Electric Drive Marine Jib Crane [Model 80 T]

We offer electric drive cranes in addition to our core range of hydraulic models. Their application is ideal when meeting strict environmental regulations or specific customer requirements. The electric drive provides enhanced energy efficiency, ensures operational stability, and reduces maintenance costs while maintaining key performance indicators for reliability and lifting capacity.

The Model 80T crane is designed for lifting vessels weighing up to 80 tons at the quay wall. Flexible hoist positioning (with a 7m longitudinal pitch and 6m to 11.5m transverse pitch along the boom) allows for handling vessels of various dimensions. A powerful 2-meter pedestal mounting guarantees the stability and reliability of the structure even under maximum load.

Marine Jib Crane 80T 3D Model Pedestal

Pedestal

(highlighted in blue)

The pedestal serves as the foundation for mounting the crane’s boom and equipment. The welded steel profile structure is secured to the foundation with flange bolts, providing high rigidity and reliability. An additional weathertight door and lifting lugs simplify maintenance and installation.

Foundation

(highlighted in blue)

The foundation ensures the absolute stability of the crane, fully absorbing all operational loads. Its concrete base is engineered considering specific conditions: geographical location, crane-induced loads, and soil properties. Secure attachment of the pedestal is guaranteed by an anchoring system embedded in concrete and fixed with a flange. This solution enables the installation of cranes of various weights and heights.

Boom

(highlighted in yellow and blue)

The boom is a welded steel structure serving as the mounting base for all crane components. It is equipped with counterweights, traverse beams, railings, and service platforms to ensure personnel safety. The inclusion of lifting lugs allows for various loading and unloading operations, providing a comprehensive solution for reliable performance.

Hoists

(highlighted in yellow)

The hoists, operating in mirror mode, handle the lifting and lowering of the load. The distance between the units is adjusted via reliable electric motors that move the hoists along the traverse beams. All power cables are either concealed within the boom or protected by braiding, guaranteeing durability and stable operation.

Why 80 Tons Is Not Just a Number

Imagine a yacht or a small vessel. Elegant, yet heavy—tens of tons of metal, plastic, and fuel. How do you lift this behemoth out of the water to clean the hull, paint it, or simply store it for the winter? You can’t just pick it up with any crane; a vessel must be lifted with surgical precision, ensuring even load distribution and protecting the hull from damage. For this challenging task, engineers designed the machine we are looking at today: a giant dockside jib crane.

Not Just a Crane, but Infrastructure

Unlike the tower cranes commonly seen on construction sites, this crane is stationary. It is permanently anchored into a concrete base at the water’s edge. Its primary mission is to lift vessels weighing up to 80 tons from the water’s surface, move them along the quay, and gently lower them onto land or back into the water. This is not merely a lifting machine; it is a key element of a shipyard or boat house infrastructure.

What It Is Made Of: A Steel Giant

Imagine a massive steel structure as tall as a ten-story building. It consists of several main components. First, there is the massive pedestal, secured to the foundation by heavy-duty anchor bolts embedded in concrete. The interior of the pedestal is hollow, housing the ladders that maintenance personnel use to reach the top. This pedestal alone weighs over 21 tons.

Mounted atop the pedestal via a special slewing unit (a giant bearing several meters in diameter) is the boom. This is also a welded steel structure, tens of meters in length. To prevent the crane from tipping while lifting a load, massive concrete counterweights—each weighing nearly 17 tons—are positioned at the rear of the boom. The total weight of this giant exceeds 70 tons, and with ballast included, it reaches a full 100 tons!

How It Works: Four Hands Instead of One

The most fascinating feature of this crane is its “hands.” Instead of one large hook, it features four independent hoists (essentially four smaller winches), each capable of lifting 20 tons. These hoist hooks attach to the vessel at four points. This design is specifically intended for lifting long and heavy boats, ensuring even load distribution and preventing the hull from tilting or breaking under its own weight.

The entire system is operated using small consoles. The primary mode is via radio link. An operator can walk along the pier holding the console and command the crane remotely: rotate the boom, lower the hooks to the water, hitch the vessel, and pull it out. In case the radio connection is lost or the battery dies, there is a backup console on a long cable.

Equipment at the Edge of Capability

The crane must be not only strong but also extremely precise. The documentation specifies a hook hoisting speed of just 1.6 meters per minute. This is neither an error nor slowness. A vessel, especially when first emerging from the water, behaves unpredictably. A sudden movement could create a dangerous load or cause the multi-ton cargo to swing. Therefore, the operator lifts it literally millimeter by millimeter: first just a bit to allow water to drain from the hull, and only then upward. The boom’s slewing angle is 340 degrees — nearly a full circle — which is sufficient to service a large area of the water basin.

Safety First

As befits serious machinery, the crane is packed with safety systems. It will not allow a load heavier than the rated capacity to be lifted — an interlock will trigger. If strong winds pick up, the mechanisms will stop. Special limit switches monitor the movement of the hoists, preventing them from crashing into the end stops. In case of an emergency, red emergency stop buttons are positioned across the entire crane.

In Conclusion

This crane is a prime example of engineering where brute force (the ability to lift 80 tons) is combined with surgical control precision. It might not be as widely discussed as new smartphone models, but without these quiet industry heroes, ship repair and maintenance would be impossible. Now, when looking at a yacht lifted from the water, you will know exactly what a sophisticated machine stands behind it.
