•
The device is placed over the product, set down, the device closes round the product and it can be lifted.

Set down on the ground again, the device opens automatically, the automatic release locks it into
position so that the device can be lifted without closing up.

Shut-down the device without lifting equipment/carrier only on even ground. The gripping arms must be
opened enough, to ensure a secure standing of the device. Otherwise there is a danger of overturning!
