The minimum turning radius when measured at the center of the outside
tire shall be not less than 17’ 8".
The frame shall articulate not less than 38.5 degrees in either direction.
Articulation shall be effected by two (2) double acting cylinders with
hardened chrome plated piston rods. The cylinders shall have a bore and
stroke of not less 2.76" x 17.8".
LOADER MECHANISM
The loader lift mechanism shall be of the single bellcrank, "Z-bar" type. It
shall have not more than thirteen (13) pivot points. All pivot points shall
be equipped with sealed linkage pins. Pivot point lubrication shall be not
more frequent than every 250 hours.
The lift boom arms shall be of a heavy duty, single plate design. They
shall be fabricated from high tensile strength steel and shall be designed
to withstand maximum stress.
Boom lift shall be affected by two (2) cylinders with a bore and stroke of
not less than 4.7" x 28.7". Bucket tilt shall be affected by a single cylinder
with a bore and stroke of not less than 5.9" x 22". All cylinders shall be
double acting with hardened chrome plating on the piston rods.
The loader boom lift cylinders and the bucket tilt cylinder shall be
controlled by a “mono-lever” type control located to the operator's right. It
shall include an integral forward/reverse switch. A second lever shall be
provided to control any attachments such as a multi-purpose bucket. A
safety lock shall be provided for the loader control levers.
The loader control levers shall employ a pilot control system. A dedicated
pilot pump shall provide flow to a proportional pressure flow valve. This
system shall permit one handed control of loading operations.
The loader lift mechanism shall be equipped with a "Rap-out" design
linkage. This design shall permit shock dumping to remove sticky
material.
The loader lift mechanism shall be equipped with an automatic bucket
positioner. This device, which shall stop the bucket automatically at the
desired digging angle, shall employ a proximity switch and a bucket
control lever on the bucket tilt cylinder. The positioner may be reset
manually to meet the digging angle requirement of a particular job.
The loader lift mechanism shall be equipped with an automatic boom
kickout. This device, which shall stop the boom at the desired lifting
height, shall employ a proximity switch and an arm control lever, which
shall be mounted on the boom arm. The kickout may be reset manually if
desired.
BRAKES
The wheel loader shall be equipped with four (4) wheel, hydraulic,
inboard mounted wet disc type service brakes. The service brakes shall
be controlled by two (2) pedals. Both pedals shall be used for braking. A
selector switch shall be provided to allow the left pedal to be used to
neutralize the transmission.
The wheel loader shall be equipped with a wet disc type parking brake,
which shall be located inside the transmission case. It shall be spring
applied and hydraulically released. The parking brakes shall be self-
adjusting.
