When a freighter is moored at
dockside, downtime and delays are very expensive. A radio remote control system based on
Series 8-K or Series 10-K technology can bring greater precision and speed to handling
such bulk cargos as coal, grain, corn starch, salt and many more.
 Typically, digitally encoded commands from the control transmitter are sent to the
receiver/decoder in the shiploader control room. Signals are verified as to proper carrier
frequency, access code, strength, data frame integrity and further security checks. Then,
commands are output to the shiploader and conveyor control system.
Radio interface to these controls determines conveyor belt speed, stepless
shiploader travel and relay action for other control points. Series 8-K provides a range
of up to 500 feet and up to 56 controls; Series 10-K will cover 200 feet with 12 to 24
controls.
Remote Radio Control Speeds Coal Loading,
Aids Precision
At one coal facility on the Great
Lakes, a radio remote control system has reduced a two-person crew to a single operator.
It has also brought loading control direct to the loading operation so that the operator
can speed up, slow down, stop and generally manipulate the system according to the loading
requirements.
Radio remote control directs two underground plow feeder trains which pull coal
from the bottom of coal storage pilers as well as a system of four conveyor belts which
carry the coal up to the shiploader. It also directs shiploader travel, shuttle, boom and
chute.
The operator can evenly distribute coal from port side to starboard side of each
hatch and neatly trims the four corners. He/she also enters hatch numbers from the
transmitter and exercises weighing routines. The result is that each hatch is loaded and
trimmed with precision, and there’s an accurate record of the loaded weight.
Grain Exports Loaded Daily With
Radio Remote Control
The 10-K radio remote control system
is now used to control the daily loading of millions of bushels of grain into ships and
barges for shipment worldwide. At one of the continent’s largest facilities, the
system controls the booms and spouts of a 4.5-million bushel storage facility.
The 24-hour operation can load a 2-million bushel capacity ship in about a day.
Ships and ocean-going barges are the main outgoing transport media, with cargos arriving
at the terminal by barge or railcars.
Before, workers had to maneuver a heavy cable and pendant control box weighing up
to 25 pounds. Visibility was severely limited and cable damage was a constant source of
downtime. In contrast, the 10-K transmitter is easy to handle, and operators can position
themselves anywhere. Control functions include ‘run/stop’, ‘in/out’
(for the boom), ‘up/down’, and 360-degree rotation.
Seven 10-K systems are used on as many loading booms and can operate
simultaneously without cross-interference, thanks to Time Multiple Sharing (TMS). Each
transmitter is battery powered with standard AA alkaline cells that provide up to 200
hours’ continuous use. Being light, the transmitters do not cause worker fatigue and
have even withstood being dropped into water.
