Referred to as high strength friction grip bolts in this standard. 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.

All references to systems, dimensions and cross sections made on drawings shall coincide with those made in the calculations. 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 ddin systems adopted for the supporting structure and the running gear, and in accordance with the type of guiding means used.

The adoption of a factor of 1,5 is furthermore Examplesof calculating the inertiaforcesfrom the frictional 150118-1 in the case of bridge cranes: Trolley travel Ka 4. An appropriate substitute mass shall be entered in the calculation in lieu of that of the rotating parts of the running gear. A new motion shall only be initiated after the oscillations arising from the previous motion have ceased completely. Where these forces are transmitted 15108-1 the trackwheels, and where there are more than two wheels per runway side, they shall fin uniformly distributed between the outer wheels or outer wheel groups as shown in the examples illustrated in figure 4.

The trolley shall be assumed to be located in the sin unfavourable position for this purpose. Height h for the analysis If the rail rests on an elastic support, the transverse and the longitudinal distribution 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. Angle cleats shall be connected with the structure either taking 1 3 times thevalue 1018-1 proportion of the stress resultant for one leg and the given value itself for the other leg, or taking 1,25 times the value for both legs.

In the case of cranes or trolleys with or without useful load, no negative wheel loads may result from 1. The buffer djn 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.


As far as the supporting structure is concerned, e.

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

In this connection, one should proceed from the smallest wheel load total in don case of speed-synchronized driven track wheels, or from the sum of the smallest wheel 15081-1 in the case of non-speed-synchronized driven track wheels, depending on the type of driving mechanism: With regard to compressive stresses in members, the values in the zu1 u2 column shall apply. DIN Part 4 Design loads for buildings: Price group 16 Sales No.

If there is an operational possibility of cin 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. Size px x x x x We are a non-profit group that run this website to share documents. The additional loads comprise: We need your help to maintenance this website.

See clause 9 for permissible tensile forces on prestressed bolts.

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. We need your help! The four stress collectives, So to SJ, denote the relative cumulative frequency with which a specific maximum stress u, is dni or exceeded.

The permissible tensile stresses in welds for transverse loading may only be used if the plates requiredforthetransmission of the tensile forces, which are thereby stressed transversely in their rolling plane, are suitable for this purpose see table 24, test method associated with letter symbol D. Individual elements which are clearlyseparated from the rest, or which form self-contained structural units may be classified into different loading groups on condition that their operating conditions are precisely known.

If the crane is loaded with the small test load, 15018- the permissible motions shall be carried djn individually with the load situated in the most unfavourable position; however, due care should be observed during the test.


All permissible stresses for the verification of service strength are limited on the upper side by the permissible stresses applicable to load case HZ in the general stress analysis specified in subclause 7. In the case of rope controlled jibs, these negative inertia force effects are limited by the slackening of the ropes, whereby an upward movement of the jib becomes possible.

Accordingly, the cranes are classified into lifting classes H 1H 2, H 3 and H 4, with different factors p as given in table 2 below. YI i and X2i.

Welded-on lug plates shall be connected with the structure taking 1,5 times the value of the applicable proportion of the stress resultant. 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 sin allow for persons not carrying loads.

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. In normal cases, the following fasteners shall be used: The overall stresses governed by the type of crane, load case and verification shall not exceed the permissible stresses in each case, and the safety factors shall not be less than the values specified.

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.

Dimensions are given in mm. In the special cases listed in table 9, the permissible stresses in accordance with tables 10 to 12 may be exceeded, and the factors dinn safety against bulging may be below those specified in DIN Part 1 and Part 2 and in table The individual parts of a member etc.

If the crane is loaded with the large test load, then the small test load shall first be raised dni a short distance from the floor.

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.

The anticipated stress collectives shall be correlated roughly to the idealized stress collectives; if don, a cumulative damage calculation may be carried out for this purpose.

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 The relationships specified in table 18 shall apply for the permissible normal stresses in members.
