The SIMPORTER is capable of the high unloading rates required to discharge the type of modern bulk carrier which is rapidly becoming standard for the transport of grain and other solid bulk commodities and which range in size up to as high as 150,000 tonnes dead weight (DWT).
SIMPORTERS may be built for capacities from 600 tph up to 1,500 tph.


Whereas grabs and most types of mechanical unloader can only convey in a vertical or near vertical direction, the SIMPORTER possesses exceptional flexibility to reach into a ship's hold. This results from the ability of the elevator leg to kick-in and out by up to 35 deg from the vertical, in combination with luffing and slewing motions as well as travel along quayside rails.


Not only is the capital cost of the SIMPORTER competitive when compared with other mechanical unloaders, but it offers also other assets such as:

  • Minimum energy consumption
    This is a tremendous advantage in these times of high and ever increasing energy costs. The SIMPORTER uses approximately as little as 0.25-0.30 KW/ton which is about half that of other mechanical systems.
  • Minimum Operating cost
    Only one operator is required to control all movements of the SIMPORTER, even when unloading at maximum capacity.
    Additionally, it is important to take into account its low relative weight, which leads to potential savings in the cost of the quay along which it moves.
  • Minimum maintenance cost
    Comparative figures show that the cost of maintaining the SIMPORTER is substantially less than for other mechanical unloaders of equivalent capacity. Maintenance is also easier thanks to its widely- known conveyor belt system.


  • Minimum noise
    The SIMPORTER is exceptionally quiet, virtually the only noise being from the main drive motor and air pressurising fan.
  • Minimum material degradation
    Because the material being discharged is transported between two belts moving at the same speed, it suffers virtually no degradation.
  • Dust control
    Since the feeder normally lies buried beneath the material being unloaded, which is then held sealed between two belts, dust generation is minimal and its nuisance is virtually eliminated by a dust extraction plant fitted to suppress dust generated at transfer points.
    Dust laden air passes through textile filter sleeves cleaned by reverse air jets, the collected dust returns into the main material stream.
