Design & Construction
Any vacuum lifting device placed on the market in the EU since 1992 must satisfy the relevant essential safety requirements (ESRs) of the Machinery Directive 98/37/EC as amended, implemented in the UK by the Supply of Machinery (Safety) Regulations 1992.
European standards BS EN 13155:2003 + A2 2009 - Cranes. Safety. Non-fixed load lifting attachments & BS EN 14238:2004 Cranes - Manually controlled load manipulating devices. have been introduced to give guidance to manufacturers for compliance with the Machinery Directive.
Kilner Vacuumation have for many years understood the need for such a standard; our experience over the last 50+ years has resulted in a design philosophy in which safety always comes first. The new standard lays out many requirements that have been `standard specification' on our products for many years and since January 2004 all our products have been designed to meet or exceed the requirments of the above standards.
Key Design Requirements - BS EN 13155:2003 + A2 2009
- Two action control of the vacuum release function.
- Adhesion force must be a minimum of twice the S.W.L at the lower end of the working vacuum range & taking into account frictional & dynamic conditions.
- Devices intended for use on construction sites must have a dual circuit vacuum system. Each circuit must comply with the rule above.
- Proof load testing at twice the S.W.L.
Inspection & Testing
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) states that all lifting equipment used for lifting persons or an accessory for lifting shall be thoroughly examined at least every 6 months.
