Quick Details
Description
The Load Moment Indicator (LMI)has been designed to provide the crane operator with the essential information required to enable the machine to be used within its design parameters.
Using various sensing devices, the Load Moment Indicator monitors various crane functions and provides the operator with a continuous reading of the crane’s capacity. The readings continuously change as the crane moves through the motions needed to make the lift.
The LMI provides the operator with information regarding the length and angle of the boom, tip height, working radius, rated load and the total calculated weight being lifted by the crane.
If non permitted conditions are approached, theRC-220 Load Moment Indicator will warn the operator by sounding an audible alarm, lighting a warning light and locking out those functions that may aggravate the crane’s condition.
The system operates on the principle of reference/real comparison. The actual value, resulting from the force or pressure measurement is compared with the reference data, stored in the central processor memory and evaluated in the micro processor. When limits are reached, an overload warning signal is generated at the operator’s console. At the same time, the dangerous crane movements, such as hoist up, telescope out and boom down, will be stopped.
The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and dimensions are stored in memory chips in the central processor unit. This data is the reference information used to calculate the operating conditions.
Boom length and boom angle are registered by the length/angle sensor, mounted inside the cable reel which is mounted on the boom. The boom length is measured by the cable reel cable which also serves as an electrical conductor for the anti-two-block switches.
The crane load is measured by pressure transducers attached to the piston and rod side of the lift cylinders.
