Earthmoving machines

Bulldozers, excavators, wheel loaders, dumpers, graders, and scrapers are subject to changeable weather and heavy working conditions for many hours in a row.

Technical solutions

Technical solutions to equip these vehicles must ensure:

  • reliability of instrumentation even under the most extreme working conditions
  • high-performance sensors to guarantee vehicle and operator safety
  • precise control of main mechanical movements
  • high immunity from electromagnetic fields

Gefran solutions for earthmoving machines

Gefran offers a package of high-performance, robust, reliable sensors for the main mechanical movements of these vehicles, such as control of steering angle, hydraulic oil pressure, position of the cylinder that controls opening/closing of the vehicle’s mobile parts, steering control, and control of position of independent suspensions.

The solutions designed for these applications include potentiometric (with contact) and magnetostrictive (contactless) technologies for position control.

RK (magnetostrictive) and PMI (potentiometric) solutions provide reliable and repeatable position measurement and adapt to different cylinder types.

Model HK pressure transducers control hydraulic circuit pressure and the weight of material loaded on the shovel or dumper. For excavators, the addition of the high-precision GI inclinometer, lets you set the maximum extension of the bucket to prevent rollover.
