10、 under the direction of the Rubber Standards Committee and is identical with ISO 5285 “Conveyor belts Guide to storage and handling” published by the International Organization for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitabl
11、e for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. Wherever the words “International Standard” appear, referring to this standard, they should be
12、 read as “British Standard”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-refere

15、 10-19991 1 Scope and field of application This International Standard provides a guide to the most suitable conditions for the storage and the handling of conveyor belts. 2 Reference ISO 2230, Vulcanized rubber Guide to storage. 3 Packing Belting is generally despatched in roll form and either simp
16、ly bound around the outside lap or protected by paper, waterproof plastic material or rubberized fabric, or contained in timber crates or drums. 4 Storage 4.1 General conditions of storage The general conditions of storage are specified in ISO 2230. 4.2 Form of storage Belting should be stored coile
17、d with the central axis horizontal and raised off the floor on wood or pallets. Any covering material such as waterproofed plastic film or rubberized fabric which may have collected moisture should be removed to avoid mildew formation; otherwise the belting may be stored in the original package. Bel
18、ting may be stacked several rolls high provided that the resultant pressure does not collapse or distort the centres. 5 Lifting To lift a roll of belting, the preferred method is to insert a steel bar through the (circular or square) bore of the roll centre and to attach rope or chain slings hanging
19、 down from the spreader bar of a lifting apparatus to the laterally protruding ends of the steel bar (see Figure 1). The spreader bar shall be longer than the roll width to avoid any damaging of the belt edges by the ropes or chains. If a textile or plastic sling of sufficient strength and length is
20、 available as lifting means, this may be fed or drawn through the mandrel bore and used without a spreader bar (see Figure 2). No attempt should be made to hook into the outer lap of the roll, as the belt when so strained is not capable of carrying the entire roll and the end of the belt length woul
21、d be damaged. Steel ropes or chains should not be used as lifting means unless a spreader bar or, alternatively, a suitable beam of sufficient length is available, so that no contact between the ropes or chains and the belt edges is possible. On no account should a sling be tied around the circumfer
22、ence of a roll of belting for lifting. Unequal load distribution might cause the roll to fall out sideways (see Figure 3), risking injury to personnel. 6 Transport on short distances 6.1 Fork lift trucks A conventional truck of adequate load capacity may be used provided that care is taken not to da
23、mage the outer laps of belting with the forks (see Figure 4). 6.2 Without handling facilities Where no mechanical handling facilities are available, belting may be rolled along the floor provided that its surface is not liable to damage the belting and that the direction of movement tightens the coi
24、ls. Loosening of coils or telescoping will cause trouble in handling.
