The crane is the heart of the construction site and The Crosby Group understands the value in keeping the lifting crew and al ... l site personnel safe and operational. We improve communication and overall awareness during lifting operations using advanced audio-visual technology. We manufacture high-quality, purpose-built hook mounted safety systems. - What is BlokCam? BlokCam is a wireless system that can be quickly and easily deployed to the hook block or boom tip of a crane. The sound and view from below the camera is then transmitted and received wirelessly via the antenna systems to a screen in the cab. This 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. - 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. When activated by the lifting crew, the BlokAlert receiver gives out a recognisable audio-visual signal that can be seen & heard by site personnel in proximity to the hook block or load. This forewarns the workforce to the position & movements of the hook block, increases awareness & reduces the risk of being stuck by the cranes hook block, lifting accessories or load. The Blokcam Team are proud Winners of the London Construction awards 2015 for "Health & Safety award" and Winners of the Heavies "Innovation of the year award 2016" read more
