10.2 Inspection
Conveyor chain
Inspect the conveyor chain regularly, every 1,000 hrs, for ease of movement,
suffi cient lubrication and wear. Inspect more frequently, e.g., every 500 or 200 hrs,
when using production processes that include rinsing, fl uid transfer, etc. in which
the lift transverse unit chain could be washed out.
Lift unit
Regularly check the pneumatic connections for leaks.
10.3 Maintenance
Sudden movements, falling workpiece pallets
Risk of injury caused by sudden movements and falling objects.
Only work on the conveyor chain when the belt section is stationary.
Secure the system against unintended reactivation.
Checking and retensioning the conveyor chain
• Retension the conveyor chain 150 hrs after initial commissioning
(see Section 10.4.4 "Replacing the chain" Fig. 37 on Page 55).
• Retension the conveyor chain every 1,000 hrs (see Section 10.4.4 "Replacing the
chain" Fig. 37 on Page 55).
• Replace the conveyor chain when wear becomes visible, at the latest however
when it has increased in length by 3% (see Section 10.4.4 "Replacing the chain" on
page 51).
Lubricating the conveyor chain
The conveyor chain used in this product comes lubricated.
• Lubricate the conveyor chain before initial commissioning with Structovis GHD
(0 842 904 229), using 1–2 g oil/m of chain, then every 1,000 hrs with 2–3 g oil/m
of chain.
• Lubricate more frequently, e.g., every 500 or 200 hrs when using production
processes that include rinsing, fl uid transfer, etc. in which the lift transverse unit
chain could be washed out (see Section 10.4.4 "Replacing the chain" on page 51).
