Built Crown Toug
for the Long
Observe tuggers in any application and you’ll see constant jerks, jolts and impacts they must
endure everyday. Crown’s TR 4500 Series combines robust components and a heavy-gauge
steel design to withstand the rigors of the toughest applications.
Towing a rolling load with a
capacity of 10,000 pounds
over and over demands a
heavy-duty drive unit with
a powerful motor.
Open the doors of the TR 4500
and you’ll see that our Crown-built
drive unit and AC motor is the
industry’s largest—offering you
unmatched durability and power.
The drive unit is secured at the
top and bottom for increased
life. Large tapered roller bearings
at the top absorb vertical and
horizontal forces. Four shockmounted rollers at the bottom
turn in a hardened steel roller
race to further support the
drive unit and absorb shock.

Crown’s AC drive motor is
mounted horizontally and sized
right to provide high torque,
greater draw bar pull and long
life. The e-GEN® braking
system uses the powerful
torque of the AC motor to
deliver consistently reliable
frictionless braking for the life
of the truck. A park brake on
the end of the motor applies
automatically after the truck
comes to a stop.
