 Caldwell's
horizontal chain conveyors are built to satisfy your needs. A flexible
design allows several options in constructing the conveyor that
will fit most applications. A combination of exterior gauging, replaceable
abrasion resistant liners, chain types, sprocket options, paddles
and speed requirements are offered to provide quality service in
many applications for years to come. Heavy duty purchased components
along with manufactured components fabricated on hard tooled multiple
punching fixtures, numerical controlled punching machines, and fixture
welded assembles ensure ease of assembly and years of performance.
With Caldwell's years of experience and knowledge on different materials,
we stand ready to design and build a conveyor for your application.
 A
bolt on panel is provided which can be removed so the shaft, bearings
and sprocket can be lifted out as one unit.
Two styles of chain returns are offered. UHMW Idlers are typically
used for conveyor widths of 8.75" up to 16.75". Angle
return rails are used on 16.75" and wider.
The integral staggered seam construction provides a flush connection
throughout the interior of the conveyor. Since there is no welding
at the intermediate connec¬tions, the galvanized intermediate
sections will provide a maintenance free exterior for many years
to come.
Depending on thee application, a medium duty series 300 ball bearing
pillow blocks or double row spherical or tapered roller bearing
pillow blocks are used.
 Caldwell
offers 3 types of chain. The fmt chain is a 2.61" pitch steel
bush raller chain mat is used in me smaller capacity conveyors.
The 2.61" pitch raller chain has a one-piece raller, many chains
of this size have a seam in me raller which increases wear and leads
to an earlier failure. F or larger capacity and longer length conveyors
a 3.75" pitch engineering class steel bush taller chain is
supplied. The third chain offered for me highest capacity and longest
conveyors is a 6" pitch knuckle chain. The pin and raller are
combined for increased strength and to assure long life. The 3.75
pitch and 6.0' pitch chains are bom engineering class chains. These
chains have press fit links to minimize wear and increase strength.
All chains have hardened pins, rollers and sidebars.
 A
choice of material is offered for me conveyor paddles depending
on me application. As standard, a virgin UHMW paddle can be used
in thicknesses of 1/4" (6.4mm), 3/8" (9.5mm), and 1/2"
(12.7mm). Nylon or steel paddles are also available depending on
application. (3.75 Steel Bushed Roller Chain shown.) Nyloc locking
nuts are used for paddle attachment. The nylon inserts insures me
paddle will not come loose. |
