Boomerang

Weighing system for excavators and industrial loaders

At its heart is a microprocessor card that ensures a calculation speed fast enough to detect the weight of the material being handled at any time and position of the machine. Its design is revolutionary, especially in its concept of space and weight: it is so compact that it never obstructs the external view, light enough not to affect the machine’s structural integrity, and so elegant that it complements the existing instrumentation in the cabin without disrupting its harmony.

Strengths

  • Freely storable weighing height
  • Weighing in any position
    Speed compensation
  • Flatness compensation
  • Accuracy ± 1 % – ± 2 % G.W. (total gross weight)

The system

Large graphic display with 16 lines of text, backlit. Information on:

  • Total Weight
  • Last Weight
  • Number of Weights
  • Goods and Customers

The toggle buttons allow the activation of the function even under extreme working conditions.

Boomerang is equipped with a quick release connector that makes it extremely easy and fast to quickly remove or transfer the instrument from one machine to another.

Thanks to Boomerang, the operator can work freely and avoid time loss, as they:

  • do not need to stop the lifting arm
  • do not need to position the drilling arm
  • do not need to weigh before rotation

Boomerang allows the weighing point to be saved at any desired height along the lifting arm’s travel.
This feature enables the operator to adapt the weighing system to the task at hand.

Boomerang

Flatness sensor

BOOMERANG checks the flatness of the carriage and compensates for the weight calculation.

The inclination of the carriage is visible directly on the display in degrees.

Boomerang

Speed compensation

Boomerang calculates the weight by compensating and displaying the bucket ‘s ascent speed on the display.

Boomerang

The Boomerang system integrates the use of angular sensors, very high precision mechanisms, which are positioned on both the drilling and lifting arm in order to control its rotation and allow the weight to be calculated at any point in the working area.

Angle sensors measure the degrees of the angle formed between the carriage and the hoist and the angle formed between the hoist and the drill.

This choice allows Boomerang to weigh up to the first quarter of the excavator’s rotation without being disturbed by centrifugal force or inertia problems due to the movement of the booms.
