Liferaft Handling Crane


About product

A Liferaft Handling Crane is a type of slewing crane specifically designed for the purpose of handling liferafts on ships or offshore installations. It is considered the simplest execution of slewing cranes available for liferaft operations.

These cranes are designed to meet the requirements set by the International Convention for the Safety of Life at Sea (SOLAS) regulations and are MED-certified. This means they comply with the safety standards and regulations mandated for liferaft launching appliances.

Product Detail

These cranes are available in different sizes to accommodate various liferaft capacities. They are suitable for handling all currently available sizes of davit-launched liferafts, ranging from 12-person capacity to 39-person capacity. This ensures that the Liferaft Handling Crane can effectively handle liferafts of different sizes, providing a reliable means of deploying and recovering liferafts during emergency situations.

Liferaft Handling Crane Components

The components of a Liferaft Handling Crane include:

  • Pedestal: This is a base structure that is suitable for welding to the deck of the ship or offshore installation. It provides a stable foundation for the crane.
  • Column: The crane features a vertical column that supports the lifting and slewing mechanisms. It is designed to withstand the loads and forces exerted during liferaft handling operations. The column may have an integrated manually driven slewing gear, allowing for manual rotation of the crane.
  • Arm: The arm of the crane is typically constructed in a box shape, providing strength and rigidity. It extends horizontally from the column and serves as the main component for attaching the liferaft and performing the lifting and lowering operations.
  • Liferaft Winch: The liferaft winch is responsible for hoisting and lowering the liferaft. It may feature a centrifugal brake for controlled and safe operation. Optionally, an electric motor can be included to provide power for hoisting operations, increasing efficiency and ease of use.
  • Wire Rope: The crane is equipped with a wire rope, usually made of galvanized (anti-corrosion) non-rotating steel. The wire rope provides the necessary strength and flexibility for lifting and lowering the liferaft.
  • Automatic Release Hook: The crane is equipped with an automatic release stainless steel hook. This hook securely holds the liferaft during lifting and releases it automatically when required, ensuring a smooth and safe deployment.
  • Remote Control: The crane is typically operated using a remote control system. The remote control allows the operator to control the crane’s movements, such as starting, stopping, and controlling the lifting and slewing functions. The remote control is of the stop-go type, providing precise control over the liferaft handling operations.

Two Types Of Liferaft Handling Crane

Liferaft Handling Cranes come in two variations based on the slewing features:

  • Manually Driven Slewing Liferaft Handling Crane: This type of crane allows operators to manually control the slewing motion. By using a handwheel or similar mechanism, the crane can be rotated horizontally to achieve precise positioning of the liferaft during launching and recovery operations.
  • Electrically Driven Slewing Liferaft Handling Crane: This type of crane is equipped with an electric motor to drive the slewing motion. The electric motor enables powered rotation of the crane, eliminating the need for manual effort. This feature enhances ease of operation and facilitates smoother and more controlled movements during liferaft handling procedures.
