27.8.1 Installation
Installation will vary from simply hanging a portable self priming type of vacuum lifter from a correctly sized, free to articulate crane hook, to a more complex operation involving an electrically powered or venture type of vacuum lifter.
Portable vacuum lifters are relatively rare and most vacuum lifters will be permanently installed as an integral part of a lifting appliance. For all types IT IS ESSENTIAL to ensure that the vacuum lifter is only installed on the equipment and for the lifting operations for which it has been chosen. In addition:
27.8.1.1 Self priming or actuating type
Take account of the self weight of the vacuum lifter – it can be significant.
Ensure that the lifting eye of the vacuum lifter correctly engages with the seat of the lifting machine hook and articulates freely with it so that the vacuum lifter hangs level and presents itself to the load such that the surface of the load is parallel to the face of the lifter’s vacuum pads. If necessary use an intermediate lifting accessory such as a shackle.
Ensure that the lifting pads of the vacuum lifter are presented to the load in the correct position relative to the load’s centre of gravity.
Take account of the shape of the load and match the vacuum pads to the load.
Where manual manipulation of the suspended load is required, the risks to the operator or other persons must be considered.
27.8.1.2 Electrically powered types
As for self priming types point 1 – 5 inclusive.
Ensure availability of electrical supply (either battery or mains).
Ensure that the appropriate electrical safety tests are carried out.
27.8.1.3 Venturi types
As for self priming types point 1 – 5 inclusive.
Ensure availability of compressed air supply.
