Overview
The Type 7869 release frame increases the Working Load Limit (WLL) of a standard RT 6-3000 or RT 6-6000 to 7,500 kg (at 4:1 safety factor) with a breaking load of 30,000 kg. The Type 7988 release frame has a WLL of 25,000 kg and breaking load of 100,000 kg.
In most cases both types of release frame can be fitted without any modification to the acoustic release itself and is easily assembled in the field.
Manufactured from high strength steel which is galvanised and powder coated, the releases offer excellent corrosion resistance for long term deployment.
Applications for which the acoustic releases have been developed include; civil engineering, offshore construction, offshore renewables, marine salvage, defence and ocean science.
