1. Display
Load moment indicator(also called as"crane computer" or "safe load indicator") can be in form of LCD dynamic graphics and comprehensive display the various parameters in the process of work. As the main hook load, auxiliary hook load,boom Angle, length, working radius, etc.;
Alarm function
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, torque 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.
Torque 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.

WTAU brand WTL-A700 LMI system it's a kind of Crane safety protection device , function as belows: 1)Alarm, in case of over load 2)Stop instantly in case of over load 3)Show Live Weight while in operation 4)Prevent overload 5)Crane Movement Control 6)Allows user to collect data in .txt format 7)Increase crane working life and life cycle The Safe load indicator (SLI) has been designed to provide safety of the crane operation, with a continuous display of all the essential information needed to enable the crane to be used within its design parameters. SLIs have sensors to measure Load, Angle (from horizontal 0 to vertical 90 degree) & boom length. It has a 8 inch color touched LCD display for clear visibility, Overload alarm /Cut-off system, LED for overload, over hoist & Bypass on unsafe condition. WTAU WTL-A700 lmi function: load moment indication systems (LMI) help to prevent the operator from lifting excessive loads what could cause equipment collapse or tip over. Loads calculated by the LMI are verified against load charts. If a load exceeds the limit indicated in the chart, safety-related functions are activated and a cut-off is triggered. Anytime a load is lifted, the potential for overload is present. Accurate measurement of the load is critical to preventing dangerous overloads.

WTL-A220 Load Moment Indicator is a new type of smart weigh overload protector, which measures the changes of the weight of the loaded goods by a preset weight sensor and displays the actual load instantly on the display instrument. When the load reaches the given point of rated load, the acousto-optic alarm of the hoisting weight limiter will be triggered, with the switching value output displayed. The whole system is composed of sensor, connecting cable, microcomputer host and so on. The device is designed and manufactured in accordance with requirements of GB 12602-2009 Lifting Machinery Overload Protection Devices and GB / T 3811-2008 Crane Design Specification. With reasonable layout, easy installation, simple operation, WTLA220 Load Moment Indicator works well with high accuracy and other advantages Weight Measurement Range: 0T~400T.
