MIL-W-43001F
3.5.2.8 Cylinder drive.  The cylinder of each washer-extractor shall be
electrically driven through V-belts or a combination of gearing with V-belts to
provide proper cylinder speeds for the washing and extracting cycles.  A low
speed pre-extract cycle, except for 25-, 50-, and 100-pound size, shall be
provided.  An intermediate load positioning cycle (approximately double the rpm
of the washing cycle) will be acceptable for the 200-pound size in lieu of a low
speed pre-extract cycle.  This cycle shall be accomplished through a change in
the drive ratio, by changing the speed of the washer or extractor motor, or by a
separate motor.  A low speed pre-extract cycle shall be accomplished with the
quick-opening drain valve or valves in the open position.  These requirements
shall be verified when the equipment is tested as specified in 4.6.1 and 4.6.2.
3.5.2.9 Inching or positioning.  The divided cylinder washer-extractors shall
have provisions for two-way inching in both the up and down directions for
positioning the cylinder doors in the loading and unloading position for each
compartment and securing the cylinder in these positions, including gravity
loading by sling or chute when the shell door is open.  Inching or positioning
q eans shall require the operator to use both hands on pushbuttons to inch or .
position the cylinder.  These requirements shall be verified when the equipment
is tested as specified in 4.6.1.
3.5.2.9.1 Automatic inching or positioning (divided cylinder machines only).
When specified (see 6.2), divided cylinder washer-extractors shall be provided
with automatic inching or positioning of the cylinder doors to each loading and
unloading position for each compartment in addition to manual inching specified
in 3.5.2.9.
3.5.2.10 Cylinder bearings.  Each machine shall have a replaceable type
bearing, or bearings, supporting the cylinder  Cylinder trunion bearings for
divided cylinder machines shall be self-aligning, antifriction type.
3.5.2.11 Braking.  The braking system on all washer-extractors shall be of
the electro-mechanical, electro-magnetic, hydraulic, or pneumatically operated,
heavy duty type that will stop the cylinder, when loaded to full capacity, from
extracting speed in less than 60 seconds and (except for one compartment
machines) hold the cylinder in a steady position for loading and unloading.
This requirement shall be verified when the equipment is tested as specified in
4.6.2,  A break interlock switch shall be provided and shall prevent operation
of the cylinder when the brake is applied (except for inching or positioning -
see 3.5.2.9),  This requirement shall be verified when the equipment is tested
as specified in 4.6.1.  Brake linings shall be replaceable.
-
3.5.3 Type III  pass through (loading and unloading isolated).  The type III
washer-extractor shall be designed for installation in partition walls.  The
machine shall be equipped with a loading door on the pre-wash side of the
machine and partition and an unloading door on the post wash and extract side of
the machine and partition.  Except as specified hereinafter, the machine shall
conform to 3.1 through 3.5.1.7 and 3.5.1.9 through 3.6.7.
