Rail profiling

Since the inception in 1968 in South Africa of on-track rail rectification, Lennings Rail Services has been operating and maintaining grinding machines supplied by Speno International of Geneva. Rail rectification includes all the aspects of the surface fatigue treatment, corrugation removal, profile restoration for rail/wheel contact and wheel burn removal

The URR32E-SB 32 stone grinding machine and the two RR24-M 24 stone machines are equipped with the latest technology necessary for rail reprofiling and rectification to achieve the best technical and economic benefits

The operational performance of these machines has been brought to new heights thanks to a number of state of the art innovations: Computer controlled angular positioning of the grinding units with automatic pre-selection of a wide range of patterns according to surface defects and the required transverse profile Automatic grinding load control Higher performance grinding stones Transverse profile measuring equipment for quality control and operator interface Water canons for efficient fire fighting together with passive spark deflectors Dust aspiration for maintenance and environmental reasons. Economic benefits that can be achieved are: Better track stability - extending track geometry durability Extending wheel life - improved rail/wheel contact Reducing noise levels - elimination of corrugations and surface defects Extended rail life- reduced surface fatigue and wear Reduction in tractive effort - fuel and energy savings. An RR18E-5 18 stone grinding machine is in use on the private rail industry in southern Africa. The compactness of this machine is ideally suited for short sections with severe rail surface defects
