In the case of wide-span bridge cranes and portal cranes with separate driving mechanisms, whose supporting structures are not designed to compensate for resistances 1018-2 motion, driving forces and inertia forces, but only for a limited elastic forward motion of one side of the running gear ahead of the other side, special devices shall be provided to dinn that the assumptions on which the design calculation is based are not exceeded.

Self weight factors p The loads acting on the supporting structure are subdivided into main loads, additional loads and special loads. The distribution of the force S resulting from the skewing of cranes with flanged track wheels is djn to that described in subclause 4. Height h for the analysis If the rail rests on an elastic dn, the transverse and the longitudinal vin of the bearing pressure under the rail shall be taken into consideration in their most unfavourable pattern in each case for the calculation of the rail bearing beam and of the rail.

Where several special cases occur simultaneously, the total amount of the maximum permissible stresses or the minimum faktors of safetyshall be limited to the greater of the values allowed for one of such special cases, provided however that the percentage allowed for each individual special cases is not exceeded.

English Choose a language for shopping. The above-mentioned concentrated loads need not be taken into account in respect of any member stressed by lifted loads in accordance with subclause 4. The inertia forces during the start-up and braking of cranes shall be entered in the calculation in each case with the trolley in the most unfavourable position for the member being analysed see figure 3.

The adoption of a factor of 1,5 is furthermore Examplesof calculating the inertiaforcesfrom the frictional contact in the case of bridge cranes: Inertia forces during the start-up and braking of crane trolleys with a central drive mechanism Figure 3. Please help us to share our service with your friends. 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 be used as the basis for the calculation, using the same safety factors.

Dimensions and forces due to skewing of a crane with four pairs of track wheels representing different system characteristics 4. Thank you for interesting in our services. There’s a problem loading this menu right now. 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.

The above loads are grouped into load cases in clause 5. The four stress collectives, So to SJ, denote the relative cumulative frequency with which a specific maximum stress u, is attained or exceeded. As far as the supporting structure is concerned, e. Amazon Inspire Digital Educational Resources. In the special cases listed in table 9, 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 In cases where there is a considerable amount of play between structural members hereinafter briefly referred to as members which move relatively to one another, for example in the case of the rigid mast and the suspension gear of a stripper crane, a factor larger than 1,5 shall be used.

The relationships specified in table 18 shall apply for the permissible normal stresses in members. Provided by IHS under license with DIN No reproduction or networking permitted without license from IHS Not for Resale based on the condition that the driving forces acting on the crane are practically free from backlash.

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. Please fill this form, we will try to respond as soon as possible. In this connection, one should proceed from the smallest wheel load total in the case of speed-synchronized driven track wheels, or from the sum of the smallest wheel loads in the case of non-speed-synchronized driven track wheels, depending on the type of driving mechanism: Dimensions are given in mm.

Imposed loads shall be entered in the calculation of the members concerned at the most unfavourable positions, values and directions.

No such verification need be made for design purposes in respect of subordinate components such as walkways, stairways, platforms, hand rails and cabins. East Dane Designer Men’s Fashion.

Contents Page Field of application Individual self-contained parts of a crane forming integral parts of the complete unit, such as the trolley and the crane bridge or jib, the slewing unit, portal and tower, may be classified into different lifting classes within the limits defined in table 23 for the various types of crane, provided the hoisting conditions are fully known.

Loads suspended from carrying means and freely oscillating loads need not be considered.

It does not cover craneways, excavators, ropeways, wagon tipples and mining machinery. Size px x x x x If the crane is loaded with 1518-2 small test load, all the permissible motions shall be carried out individually with the load situated in the most unfavourable position; however, due care should be observed during the test.
