1 General safety and design
considerations
1. 1 I n t r o d u c t i o n
1. 1. 1 C r i t i c a l f a c t o r
To achieve an operational installation which is reasonably safe for all people
involved in its use and maintenance, it is necessary to consider certain as-
pects. This is done when designing a conveyor system. The chain is gen-
erally the critical factor to consider with guarding.
1. 1. 2 S a fe g u a r d i n g
All pinch and shear points as well as other exposed moving parts that pres-
ent a hazard to people at their workstations or their passageways must be
safeguarded. Overhead conveyors must be guarded to prevent objects fall-
ing. Cleated conveyor chains are more hazardous and create more pinch
and shear points than plain conveyor chains.
General safety and design considerations
25814EN-05
1.1.2.1 Safeguarding can be achieved by:
• Location
Location of all hazardous areas away from areas occupied by
personnel, wherever possible.
•Guards
Mechanical barriers preventing entry into hazardous areas or
protecting against falling objects.
• Control devices
Machine controls which prevent the interruption of hazardous
operations/conditions.
Warning: Instructions, warning labels, or sound/light signals which alert to
hazardous conditions.
Safeguarding should be designed to minimize discomfort or difficulties to
the operator. Bypassing or overriding the safeguarding during operation
should be difficult.
Warning labels etc. should only be used when all other means of safe-
guarding will impair the function of the installation or are not cost effective.
The degree of safeguarding required should be identified during the imple-
mentation of the essential safety requirements during the design process.
1.1.3 Special considerations
When correctly applied, the FlexLink components are safe to use and
maintain. It is however necessary for those responsible for design, instal-
lation, operation and maintenance of the FlexLink installation to be aware
of certain areas where special attention is required.
1.1.3.1 All drive units with slip clutch
• Before adjusting the slip clutch it is necessary to remove all ob-
jects from the chain to remove any remaining chain tension.
• Adjustment should be conducted in accordance with the mainte-
nance procedures.
• All drive units, except the direct drive units, are fitted with trans-
mission chain covers.These covers must be fitted before the unit
is operated.
NB: The slip clutch is not a personnel safety device, but a device to protect
the conveyor equipment.

2 Safety
The machine has been designed in such a way, that it can be used and
maintained in a safe way. This holds for the application, the circumstances
and the instructions described in this manual. Any person working with or
around this machine should study the manual and follow the instructions.
It is the responsibility of the employer to make sure that the employee is
familiar with, and follows, these instructions.
The company or the country in which the machine is used may require ex-
tra safety measures. This particularly applies to the working conditions.
This manual does not describe how these are to be complied with. In case
of doubt, consult your government or safety officer!
2.1 System information
The order number and/or general drawing number shall always be speci-
fied when communicating with FlexLink with respect to the machine.
2.2 Important safety conditions
Before the machine shall be operated by a user, the following safety con-
ditions must be met:
Make sure that children or animals have no access to the machine and its
surrounding areas by, for example, screening off the machine with a fence.
Only personnel who have read and understood the operating instructions
are allowed to operate, maintain and clean the machine.
Do not reach into the machine while it is running or on. Even if the machine
is not running, it can be ‘on’, which means start operating automatically.
Safety provisions, such as side guards, bottom guards, emergency stops
and detectors shall not be removed or deactivated while the machine is
running.
Provide good ambient lighting to enable the operator to work well and or-
derly with the machine.
Safety
45814EN-05
2.2.1 General
• Incorrect use of the equipment can cause personal injury.
• Do not stand or climb on the equipment.
• Do not wear clothing or other articles that can fasten in the ma-
chine.
• For coupled drive units, safety protection should be applied to the
connecting shaft.
2.2.1.1 End drive units
• The chain slack length at the end drive units must be maintained
during the system lifetime. Shorten when necessary
• If side plates are fitted, the chain must be shortened if the chain
becomes visible below the level of the side plates.
• The opening and closing of the links when they turn round the end
drive and idler wheels could be a risk. Drive and idler ends should
not be accessible during conveyor operation wherever possible.
The area near the in-feed guides for the chain return loop should not be ac-
cessible during conveyor operation.
2.2.1.2 Intermediate drive units
• The area near the in-feed guides for the chain return loop should
not be accessible during conveyor operation.
2.2.1.3 Horizontal bend drive unit
• The drive wheel should not be accessible during conveyor opera-
tion. The bottom should be covered with wheel cover.
2.2.1.4 Idler units
• The opening between the links when they turn round the idler roll-
er could be a risk. Idler ends should not be accessible during con-
veyor operation wherever possible.
2.2.1.5 Wheel bends, horizontal and vertical
• Guarding may be required at wheel bends depending on location
of bends and load applied to the conveyor.
• The opening between the links when they turn round the idler roll-
er could be a risk. Idler ends should not be accessible during con-
veyor operation wherever possible.

2.2.1.6 Cleated chains
• Any application incorporating cleated chains requires careful safe-
ty consideration. Pinch and shear points are generated through-
out the assembly of the incorporated components. Therefore
generous guarding should always be employed to fully protect
within user operating areas.
• There is a higher risk of product damage when using cleated
chains. Special attention must be given to operator access in the
event of products becoming trapped or similar.
2.2.1.7 Maintenance
The maintenance routine of FlexLink conveyors should also include proce-
dures to ensure that the guarding remains securely fastened and effective
(if not interlocked via control system etc.).
FlexLink components are continuously reviewed to improve performance
either by design modification or material upgrade. In all these reviews user
safety is our primary consideration.
All associated technical data are retained at the manufacturers address.
2.2.1.8 Control system
Before operating or completing any maintenance on control system, read
the associated section as supplied with the equipment documentation.
If there are any questions as to the safe operating procedures of the equip-
ment supplied, please contact FlexLink immediately.
• Follow the instructions in this user manual when transporting the
machine. FlexLink AB must approve all modifications or changes
to this machine.
• Only use recommended spare parts.
• Only authorised personnel may open electrical units.
• FlexLink is not responsible for damage if service on the equip-
ment is not performed in accordance with this user manual.
