  • Page 4: General Information

    DS 350 / 1334 GENERAL INFORMATION The PAT Rated Capacity Limiter (RCL) DS 350 has been designed to provide the crane operator with the essential information required to operate the machine within its design parameters. Using different sensing devices, the Rated Capacity Limiter monitors various crane functions and provides the operator with a continuous reading of the crane’s capacity.

  • Page 5: System Description

    System Description SYSTEM DESCRIPTION The PAT Rated Capacity Limiter DS 350 consists of a central microprocessor unit, operating console, angle sensor, line riders, and anti-two block switches. The system operates on the principle of reference/real comparison. The real value, resulting from the load measurement is compared with the reference data, stored in the central processor memory and evaluated in the microprocessor.
