iSTACKER STACKING ASSISTANT

STACKING ASSISTANCE manual / auto

By monitoring crucial process values such as the Angle of Repose, the material distribution, andthe current dropping height, the system ensures that stockyard capacity is fully utilized while always adhering to the pile’s footprint. As a result, compact and clean piles are consistently maintained, leading to improved efficiency and space optimization, in both full autostackingmode and manual assistance. 

iStacker maximises use of stockyard capacities.

RADAR SENSORS

iStacker incorporates two indurad iSDR-P 3Dradar scanners, strategically mounted at the tip of the boom, with one on each side. These 360° scanning radar units are capable of sweeping ±60°, providing comprehensive coverage for precise data collection and monitoring 

iSTACKER KEY BENEFITS

STACKING ZONE HEIGHTS SA-H

zone based height measurement

  • Distance between boom tip and stockpile safely measured and controlled
  • Indipendend of luffing angle
  • Builds flat conformant profiles efficient to reclaim

optimal stacking space allocation

Guarantees constant and equal stacking height. No more irregular surface profiles

reduces environmental impact

Keeping a minimal drop height to reduce dust emmissions

stacking zone heights on left and right of boom

boom to pile distances

BOOM2PILE DISTANCES SA-BPD

minimum distance calculation

  • Orthogonal zones between boom and pile for different distances
  • Returned is always the distance to the nearest target

reduces maintenance costs

Prevents the boom from touching the pile

no blind spots

Contour based calculation works from iStockpile model

ANGLE OF REPOSE SA-AOR

model based evaluation of pile slopes

  • Individual observation of pile’s front and backside. 

  • Orthogonal measurement, independent of slew angle

  • Filtering for correctly aligned pile faces in current direction
  • Slope histogram analysis

max utilization of yard capacity

Footprint adjustment by online Angle of Repose

online angle of repose

"Peak" detection for best estimation of AOR

iBelt volume scanning

STACKING PATTERN /

LAYER CONTROL

iBelt Predictive Volume Flow in m³/s (replacing t/hr)

3D pile scanning is not real time and has occlusions in active stacking sector. Pile shape consistent with material changes (density, granulometry,  humidity, ..)

accurate pile build up

by using m³/s instead of t/h as control value

controlled layer thickness

by controlling Long Travel speed

STACKING METHODS

all common stacking methods supported

iStacker Face-Up returns the ideal starting point for the stacking process on empty stockyards or partially reclaimed piles

full support of production processes

different stacking methods for changing production requirements

operator independent

same high quality results on every pile, with every method, every time
