Method and arrangement for controlling tensioning mechanisms on slings or the like for securing deck cargo on vessels

摘要

The invention relates to a method and an arrangement for controlling tensioning mechanisms 8 on slings 7 or the like for securing deck cargo 6 on hatch covers 4 on vessels. It is important to prevent such load from shifting, at the same time as it must be possible to release, i.e. sacrifice, the load in an emergency situation. According to the invention, the tensioning mechanisms 8 on each hatch cover 4 can be released to free the deck cargo 6 arranged on the hatch cover 4. In the arrangement for implementing this method on a vessel, where the tensioning mechanisms 8 are connected to a control unit which is arranged so as, by virtue of the action of the tensioning mechanisms 8 on the slings 7, automatically to secure the deck cargo 6 with a constant predetermined pressure, the control unit can consist of a compressed-air tank 10 which is loaded with a predetermined level of positive pressure by a compressor 11 which is controlled by signals from a pressure sensor 12 arranged in the compressed-air tank 10, the positive pressure of which brings about the tightening of the tensioning mechanisms 8 to the constant predetermined tensile force.
