Freight Containers and Pallets Sectional Committee, TED 12

FOREWORD

This Indian Standard (First Revision) was adopted by the Bureau of lndian Standards, after the draft finalized by theFreight Containers and Pallets Sectional Committee had been approved by the Transport Engineering Division Council.

This standard was originally published in 1981. This revision has been undertaken to align with the current practicesand to include 12 m (40 feet) spreaders.

When atypical 4-leg sling is used for lifting a freight container, compressive stresses are developed along the horizontalroof line of container. Containers are not constructed to take this stress at the roof plane. Therefore, spreaders are usedfor handling of freight containers which take these compressive stresses and prevent the container from any damage.

Applicable statutory requirements pertaining to container spreaders shall be adhered to.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observedVr dculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960 ‘Rules for

rounding off numerical values (revised)’. The number of significant places retained in the rounded off value should be

the saline as that of the specified value in this standard.

3 TERMINOLOGY

For the purpose of this standard, following definitions,shall apply.

3.1 Fixed Spreaders — Spreaders constructed of fixedlength of 6 m (20 feet) or 12 m (40 feet).

3.2 Telescopic Spreaders — Spreaders constructed forextension tlom 6 m (20 &et) to 12 m (40 feet).

3.3 Sling Height (For Fixed Spreader Only) — Heightmeasured on a vertical plane passing through the centre,from a point on the top of spreader to a point where thesling will intersect, if produced, on this plane for a particular

sling angle.

3.4 Head Block (For Telescopic Spreaders) — An

attachment fitted with gantry cranes on which spreader isto be attached.

3.5 Sling Angle —Angle made by the sling on a verticalplane, passing through the diagonals of the spreader framewith the horizontal plane.

4 DIMENSIONS AND TOLERANCES

Length and width of spreader frames shall be based on

centre distance of twistlocks and in accordance withIS 6566 and Table 1. An illustrative sketch of spreader is

shown in Fig. 1.

5 MATERIAL FOR SPREADER ASSEMBLY
