Log Screen Booms

We help to maintain power generation at some of the world’s major hydro dams such as the Kariba Dam in Zambia and the Cahora Bassa Dam in Mozambique where the amount of natural floating debris carried downstream is exceptional with serious consequences for failure to control it, and this is why they choose Bolina Booms. Our LSB600/800/1000 series of booms have a capacity of up to 100 tons break load and up to 3m draft using mesh screens that are joined to provide a seamless barrier for logs, trash etc. with full articulation of the boom’s universal joints that connect each module. The wall rails accomodate our unique self-aligning compensator design which allows the boom to smoothly follow any changes in water level regardless of the approach angle.
