CRANE INSTALLATION 500E2 SERVICE MANUAL
Configuration 2 - 571E2
This mount requires single front outrigger (SFO) and
additional counterweight in the underside of the bed for full
capacity 360× around the truck. The SFO gives the machine
a solid base helping the operator control loads.
Requires 12,000 pound (5443 kg) GAWRF, 21,000
(9,525 kg) GAWRR, 33,000 (14,968 kg) GVWR, standard
sub-base for 20 ft bed, SFO and ASH rear stabilizers and
usually requires concrete counterweight in the torsion box
between the crane and the ASH. Counterweighting in this
manner reduces the loading induced on the SFO when lifting
over the front. Truck must have 15.9 in
3
(261 cm
3
) section
modulus and 1,749,000 in-lb (197,610 N-m) RBM or be
capable of being reinforced to this strength under the crane
frame through to the front suspension. Normally a tapered
frame cannot be reinforced to this requirement. The frame
strength requirements for the remainder of the truck frame
are the same as in Configuration 1. Tandem axle trucks may
be used for hauling larger payloads.
