Maintenance and repair
51/72
10.2 Inspection
Chain
Inspect the chain regularly, every 1000 h, for ease of movement, suffi cient
lubrication, correct chain tension (see page 44) and wear. Check more frequently,
e.g. every 500 h or 200 h, 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
Chain
Lubricate the conveyor chain before initial start-up and after longer downtimes,
then every 1,000 h, with Structovis GHD, 0 842 904 229. Lubricate more frequently,
e.g. every 500 h or 200 h, when using production processes that include rinsing,
fl uid transfer, etc. in which the lift transverse unit chain could be washed out.
We recommend using the LU 2 automatic lubrication unit.
Replace the conveyor chain when wear becomes visible and at the latest when it has
increased in length by 3%.
Bearings
The bearings have lifelong lubrication and are maintenance-free under normal
conditions of use.
Gear
The gear is maintenance-free.
Motor
To ensure adequate cooling of the motors, regularly remove dirt and dust deposits:
• from the surface of the motor,
• from the intake openings on the fan hood,
• from between the cooling ribs.
The cleaning intervals depend on the ambient and operating conditions.
