BlokAlert wireless crane block proximity alarm

1. What is BlokAlert? BlokAlert is a wireless, audio-visual warning system that can be quickly and easily deployed to the hook block of a crane.

2. How does it work? When activated by the lifting crew, the BlokAlert receiver gives out a recognizable audio-visual signal that can be seen and heard by site personnel in proximity to the hook block or load. This forewarns the workforce to the position and movements of the hook block, increases awareness, and reduces the risk of being struck by the crane’s hook block, lifting accessories, or load.

3. Why would I use BlokAlert versus another system or more traditional method? In many work sites the distance between the horn, often located near the operator’s cab, and the load, is inconsistent and does not efficiently warn site personnel to the position of the hook block or load. The same can be said for airhorns or whistles when used by riggers. In both scenarios, the attention of the work force is diverted to where the sound is coming from, as opposed to the hazard.

4. What’s in the box?

• 1 x BlokAlert receiver
• 1 x Hard shell transport case
• 2 x Operator telemetry remotes

5. Do you stock other BlokCam products, beyond the BlokAlert? Yes:

• The X2 was the industry’s first fully modular system compatible with tower cranes.
• The M3 is designed to be easy and quick to install to mobile, crawler, or overhead gantry cranes.

6. Why would I use a crane camera when my operators have been working safely without one for years? Crosby BlokCam’s systems have delivered clear enhancement of load handling in several sectors, most notably construction and renewable energy. Many regulating authorities are looking at mandating crane camera systems, which enhance productivity and safety on all kinds of lifts and applications.
