BlokCam is a wireless camera system that can be quickly and easily deployed to the hook block or boom tip of a crane and allows the operator to see and hear the load and surroundings, giving an unobstructed, live, audio-visual feed of the critical areas that working in the blind would never allow.
The BlokAlert system is a warning system attached to the hook block. When activated, the consistent proximity between the hook block and the load enhances the efficiency of the warning system and draws attention to the hazard, not away from it.
The sensor captures the audio/visual feed and sends it to the transmitter. The signal is then transmitted to a repeater on the jib, boom, or cab.
The battery powers both the transmitter and the sensor. Each component attaches magnetically and can be mounted on the block, including between the cheek plates and on the boom tip. Relevant systems include the X3L Camera System and the M3L Camera System.
The repeater receives the wireless signal from the transmitter and is relayed back to a monitor in the cab. The repeater position and configuration is dependent on the type of crane, type of jib/boom and length of jib/boom.
The live audio-visual feed is then processed and displayed on the screen positioned inside the cab, allowing the operator to see and hear live footage of everything below the camera.
