ShipBuilding Crane Design and Function

I. Double - Hoist System

Hoist Placement

1. One hoist is positioned above the beam. This upper hoist provides the initial support and lift for the ship blocks. Its location allows for a clear view of the overall operation and better control over the vertical movement of the load.

2. The other hoist is placed below the beam. The lower hoist is designed to pass through the block spacing of the upper hoist, which is a unique and crucial aspect of this design.

Function of the Double - Hoist Setup

1. Rotation Capability: The double - hoist system enables the smooth and secure rotation of massive ship blocks around their own axis. When constructing large ships, components such as hull sections or engine parts can weigh hundreds of tons. The double - hoist mechanism allows shipbuilders to precisely position these components during the assembly process.

2. MAXTECH's Implementation: MAXTECH's ship crane, widely used in advanced shipyards, incorporates this double - hoist mechanism. Our marine cranes are equipped with high - torque motors. These motors provide the necessary power to lift and rotate the heavy ship blocks. For example, when assembling a large cruise ship hull, the high - torque motors can easily handle the weight and ensure that the blocks are rotated to the correct angle for welding and fitting.

Precision Gearing: In addition to high - torque motors, MAXTECH's ship deck cranes have precision - engineered gears. These gears work in tandem with the motors to ensure that the rotation of the ship blocks is smooth and accurate. The gears help in controlling the speed and direction of rotation, minimizing any potential errors during the construction process.

Cranes for Unloading Ships

II. Ship - to - Shore (STS) Cranes

Location and General Function

1. Sts Cranes are strategically located at ports and terminals. They act as the vital connection between the ships and the land, facilitating the transfer of containers. These cranes are designed to handle containers of various sizes, including the standard 20 - foot and 40 - foot containers, as well as larger, more specialized ones.

2. Advanced Features of MAXTECH's STS Cranes

3. Remote Operation Control Systems: MAXTECH's STS cranes are outfitted with advanced control systems that allow for remote operation. Operators can use joysticks and computer - aided controls from a control room located on the shore. This not only provides a safer working environment for the operators but also allows for more precise positioning of the crane's lifting mechanism over the containers on the ship.

4. High - Capacity Hoists: These offshore cranes are equipped with high - capacity hoists. The hoists can lift containers weighing up to several tons with ease. For instance, in a busy container port, MAXTECH's STS cranes can quickly unload large containers filled with heavy machinery or consumer goods, significantly increasing the efficiency of the unloading process.

5. Anti - Sway Technology: MAXTECH's STS cranes feature anti - sway technology. Sensors are installed on the deck crane to detect any swaying motion of the container during the lifting process. Once detected, the anti - sway system automatically adjusts the crane's movements to counteract the sway. This ensures that the containers are unloaded safely and efficiently, reducing the risk of accidents and delays in the shipping process.

As the shipping industry continues to grow, driven by global trade and the increasing demand for goods, the role of shipyard cranes will become even more significant. Companies like MAXTECH are expected to continue innovating, developing more advanced crane technologies to meet the evolving needs of the industry. This will improve the efficiency of shipbuilding and shipping operations and contribute to the overall growth and competitiveness of the global economy.
