Trailer Jack

About product

A Trailer Jack is a crucial piece of equipment used for securing trailers to the deck of a Ro-Ro vessel during transportation. Its primary purpose is to provide stability and prevent movement of the trailer while onboard the vessel.

The Trailer Jack is typically positioned at the front or rear of the trailer, depending on the specific configuration. It consists of a heavy-duty mechanical or hydraulic jack mechanism that can be adjusted to raise or lower the trailer as needed. This allows for proper alignment with the deck and ensures a secure connection.

Product Detail

To secure the trailer, the Trailer Jack is extended and positioned to bear the weight of the trailer’s kingpin or rear frame. It is then locked into place to prevent any shifting or sliding during transit. This helps to maintain the trailer’s position, preventing damage to the cargo and ensuring the safety of the vessel and crew.

Trailer Jacks are designed to withstand the forces and vibrations experienced during transit, providing reliable support and stability. They are essential equipment for the efficient and secure transportation of trailers on Ro-Ro vessels, minimizing the risk of accidents and damages.

The Features Of Trailer Jack

The features of a Trailer Jack designed for Ro-Ro vessels include:

  • Sturdy Construction: Trailer Jacks for Ro-Ro vessels are built with robust materials to withstand the demanding conditions of maritime transportation. They are designed to handle heavy loads and resist corrosion from exposure to saltwater and harsh environments.
  • Adjustable Height: Trailer Jacks are equipped with adjustable height mechanisms, allowing them to accommodate different trailer heights and deck configurations. This feature ensures proper alignment and a secure connection between the trailer and the vessel’s deck.
  • Locking Mechanism: Trailer Jacks feature a reliable locking mechanism to secure the jack in place once the desired height is achieved. This prevents any unintended movement or shifting of the trailer during transit, ensuring stability and safety.
  • Easy Operation: Trailer Jacks are designed for ease of use, with user-friendly controls and mechanisms. They can be operated manually or with hydraulic assistance, depending on the specific model. Smooth and efficient operation contributes to quick and hassle-free securing of the trailer.
  • Durability: Trailer Jacks are built to withstand the rigors of maritime transportation. They are engineered for durability and longevity, capable of withstanding vibrations, impacts, and heavy loads encountered during Ro-Ro vessel operations.
  • Compliance with Safety Standards: Trailer Jacks for Ro-Ro vessels are designed and manufactured to meet relevant safety standards and regulations. They undergo rigorous testing and quality control measures to ensure their reliability and adherence to industry guidelines.

The Components Of Trailer Jack

The components of a Trailer Jack typically include:

  • Hand Wheel: The hand wheel is a manual control mechanism attached to the Trailer Jack. It allows users to rotate and operate the jack, raising or lowering the trailer as needed. The hand wheel provides convenient and precise control over the height adjustment process.
  • Wooden Plate: The wooden plate is a component placed on top of the Trailer Jack. It serves as a protective surface between the jack and the trailer’s kingpin or rear frame. The wooden plate helps distribute the load evenly and prevents damage to the trailer during the securing process. It also provides added stability and reduces the risk of slippage.
  • Jack Stand: The jack stand is the main structural component of the Trailer Jack. It provides the necessary support and stability to lift and hold the weight of the trailer. The jack stand is typically made of durable materials such as steel or aluminum to withstand heavy loads and provide long-lasting performance.
  • Lifting Mechanism: The lifting mechanism is the internal mechanism within the Trailer Jack that allows for the vertical adjustment of the jack stand. It can be operated manually or with hydraulic assistance, depending on the type of Trailer Jack. The lifting mechanism ensures smooth and controlled raising or lowering of the trailer.
  • Mounting Bracket: The mounting bracket is the component that attaches the Trailer Jack to the trailer or the deck of the Ro-Ro vessel. It provides a secure connection point and allows for easy installation and removal of the jack. The mounting bracket is designed to withstand the forces and vibrations experienced during transportation.
  • Locking Mechanism: A locking mechanism is often incorporated into Trailer Jacks to secure the jack in place once the desired height is attained. This prevents any unintended movement or adjustment of the jack during transit, ensuring stability and safety.
  • Base Plate: The base plate is the bottom part of the Trailer Jack that makes contact with the ground or the deck of the vessel. It provides a stable foundation for the jack, distributing the weight and minimizing the risk of sinking into soft surfaces or slipping on smooth surfaces.
