Depending on requirements, TAKRAF Group designs and supplies various wagon unloading solutions, including rotary tipplers, crescent-type tipplers and side-unloading tipplers. Our systems are able to unload a train even when there are wagons of different sizes. We also design and supply ancillary equipment such as train positioners, rail clamps, shifting platforms and compressor wagons to unload trains without a coupled locomotive.
TAKRAF performs dynamic train simulations with its own developed software, re-calibrated by site readings. Software-based simulation enables us to determine indexer arm forces and mitigate peek shockwave amplitudes by adjusting speed profiles during project execution.
Using our extensive expertise, we consult with clients in advance regarding preferred rail gradients and curvatures, as well as indexer speed profile adjustments during train unloading, to optimize average system throughput.
Multiple tippler arrangements (tandem/triple/quadruple) are achieved by combining single tippler units for a high degree of component standardization and to attain system redundancy requirements. In such a multiple tippler array, a train can still be unloaded when a single tippler unit is out of service.
A wide range of standardized features can be added to the basic machine to suit client needs.
TAKRAF has extensive experience in structural stress analysis for highly stressed components to optimize equipment weight and to avoid material fatigue before end of design life. Targeted stress annealing during fabrication of highly stressed structures supports the longevity of the system.
The computation of the moving center of gravity during a tippler dump cycle provides optimal pre-balancing of the turning tippler cage. A balanced system leads to efficient drive power demand.
Indexer and tippler drive braking loads can be converted into generated energy by AFE-type (Active Front End) VFDs, which can be fed back into the client’s power grid.
