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.
