In tower cranes and aerial work platforms, real-time tilt sensing is critical for preventing overturning accidents and ensuring personnel safety. MIRAN inclinometers, with their vibration resistance, wide temperature range, and high protection rating, have become key components in safety control systems for these heavy-duty machines.

Core Applications
Tower Crane Boom Angle Monitoring: The boom elevation angle directly determines lifting capacity and working radius. MIRAN inclinometers are installed on the boom to measure its tilt angle in real time, feeding data back to the moment limiter or PLC to prevent overload or overturning.
Aerial Platform Auto-Leveling: During lifting, the work basket or platform must remain absolutely level. Inclinometers monitor the platform’s tilt angle in real time, working with the control system to achieve auto-leveling and ensure operator safety.
Chassis Level Monitoring: After outriggers are deployed, the chassis must be confirmed level. Inclinometers continuously monitor chassis posture and trigger alarms if the tilt exceeds safety thresholds.
Product Advantages
Designed for harsh conditions such as continuous vibration, shock, dust, and oil contamination:
Vibration & Shock Resistant: Industrial-grade MEMS sensing elements with digital filtering maintain stable measurement under vibration.
Wide Temperature Range: Operating from -40°C to +85°C with temperature compensation to minimize drift.
High Protection Rating: Zinc alloy or anodized aluminum housing with IP67 / IP68 protection.
-Multiple Output Options: 0-5V, 0-10V, 4-20mA, RS485 for easy integration with PLC and controllers.
