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. If the dun is loaded with the large test load, then the small test load shall first be raised to a short distance from the floor. Example of the distribution ein forces due to tilting of a crane trolley with positive guidance of the lifted load in the direction of crane travel 4.

Dkn a more accurate stress analysis is carried out, the buffer forces shall be multiplied by an oscillation coefficient in accordance with table 6 for the stress analysis, depending on the shape of the don beneath the buffer characteristic.

As regaras load case HS, the stresses of load case HZ multiplied by a factor of 1,l may be used. 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. Where lateral forces due to inertia forces act transversely to the runway, they shall be absorbed by the rails through positive and frictional contact in accordance with the systems adopted for the 150181 structure and the running gear, and in accordance with the type of guiding means used.

In normal cases, the following fasteners shall be used: DIN Part 4 Design loads for buildings: An appropriate substitute mass shall be entered in the calculation in lieu of that of the rotating parts of the running gear. Imposed loads shall be entered in the calculation of the members concerned at the most unfavourable positions, values and directions. The relationships specified in table 19 shall apply for the permissible shear stresses in members and welds and for the permissible shear stresses and hole bearing stresses in fasteners and perforated members.

Not for Resale i: Materials other than the steel grades specified in table 8 may be used on condition that their mechanical properties, their chemical composition and if applicable their weldability are guaranteed by the manufacturer of the material concerned. Verification of the safety against bulging of lates shall also be carried out in accordance with DIN art 1 and Part 2, but in lieu of the factors of safety, vB.

The forces which arise from the subsequent falling back of the jib shall be taken into consideration.

In the case of cranes operating in hot dln, the assumed values shall correspond to the local 150181, e. The relationships specified in table 18 shall apply for the permissible normal stresses in members. It would have been inadvisable to revise the content of the standard at the present time, in view of the general approval which hasgreeted its publication, and mainly because of the current discussions on the national basicstandards relating to steel structures DIN 18 ; furthermore, the efforts of ISOITC 96 to achieve an internationally approved ruling with regard to the loads and load combinations which are to be assumed for the verification by calculation of the performance characteristics of cranes, had to be borne in mind.


Individual elements which are clearlyseparated from the rest, or which form self-contained structural units may 155018-1 classified into different loading groups on condition that their operating conditions are precisely known.

Individual self-contained parts dinn 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. The softer the springing of the hoisting gear, the larger the elasticity of the supporting structure, 150181 smaller the actual hoisting speed at the commencement of the hoisting of the useful load, the smaller and steadier the acceleration and deceleration during changes in the hoisting motion, the smaller the factor.

Forces arising from skewing When a crane skews at a skew angle a,a positive contact force S, dependent on the running gear and supporting structure, is generated on the front guiding means or group of guiding means front in the direction of travel ; these guiding means may consist of a wheel flange or of a guide roller, and as a result of force Sa group of forces XI i.

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 150018-1 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 rin the following symbols: In the case of fillet welds subjected to compressive loading in the direction normal to the weld, such as between web plate and flange plate, no allowance shall be made for contact between the members to be joined.

Travelling speed ZIF, in mimin with rail joints or irregularities road without rail joints or with welded and machined rail joints Over 60 up to 4. Trolley travel Ka 4. We need your help to maintenance this website. 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 dkn order 15081-1 take the dynamic effect into account.

The individual parts of a member etc. In the case of cranes which do not require a verification of stability to be carried out, the test loads are obtained by multiplying the lifted load P by the following factors: The anticipated stress collectives shall be correlated roughly to the idealized stress collectives; if necessary, a cumulative damage calculation may be carried out for this purpose.


Other values of the skew angle a shall be agreed. 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 15018-11, using the same safety factors. All references to systems, dimensions and cross sections dkn on drawings shall coincide with 150188-1 made in the calculations.

Deviations are permitted if the safety of all components concerned is increased thereby beyond any doubt. 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. Instead of adopting a precisely com4. Please fill this form, we will try to respond as soon as possible.

The distribution of the force S resulting from the skewing of cranes with flanged track wheels is similar to that described in subclause 4. In this respect, loads which are not guided shall be 150118-1 to be rigidly attached to the crane;any swinging 1501-1 the loads shall be ignored.

The total number N of stress cycles imposed on a member can be equal to the number of load cycles or of operating cycles, or to a multiple thereof, depending on the type of crane: Loads suspended rin carrying means and freely oscillating loads 150181- not be considered.

The HVRichtlinien are applicable to high strength bolted joints, see clause 2.

DIN 15018-1 (EN – Version 11-1984)

If there is an operational possibility of the tilted trolley tilting back again to its normal position due to the sudden yielding of the obstacle, then the forces arising from such an occurrence shall be taken into account.

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

If the crane is loaded with the 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.

It does not cover craneways, excavators, ropeways, wagon 1508-1 and mining machinery. The height h, related to the top edge of the rail, shall be entered as follows for the purpose of analysing the web: Thank you for interesting in our services.

Accordingly, the cranes are classified into 155018-1 classes H 1H 2, H 3 and H 4, with different factors p as given in table 2 below.

Welded-on lug plates shall be connected with the structure taking 1,5 times the value of the applicable proportion of the stress resultant. In the case of cranes or trolleys with or without useful load, no negative wheel loads may result from 1. The additional loads comprise:
