Payload Volume/Soil Density Relationship
CCE-IHC Dump Truck is limited physically to 71,000 lb.
GVWR.
Heaped CCE-
IHC Dump Truck payload at 15 cy:
@3000 lb/cy
@2600 lb/cy
@2200 lb/cy
Payload
45,000 lb.
39,000 lb.
33, 000 lb.
Curb Wt
31,000 lb.
31,000 lb.

(Overload by 5000 lb.)
Struck CCE-IHC Dump Truck payload at 12 cy (level-off body by dragging bucket
across top of load at body side height):
@.3000 lb/cy
@2600 Ib/cy
@2200 lb/cy
Payload
36,000 lb.
31,200 lb.
26,400 lb.
Curb Wt

31,000 lb.
31,000 lb.
GVW
67,000 lb.
62,200 lb.
57,400 lb.
Therefore, to avoid overloads, (1) determine the weight of 1 cubic foot of payload aggregate at X lb., (2) multiply by 27 to
get the approximate weight per cubic yard, (3) read the GVW of the truck and payload, and (4) compare with the lowest
capability of the route to be traveled.
This determines whether the CCE-IHC Dump Truck haul is to be run at heaped
capacity or at struck capacity.
