CRS’s  customized containerized coal loading systems regularly see load rates >1,250tph (tonnes per hour) per crane. When you multiply this by two when using two STS cranes, very respectable (>1,250tph) loading rates can be achieved, at a minimal investment, using CRS’s Rotainers®, Rotatable Spreader and its heavy duty, high cycle, Coaltainer®.
 
To achieve efficient load rates, the most effective set-up is with the CRS Rotainer Eurospec 38 combined with its fully automated, N.S.E.W. rotating spreader; this allows the prefect placement of each load in the ship’s hold.
 
This, in turn, dramatically reduces the need to long travel the cranes and reduces final trimming and ballast requirements.
 
The 360°, longitudinal rotation of the rotation head frame is controlled by pulse inputs by the operator’s joy stick. The operator pushes the button once for 90° rotation, twice for 180° rotation and so on. Once the load is discharged and the Rotainer® is on the return leg of the cycle, the spreader is programmed to automatically return to zero.
 
To maintain an efficient feed to the crane, generally six to eight containers per crane will be required if a tandem, Mafi-style tug and trailer combination is used.
 
 
 
Some of the differences between a generic style 2,900mm high cube container and CRS’s Coaltainer high cycle rotatable container are:
 
  • 38,400kg as standard gross weight v with a 42,000kg gross weight as an option. A 42-tonne gross container weight works with CRS’s newly developed 2025 Rotainer® Eurospec MH42, the Rolls-Royce of container rotators.
  • CRS’s unique, patented industry-v proven ‘whale bone’ rib design provides for full 360° rotation without the need for side supports. The rib system allows for a strong, highly flexible, heavy-duty container with the lowest cost-per-tonne of payload.
  • CRS specially engineered, high v strength twist lock pockets. Standard, cast twist corner pockets, on high cycle, shed-to-ship application, wear quickly and therefore rapidly lose design integrity — after all, they were originally designed for general container usage, not 360° operation, with load rates >32,000kg/hour up to six to ten times per hour.


CRS has one of the most versatile ranges of 2,900mm-high cube rotatable containers such as:
  • Coaltainer® 2,900mm for v approximately 35 tonnes.
  • Scraptainer® 2,900mm extra heavy v duty for arduous scrap metal applications.
  • Graintainer® for food and grain v products for 35m3.
  • Multibulker® 2,900mm, rotatable v container with large rear door and lid hatches.
  • Wastetainer® 2,900mm in 20ft and v 40ft versions for waste and refuse
  • Chiptainer® 40ft for woodchips, the v world’s largest rotatable container
  • Maxitainer® wide bodied 45m3 and v 55m3 for wood chips and wood pellets.
