These are unusual Recovery Cranes and very effective, or are they not cranes at all but known as something else, if so I apologise for getting off the subject. https://www.youtube.com/watch?v=heWWCHduhCk |

Recovery on the cheap? Making use of what's to hand, in this case a couple of pipeline Dozers. I don't think that any consideration of a lifting plan has been thought about. They appear to be working at or past the limit of lift. |

Quite a bit of history to those Cat cranes, known as 'Sidewinders', recommended viewing here - = http://hulcher.com/railroad-contractor/ ... istory.asp = With changes In the UK rail industry (both Heavy rail, light rail and preserved) a substantial business opportunity having re-railing and recovery equipment mounted on flat bed trucks ready to be deployed at the ring of a phone. Also interesting to view the support equipment on offer. Doesn't seem a problem using these pieces of equipment under (switched offed) catenary either. = http://hulcher.com/contractor-equipment ... deboom.asp = |

Biggest problems I can see with these Sidebooms is the space required to operate. Not a great problem in the states with access to trackside, but in UK having that amount of space is rare. Movement longitudinally of an individual machine not a great problem but with 2 or more machines then variations in speed and alignment will come in to play. Using them for a Switch replacement would be a total no no. Too much risk of damage or distortion. In UK the use of PALS / PUMS and derivitives is quite common. These units are linked by Remote control and all moves are tightly controlled. It is almost impossible to get the same control using 4 Cat D8s especially for fine movements. For use on a rip out they may be of some use but I would not even consider them for any form of track reinstatement. |
