The buffer forces Pu due to cranes or trolleys crashing against stops or colliding with one another shall be limited by buffers dih by similar energy absorbing means.

For cranes with a total of n pairs of track wheels arranged each on an axis i, and of which m are speed-synchronized, and whose wheel loads R I i on side 1 and R2 i o n side 2are of equal magnitude respectively for each side, and assuming the usual tolerances for track wheel diameter, axial parallelism of track wheel bores and position of the runway, with a linearized frictional contact relationship applying equally to longitudinal and transverse slip, the following applies: In this respect, loads which are not guided shall be deemed to be rigidly attached to the crane;any swinging of the loads shall be ignored.

As regards hand rails, a moving horizontal concentrated load acting outwardly or inwardly shall be assumed, amounting to N to allow for persons carrying loads, N to allow for persons not carrying loads. The four stress collectives, So to SJ, denote the relative cumulative frequency with which a specific maximum stress u, is attained or exceeded.

It does not cover craneways, excavators, ropeways, wagon tipples and mining machinery. In cases whereadditional testsare carried out to determine stresses within the framework of the design loads specified in clauses 4 and 5, the test results may 1501-2 used as the basis for the calculation, using the same safety factors.

Trolley travel Ka 4. Transverse stiffenings shall be arranged at spacings not exceeding 10 x r, whose moment of inertia 1,calculated in accordance with DIN Part 2 February x editionRi Other values of the skew angle a shall be agreed.

In the special cases listed in table 15081-2, the permissible stresses in accordance with tables 10 to 12 may be exceeded, and the factors of safety against bulging may be below those specified in DIN Part 1 and Part 2 and in table The permissible stresses are equal for each loading group and are dependent upon the stress collective and the number of stress cycles; they have been laid down for various steel grades,types of stress, notch cases and limiting stress ratios, see subclause 7.

ComiXology Thousands of Digital Comics. Amazon Inspire Digital Educational Resources. Amazon Rapids Fun stories for kids on the go. Unless a more accurate calculation is made, Ki shall be distributed proportionally between both sides of the craneway without considering any inertia force effects or any skidding of the driven track wheels see figure 6.

The distribution of the force S resulting from the skewing of cranes with flanged track wheels is similar to that described in subclause 4.

As far as the supporting structure is concerned, e. We need your help! P, for lifting classes H 1 and H 2: Factors A, A, ix, Al and A2 ix, A2 iy for the calculation of forces S, XI i, Yi i, X2i,YZiand of the position h of the slip pole are determined in accordance with tables 4 and 5 by the dimensions of the crane according to figure 5, by the position of theoverall centre of mass due to theself weights and to the lifted loads, and by the running gear system and structure system as defined by the following symbols: In lieu of a more accurate calculation, the quasi-static forces acting on the structure and resulting from the assessment of themovement of thecentreof mass of thesystem underthe effect of the driving forces, of the resistances to motion and of the inertia forces, may be increased by afactor of 1,5 in order to take the dynamic effect into account.

In the case of cranes operating in hot environments, the assumed values shall correspond to the local conditions, e. The buffer forces shall be distributed in accordance with the buffer characteristics and the possible movements of the supporting structure.

The principal corrections, including those which have arisen from the processing of the comments received, are described in the Explanatory notes.
