Intelligent Power-Analysis
Weighing & Safety
for Container Cranes
Pioneer of motor power-signal–based load sensing. Since first launching the power-data hoist weighing sensor in 2011, Celijia has built more than two decades of R&D into intelligent power-analysis weighing, anti-mislifting and predictive-diagnostic systems — now deployed on 2,000+ STS, RTG and RMG cranes at major container terminals worldwide.

Engineered for the realities of port operations
Two decades of motor power-signal R&D — originator of the category since 2011 — translated into systems you can install in the equipment room and forget about.
Sensor-Free Reliability
Calculates lifting load directly from motor electrical parameters — eliminates zero-drift, false alarms and routine calibration.
Sub-second Protection
Overload alarm response under 0.6 s and 20,000 samples/s sampling rate — meaningfully faster than VFD-torque or sensor-based methods.
AI-driven Anti-Mislifting
CNN waveform recognition catches twistlock-not-disengaged events with a 0% missed-alarm rate, validated across hundreds of installations.
12+ Year Service Life
Solid-state architecture mounted in the equipment room — no field-exposed sensors. 5 years calibration-free, > 12 years service life.
Solutions across the lifting cycle
From overload protection to anti-mislifting and predictive diagnostics — fully compatible with STS, RTG, RMG and mobile harbour cranes.
Intelligent Power-Analysis Sensor
The core of every Celijia system. A sensor-free weighing technology that derives lifting load directly from the hoisting motor's current and voltage signals — no mechanical strain element, no calibration drift, no field-exposed hardware.
