Operating Capacity
The operating capacity is a percentage
of the machine’s tipping load. Tipping
load refers to the amount of weight
required to tip the machine forward when
applied to the center of gravity of the
standard dirt bucket.
This rating is calculated with the machine
on level ground and the bucket attach-
ment installed, curled and raised until at
its furthest point from the machine in the
lift arm travel path.
The Rated Operating Capacity is then
calculated as 35% of the tipping load for
traditional track loaders and 50% of the
tipping load for wheeled skid steer load-
ers. ASV publishes both figures for refer-
ence and comparison.
Note:
SAE J818 standards define oper-
ating capacities of rubber-tired skid
steers (50% tipping load) and tracked
loaders (35% tipping load). There are no
standards defining the operating capacity
of machines equipped with a suspended
undercarriage or machines with rubber
tracks.
Gross Vehicle Weight
The GVW (Gross Vehicle Weight) of the
PT-50 or PT-60 should not exceed 8,500
lbs. This weight does not include an
operator, but does include any acces-
sories, attachments or material being
carried. Operating the machine in excess
of the GVW will void the warranty (see
page 2).
