INDuSTRY oppoSITIoN To NEW Eu MACHINERY REGuLATIoNS


Crane and access platform manufacturers - plus ESTA and European rental companies - have reacted with disbelief to a clause in the draft new European Machinery Regulations that requires all mobile machinery to be designed to prevent contact with overhead power lines or where the risk cannot be avoided, designed to ensure that all hazards "of an electrical nature" are prevented. Industry experts say they will


support any practical measures to improve safety, but such requirements are impossible to deliver. When finally agreed, the European Machinery Regulations will update the existing machinery directive from 2006.


This is one of the main pieces of legislation governing the harmonisation of health and safety requirements for machinery throughout the EU and is intended to promote the free movement of machinery within the single market as well as ensuring a high level of protection for workers and the public. The new disagreement concerns a


proposal hidden away in the depths of the regulations - to be precise in Annex III, Part 3, point 3.5.4. The current version of the regulations states: "When the risk of contact or electric arc with an energised overhead power line to the persons operating machinery incurred by the contact cannot be fully avoided, mobile machinery or related product shall be designed and constructed so as to prevent any electrical hazards in the event of contact with an energised power line. Klaus Meissner, chairman of CEN


TC147/WG11 - the committee responsible for the EN13000 product safety standard for mobile cranes - said: “Neither remote control of mobile cranes, their isolation, nor grounding of the equipment as a whole can prevent all

employer's responsibility under the Use of Work Equipment Directive (UWED)."


He has asked that the relevant section be deleted from the draft regulations, adding that the potential impact of such a regulation would be enormous and would affect the performance of many important tasks, such the erection or maintenance of wind power turbines and railway construction. The crane manufacturers' stance was wholeheartedly supported by Ton Klijn, the director of ESTA - the European Association of Abnormal Road Transport and Mobile Cranes. He said: "This proposal is clearly


hazards when contacting electrical power lines or arcing.


"Using the cabin as shelter would


require blocking the doors in case of contact to power lines or arcing, which in itself bears the risk that persons could not leave the cabin in case of subsequent fire." Markus Golder overall chair of


CEN/TC 147 - the safety standards committee of the European Committee for Standardisation for all types of crane - said: "It is not possible to design such a crane to prevent the risk of contact with an energised overhead power line. "There are no systems available that


can reliably detect live power lines, and therefore such cranes cannot be “constructed and equipped in such a way that all hazards of an electrical nature are prevented”, as the regulations require. Golder, who is a Professor at the Faculty


for Mechanical Engineering at Chemnitz University of Technology in Germany, continued: "As there is no technical solution available that can reduce this risk, avoiding contact with overhead power lines, it is an organisational issue and the


absurd and completely unworkable. What is disappointing is that this problem could have easily been averted if only the relevant authorities had properly consulted the industry in


the first place, something that would have saved a lot of time and trouble. "We would fully support all practical suggestions to improve safety, but as it is, such impractical proposals just bring the Commission into disrepute." Klijn agreed with Professor Golder that the way to improve safety is through effective and professional site management, common standards and high-quality training - not by making impossible demands on the equipment manufacturers and their clients. A newly drafted study by FEM - the


European Materials Handling Federation - that also looked at the debate concluded: "A potential contact to energized power lines by mobile cranes (structure of the crane, the hoist rope and/or the lifted load) cannot be avoided by inherent design of the structure due to the purpose of the equipment." The European Commission has been


asked for a comment. Read more about ESTA's work in the Europe feature starting on page 51.
