ers, officers, and firefighters, started looking for a
replacement back in 2015. Originally, the committee thought about a Dash CF as its first choice, but
after hearing about and operating the new Quantum with the TAK- 4 front and rear suspension, it
was sold on the new concept. Also, the firefighters
like the roomier Quantum cab.
Just how does the TAK- 4 work? In 2001, Pierce
introduced the TAK- 4 independent front suspension (IFS) system. It is custom built for a Pierce
chassis to give a better road feel, control, and
smoother ride over any kind of surface. It accom-plishes this through a mechanical-over-hydraulic
steering system with two steering gears that provide
power to the steering linkage.
A torsion bar setup, a much beefier version of
what is found on many SUVs, also helps deliver
superior control. Cast steel alloy and ductile iron
upper and lower control arms allow the front
wheels to take on potholes one at a time. And the
lower spring rates made possible by the indepen-
dent front suspension smooth out the road better
than any straight axle rig. It also stops sooner by
shortening stopping distance by 23 percent, has a
45-degree cramp angle, and improves ride qual-
ity by 340 percent (as measured by accelerometer
The system improves handling and enhances
vehicle control. Additional features include 10
inches of suspension travel, a light spring rate,
a robust design and independent wheel movement, low vertical G-forces, a 24,000-pound max
front axle weight rating with 445/65R22.5 tires,
a 22,800-pound max with 425/65R22.5 tires,
larger brake pads and rotors that wear less than the
traditional 15-inch brakes, and an increased load-carrying capacity.
Each of the identical pair of Quantum
aerial ladders is equipped with a 500-hp
Detroit DD13 engine and a Command Zone™
advanced electronics and control system.
The vehicles feature a GVW rating of 74,800
pounds, and the tandem rear axles carry a
GAWR rating of 52,000 pounds. The cab includes seating for four firefighters, a forward-facing EMS compartment, and frontal impact
and side roll protection systems.
The four-section, 105-foot aerial device
includes remote tip controls, a two-way
intercom, a LyfePulley rescue system, and
LED rung lighting. The firefighting system includes a 1,500-gpm single-stage PUC pump,
a 500-gallon water tank, and low mount
TAK- 4® T3™
Tight Turning Technology
TAK- 4 T3 with Tight Turning Technology
combines the advantages of TAK- 4 IRS with
a 100-percent mechanical steering system.
Just like TAK-IFS, the steering system is
a mechanical-over-hydraulic system, free
of electronics, with two steering gears that
provide power to the steering linkage. TAK- 4
T3 is available on apparatus with IRS up to
52,000 pounds tandem axle rating.
Advantages include the following:
• Improved turning radius and diameter.
• Increased tire life with reduced tire scrub.
• Lane-to-lane turning.
• Improved maneuverability and safety.
• Pierce, single-source manufacturing.
