Crane Monitoring System

Crane fleets need continuous visibility into load, tilt, and operating conditions. Without it, breaches and mechanical issues may remain undetected until an incident occurs on site. Melqart Systems delivers telemetry for every crane: real-time load, tilt, and operational data from sensor to dashboard, with tamper-proof compliance logs that satisfy EN 13000 and BS 7121 requirements.

Operational Visibility Gap

Crane fleets need continuous visibility before incidents occur.

Mobile and tower cranes operate in environments where real-time monitoring is critical, but many fleets still rely on manual inspection, periodic maintenance, and post-incident analysis. When a crane is overloaded, operated outside rated parameters, or affected by a mechanical issue, the first signal is often a failure. A single incident can mean equipment damage, project delays, insurance claims, and regulatory consequences. Melqart Systems connects the crane's control bus, sensors, and operational data to a unified monitoring platform so operators and managers can see operating conditions in real time, from anywhere.

Real-time overload protection

Continuous load and tilt monitoring with configurable alarm thresholds, detecting breaches before they become incidents.

02

Remote fleet visibility

Operational status, location, and health across your entire crane fleet from one dashboard.

03

Compliance-ready data logging

Tamper-proof operational records that satisfy EN 13000, BS 7121, and insurer audit requirements.

04

Predictive maintenance signals

Cycle counts, utilization patterns, and anomaly detection from actual usage data, not calendar intervals.

The challenge

Where current approaches fall short

01

Safety breaches detected only after an incident

Without a live view of load conditions, tilt angles, and operating hours, threshold breaches can remain undetected until an incident occurs. The resulting cost can include equipment damage, project delays, and insurance claims.

02

Calendar-based maintenance misses actual wear

Without continuous monitoring, maintenance is scheduled on fixed intervals rather than actual usage data. This can cause premature service on low-utilization cranes and costly breakdowns on equipment with the highest workload.

03

Manual logbooks cannot reliably satisfy certification or insurance audits

EN 13000, BS 7121, and insurance audits require complete, tamper-proof operational records. Manual logbooks are incomplete, error-prone, and difficult to audit, creating liability exposure after an incident.

FAQ

Frequently asked questions

01What does a crane monitoring system measure?

Load, tilt and operating conditions in real time, read from load and tilt sensors and the crane bus (CAN/J1939). Telemetry runs continuously at 1 Hz, with higher-resolution burst logging during alarm conditions.

02Can crane monitoring be retrofitted on existing cranes?

Yes. The system supports CAN/J1939, Modbus RTU/TCP, analog 4-20 mA and RS485, and is compatible with major crane OEM bus systems including Liebherr, Manitowoc and Tadano architectures. Mobile and tower crane fleets can be retrofitted without replacing the crane controls.

03Is this a telemetry retrofit or a mechanical crane conversion?

A telemetry retrofit. Melqart adds an edge gateway and sensors to an existing crane to read load, tilt and the crane bus (CAN/J1939), without replacing the crane controls. It does not change the crane's mechanics or structure, and Melqart does not carry out mechanical crane conversions. On one crane fleet retrofit, the operator reported a lift-event capture rate of about 99.3% and 0% frame loss within a 24-hour no-service window.

04What results has a crane fleet retrofit delivered?

On a crane fleet retrofit, the operator reported a lift-event capture rate of about 99.3% across the fleet, and 0% frame loss under 2G or no-service conditions within a 24-hour window, thanks to local buffering and resume-on-reconnect.

05Does the system keep compliance logs for audits?

Yes. Logs are tamper-proof and structured for EN 13000, BS 7121 and insurance audit requirements. They are stored on a local SD buffer and resynchronized to the cloud automatically after connectivity gaps.

06Which gateway hardware is used on the crane?

A telematics gateway built for harsh outdoor environments, with industrial-grade components. It connects over LTE/4G with a multi-carrier SIM and can fall back to WiFi or Ethernet.
