Load limit device card for Demag AC 100

The load limit device card, part number 00028212 A 702, serves as an electronic control unit within the safety architecture of the crane. It continuously processes input data from weight, angle, and boom length sensors to compare the current load against the maximum permitted capacity for the specific crane configuration. By interpreting these inputs, the card manages the load moment indicator system to alert the operator and trigger automatic cut-out functions if the crane approaches or exceeds its rated capacity. This prevents hazardous overloads during lifting operations.

This component is engineered for the Demag AC 100 all-terrain crane. It integrates with the crane's onboard computer to ensure that all lifting activities remain within the established design limits. The card contains the necessary circuitry and software to process sensor data accurately under the operational conditions typical of heavy lifting equipment. Regular verification and calibration of this electronic module are required to maintain the integrity of the crane's safety systems.

Load limit device cards of this type act as the primary interface between the crane sensors and the operator's display. They ensure that the machine's operational envelope is strictly enforced, which is necessary for the protection of the crane structure and the safety of site personnel during complex rigging and hoisting tasks.
