Bnr. 487: 80 ton (1915)

In connection with the new dock just opened at Hull by the King of England, we may note that one of the special features of the Joint Dock is being supplied by a well-known Dutch firm. It is the 80-ton derricking and revolving floating crane, the contract for which was given to the Werf Gusto (A. F. Smulders), of Schiedam. The Hull crane will rest on a tower built in a pontoon, having a length of 116ft. by a breadth of 58ft. On top of the tower there is a platform, supporting on one side the jib, on the other side the counter weights and motorhouse, which are enclosed in a structural revolving frame. The crane-jib is fitted with two blocks, one for loads of 40 resp. 80-ton and another for loads up to 10-ton. The loads are balanced by special counter weights, whilst the travelling of the ballast weights will cause the pontoon to remain practically horizontal irrespective of the position or size of the load (up to 30-ton), suspended to the hook, which is of very great value for the efficient and safe handling of the loads. The crane will be capable of lifting, derricking, and revolving, all of which motions are effected by electricity and controlled by one man in the operator’s cabin, fitted high up in the revolving frame, so as to command a clear view of everything going on.

The after deck of the pontoon is specially strengthened to be able to support at least 1-ton per square foot, so that heavy loads can be carried on the aft deck. If it is further known that the pontoon is fitted with 2 propellers, giving the crane a speed of about 5 knots, the great value of such an appliance to the port will become clear, as it will now be possible for the crane to place heavy loads on deck by its own power, and carry them, without the use of a tug, to the place of discharge, to be there deposited in the desired position. If it is further considered that loads of 40 resp. 80-ton can be lifted at a maximum radius of 65ft. and loads up to 10-ton at a maximum radius of 76ft., whilst the crane hook can travel a distance of from 50ft. below to 90ft. above water level, it may confidently be expected this the will prove to be a very valuable acquisition to the growing Port of Hull.

It may be of interest to add that the works of Werf Gusto, which have now grown to such important dimensions, had their inception as far back as 1862, when the late Mr. A. F. Smulders established a small factory at Bois-le-Duc in the southern part of Holland, for the repair of steam engines. In ten years the works were enlarged and transferred to Utrecht, where they were known under the style of Utrecht Iron Foundry and Engine Works, firm of A. F. Smulders. Shortly afterwards the firm acquired the ship-building yard at Slikkeveer-on-Maas, and also the boiler works of Messrs. Benson and Cie, at Grace-Berleur, near Liege. The result was so encouraging and the business expanded at such a rapid rate that the Slikkerveer Yard was unable to keep pace with this ever-growing development. In view of the split-up character of the works, located at two different parts of the country, the firm conceived the plan of centralising the Slikkerveer Yard and the Utrecht Works, which gave birth to the establishment of the present works at Schiedam, near Rotterdam. The Schiedam Works, under the management or Messrs. Henry and Francis &Sliders, cover an area of nearly 15 acres, exclusive of the outer harbour with an area of nearly 10 acres, and extending along the Maas over a length of 1,082 feet. The building slips allow of the building of vessels up to a length of 590 feet.

The Combined works of Schiedam and Grace-Berleur employ at this date some 1,400 men, whilst up to the present time the firm have supplied 478 vessels, in which number the Schiedam Works (started in July, 1905) share to the extent of 173. The specialities of the firm, which have been supplied to all the principal Governments of the world, are:—Stationary and self-propelling ocean-going bucket and suction dredgers with or without hopper, force pump arrangement and patented cutter head, hopper barges of the usual and self-closing type, self-discharging stone-carrying barges, lighters, excavators, cranes of various types, and more particularly floating cranes of great power, patented coaling vessels, bunkering steamers automatically, and of which several may daily be seen operating at the port of Rotterdam, coal transporters, whilst for many years they have successfully applied themselves to the construction of stationary and marine Gusto Diesel Motors.

Gister werd van de werf »Gusto« der firma A. F. Smulders, Schiedam, te water gelaten de stalen romp van een zelfstoomende 80 tons drijvende electrische derrick- en draai-kraan, welke deze firma voor buitenlandsche rekening in aanbouw heeft. De afmetingen van den romp zijn : Lengte 115.0″ ; breedte 58.0″ ; holte 13.9″. De kraan zal in hoofdtrekken gelijk zijn aan de vele andere door deze firma aan buitenlandsche regeeringen en groote scheepswerven geleverde reuzenkranen. Het hoogste punt van den kraanarm bevindt zich bij opgerichten stand op 125 voet boven de waterlijn, terwijl de maximum straal voor lasten van 80 ton 65 voet bedraagt. De hijschsnelheden varieeren van 5 voet per minuut voor lasten van 80 ton tot 40 voet per minuut voor lasten van 10 ton, terwijl de kraanarm met een last van 80 ton binnen 5 minuten 360o kan draaien. Alle bewegingen worden uitgevoerd door onafhankelijke electrische motoren; de stroom hiervoor wordt geleverd door een zich aan boord bevindende electrische centrale, welke eveneens de stroom levert voor de verlichting van het schip. De kraan is voorzien van het vereischte aantal stoom verhaallieren en verder de benoodigde uitrusting.
