New generation of load moment indicator is  suitable for all models of tower crane, making  use of special sensors to provide the tower crane operator with actual and correct crane working  state.
It indicates the moment of force applied on  the crane, the hook amplitude as the height  of the load increase, the crane rating, and  the actual hoisting capacity of the tower  crane. In case the load reached 90 percent  of crane rating at a particular moment, it will provide  an early warning to the crane operator through a slow  blinking red light.
	When the load( along with the hook amplitude)  reached 105 percent, the load moment indicator  will automatically trigger an alarm and will stop  the lifting gear from lifting the load upward.

RC LMI applies to any model of tower cranes, using special sensor, providing the operator with actual and correct working state of tower cranes as follows through auto lighting LCD: Rated load, actual load, radius, hook height and moment percentage etc. We can set up the program according to the clients' requirements.

Load Moment Indicator Feature:
1. Control panel using industrial computer.
2. High-precision detection, error<± 3%.
3. Full-sealing cabinet, strong anti-interference.
4. Indicated by figure and picture, clear and concise.
5. LMI can be adjusted according to surrounding environment, like brightness and temperature.
6. Simple operation.
7. Applying to working under severe environment.
8. Simple and easy installation.

Working temperature: -40 degree--+80 degree.
Working humidity: ≤ 95%/25 degree.
Combined error: <1%.
Power supply: AC220V can be special made according to clients' requirement.

Signal lamp&buzzer: When the torque frame is yellow, it is pre-alarm with buzzer's discontinuous response, when the torque is red, it is alarm with buzzer's continuous response.
