GUIDE BLOCK DESIGN
Our guiding blocks offer the maximum density that is permissable to the undercarriage design. Meaning that rather than reduce our cost by increasing the distance between the blocks we install as many as possible to ensure the guiding blocks do not cause the track to become unserviceable.
– Our guiding blocks are seamlessly moulded to the inner track carcass. If you regularly use cambered roads or work on side hills, you will only wear our guide blocks down, you will not have guide blocks de-bonding!
– Competitor guide blocks are not seamlessly moulded but instead “glued” to the track carcass. When roading on cambered roads or on hill sides they will de-bond before wearing through as they fail at the weakest point first.
Optimum tread height for grip, clean out and ride comfort
COMPRESSION MOULDING vs AUTOCLAVE CURING 2:
BENEFITS OF COMPRESSION MOULDING: Single piece cure means tread and guiding blocks are moulded in a single step ensuring a very strong and durable bond.
The ability to offer curved tread designs which improve cleanout ability, ride comfort and grip in wet conditions.
Less risk of de-lamination between cable layers. Compression moulding uses extremely high pressures to ensure all layers in the track form a single cured member.
DRAWBACK OF COMPRESSION MOULDING: Expensive to setup, tooling investments higher. Manufacturing process difficult to control, process control must be perfect to maintain cable ply spacing, flatness and to eliminate distortion. More difficult to move to mass production.
BENEFITS OF AUTOCLAVE CURING: The benefit of this method is that it is very flexible in track width, length and pitch for the manufacturer. It also has reduced tooling investments and is easier to move into a mass production system.
The carcass structure features minimal distortion due to a uniform cure.
DRAWBACKS OF AUTOCLAVE CURING: Our competitor’s manufacturing process for the tread bars means they can only fit straight tread bars to the track. This significantly limits the flexibility. Straight extruded tread can cause excessive vibration and poorer clean-out. It is a limiting factor of this production process. Curved moulded tread offers greater cleanout and ride comfort, hence why it is used in every agricultural pneumatic tyre. Vibration, ride quality and cleanout often suffers due to the restrictions in the process.
HYBRID COMPRESSION/AUTOCLAVE MOULDING
Our guiding blocks offer the maximum density that is permissable to the undercarriage design. Meaning that rather than reduce our cost by increasing the distance between the blocks we install as many as possible to ensure the guiding blocks of do not cause the track to become unserviceable.
DURABILITY: Our Endura Re-trax remanufactured tracks are designed to last as long as new tracks. The process we use means we don’t overcure the original carcass or affect the integrity of the ply structure & main cables.
TREAD BAR MOULDING STRENGTH: Our Re-trax use a compression moulded tread bar that is the cured to the original carcass using a special autoclave curing method.
GUIDING BLOCK MOULDING STRENGTH: We regularly see autoclave cured tracks that have more than 50% tread remaining but the guiding blocks have broken away from the main carcass. We can replace these with a compression moulded equivalent which will exceed the life of the existing design.
CABLE/PLY STRUCTURE INTEGRITY: Our Endura Re-trax The cable/ply structure is not affected by our re-manufacturing process and so it is maintained. We do inspect the ply layers thoroughly as part of the acceptance process to ensure long term reliability can be achieved.
