grapple mounted detection systems

The CRICKET GRAPPLE is the world’s leading, most rugged and highly sensitive continuous monitoring radiation detection system, allowing for close proximity scans without disrupting ongoing production processes.

Designed to meet the needs of the scrap, steel, and waste industries, the CRICKET GRAPPLE’s revolutionary, yet simple design, provides an optimum level of detection capability for low intensity radioactive sources. The level of detection capability far exceeds any conventional radiation detection system, including detection systems that are mounted on the boom of a crane, regardless of detector size.

Mounting the CRICKET in a grapple application allows direct exposure to all the material being handled, with the most common systems listed below. There are three different operating modes. Area scanning, which operates on a continuous basis, grapple load scanning and a manual search & find scan that is used to isolate suspect material.

Options include neutron detection and Thallium doped Sodium Iodide crystal technology for isotropic identification.
