A giant made of steel to leave Expom


The Expom company from northern Poland has finalized its order for seven state-of-the-art cranes in the history of the company. One of them is Knuckleboom crane with the weight of the structure itself amounting to 50 tons and made with the application of advanced technological solutions. 

This is the biggest crane with respect to test load produced so far in Expom.  Knuckleboom crane is characterized by two-part, foldable arm structure. A crane of such type is equipped with an additional hydraulic actuator assembled between the main arm and the final arm, which enables to perform the process of folding and unfolding the arms. Owing to the specific structure, Knuckle type crane has more manoeuvre possibilities, which facilitates the transport of cargo substantially.
The machine was equipped with remote on-line operation option. Upon connection of the Internet to the crane controller, remote control of the machine for service purposes is possible from any place in the world. The crane will be used for the operation of off-shore wind farms thus such an option is extremely valuable. Knuckleboom equipment caused ambitious requirements mainly due to the dimensions and diameters of the materials applied. The reach of lifted weight amounts to 24 m and the nominal lifting capacity is 24 tons at maximum extension, which classifies the structure as the biggest crane produced in over 60-year history of Expom S.A.

The structure of the equipped crane reaches the weight of 50 tons and its production involved the use of 80 tons gross of steel. 300 litres of high quality three-layer chemical structure was used for paint coverage of the entire machine. The crane has been equipped with a cabin for the improvement of the operator's working conditions due to the adjustment of the unit for continuous operation. Apart from that, it has been equipped with a camera with a lamp at the end of the arm and the other camera monitoring the operation of the hoist drum, which substantially facilitates the operator's work and ensures greater safety during the performance of tasks. The crane has overloading sensors with weight of the lifted objects, securing the structure against overloading and potential damage.

During the dynamic test, the structure was tested with respect to overloading and it lifted the weight of ca. 30 tons at maximum outreach. Offshore cranes, unlike construction cranes, do not have counterbalance, which is a challenge for test stations. The weight of ca. 30 tons at a distance of 24 m from the crane fixing point generates forces which may extract temporarily designed steel structure of the test station along with the concrete foundation. For the purpose of performance of this test the previous test station in Expom had to be additionally strengthened with anchorage. All cranes have been supervised by the DNV-GL classification association inspector - a Norwegian ship association which monitors the machine production in accordance with global marine standards.
Due to the distance of the company seat in Warmia and Masuria region to the sea the transport itself was a challenge. The crane was dismantled and shipped with vehicle transported as oversized cargo to a port in Gdańsk, where from it was shipped to Scandinavia via a ferry. It will be used for the operation of off-shore wind farms there.

The 4th International Maritime Congress,in retrospect

The 4th International Maritime Congress, which took place on 8-10 June 2016 in Szczecin has been a success. Rafał Domżalski, President of the Management Board of Expom was one of the speakers during the event.  

The event in Szczecin was participated by more than a thousand people, including representatives of maritime, offshore and inland navigation companies as well as government officials. Expom, as a producer of large-size steel structures for offshore sector also played its part in the event. For the first time, one of the speakers during the conference was the President of the Management Board of Expom, Rafał Domżalski, who delivered a presentation titled “A chance in offshore – how to develop international cooperation with Scandinavian countries”.

Why was Expom present at the 4th International Maritime Congress? Although the company is not located by the sea, a considerable portion of its products is delivered to maritime and offshore sector clients. As much as 98% of its production is intended for export, and 40% of products reach the Scandinavian market. Expom shared its experience in international cooperation with the region. During his speech, President Domżalski told the audience how to develop cooperation with maritime sector clients despite geographical distance from the sea.

The inaugural lecture was given by Prime Minister Beata Szydło. Marek Gróbarczyk, the Minister of Maritime Economy and Inland Navigation assessed that a key moment of the Congress was the execution of a letter of intent by the consortium of sector companies relating to the construction of two large ferries for Polish Baltic Shipping in the presence of Prime Minister Beata Szydło. Additionally, while the event was taking place, the Sejm held the first reading of a bill on activation of the shipbuilding industry and complementary production, which shall enter into force on 1 January of the following year.

Expom as a speaker at the 4th International Maritime Congress

In a few days, Rafał Domżalski, President of the Management Board of Expom will be one of the speakers during the 4th International Maritime Congress, which is to take place on 8-10 June.

We would like to kindly invite you to participate in the speech by President Rafał Domżalski, given on 9 June at 12:30 during the panel “Water as a regional generator of development” and titled “A chance in offshore – how to develop international cooperation with Scandinavian countries".

Water and sea constitute a potential that can also be used by companies operating outside the Polish shoreline. The registered office of Expom S.A. is located in Kurzętnik, Warmian-Masurian Voivodeship. Despite its distance from the sea, the company continues to dynamically develop its cooperation with Scandinavian countries thanks to well-established and reliable mechanisms.

Expom has over 60 years of experience in the production of large-size steel structures and 98% of its production is intended for export. As much as 40% of the products are delivered to the Scandinavian market by order of maritime and offshore sector companies. Therefore, there is no doubt that the company has valuable experience in international cooperation with the said region to share.

We look forward to seeing you there!
