25t Hydraulic Telescopic Boom Mobile Harbour Crane Marine Deck Crane Ship Crane

Marine Ship Deck Cranes are devices and machinery provided by ships for loading and unloading cargo, mainly including boom devices, deck cranes and other loading and unloading machinery. It is a special crane that performs transportation operations in the offshore environment. It is mainly used for important tasks such as transportation and transfer of cargo between ships, replenishment at sea, and launching and recovery of underwater operating equipment.
The control of marine cranes is mainly divided into two aspects: vertical control to reduce the influence of hull motion and lateral anti-swing to suppress load swing. For vertical control, the common method is to connect the receiving ship through the mechanical structure of the crane ship, and sense its relative motion, so that the length change of the hanging rope is synchronized with the heave motion of the receiving ship, so as to compensate the relative motion of the two ships, and complete the take-off and landing of the load on this basis. This method has special requirements on the mechanical structure of the crane, and also has great limitations on the lifting quality.

Selection of marine cranes

1.The form of driving power often depends on the choice of the shipowner;
2.The size of the lifting capacity mainly depends on the type of cargo to be loaded and unloaded (container ships usually choose 36~40t), and the cost factor should also be considered;
3.The size of the span, usually the outboard span should not be less than about 6m, and the requirements for loading and unloading in the cabin should also be met, and the position of the boom should also be considered;
4.The slewing, luffing and lifting speed of the crane. These parameters have been marked on the product catalogs of various manufacturers. The designer can choose according to the requirements of the ship owner.

Product Advantage

1.High loading and unloading efficiency. Due to the good positioning ability, the handling of goods in the cargo compartment is reduced, and it is not necessary to constantly adjust the position of the boom like the boom device and stop the loading and unloading operation midway. At the same time, the crane can take into account the operations of the front and rear compartments.
2.Easy to operate. There is little preparation before use. Operators operate in the high-position cab, with wide vision and powerful operation.
3. The layout on the deck is relatively simple, occupying a small deck area.
4. It is especially suitable for hoisting heavy cargo. Container ships must have cranes if they have lifting equipment.
