A Load Moment Indicator (LMI) is a crane safety system designed to help operators monitor the load and lifting conditions during crane operation. It provides important information such as load capacity, actual load, boom length, boom angle, and working radius, helping operators understand the crane’s operating condition in real time.
Dynamic Equipment India’s LMI solutions are designed to support safer and more controlled lifting operations. The system provides visual and audible warnings when the crane approaches its safe operating limits, helping operators take corrective action and reduce the risk of overload and unsafe lifting conditions.
Key Features & Benefits
- Real-Time Load Monitoring – Continuously monitors the crane load during lifting operations.
- Rated Capacity Display – Shows the crane’s available and used lifting capacity.
- Boom Length & Angle Monitoring – Helps operators understand the position and working condition of the boom.
- Working Radius Indication – Displays the distance between the load and the crane’s center of rotation.
- Visual & Audible Alerts – Provides warnings when operating conditions approach defined safety limits.
- Overload Protection – Helps reduce the risk of lifting beyond the crane’s safe working capacity.
- Clear Operator Display – Presents important crane information in an easy-to-read format.
- Optional Cut-Off / Lockout – Depending on crane configuration, the system can support cut-off functions to restrict unsafe crane movements.
What Does an LMI Monitor?
Depending on the crane and system configuration, an LMI can monitor and display:
| Parameter | Purpose |
|---|---|
| Load | Shows the current load being handled |
| Rated Capacity | Indicates the crane’s permitted capacity |
| Boom Length | Monitors the extended length of the boom |
| Boom Angle | Shows the current boom angle |
| Working Radius | Indicates the load’s working distance |
| Overload Condition | Alerts the operator when limits are approached or exceeded |
Why Choose Dynamic Equipment India LMI?
Dynamic Equipment India provides reliable crane monitoring solutions designed around the actual requirements of lifting equipment. Our LMI systems can be configured according to crane type, capacity, boom arrangement, and required monitoring parameters.
We focus on accurate monitoring, clear information, reliable operation, and practical integration, helping operators work with better awareness of crane conditions.
Applications
LMI systems can be used across various crane and lifting applications, including:
- Mobile Cranes
- Tower Cranes
- Crawler Cranes
- Hydraulic Cranes
- Construction & Infrastructure

Safety & Protection
An LMI provides operators with continuous information about the crane’s operating condition. When monitored parameters approach configured limits, the system can generate visual and audible warnings.
For compatible crane configurations, cut-off or lockout functions can also be integrated to help restrict selected crane movements when unsafe conditions occur.
Important: The exact monitoring parameters, alarm limits, and cut-off functions depend on the crane model, configuration, sensors, and system setup.
