ATEC WEIGHT DISTRIBUTION
The ATEC with all of its components and options presents a number of variations in axle weight
distribution and gross vehicle weight. In many cases, highway travel and vehicle loading
requirements restrict the ways in which the vehicle can be configured. In such cases, it may be
necessary to reconfigure the ATEC. The following are examples of different ways that the ATEC
can be configured. The front and rear axle loads and the gross vehicle weights have been
calculated for each configuration. Calculations have also been included to show how certain
components affect the axle loads and gross vehicle weight.
NOTE
All weights are in pounds.
The maximum allowable front and real axle loads for
55 mph travel are 22475 pounds (each).

ATEC in the As Shipped Configuration. The ATEC as shipped (e.g., with the hose reel,
outrigger pads, and spare tire installed; tie-down shackles, spare tire handling sling, and tire
inflation kit in front storage box; and fuel and hydraulic tanks full), weighs:
FRONT AXLE
REAR AXLE
GROSS WEIGHT

2.
ATEC Rigged for Heavy Lifting. To configure the ATEC for heavy lifting, the hoist cable
and the 22-ton hook block must be installed. Installing these components results in the following
weight configuration:
FRONT AXLE
REAR AXLE
GROSS WEIGHT
Install main hoist cable
-205
+511
+306
Install 22 ton hook block
+1047
