The right choice of dredging equipment is an essential and very complex step on the silt removal job. It’s fundamental to take into account the purpose, depth of hydric body and the types of sediments to be dredged as well as the conditions of the working area, amongst other variables.
Allonda has more than 10 dredging equipment, in addition to boosters and different pumps. And, to make our dredging process even more inefficient:
- We have technologies that are added to dredges to improve the monitoring of the dredging profile;
- Include detectors and data transmitters;
- Execute shaping of the digital terrain;
- Control automatic cut;
- Engage detectors of measuring and flow of solids;

CUTTER SUCTION 50-II DREDGE
It’s important to pay attention to the hardness and plasticity of the soil when choosing the correct dredge. Harder soils, for example, are more difficult dislocate, asking for a greater cut power with the B50. Finally, plastic soils tend to cover the end-suction casing, impacting the time of the dredging process.

MONITORING OF DREDGING PROFILE
Operation: a software makes the mapping of the are to be dredged bathymetrically showing where the solid concentrations are and the leveling of the terrain.
Application: it has as its function making the mapping of the area that’s being dredged, seeking to the absolute control of the area to be dredged.
Benefits: higher efficiency on the dredging process; time optimizing in the dredging process and decreasing of operational cost through the controls of generated information; real time information of the dredging process; decreasing of dead time of the process.
DETECTORS OF DATA TRANSMISSORS
IHC dredges are composed by various detectors, which are responsible for informing important data with instant monitoring of components, giving the operator information that will be used as operational parameters.
This interface between machine and operation, through the transmission of data collected by detectors, grants the operator absolute control over the equipment and is able to get better operational results. Once the data are analyzed and treated, will result in better productive gains and operational cost decrease.
SHAPPING OF DIGITAL TERRAIN
It’s a monitoring tool of the terrain and allows the operator to have bigger controls on the depth of the cutting area. By doing the shaping of the terrain, this system shows in a detailed way the irregularities of the terrain, contributing so as that the dredged are is leveled in a homogeneous way.
CONTROL OF AUTOMATIC CUT
It has as its function integrate all generated information by the equipment and transmit them to the operator through a monitoring screen.
This generated interface between machine and man, with an ACC system, allows better operational efficiency, cost decrease, agile and precise decision making over the information.
Another point of great relevance is on the maintenance aspect, where there’s precise information of the working mechanism, allowing to have a power over the operation of the equipment making it able to foresee future fails and act before the happen.
MEASUREMENT OF SOLID OUTFLOW DETECTORS
The outflow measurer detector instantaneously indicates the volume of the material that’s being pumped. This parameter is of fundamental importance for operational references, in addition to having momentaneous information of the volume of the dredged material. Which contributes with the operational decision making to search for bigger operational income.
The outflow measurer detector will indicate the real quantity of solids that’s being pumped, bringing new, instant information about the real volume of the material that’s being pumped.
Benefits of the process: having the momentaneous information of the quantity of pumped solids, not having the necessity of making material essays during the pumping process, operational cost decrease and contribution for operational decision making.
