Technical Description
The T-ISS PX01R is the highest SWL release hook in the T-ISS liferaft range, with a 35 kN capacity, designed for larger davit-launched liferaft systems. Its off-load mechanism ensures that release, whether automatic or manual, only occurs when the raft is already floating and no load is applied, eliminating the risk of accidental opening during lowering. In automatic mode, the hook opens upon contact of the raft with the water; in manual mode, the crew releases it directly as the situation requires. Manufactured from stainless steel 316 and Duplex steel, the PX01R offers superior corrosion resistance in high-salinity and high-humidity environments, making it ideal for merchant vessels, offshore platforms, and vessels operating in harsh conditions. As of January 2026, the PX01R is approved exclusively for liferafts in compliance with the latest SOLAS updates, replacing the previous code 090171 with improved technical specifications. Eurosul is the official distributor and authorized service station for T-ISS hooks in Brazil, providing specialized technical support, periodic inspection, and component replacement as required by the standard every 5 years, essential to maintain compliance with classification society surveys and maritime authority inspections.
