Self Steer Axles  
 
Introduction
 
• Improves tyre life, especially for trailers with 3 or more axles, under intensive usage on roads with a lot of cornering.
• Improves productivity due to lesser down time on tyres change.
• Improves fuel consumption with smaller driving resistance.
• Improves trailer manoeuvrability with smaller turning radius for long trailer.
 
 
Typical Axle and Suspension Systems
 
• 3 axle suspension with one self steer axles, up to 39 ton capacity.
• 4 axle suspension with one self steer axles, up to 52 ton capacity.
• 4 axle suspension with two self steer axles, up to 52 ton capacity.
• 5 axle suspension with two self steer axles, up to 65 ton capacity.

Disc Brake Axles  
 
Introduction
 
• Increased braking response.
• Outperforms drum brakes.
• Higher efficiency.
• "No fade" braking.
• Ease of maintenance.
• Reduced parts inventory.
 
Vehicle Safety
 
Braking response and brake application control is significantly better with disc brakes even under the toughest braking conditions. Tests confirm that disc brakes out perform 'S' cam drum brakes in extended downhill driving situations. The smaller brake chamber used consumes less air than standard drum brakes to perform a similar task.
 
Braking Performance
 
With the inherent high efficiency of disc brakes the vehicle stops more easily in a straight line and less distance. The disc brake does not suffer from fade under constant brake pressure whereas the drum brake needs gradually increasing brake pressure to maintain the same brake performance.
 
Maintenance
 
Exchanging air disc brake pads take 1/4 of the time of typical 'S' cam drum brake linings resulting in large time savings. Reduced parts inventory is achieved through the use of the same brake components on all the axles fitted with 19.5" and 22.5" wheels. The expected longer life of the main service items also results in fewer service intervals.

Heavy Duty Axles  
 
Introduction
 
• High load capacity up to 17.5 ton for mining and logging operation.
• 6" Round strong beam with yield strength over 420MPa.
• Solid spindle and induction hardened bearing journal.
• 3.5" thread spindle and bearing lock nut, extra safety with simple bearing setting and adjustment.
• Strong hub design machined from Spherical Granite Cast Iron.
• ISO M24 wheelstuds are 21% stronger than ISO M22 Wheelstud.
• Bigger Dia. 420x220 brake drum provides bigger braking force and longer brake lining life-span.
