MOUNTING CONFIGURATIONS
The Series 800D is a versatile machine and its versatility can 
be enhanced by the manner in which it is mounted. Following 
is a brief description of the mounting configurations and the 
advantages of each. The minimum weights listed below the 
front and rear axles for each configuration are estimated 
minimum front and rear axle weights for an 85% stability 
factor before the crane, stabilizers and subbase, if required, 
are installed on the chassis. Truck chassis that do not meet 
these minimum stability weights may require counterweight. 
These weights include the permanently attached equipment 
on the chassis, such as pumps, PTO’s, reinforcing, chassis 
mounted options, bed and counterweight. Before placing this 
unit in service, a final stability check as outlined in this 
section must be performed. The maximum weights listed 
below the front and rear axles for each configuration are 
estimated maximum front and rear axle weights for not 
exceeding axle capacities before the crane, stabilizers, and 
subbase, if required, are installed on the chassis.
Configuration 1 — 8100D
This configuration allows the installation of the Series 8100D 
on a chassis by using the sub-base for a 22 ft bed. In most 
cases, the chassis will not require reinforcing.
Requires 16,000 lb (7257 kg) GAWRF, 34,000 lb (15 422 kg) 
GAWRR, 50,000 lb (22 679 kg) GVWR, RSOD rear 
stabilizers and sub-base for 22 ft bed. Full capacity work 
area is rear 180° of vehicle from outrigger to outrigger. Truck 
frame must have or be capable of being reinforced to 
15.9 in

 S.M. (260 cm

) and 1,749,000 lb-in (197 610 Nm) 
RBM under the crane, spring hang Oerto spring hanger.
*Actual scale weights prior to installation of crane, sub-base 
and stabilizers.
**If the distance from the front bumper (SFO) to center of 
rotation exceeds 144 in (366 cm), the 40 ft (12.19 m) overall 
truck length restriction will be exceeded. Overall length 
restrictions vary from state to state. In some states it is legal 
to be more than 40 ft (12.19 m) in length and some states 
allow overlength permits.
Configuration 2 — 8100D
This mount requires front stabilizer for full capacity 360° 
around the truck. Front stabilizer gives the machine a solid 
base helping the operator control loads.
