Modus Operandi:


Farmer arrives in field with the "Bale Chief" in tow, note large 2mtr bales.


Readying the hydraulics for deployment.


The pick-up table is being lowered and the support wheel begins to unfold.


The pick-up table is in the down position and the side gates begin to adjust.


Now the table begins to swivel into the pick-up position.


The pick-up table is now in position and ready to receive the bales.
Note dual axis of table movement to achieve the angled to horizontal transition during rotation.


Ready to receive first bale of the day.
Note special composition rubber conveyor belts supplied by the GPO.


Note side gates can be positioned for varying widths of bale.


These bales are 2mtrs X 1mtr X 80cm in size.


The bale is now totally "captured" by the pick-up table.


Halfway through the table rotation.
Note the tractor and trailer are still moving throughout the entire process.


The bale is now lined up for discharge onto the lifting platform.


The bale starts on it's journey.


The bale is now on the lifting platform and the pick-up table has returned to it's working position.


The collector ram has started to push the bale towards the rear of the lifting table.


The bale is now positioned at the rear of the lifting table
and the collector ram will return to it's rest position.


The next bale is picked up and ready to load.


Two bales are now positioned onto the lifting table by the collector ram.
The pick-up table is ready to receive the next bale.


The lifting table begins to raise the bales into the stacking position.
The next bale is ready for loading once the lifting table has finished it's cycle.


The first row of bales are now stacked onto the trailer bed.


The loading process repeats until the trailer is full.


The bales are supported from behind by two hydraulic motor driven forks.


Continuation of the loading process. Note hydraulic oil reservoir tank.


Part of the hydraulic fork mechanism.


A full load of bales ready to roll. Note PTO driveshaft coupling to hydraulic pump.
The side supports and rear grippers are now clamping the bales in place.


The lifting table has been extended forwards to accommodate two more bales during transport.
Note the hydraulic pump and servo/valve control box.


The trailer is positioned wherever the farmer wants and now the Bale-Chief is ready to start the unloading cycle.


The rear supporting forks drop down on hydraulic cylinders.


The forks  begin to retract into the trailer body by use of hydraulic motors.


Ready to start the stacking process.


The bed is lifted by means of two powerful hydraulic rams, one booster and one controler.


A closer look at the hydraulic lifting rams.


Some of the hydraulic control lines can be seen in this photograph.


The rear bale-grippers doing their job of holding the stack secure during the lift.


The rear bale grippers are now released by hydraulic rams and the stack is now independent.


The trailer can now be driven away from the stack.


Pulling forward to release the bale stack.


Resetting the hydraulic rams and systems.
All operations and cycles are fully automatic and only require a very minimum input from the driver.


The lifting bed is almost down to it's resting position.


All jacks, rams and motors are now cycled back to their starting positions.


Let's go and find some more bales to load!
