INTRODUCTION
SERVICEOur commitment to outstanding service has been the main reason for our consistent growth since 1977 as we recently built a much larger manufacturing facility to maintain this level. When it comes to service, we have one goal — to provide the best in the industry. Absolutely no one ships hot jobs quicker. We can do this by stocking the raw materials we need and operating only one full shift in our manufacturing plant. This allows us the
key equipment and material when hot jobs are ordered. We have a full engineering staff on hand capable of performing
questions you may have.
QUALITYWhen it comes to quality, we will put our products up against anyone in the industry. Prior to manufacturing, all custom conveyor designs must pass a computer stress analysis covering
shafts. On request, this information can be provided at time of quotation. Our components are manufactured in-house allowing us to keep tight reign on quality control and must pass a full inspection prior to shipping.
PRICEOur stainless conveyors are built entirely under our roof. You will not pay multiple markups for subcontracted parts. We handle complete manufacturing and engineering functions through our facility in Cedar Rapids. This means that, even with industry leading standards for quality and service, we can still offer very competitive pricing.
REFERENCESOur customer base has grown over the years primarily by word
opportunity to work with companies such as:
Again, thank you for the opportunity to get to know us better — we are very proud of the work we do and look forward to working with you.
in stainless steel screw conveyors, presses used in a variety of industries. The cornerstone of our success for over three decades has been our ability to provide a quality product at a reasonable price in a timely manner.

troughs, surface hardeners or special alloy components. (see Abrasion, p.27
Contaminable materials, such as certain chemicals and food additives, require the use of sealed end bearings and hanger bearings of wood, nylon or other dry operating type. Trough covers should be tightly sealed and easily removable for frequent cleaning and all the internal welds that contact the material may require polishing to eliminate material entrapment.
Materials that tend to break up or separate should be carried in

SCREW STRAIGHTENING & SHAFT RUN-OUT
screw turns "true" with its shafts. A screw that is properly straightened will result in longer life of coupling bolts, hanger bearings, end
their lower ability to handle fatigue stresses. After straightening, a coupling shaft is bolted in and the screw is rotated while a dial indicator measures run-out at a point 10" from the center of the bearing area.

DROP BOTTOM / CHANNEL TROUGH:
Also allows for bottom of trough to be removed for cleaning or replaced if worn from abrasive materials.
JACKETED TROUGH: Jackets may be added to any trough style to provide heating or cooling during conveying using hot or cold water or low pressure steam in jacketed area.

TROUGH END PLATE WITH FOOT: Our most common end plate design for U-troughs. The integral foot design eliminates the need for saddles or feet at the screw conveyor ends. Also provides additional structure for support of drive mechanisms. Can be ordered with pedestal bearing mounts.
TROUGH END PLATE WITHOUT FOOT: Can be used when other means of support are provided, such as saddles.
FLARED TROUGH END PLATE WITH FOOT: Used in the same situations as
mounts.
TUBE TROUGH END PLATE WITH FOOT: The integral foot eliminates the need for saddles at the end of tubular trough screw conveyors. Can be ordered with pedestal bearing mounts.
TUBE TROUGH END PLATE: Used when other means are provided for trough support. This end plate allows ease of maintenance when a the trough end. The end plate can be removed without providing temporary trough support.
TROUGH END PLATE WITH FOOT AND PEDESTAL BEARING MOUNT: The pedestal pillow block mount allows clearance for packing gland seals or when frequent seal maintenance is required. This is also useful for bearing isolation from damaging
styles.

FLANGED COVER:-
FLAT OR SEMI-FLANGED COVER: Works well with spring clamps but supports
bolted in place properly so they are only recommended under special circumstances.
HIP-ROOF (RIDGED) COVER: Recommended for outdoor applications to help
Can be gasketed for additional protection.
FLARED TROUGH COVER (FLANGED):
SHROUD: U-troughs when a tubular trough is needed but
applications may call for the shroud to be continuously welded to a cover.
DAM:
with materials that tend to clump together.

When necessary, screw sections are typically removed starting with the end opposite the drive. Remove trough end, screw sections, coupling shafts, and hangers until damaged or worn section is removed. Reassemble conveyor in reverse order.
Periodically remove and inspect one of the drive shaft coupling bolts for damage or wear. Also inspect the coupling bolt hole. The drive shaft coupling bolts transmit more power than successive coupling bolts and will typically indicate the greatest wear. An accurate torque
