LMI Systems for Tower Crane

Product overview

LMI Load Movemet Indicator systems for tower crane

Monad load moment indicator (LMI) is suitable for all modelsof tower crane, making use of special sensors to provide 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 load increase, the crane rating, and the actual hoisting capacity of the tower crane.

Monad LMI technology gives the crane operator a continuous read-out of the boom length, boom angle, and the radius and an actual load weight.

Features

1. load cell Tension meter

This is a 3 pulley Sensor with clevis pin type load cell which is usually fixed at a suitable location along the hoist rope of the boom. In some cases it can be mounted through swing arm

1. Digital Controller

   1. Industrial grade dual core microcontroller based 2x16x2 line LCD display indicator with all fault indicating LED. System have ample capacity for data storage for multiple number of load charts, calibration etc.

   2. Display Parameters

   3. # Hook Height # Hook Radius # Safe load & lifted Load # Wind Speed # Slewing Angle

2. Hook height/ radius sensor

   1. Instrument based on digital rotational sensor. It can measure the height and radius by measuring winding & unwinding rotation of winch drum shaft

3. Wind sensor/anemometer

   1. Available in two models : wired & wireless,

   2. With user programmable set points

1. Wide Range 1T to 100 T

2. High Accuracy

3. High Reliability

4. High Linearity

5. Rugged Construction

6. High overload limit

7. Ease of use

8. Full Microprocessor control

9. Clear & easy to read Display

10. Backlit Display

11. Two relay output for alert & cut off signal

12. Data Logging Directly to PC in xls file and Easy download in pendrive
