Abstract:
A bearing block (12) is used to support a building element (10), in particular a building element subject to different loads, on a bearing body (14), when alignment errors and/or relative movements are to be expected because of possible deformations of the building element, in particular tilting and/or sliding movements. The bearing block (12) has a load receiving part (16) to be secured on the bearing body (14) or the building element (10) and a supporting part (18) which rests on the load receiving part (16). The bearing block (12) is characterised in that at least one layer of balls (48) is provided between the load receiving part (16) and the supporting part (18), and in that preferably at least one anchoring arrangement (50) is provided which allows for alignment errors or relative movements within predetermined limits, but which prevents the load receiving part (16) and the supporting part (18) from accidentally separating from each other.
Abstract:
A slide bearing, suitable in particular for transmitting high bearing forces when the bearing partners are slightly and slowly moved with respect to each other, has a bearing block (1) or support into which are incorporated rods (30) made of a friction-reducing material, in particular glass-reinforced polytetrafluoroethylene (PTFE), which extend in a substantially perpendicular direction to the bearing surface. The bearing partner rests on the free face of the rods.
Abstract:
In a support for ship hatchway covers, a supporting rod (9) is arranged between the bearing block (3) secured to the coaming plate (1) and the supporting block (4) secured to the hatchway cover (5). The supporting rod (9) transmits on the one hand the vertical forces which result from the inherent weight of the cover (5) and from any deck cargo, and on the other hand, by lateral deflection, allows the supporting block to move sideways in relation to the bearing block (3). This lateral deflection is made possible by an elastically flexible support rod (9) or by movably mounting the supporting rod on both the bearing block and the supporting block.
Abstract:
A pair of supports for a hatch cover of container ships comprises an upper support (21) and a lower support (20). The lower support (20) is welded to a hatch bank and consists of wear-resistant hard steel. The upper support (21) is comprised of a base body (22) welded to the hatch cover and of a wear-resistant waste part (23) made of plain steel. The wear-resistant waste part (23) is engaged with a pin (25) in a hollow portion (24) of the base body (22), thereby providing for the safety of the locking. The wear-resistant waste part (24) may be easily replaced by loosening the screw (26). The upper support (21) is displaced as the hull moves and it is loaded by the containers piled on the hatch cover. The inevitable wear occurs only on the lower side (27) of the wear-resistant waste part which is easy to replace.
Abstract:
The invention provides a multi-layer hatch cover support pad (50) for supporting a hatch cover (8) on a coaming structure (10) of a ship (2). The multi-layer hatch cover support pad (50) comprises an outer wear surface (54) for sliding against a mating surface (14) provided on the hatch cover (8) or the coaming structure (10), a wear layer (52) comprising first and second opposite sides (54, 56), the first side defining the outer wear surface (54), the wear layer -{32} comprising a first plastic material and, a base layer (58) comprising third and fourth opposite sides (80, 82), the third side (60) being joined to the second side; (56). The base layer (58): comprises a second polymer material which is less abrasion resistant than the first plastic material. By making the base layer (58), which in practice makes up the main part of the multi-layer hatch cover support pad (50), out of the second polymer mate- rial, the cost of the multi-layer hatch cover support pad (SO) is decreased. The multi-layer Hatch cover support pad may (50) further comprise an interna! wear indicator body (80) for indicating wear of the wear layer (52) and/or an identification unit (110) for identifying: the multi-layer hatch cover support pad (50), A method cf producing the multi-layer hatch cover support pad (50), as well as a use of the multi-layer hatch cover support pad (50), is also provided.
Abstract:
A vessel hatch cover has a first plurality of sliding panels that allow a bulk hose receptacle to move across the width of a vessel hold without exposing the underlying bulk material. The first plurality of panels forms a loading portion which itself forms one of a second plurality of second sliding panels which allow the loading portion to move fore and aft so as to position the bulk hose receptacle in virtually any location over the hold without ever exposing the underlying hold to the elements.
Abstract:
The present invention relates to a slide support for a hatch cover employed aboard a cargo ship to cover the hatchway to a ship's cargo space, said slide support being adapted between the hatchway coaming and the hatch cover attached to either of these for the purpose of transmitting vertical forces from the ship's hatch cover to the ship's hull, and said slide support further comprising a slide piece holder integrally attached by, e.g., welding, and slide pieces insertable in said holder. The invention is implemented by providing the surface of the slide piece holder (1') intended to hold the slide pieces (2') with at least two recesses for the slide pieces, essentially separated from each other so that at least one slide piece (2') can be inserted in each recess.
Abstract:
A vessel hatch cover has a first plurality of sliding panels that allow a bulk hose receptacle to move across the width of a vessel hold without exposing the underlying bulk material. The first plurality of panels forms a loading portion which itself forms one of a second plurality of second sliding panels which allow the loading portion to move fore and aft so as to position the bulk hose receptacle in virtually any location over the hold without ever exposing the underlying hold to the elements. Thus, loading can occur in inclement weather without fear of contamination, reducing demurrage and in port vessel time.
Abstract:
A friction bearing, in particular for mounting a hatchway cover (2) on a ship, has an upper section (6) at the load side and a support that carries said section, a base plate (12) that can be secured to a supporting body and a sliding block (8) mounted on the base plate (12). The sliding block (8) has a sliding lining (16) which in operation is in contact over its whole surface with the lower side of the upper bearing section (6). The sliding block (8) is mounted on the base plate (12) in a movable manner by means of an elastic intermediate element (10) arranged between the base plate (12) and the sliding block (8). A layer (14) of polytetrafluoroethylene (PTFE) is permanently secured to the lower side of the upper bearing section (6) in contact with the sliding lining (16).
Abstract:
Hatch assembly for an opening in the coach roof of a boat. The hatch assembly (4) comprises a roof part (7), side walls (10) and a front wall (8). The side and front walls are movable between a position in, or substantially parallel to, the plane of the roof part and another position at an angle to the roof part.
