This
Document Is Designed To Highlight The Parts Of A Conveyor That
May Need Attention During Their Working Life. Permission For
The Removal Of Parts Or Product Modifications Must Be Sought
Before Any Work Is Carried Out

Cleaning
It Is The Clients Responsibility To Ensure That The Product
Is Cleaned In The Correct Or An Appropriate Way. Eg, Mild/Carbon
Steel Should Not Come In Contact With Any Form Of Liquid As
It Will Lead To Rusting (All Our Mild Steel - Self Colour
- Gravity Roller Conveyors Are Despatched With A Coating Of
Oil To Initially Protect Them From The Elements, If There
Is The Possibility Of Water Or Moisture, Then An Alternative
Option Should Be Considered At The Quotation Stage - This
Also Applies To Any Product Or Component Of A Product That
Is Self Colour Mild Steel). Electric Controls And Panels Should
Not Be Washed Down Unless A Specific IP Rating Has Been Stated
At Quotation/Order Stage.

Gravity
Roller (Unpowered) Conveyors
Visual
check for wear or damage
Check alignment, levels and squareness
Check movement of rollers and bearings
Check nut/bolt tightness in side frames and supports
If the rollers or any metal parts are mild steel (uncoated/unprotected
via plastic, zinc etc), make sure there is no contact with
water or any form of liquid without first seeking our advice
|

Lineshaft
Driven Roller Conveyors
Visual
check for wear or damage
Check alignment, levels and squareness
Check movement of rollers and bearings
Check nut/bolt tightness in side frames and supports
Check for noisy drive units, lubricate drive chains from motor
unit to lineshaft, check tension and adjust if required
Check for sprocket wear
Check motor oil level - Drain and replenish motor gear box
oil to manufacturers recommendations
Check bearings for wear, check grub screws are secure
Remove excess oil from exposed parts of lineshaft
Check ancillary equipment (transfer units, pneumatic stops
etc) for wear and tightness
Check all pneumatic parts for wear and leaks
Check side guides are secure and tight
Check any electrics (start/stops, emergency stops, photo cells,
etc) are secure and working
If the rollers or any metal parts are mild steel (uncoated/unprotected
via plastic, zinc etc), make sure there is no contact with
water or any form of liquid without first seeking our advice

Belt
Conveyors
Visually
check for wear and damage
Visually check that framework and guides are secure, feet
stable and conveyor is safe to operate
Visually check that all safety guards are fitted and secure
Examine belt for wear and damage, clean if practical
Check belt fastener/vulcanised joint, check belt tracking
and tension, adjust if required
Check for noisy drive units, lubricate drive chains from motor
unit to headshaft, check tension and adjust if required
Check for sprocket wear
Check motor oil level - Drain and replenish motor gear box
oil to manufacturers recommendations
Check bearings for wear, check grub screws and fixing bolts
are secure
Check all rollers are secure and revolve properly
Check ancillary equipment (transfer units, pneumatic stops
etc) for wear and tightness
Check side guides are secure and tight
Check any electrics (start/stops, emergency stops, photo cells,
etc) are secure and working
If the rollers or any metal parts are mild steel (uncoated/unprotected
via plastic, zinc etc), make sure there is no contact with
water or any form of liquid without first seeking our advice

Personnel
Gates
Visual
check for wear or damage
Check alignment, levels and squareness
Check bearings for wear, check grub screws are secure
Check lifting is free without using excess effort up or down.
If gas struts are fitted and the gates require excessive force
to close, the gas may need to be bled. If gates need excess
force to open, struts may need to be replaced
Remove excess oil from exposed lineshaft
Check movement of rollers and bearings, check drive belts
for wear
Check nut/bolt tightness in side frames and supports
If the rollers or any metal parts are mild steel (uncoated/unprotected
via plastic, zinc etc), make sure there is no contact with
water or any form of liquid without first seeking our advice

Pneumatics
Drain
moisture from in-line filter regulators
Check and refill oil in lubricators
Visually inspect nylon tubing for wear and loose fittings,
replace bad joints
|
|
Electrics
Visually
check system for broken buttons, E/Ms, boxes etc. Check all
trunking/conduit is secure and lids are fitted
Check panel is secure and system runs correctly

RATING STANDARDS
An
IP number is often used when specifying the environmental
protection afforded by enclosures around electronic equipment.
These ratings refer to specific tests. The IP number is made
up of two components as follows: IP44 The first number refers
to the protection against solid objects and the second against
liquids. The higher the number the better the protection.
see below for a summary.
IP
PROTECTION NUMBER SUMMARY:-
|
| FIRST
NUMBER
0
- No Protection
1 - Protected Against Solid Objects Up To 50mm - Eg, Accidental
Touch By Hands
2 - Protected Against Solid Objects Up To 12mm - Eg, Fingers
3 - Protected Against Solid Objects Up To 2.5mm (Tools And
Wires)
4 - Protected Against Solid Objects Up To 1mm (Small Tools
And Wires)
5 - Protected Against Dust, Limited Ingress (No Harmful Deposit)
6 - Totally Protected Against Dust
|
| SECOND
NUMBER
0
- No Protection
1 - Protection Against Vertically Falling Drops Of Water -
Eg, Condensation
2 - Protection Against Direct Sprays Of Water Up To 15 Degrees
From Vertical
3 - Protection Against Direct Sprays Of Water Up To 60 Degrees
From Vertical
4 - Protection Against Water Sprayed From All Directions -
Limited Ingress Permitted
5 - Protected Against Low Pressure Jets Of Water From All
Directions - Limited Ingress Permitted
6 - Protected Against Low Pressure Jets Of Water (Use On Shipdeck)
