PALTRONIC – Smart Crane Control
PALTRONIC control electronics continuously monitor crane load, position, and stability in real time. Sensors send data to the system, which automatically activates safety, assistance, and performance functions when needed. This results in smoother movements, overload protection, improved stability, and easier operation—allowing the operator to focus fully on safe, precise load handling.
Optional Features
Radio Remote Control – Full Control
Radio remote control system operates the crane safely and efficiently from a distance. Operator commands are transmitted wirelessly delivering precise hydraulic movements. This enables clear visibility of the load, one-person operation, and allows work outside danger zones. Adjustable controls, speed settings, and built-in safety shutoffs improve comfort, accuracy, and overall job site safety.
HPSC – Smart Stability, More Reach
High Performance Stability Control (HPSC) continuously calculates crane stability based on the real position of the stabilizers. The system automatically adjusts the permitted working range for each setup situation, maximizing the lifting capacity even when space is limited. This improves safety, increases usable reach, and gives the operator clear, reliable guidance during crane operation.
