SAF-HOLLAND TRAILER AXLES AND SUSPENSION SYSTEMS - AIR SUSPENSION - SAF INTRADRUM
SAF-HOLLAND TRAILER AXLES AND SUSPENSION SYSTEMS
SAF INTRADRUM
The tried-and-tested SAF INTRA with drum brake and INTRADRUM technology is a winner in virtually any transport situation, with special functional reliability and unprecedented economic efficiency.
Perfectly thought-out: The SAF INTRA drum brake combines proven components into a successful system.
Efficient, profitable and virtually maintenance-free – the SAF INTRADRUM is a winner with its powerful and precisely matched components and guarantees planning reliability right from the first kilometre.
For a complete overview of all available components and possible combinations of suspension types, axle versions, ride heights and weights etc. please see the Design manual.
Positioned for Protection
The specially coordinated shock absorber with specific characteristics is positioned in the center of the hanger bracket and with-in the functional suspension arm, thus protecting it from stone chipping and other road debris.
Driving Stability and Safety
Our specially designed 3D bushing element is integrated into the functional suspension arm and provides an optimum of ride performance.
Maintenance Free for Life
Our design incorporates the functional suspension arms and axle beam into one unitized and maintenance free component. This indestructible design provides additional benefits such as: no extra mounting parts, such as axle seats and U-bolts, no re-torquing of screws and nuts.
Light-Weight
The very narrow hanger bracket is symmetrically designed. This saves weight and allows easy installation.
SAFE-GUARD-DESIGN
The patented SAFE-GUARD-DESIGN of the functional suspension arm reliably protects the brake chambers from damage.
Excellent Corrosion Protection
We use great care in long-term corrosion protection on particularly exposed parts, such as hubs, hub caps or screw connections as well as wheel bolts and nuts.
Optimized with Factory Standards
Standard features include: uniform bearings, ABV-preparation, integrated rim system, specific weight reduction, cathodic dip coating process of axle and wheel hub.
Precise cam roller guide
The precision-machined S-cams precisely control the movement of the brake shoes and the contact pressure, so optimal braking action is ensured.
Spherical bearing
The brake shoes on the SAF INTRADRUM are mounted around a spherical head. Thanks to their special geometry, the shoes can move in all directions. This will cause the force to be more evenly distributed across the linings, and a longer service life is guaranteed.
New brake lining
with exceptional brake fade stability, over the entire life of the lining. The lining has exceptional corrosion characteristics, reduces noise generation and guarantees a long and eco-friendly service life.
Replacing brake shoes in seconds
The change is quickly done with a screwdriver and only a few simple manual Actions.
SAF brake shoes
are asymmetrically shaped by computer modelling and are subject to strict production control on an ongoing basis. The optimised brake shoe geometry guarantees improved distribution of force between brake pad and brake shoe, improving brake performance.
Fewer Parts
The SAF INTRADRUM saves space in storage, and considerably reduces the effort involved in maintenance and repair.
The use of steel-brass S-cam bushings
allows for more accurate manufacturing tolerances compared to synthetic bearings, so that they can be installed with almost no play, less vibration and a better brake performance. Noise generationis also significantly reduced.
Improved Corrosion Protection
by galvanising and powder coating, the cover plate is even better protected. In order to increase the corrosion protection of the INTRADRUM even more, the coating thickness on the wheel hub has also been doubled.
SAF ABS Sensing
· exciter ring and sensor holder (as standard/pre-assembled)
· can be activated using simple and reliable plug Connections
SAF Two-side axle lift
For 22.5' wheels
· only weighs approx. 21 kg per axle
· very simple retrofit
SAF One-side axle lift
Specifically for low ride heights
· only weighs approx. 30 kg
· very simple retrofit
SAF Hubometer
With this hubometer the operating times of trailers can be documented precisely and reliably.
· measures the exact mileage of Trailers
· simple retrofit
· quick and reliable mounting
SAF TIRE PILOT
Tyre inflation system for trailers and semi-trailers.
Monitoring and preservation of the set tire pressure in the Trailer.
SAF Brake Chambers
The same strict quality guidelines apply to our brake chambers as for all SAF components. We are using high quality internal components for our brake chambers so that you can depend on the long and secure function of this component. The robust and completely surface coated housing provides additional safety. For an additional advantage the air connections are fully integrated on the SAF brake chambers.
SAF UP train loading system
One of the lightest Train loading Suspension on the market
For secure rail loading with container lifts or cranes.
Currently, 86% of freight in the EU is transported over roads. Traffic is getting heavier, delays are becoming more frequent, and there is an increasing danger of congested roads, with wheels more often moving only slowly towards their destinations. With the new SAF UP train loading system, unproductive time spent on the road is kept to a minimum. We put your trailer safely onto rail, saving you time and money.
Even when you have to load your trailer onto rail unexpectedly, you’ll be optimally equipped with the newly-designed air spring and bellows. It offers maximum support in loading your trailer safely onto rail. Whether you’re on the road or on the train – you’re on the safe side with the new SAF UP train loading system.
Advantages at a Glance
· One of the lightest train loading bellows on the market
· Less wear and a longer life cycle through smooth joining of bellows and support brackets
· No additional equipment (safety ropes, etc.) needed to protect the bellows during loading
· A considerable weight saving of 30 kg when compared to the
previous SAF-HOLLAND design
