    Key Applications in Shipbuilding

    Let’s examine some of the tasks within the shipbuilding industry which would not be possible without the use of hydraulic jacks.

    Lifting and Placing Hull Sections

    They lift and position the portions of the hull within the ship's frame as per the shipbuilder's design and the customer's preferments.

    Correctly Positioning Engines and Shafts

    These are quite important for the ship as they correctly position the engines, shafts and other components which can be set at either hold or slow speed.

    Main Area for Repair and Maintenance Work

    This is where shipmen do the majority of their work on the ship and other major work is the replacement of the broken parts and the slight straightening.

    Functioning and Maintenance of Cable Systems

    Cable systems are operating well if nothing major needs to be done to them and their structure is maintained.

    Explore BEMCO JACKS Hydraulics for Shipbuilding

    BEMCOJACKS is astoundingly one of the most appreciated hydraulic jack manufacturers located in India. And they do not disappoint, boasting an extensive collection of jacks suitable for shipbuilding including:

    Double Acting, Threaded Ram Hydraulic Jacks

    • These jacks assist in the lifting of ship hulls alongside other massive structural components.

    Single Acting, Span Jacks

    • These are appropriate for raising and lowering spans and decks.

    Ultra Low Height Hydraulic Jacks

    • These jacks are exclusively designed to perform lifting of segments or girders that occur in very confined vertical spaces.
    • They can come equipped with either a plain or threaded ram.

    Bar Stressing Jacks

    • Bar stressing jacks releive the stress on a bar by pulling, applying stress back into the high tensile bars.
    • These jacks are quite vital for the structural reinforcement in the shipbuilding industry.

    Stressing Jacks

    • Stressing jacks include various subcategories such as multi-strand, mono strand and pulling jacks.
    • They are used in cable and tendon tensioning works in marine structures.

    Flat Jacks

    • Unlike traditional tools, these jacks are more space efficient allowing for a better grip on aligning parts of a ship.
    • The jacks are very useful in working in constricted spaces.

    Hollow Ram Hydraulic Jacks

    • These jacks are commonly used for putting, testing, and pulling of tension during various ship maintenance activities.

    Types of Shipbuilding Hydraulic Jacks

    The shipbuilding industry requires tremendous power and highly precise machines to lift and assemble heavy and complex parts. BEMCO Jacks is a trusted name in this field that offers a complete range of hydraulic jacks specifically designed to suit different needs – be it lifting large hull sections or precisely fitting heavy propulsion systems.

    The following are some of the most popular hydraulic jacks in shipbuilding:

    1. Hydraulic Toe Jacks

    These jacks are shaped like a “T” and are designed to lift heavy objects from below. Small in size but great in strength and stability. In shipyards they are used for the initial lifting and setting of heavy parts such as engine blocks, rudder stocks and support frames. Despite being lightweight, they provide excellent balance and control.

    2. Hydraulic Lifting Jacks

    These jacks are primarily used to lift a large hull block to a set height of the waterline or shift a ship module nearer to the assembly line. BEMCO Jacks engineers were careful not to overlook capacity considerations and made certain to provide for different simultaneous jacks so the service was accomplished most efficiently. As a result, these lifting jacks have become fundamentally essential in the entire operation of modular ship construction including dry dock work as well.

    3. Synchronized Jacking Systems

    These frameworks are built specifically to assist in multiple point lifting of large structures achieving balance and even distribution of load. The two predominant areas of application of these systems is in the construction and repair of a ship’s structure. Currently the precision of these systems is of utmost importance along with not inflicting any damage to the construction component of the ship.

    4. Telescopic Hydraulic Jacks

    The pair of jacks that jointly compose a multi-stage lifting mechanism function when effortless stable high lifting is required. In height structures shipbuilding, these jacks are especially useful for lifting superstructures and changing their height during the installation, while effortlessly controlling the lift capability.

    5. Hydraulic Push-Pull Jacks

    These jacks serve a dual purpose because of their unique forward and backward mechanism, and are designed to push and pull. Such tools are indispensable and come in handy for the construction of heavy structural parts of buildings, or any element that needs to be aligned or shifted. Furthermore, in the shipyard they allow workers to easily manipulate complex sections of the hull and keel blocks, and their large mechanical installations, without the assistance of skilled labor.

    6. Compact Flat Jacks (Low-Height Jacks)

    This is the type of jack that is flat and low profile design. They are perfect for vertical working where space is limited, for example, under keel blocks of the ship and stowed away spaces within the ship. They are of a very compact size, yet capable of heavy lifting, thus assisting in leveling and alignment tasks.

    We have considered other fields of shipbuilding activities and designed BEMCO JACKS` hydraulic jacks from the finest and thoroughly tested materials. Our main foci of production include effortless lifting, precise alignment as well as support for superstructures of enormous ships. With all the hurdles related to shipping in bulk, BEMCO JACKS provides long-lasting solutions which will suit your unparalleled accuracy requirements.

    Supporting Equipment for Hydraulic Jacks

    Apart from the several plain tools that would probably be necessary, the use of hydraulic jacks is, however, the most recommended for boosting the performance of a ship to its maximum:

    Hydraulic Hand Pumps

    • Furthermore, they are very convenient to carry as power sources that can be easily taken with you anywhere you go.
    • Additionally, having a lightweight and user-friendly design, these hydraulic hand pumps can be carried by pulling to any location.

    Lifting & Swiveling Platforms

    These platforms assist in the lifting and rotating of heavy items so that they can be placed in a more manageable position and placed with ease as the workflows are simplified.

    Advantageous Uses of Shipbuilding Hydraulic Jacks

    The advantages have been attained when the ships are assumed to be on the peak of their performance through the use of hydraulic jacks:

    • Effectiveness in performing any work
    • Precision in the handling of enormous elements
    • Reduced work overload
    • Workplace hazard due to a lack or minimal occurrence of accidents.
    • There will always less cost spent and that was particularly when hydraulic jacks were used for shipbuilding.
