STACKABLE
CONVEYOR WIDTHS
Belt widths of 24", 30" and 36" are standard. Other widths are available
upon request. See Table A.
STACKABLE CONVEYOR LENGTHS
Standard conveyor lengths are 40 ft. through 72 ft. in 4'-0' increments. Other lengths are
available upon request. See Table A.
STACKABLE CONVEYOR FRAME Truss type, constructed entirely of tubular members. Chords are
square tubing, while all other members are round. Unique design provides for 4 1/4 "
clearance from belt edge to nearest truss member (when belt is centered). Round side frame
members (as compared with sharp leg of angles) provide further belt protection. Complete
truss is 2'-0" in depth, allowing for a "stack" of four conveyors on one
trailer, and widths through 36" provide for two conveyors (side-by- side)-thus eight
36" stackables on one truckload, within legal height and width.
STACKABLE CONVEYOR - HINGED
MODEL
A hinged joint can be furnished in any location in 4 ft.
multiples along the conveyor length. Hinge provides for "Tail End" folding.
Minimum folded section is 10 ft. (14 ft. if conveyor loading hopper is extended an
additional 4 ft.).
PULLEYS
Heavy duty, all steel welded type, individually turned and crowned to ensure true
concentricity with the bore. Faces of the pulleys are machined. OSHA/MSHA pulley guards
and tail pulley cage are standard.
RUBBER LAGGING FOR HEAD PULLEY
Heavy duty, top quality "Ruff Top" rubber lagging furnished on crown face
pulley. Installed in multiple widths to ensure conformity to crown face.
IDLERS
MARCO Series M15 - 4 1/2' dia. rolls, with pre-lubricated
ball bearings which require no further lubrication. Troughing Idlers are spaced on
4'-0" centers with two extra at the loading point; return idlers are spaced on
10'-0" centers. 35o idlers are standard. Impact idlers and self-aligning return idlers
are available as optional equipment.
BELT TAKE-UP
Screw type, acid cleaned and plated, providing 18" adjustment.
RETURN BELT WIPER
"Plow type", equipped with gum rubber flashing, and is mounted in front of tail
pulley to prevent entrance of material between return belt and pulleys. Wiper is provided
only when tail pulley is solid (as opposed to self-cleaning). |

CONVEYOR
DRIVE
Drive includes shaft mounted helical gear speed reducer (gears are enclosed and running in
oil), driver and driven sheaves and vee belts. All drive components are selected to
adequately transmit horsepower required. OSHA/MSHA drive guard is standard.
ELECTRIC MOTOR
Horsepowers vary with capacity, length and incline. Motor sizes are selected with ample
safety factors to provide an efficient and reliable power source. 1800 RPM, TEFC, Nema
design "C", hi-torque, 3 phase, 60 Hertz, 230- 460 volt motor is considered
standard.
CONVEYOR BELT The use of 35o troughing idlers on 4 ft. centers provides ideal conditions for the
use of belts with synthetic fabrics. Strength of fabric, number of plies, and thickness of
rubber top and bottom covers, are combined to ideally satisfy the installation
requirements.
OPTIONAL SPECIFICATIONS
CONVEYOR SPAN AND CONVEYOR SUPPORTS
Spanability varies with load conditions, weight of
material, belt width, accessories, etc. Forward supports are adjustable, with telescoping
legs. See standard support groups.
BACKSTOP
When conditions indicate the belt and load will reverse under power failure, a backstop
should be selected. Backstop is mounted in the shaft mounted reducer, and runs in oil.
BELT WIPER (for Head Pulley)
Equipped with double rubber squeegee and adjustable tension springs, providing constant
pressure on belt surface. Mounted under pulley to provide greatest efficiency.
RUBBER DISC IMPACT TROUGHING IDLERS
Three rubber disc impact troughing idlers can be furnished in place of standard troughing
idlers.
SELF-ALIGNING RETURN IDLERS
Self-aligning return idlers can be furnished for alignment of the return belt.
LOADING HOPPER EXTENSION
Basic loading hopper can be extended 4 ft., making a total length of 9 ft.
LOADING BOX FOR TAIL -
(EXTENSION OF STANDARD LOADING HOPPER
Loading boxes will accept, and center, material coming from any direction. Loading box
must be removed for transport.
