Load Moment Indicator (which also called "Safe load Indicator"(SLI) or "Crane computer") is a device which is installed on mobile, crawler, tower, gantry or portal crane. It alert the operator if the lift is exceeding the safe operating range. In some cases, the device will physically lock out the machinery in circumstances which considered to be unsafe. The crane LMI systems are usually composed of a main console connected to various sensors on the crane itself.


The Safe Load Indicator SLI can measures the angle and extension of the crane boom along with the load weight and compares it with the manufacturer's specifications to determine if the lift is safe. A safe load indicator has the capability of detecting the working radius of the lifting device as well. It controls the lifting equipment to function as per the manufacturer's suggested safe load charts. Each of the measured parameters will then further be displayed in the operator's cabin.


BTW, as the crane types differs, thus different components will be offered respondently. Such as Mobile telescopic crane will ask for length angle sensors, but crawler lattice crane will not.  The tower crane will require the slewing limit switch and lever indicator, etc.  For offshore and marine cranes, as the hazardous enviroment, the safety system will also require camera system beside the Load moment indicator(LMI). 


Weite Technologies Co., Ltd has 17-year exeperience in both onshore and offshore crane safety protections. Its modernest WTL-A700 Safe Load Indicator can be applied for different cranes. If you have any enquires, pls turn to the sales engineer and check the technical parameters first.
