Load Moment Indicator (LMI) for Mobile Crane
1. Display
Load Moment Indicator (LMI),
also known as Rated Capacity Indicators (RCI), or a Safe Load Indicator (SLI) or an
Automatic Safe Load Indicator (ASLI) is a device which is installed on Lattice or Crawler
cranes to alert the operator if the lift is exceeding the safe operating range of the crane.
In some cases, the device will physically lock the equipment in circumstances it determines to
be unsafe. LMI systems are usually composed of a microprocessor connected to various sensors on
the crane itself. The LMI measures the angle and extension of the boom along with the load weight
and compares this with the manufacturer's specifications to determine if the lift is safe.
A safe
load indicator has the capability of detecting the angle, weight of load lifted, and ground radius
of any lifting device. It controls the lifting equipment to the level that it tries to keep the crane
functioning as per the manufacturer's suggested safety charts.
The crane is fitted with multiple sensors, for each of the measured parameters, which are then further
displayed in the operator's cabin for his benefit
Safe load indicators come for different types of cranes including crawler cranes, hydraulic cranes, port cranes, rail cranes, tower cranes, telescopic cranes, and boom cranes. Safe load indicators help crane operators by providing critical information that the operator requires to make a decision regarding the lifting of the weight.
Crane Safe Load Indicators have multiple alert options such as
1. To alert for maximum angle exceeded - this helps the crane operator whether the load is in danger of falling or not to go beyond that angle.
2. To alert for maximum load - of course, this is the basic purpose of the crane safe load indicators.
3. To alert for maximum radium exceeded - so the crane's operator knows that the load might be at risk of falling if it is raised any further.
4. To alert for maximum wind speed exceeded - so the crane operator can make appropriate speed and height adjustments.
There are many advantages of using safe load indicator - from cost reductions and better control to safety.

How Does a Load Moment Indicator Alarm Working?
Sound and light alarm function: when the crane boom work amplitude limit close to work, when lifting
load and torque device close to the permitted load limit, LMI system issued a warning of slow beeping sound.
Warning lights flashing slowly torque system.
When jib frame work scope to work limit, when the lifting load
and torque reaches equipment when the permitted load limit moment send urgent alarm beeping sound.
Shortness of torque system alarm indicating red light flashing.
• The LMI is an operational aid that warns a
crane operator of approaching overload conditions and over hoist conditions that could cause damage to equipment
and personnel.
• The device is not, and shall not, be a substitute for good operator judgment, experience and use of accepted safe crane operating procedures.
•
The responsibility for the safe crane operation shall remain with the crane operator who shall ensure that all
warnings and instructions supplied are fully understood and observed.
• Prior to operating the crane,
the operator must carefully and thoroughly read and understand the information in this manual to ensure
that he knows the operation and limitations of indicator and crane.
• Proper functioning depends upon proper
daily inspection and observance of the operating instructions set forth in the operators manual.
What's The Load Moment Indicator Protection function ?
Control output function: when boom amplitude limit close to work,
work when lifting load and torque device close to the permitted load limit, the system output torque control
signal to stop the crane continue to continue to run in the direction of risk, allow crane moves in the
direction of security.
• can keep the crane safe from accidents
• help the operator to verify all the necessary parameters to work in the right and practical way
