Problems solved by technology

However, previously known trucks of this type exert their lifting or supporting forces at the area of ​​the central balance point on the underside of each panel, thus causing the above-mentioned negative effects and problems associated with undesired deformations
Also, when the ship is not fully in the waves, problems arise due to deck panels getting stuck due to displacement between them and the hull

Embodiment Construction

[0023] according to figure 1 , a drivable truck 1 on a Pure Car / Truck Carrier (Pure Car / Truck Carrier, PCTC, (not shown)) is shown for lowering / lifting the deck panel 11 (in figure 1 not shown in ), which includes as its main components a chassis 2, four hydraulically (in this embodiment) operated support columns 3 fixed thereto, a hydraulically operated (in this embodiment) scissor lift 4 , lifting frame 5 and open but protected driver's cabin 6. Drivable truck 1 also includes a deck 8 for facilitating its manipulation and on PCTC deck 8 (not in figure 1 extract the four guide wheels 7 of the location shown). At its respective corners, the truck 1 comprises controllable and pivotably arranged support beam arms 9, suitably hydraulically actuated (in this embodiment) extensions 10 (at figure 1 Not shown in ) is located inside it, so that each arm 9 can be further extended according to actual needs. The angle of pivoting and the length to which each extension 10 extends is c...

Abstract

Method and device in lowering / lifting a carrying deck panel (11) for carrying cars / trucks inside a hold aboard a Pure CarlTruck Carrier (PCTC), while using at least one lifting device (1) having lifting means applied under said deck panel (11) being reversibly raisable and / or extendable and / or liftable and / or lowerable to lift or lower said deck panel (11). Said lifting means (9, 10, 15) are applied at a number of choice specifically calculated for each deck panel (11) dependent upon which panel is to be lifted / lowered. The lifting means (9, 10, 15) is / are to be controlled from rest position / -s to provide a distributed lifting force pattern below said deck panel (11) to lift or lower the same by applying lifting force / -s in an individually controllable pattern thereon, so that the deck panel (11) when in an unloaded state can be lowered and lifted undeflectedly or deflected in a predictable fashion.

Description

technical field [0001] The present invention relates to a method and apparatus in an intercontinental car and truck carrier for transporting cars and trucks of different sizes from their manufacturers, almost without exception, from long abroad across at least one ocean. More specifically, the method involves the use of lifting means applied under deck panels arranged in the cargo holds of such ships, which are reversibly liftable and / or extendable and / or liftable and / or lowerable to raise or lower the deck panel to different lockable height positions to allow loading of loads of different sizes. [0002] In order to do this in an economical manner, these transport ships have been carefully optimized and have thus become very large and are today limited in size mainly by the routes they travel at sea, for example through the waterways of Panama. And indeed, the widening of this waterway was a consequence of the need for wider ships for this type of trade. On such ships the d...
