Steerable Lift-Axle Suspension
SAF-Holland offers the Neway LSZ auxiliary steerable lift-axle suspension system with 13,500-lb capacity. With a 17.5-in. package size, its design is at least 4 in. and up to 10 in. shorter than comparable lift axles, the company says. This compact design is said to offer application versatility while enabling easy installation and service, and it provides extra frame-rail space for component packaging and options.
The Super Chamber lift on the LSZ is claimed to outperform traditional air springs by providing a quick and reliable 4-second lift speed. The design is also said to be more durable than competitive lifts, providing a stronger and more consistent lift force that keeps the axle securely stowed. The Super Chamber position provides increased protection from road hazards and easier access for servicing.
The LSZ’s rolling-lobe air springs are positioned at an angle, which is said to deliver a superior spring rate for increased stability and ride quality. Its parallelogram design maintains precise steering geometry while reducing tire wear.
The “rugged” design uses a kingpin assembly with spherical bearings, which eliminate thrust bearings that often require shimming and reaming. As a result, service requirements are greatly reduced.
