ملخص: The objective of this research work is to dévelop a microprocessor-besed system to monitor the load state and insure the safety of a mobile telescopic crane. The need for an automatic and intelligent system that determines the lifted load, in replacement to the existing design based on analog electronic, is to serve the National Crane Manufacturing Company ENP-CPG. Ain-Smara, Algeria. The conventional microprocessor-based systéme use the searching technique (look-up tables) to read the allowed load stored in memory. The drawback of such technique is that it requires a latge amount of memory space which would increase the searching time and the size of the hardware. The solution adopted in the proposed design consists of developing an equation relating the specific working configurations to the allowed load. The relation is obtained through a numerical analysis method. This approach reduces greatly the memory space, since the microprocessor computes the allowed load from the coefficients proper to each configuration. This result was checked by the data of the 1040 crane model. Which are in good agreement with the data provided by the manufacturer.
