New Machinery Directive

1 James Soh New Machinery Directive

2 New Machinery Directive The new machinery directive 2006/42/EC replaced the old machinery directive 98/37/EC on , and is mandatory from that date. All machinery placed on the market within the European Union from must comply with the new directive. After , the old machinery directive 98/37/EC no longer exists

3 New Machinery Directive & EN The newly revised loader crane standard EN 12999:2011 is harmonized with the new directive and offers more concrete guidance how to interpret the directive

4 New Machinery Directive The machinery directive is the law decided by the European Commission. The MD is very much in general. The loader crane standard EN is developed by CEN and with the collaboration of the crane manufacturers. All crane manufacturers in Europe have agreed on EN EN is harmonized with the machinery directive, which means that if you comply with EN 12999, you are presumed to comply with the machinery directive without the need of any further risk assessment

5 New Machinery Directive The new machinery directive is further explained in the Guide to application of the Machinery Directive 2006/42/EC that was published by the European Commission. This document contains lots of examples that help to explain the directive. The official guide can be downloaded from:

6 Definition of Machine MD 2006/42/EC In MD 2006/42/EC, article 2 (a), is written: machinery means: (same text as before) an assembly, fitted with or intended to be fitted with a drive system other than directly applied human or animal effort, consisting of linked parts or components, at least one of which moves, and which are joined together for a specific application, (new text) an assembly referred to in the first indent, missing only the components to connect it on site or to sources of energy and motion, (new text) an assembly referred to in the first and second indents, ready to be installed and able to function as it stands only if mounted on a means of transport, or installed in a building or a structure,

7 MD Definition 2006/42/EC of Machine The amended definition of machine clarifies that: A loader crane is a machine when it leaves the factory. The manufacturer s declaration of conformity remains valid if the crane is installed in accordance with the installation instructions. A new declaration of conformity needs to be issued only if the installer installs it else wise or somehow changes the crane (e.g. mounts a hoist or adds a hydraulic extension). The same applies to auxiliary stabilizer beams; they are also machines as such

8 MD New 2006/42/EC Machinery Directive There are 4 types of CE declarations that concern us: Declaration of conformity for a machine Declaration of conformity for a dangerous machine (listed in annex IV, e.g. MEWP) Declaration of conformity for interchangeable equipment Declaration of incorporation for an incomplete machine

9 New technical requirements New technology is introduced on the cranes to comply with the new directive and its interpretation in EN

10 MD New 2006/42/EC Machinery Directive Annex I, clause 1: By the iterative process of risk assessment and risk reduction referred to above, the manufacturer or his authorised representative shall: determine the limits of the machinery, which include the intended use and any reasonably foreseeable misuse thereof,... The crane must be safe not only when used as intended, but also when the crane is used incorrectly (e.g. stabilisers not fully deployed)

11 The machinery manufacturer cannot be expected to take account of all possible misuse of the machinery. However, certain kinds of misuse, whether intentional or unintentional, are predictable on the basis of experience of past use of the same type of machinery.... Such behaviour can result in a range of misuse situations, such as, for example, using a crane or a MEWP without deploying the stabilisers

12 pren Stability 12999:2007 of vehicle L P EN For cranes with a rated capacity of kg or above, or a maximum net lifting moment of Nm ( 4 tm) or above, the stability of the vehicle shall be included in the safety function of the rated capacity limiter. NOTE Stability in this case means: Deployment of every stabilizer is monitored by the rated capacity limiter and the rated capacity is reduced or the crane is stopped, if not fully deployed. This requirement does not apply to timber handling cranes

13 Stability of vehicle pren 12999:2007 The new directive came into force but the revised loader crane standard EN 12999:2011 is being nationally published only during this spring. So what about cranes manufactured in between? The basic requirement for stability supervision comes from the directive itself, and this is further clarified in the Official Guide. So the requirement for stability supervision also applies to all cranes manufactured in between. Cranes manufactured that do not have stability supervision are illegal

14 James Soh Technology Stabilizer Deployment Monitoring

15 Stability For Knuckle boom crane,outriggers are used to prevent trucks overturning when picking heavy loads. However in some circumstances, such as narrow streets, space for outriggers extension was restricted. Thus,stability monitor system can now provide the necessary safety back-up

16 Technology - hardware Slewing sensor Indicate one of the leg is not set Leg lamps Pressure sensors Extension position sensors

17 Hiab Variable Stability Limit (VSL) Lifting capacity / leg extension About 50% / 0 % Outrigger extension 0% = Fully In 100% = Fully Out

18 PK- Integrated Stability Control ( ISC ) HMF Electronic Vehicle Stability ( EVS ) ISC sets constant capacity in sectors for different stabiliser spreads

19 Technology Slewing indication: Most crane manufacture uses micro or proxy switches HIAB has a built in analogue sensor in the slewing cylinder!

20 Technology Stabiliser leg spread: Most crane manufacture uses micro or proxy switches HIAB has a built in analogue sensor in the extension cylinder!

21 Technology Stabilisers set to ground : Most crane manufacture have micro or proxy switches HIAB has pressure sensors in the stabiliser legs, which also means we have full control over the leg force, not just that the leg is set to the ground. We can also protect the stabilisers from overload!

22 pren :2007 other new requirements Stability supervision is required directly by the machinery directive, but other requirements come solely from EN : Swivelling stabiliser feet. Warnings for 90% capacity and remote control visible from all directions. Cabin warning for boom system and stabilisers (also hydraulic) not stowed for all cranes. Acknowledgment button for remote controlled stabiliser extensions

23 High boom warning Audio & Visual warning activated when boom system is over the horizontal line. Example :- Pre-set at 3 m height 4 m 3 m 2 m 1 m

24 Two machines in one! The customer can start the day with delivering building material Lorry Loader And ending the day changing light bulbs MEWP Equipped for multi purpose

25 EN280 Directive for MEWP (lorry loader) The automatic horizontal levelling function ensures that the basket is always horizontal Working in the basket is safer, easier and more comfortable Maximum allowed inclination is 5 from horizontal plane

26 To prevent these situations
