2Introduction
The safety of all persons who come into contact with the HZEV depends fundamentally
on knowing how the HZEV functions. Therefore:
Read these operating instructions before using the equipment for the first time.
These operating instructions contain important information which will ensure the correct,
economical and safe operation of your HZEV.
2.1 Short description
Lift centring devices are installed in the STEIN 300 Workpiece Transport System.
In conjunction with the workpiece carrier transport system, the HZEV enables the follo-
wing:
•exact positioning of workpiece carriers (and therefore of the workpieces located on
them),
•a further lift of the WT in the Z axis
•workpiece carrier elevation and support while power transfer operations are carried
out on workpieces.
Fig. 2-1:
Lift centring device
- Components
Other advantages of these devices are that
•the belt element is not under tension while the workpiece is being processed and
•belt wear is reduced.
i Please note:
From a stroke of 250mm, the WT must additionally be centred from above in the end
position by means of suitable centring pins, as otherwise the specified centring
accuracy is not given. These centring pins are not included in the scope of delivery.

Lift centring device
- loads

STEIN300_Hubzentriereinrichtung_HZEV_03_GB.DOC / 02.2020 9
Permitted WT loads are:
•in the X axis: 0 N
•in the Y axis: 0 N
•in the Z axis: 400 N if the load is centred and under an operating pressure of 6 bar
260 N if the load is centred and under a STEIN operating pressure of 4 bar and
•M=10 Nm if the load is not centred
•No transverse forces are permitted
i Unauthorised interventions, alterations or repairs carried out on the lift centring device
invalidate the warranty.
STEIN
Automation accepts no liability for any damage caused by unauthorised
interventions, modifications or repairs.
3.3 Residual danger
The lift centring device with extended stroke is manufactured using state-of-the-art tech-
nology and to recognised safety standards. Nevertheless their use can lead to dangerous
situations for users or third parties or to impairments of the system and other material
assets.
If used improperly, the following injuries can result:
•Crushing may occur due to dimensions not being observed and specified pressures
being changed.
