Growing concerns are being reported about crane breakdowns connected with the use of AdBlue. ESTA, the European association for abnormal load movers and mobile crane operators, is seeking information from its members in order to address the matter.
AdBlue is an engine additive that is designed to reduce noxious emissions by converting nitrogen oxide in the exhaust gas of diesel engines into nitrogen and water. It seems, however, to be far from problem-free. Crane rental companies around Europe are reporting growing issues with the system, with some saying that almost one third of all on-road breakdowns seem to be AdBlue related. Contamination of the system leading to engine stoppage, and crystallization of the additive under cold conditions, seem to be just two of the issues involved.
A key concern, says ESTA, is that if the AdBlue system malfunctions – perhaps because the engine is too cold – then the crane’s engine can lose power or even shut down, with potentially dangerous consequences. Reports suggest that similar problems can face SPMT operators, a particular concern during load outs.
“As a first step, we decided to gather information,” says ESTA. “We will then consult with the members of the European Regulations Workgroup and decide on the next steps.”
In order to allow members to send in information about problems with the use of AdBlue in mobile cranes and SPMTs, ESTA have produced an enquiry form that crane operators and member companies are urgently requested to respond to. It is available online here.
“The enquiry will only take a few minutes to complete”, says ESTA, “and your responses will help us in making our case with the engine manufacturers.
