DIN 15018-1 (EN – Version 11-1984)

Materials other than the steel grades specified in table 8 may be used on condition that their mechanical properties, their chemical composition and if 115018-1 their weldability are guaranteed by the manufacturer of the material concerned.

We need your help! 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: 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 The above loads are grouped into load cases in clause 5.

All references to systems, dimensions and cross sections made on drawings shall coincide with those made in the calculations. Zs is the distance, measured at right angles to the direction of motion, of the resultant of the driving forces from the centre of mass S of the crane bridge, trolley and lifted load; a is the centre-to-centre distance of the wheels or of the guide roller or groups of guide rollers for the absorption of the lateral forces, see also figure 4.

Contents Page Field of application 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.

If the worst case under the above conditions is not bvident from the correlated stresses U, Uy and t,separate verifica. The permissible tensile stresses di 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.

XR R is the sum of all wheel loads arising from self weights System Position h of the slip pole and factor A.

If the above rules are followed, the specified bolt or rivet bearing stresses shall also apply for members. Please help us to share our service with your friends. The relationships specified in table 18 shall apply for 155018-1 permissible normal stresses in members. DIN Part 4 Design loads for buildings: Not for Resale i: 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. With regard to compressive stresses in members, the values in the zu1 u2 column shall apply.

In cases where is less than -1, shallbe entered at a value of A new motion shall only be initiated after the oscillations arising from the previous motion have ceased completely. The forces which arise from the subsequent falling back of the jib shall be taken into consideration. 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 xin than the values specified.

Loading groups according to stress cycle ranges and stress collectives N2 N3 N4 Over 2. 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.

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.

Welded-on lug plates shall be connected with the structure taking 1,5 times the value of the applicable proportion of the stress resultant. 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.

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. 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.

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

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

Where in composite members a stress resultant is passed on by a system of welds. 150018-1 are a non-profit group that run this website to share documents.
