New 46,000-Pound Capacity VANTRAAX® Trailer
Suspension System Adds Strength, Trims Weight |
CANTON, Ohio – Hendrickson expands its popular VANTRAAX® air-ride trailer
suspension system family with a superb model for haulers running heavy-duty,
over-the-road box and refrigerated vans.
Introducing a tapered-beam 46,000-pound capacity configuration (HKANT 46K) ideal
for the Canadian market, Hendrickson increases frame strength while trimming 125
pounds from the wide-beam 46,000-pound capacity system (HKAT 46K).
The new VANTRAAX model exemplifies Hendrickson’s Advanced Axle / Beam Technology
(AXT™), which teams tapered-beam and large-diameter axle (LDA™) technologies.
Plans call for AXT to be introduced throughout the INTRAAX® and VANTRAAX
families of integrated trailer suspension systems.
LDA increases the diameter of today’s traditional five-inch axle by about
three-quarters of an inch, which reduces weight while improving component and
system strength.
It delivers a 15 percent increase in bending and torsional stiffness compared to
the five-inch axle tube, while reducing tube deflection under loads to keep the
axle straighter to help enhance fuel efficiency and tire wear.
Hendrickson’s cutting-edge production capabilities, such as friction-welded
spindles and induction hardening, produce the straightest and most consistent
trailer axle-spindle assemblies in the industry.
The new HKANT 46K comes standard with high-strength, low-alloy main rails and K
braces for added durability and strength. The configuration provides a 20
percent stronger main rail and 16 percent more buckling resistance compared to
the current 46,000-pound capacity system (HKAT 46K).
In addition, the robust main rails increase resistance to single-wheel impacts.
For identification of HKANT 46K, the number “80” and a part number are “hard
stamped” into the main rails and K braces.
Modification to the shock attachment doubles its strength, while the model
retains the same shocks and air springs as the current HKAT 46K. With the narrow
pivot tapered-beam, the new configuration uses the high-performance
TRI-FUNCTIONAL® III bushing to deliver the same smooth ride.
Road proven over millions of miles, patented TRI-FUNCTIONAL® III bushings
feature phosphate coated inner metal for corrosion protection and a unique
rubber compound for outstanding durability and ride.
Concurrently, in an enhancement pertaining to all Hendrickson sliding suspension
systems, HKANT 46K models feature a redesigned D-shaped locking pin and
accompanying D-shaped holes in the main rail.
HKAT 46K offers the outstanding and unique features common to all VANTRAAX
systems, along with the availability of a wide array of options including QUIK-DRAW®,
fully-pneumatic pin-pull mechanism; TIREMAAX®, automatic tire inflation system,
and a complete selection of long-life wheel-end and brake choices.
