Basic Elements of a Crane Replacement Anti Two Block System
- Display or Receiver Unit - is mounted in the cab or by the operator controls and is designed to monitor the radio signal for the boom tip located anti two block switch. Generally this display is also able to generate an electrical signal output used to activate pre installed lockout function. The display/receiver comes standard for 12V or 24V negative body machines. For machines requiring non-standard electrical systems, adapting relays or different installation procedures might be needed as further detailed.
- Radio Anti Two Block Switch - to be installed at the tip of the boom and/or jib. This switch actually detects the two block condition via use of a weight and chain and relay switch and instantaneous transmits this information to the control mounted display.
- Weight & Chain - this is the part of the system that hangs down along the load line and holds the anti two block switching mechanism under pressure. If the hook block moves too close and lifts this weight the switching mechanism in the A2B switch is triggered. Please note that you will need to reuse an old weight and chain or order a new one separately.
