Telescopic Davits
Vestdavit’s TDB-Type davits are highly specialized deck head mounted davit systems, engineered for seamless launch and recovery operations from a recess or boat bay. These davits offer exceptional versatility with a Maximum Working Load (MWL) ranging from 3.600 kg to 25.000 kg, making them suitable for a wide range of vessel applications, from naval ships to offshore support vessels. These systems are built to comply with strict naval and classification society requirements, ensuring safety, durability, and operational efficiency in demanding environments. A key feature of the TDB-Type davits is their ability to be paired via a Programmable Logic Controller (PLC), allowing two systems to work in tandem and significantly increase lifting capacity. When paired, these davits can achieve a combined MWL of up to 50,000 kg, enabling them to handle larger workboats, unmanned surface vehicles (USVs), or mission-critical payloads with precision. Vestdavit’s TDB davits have been widely adopted by the United States Navy, proving their reliability in military and defense applications. To date, the largest TDB davit systems delivered by Vestdavit boast a combined MWL of 30,000 kg, showcasing the robustness and scalability of these solutions. Show more

The Vestdavit Dual TDB Series represents the pinnacle of modern heavy lift davit technology, engineered to meet the rigorous demands of naval, coast guard, offshore, and commercial maritime operations. This cutting-edge system is designed for handling exceptionally large payloads, ensuring safe and efficient launch and recovery of heavy workboats, unmanned surface vessels (USVs), and mission-critical craft in dynamic maritime environments. The system’s capability to link two TDB-series davits through an advanced Programmable Logic Controller (PLC) provides a high degree of operational control and load distribution, allowing for a Safe Working Load (SWL) of up to 50 tons. This synchronized operation enhances stability, efficiency, and safety, making it one of the most powerful davit solutions available.
A key feature of the Dual TDB Series is its PLC-driven intelligent control system, which enables seamless synchronization between two davits. The PLC ensures precise load balancing, coordinated movement, and automated control, reducing the risk of operational errors and improving overall safety. This level of automation is particularly critical when handling large and delicate payloads, where precision is essential to prevent damage and ensure smooth deployment and retrieval. The system is designed to operate reliably in high-sea states, providing consistent performance in harsh and unpredictable maritime conditions. By minimizing manual intervention, the Dual TDB Series allows for streamlined operations, significantly reducing crew workload and enhancing overall efficiency.
