Technical Data

The CRICKET consists of four assemblies:

• the protective shield,
• the detection unit,
• the wireless communication module and the battery pack
• the controller.

Detection
unit

• The primary component of the detection system.
  Size of the detection medium is configured to the size of the grapple.
• Mounted inside a specially designed “G” force compensation case that shunts the impact and multi-frequency ringing that is associated with grapple material handing conditions.
• The case is easily removed from the protective shield when the wear plate is taken off. The case resists corrosion from water and hydrocarbon products such as oil and grease.
• Inside the special case are the electronic and large volume detection assemblies, designed to withstand SEVERE repeated impacts and vibration associated with this application.
• The assemblies are mounted in such a way that they are isolated from the direct transfer of energy.
• The components of each assembly are also specially selected and manufactured to RadComm proprietary specifications with the focus on rugged MIL-SPEC designs.
• The systems electronic components include several sensors that are used to monitor the operating conditions of the grapple such as temperature, motion and impact with the scrap material.
• The unit is powered by 6Vdc from the battery pack via a shielded communication cable. The cable is protected with heavy SS mesh and mounted inside the grapple tube section where maximum protection can be maintained.

• Fits to any type of mechanical, hydraulic, electro-hydraulic grapple.
• Specially designed case construction allows the detection of low energy
  gamma sources (e.g. Am241).
• The shields high strength and wear resistance design is capable of withstanding severe impacts, commonly associated with scrap metal handling, on a continuous bases.
• Easy to install and service.
• Equipped with doors for easy access to the internal detector assembly(s).
• Detector occupies a small volume of the grapple
  - does not effect scrap handling operations.

• The battery pack measures 8” x 5” x 2 ½” (20cm x 13cm x 6cm) and incorporates a rugged steel box construction.
• The box is welded in a protected area on the tube of the grapple center section.
• A small ½” (13mm) hole is drilled in the tube to allow the communication cable access to the battery pack connections.
• Battery pack includes a shock-mounted standard 6Vdc 7.2A/hr dry cell battery and wireless communication system.
• Battery powers the detection unit electronic circuits and wireless system.
• Wireless system utilizes a low powered digital non licensed frequency that
  can transmit up to 1000 ft (300m).
