensors can be seen in the lower right.

     
The yellow plate in the middle of the image above is the top of a 5 ton hydraulic scissors jack.

 

The rear control panel is shown here.  again, we don't have anything that plugs into any of the connectors.  A more direct view of one of the torque linkage strain gauge sensors is shown in the next image.  Note that there are more solenoid valves at the rear.

 

In the upper right of the image  above and in the left of the image below you can see a pair of the hydraulic motors that couple to the tire rollers.

 

The image above shows one of the trailer wheel axle rotation hydraulic motors and torque hub.  The labels are imaged below.

 

The image below is on one of the hydraulic motors attached to the tire rollers.



The section of the trailer where the truck drives in is about 6 feet wide and 112 inches across.



The image below shows the cover for the engine section.  As noted, it could use some sheet metal work before getting attached back in place.
