buildings? If so, describe.
Describe visible damage, if any.
Describe alignment issues, if any.
Conveyor Angle
Incline, decline, or flat?
Continuous angle? Or horizontal loading and
unloading with incline in between (causing belt
to lift off idlers)?
Guarding
Is guarding visually noticeable?
Is guarding adequate at the load zone?
Is guarding adequate at the gravity take-up?

protection?
Can operators reach through or around
guarding to access conveyor components?
Is guarding located a sufficient distance from
moving equipment to provide safety?
Does guarding require a tool to remove?
Guarding continued
Are return rolls below 7 ft. guarded?
Do return rolls over roads, walkways, or
buildings have roller baskets?
Emergency Stop Switches
Is the entire length of the conveyor covered by
cable or guarded?
Are the emergency stop switches functional?
Are the clamps correctly installed?
Does the cable have too much slack?
Are there at least two connectors?
Take-up
Type (gravity, power, screw)?
Is it level? Does it apply consistent force on
both sides of the belt?
Does it function smoothly? Are the guides
inline and free to operate?
Belting
Type of belt (steel, cable, multi-ply)?
Is the belt adequate for the application and
existing conditions?
Belt condition? Does it show signs of surface
damage? Edge damage from mistracking?
“Skirtboard gouge” from sealing system and
entrapped material? Describe.
Visible rip or rip repairs?
Other problems? Camber? Various
thicknesses spliced together? Describe.
Splices
Type of splice? Number of splices?
Condition of splice?
Does splice “clank” when it travels over idlers?

Belt Tracking
Is mistracking visible? Loaded or unloaded?
If belt mistracks, does the mistracking occur all
along the belt? At one point on the structure?
At one point on the belt?
Is there a training device as the belt enters the
tail pulley? the load zone?
Is the belt centered as it enters the load zone?
Does the loaded belt track in the center?
Does the unloaded belt track in the center?
Fugitive Material
Characteristics (wet, powder, chips, lumps)?
Where does fugitive material accumulate?
Sources (carryback, spillage, dust, throw-off)?
Is there dust or build-up on adjacent structures
and equipment caused by fugitive material
from this conveyor?
Tail Pulley
Is the tail pulley a wing style? If so, is it
wrapped?
Is there material build-up on the tail pulley?
Does the tail pulley add vibration to the belt?
Is there a plow on the return belt prior to the
tail pulley?
If so, what is its condition?
Transition Distance
What is the distance between the tail pulley
and the first fully-troughed idler?
Is the belt fully troughed when loaded?
Tail Seal
Does material roll down and off the belt at the
back of the load zone?
Is there a tail box? If so, is the back seal
effective?

Loading Chutes
Is there more than one loading point?
If so, do they all load at once? or in
sequence?
Is there a strong air current with dust from the
conveyor or crusher above?
Does the chute have holes from rust and
abrasion?
Are there enough doors for inspection and
service? Are they conveniently located?
What is the drop height?
Is there a heavy impact or “splash” as the
material loads the belt?
Does the material load in the direction that the
receiving belt is moving?
Is the load centered on the belt?
Does loading segregate the material by size?
Does the belt rise from the idlers at start-up
(when partly loaded)?
Belt Support
Is there belt sag between idlers?
Are idlers all the same manufacturer, type, and
size?
Does high material impact cause idlers to be
replaced frequently?
Are impact cradles and support cradles
serviceable?
Wear Liner
Liner material? Condition?
Typical liner life?
Distance from bottom of liner to belt?
Does the liner relieve toward the exit?
Is the liner properly installed? (no “saw tooth”
to catch material)

Edge Seals
Are edge seals effective?
Are edge seals properly adjusted?
Is the sealing strip continuous from the tail box
through both sides of the load zone?

has this grooved the belt?
Enclosure
Length of enclosure? Height of enclosure
above cargo?
Is the load settled before it leaves the
enclosure?
Is there a strong current of air (and dust) at the
exit to the enclosure?
Are exit curtains are installed?
Condition of curtains?
Conveyor Cover
Is the conveyor covered?
If so, is the cover in place?
Walkway
Is the walkway on one side or both sides of the
belt?

the walkway?
Carrying Idlers
Does the belt lay on the carrying idlers when it
is loaded? when it is unloaded?
