LLB

Load limiter for baskets

The LLB system is designed to determine the maximum permissible load in the basket of an aerial platform.
The system consists of an electronic board equipped with a microprocessor and load cell sensors, each with a redundant signal, installed under the basket supporting structure. The system complies with EN ISO 13849-1 and EN ISO 13849-2 PL d.
