Instead of adopting a precisely com4. Self weight factors p The loads acting on the supporting structure are subdivided into main loads, additional loads and special loads. Height h for the analysis If the rail rests on an elastic support, the transverse and the xin 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. 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.

A new motion shall only be initiated after the oscillations arising from the previous motion have ceased completely.

Longitudinal stresses shall remain within the permissible stresses in members specified in table Provided by IHS under license with DIN No reproduction or networking permitted without license from Cin Not for Resale based on the 1501-81 that the driving forces acting on the crane dni practically free from backlash.

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 15018-11 of driving mechanism: Imposed loads dih be entered in the calculation of the members concerned at the most unfavourable positions, values and directions.

In the case of cranes operating in hot environments, the assumed values shall correspond to the local conditions, e.

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 supporting structure and the running gear, and in accordance with the type of guiding means used.

Price group 16 Sales No. In the case of cranes or trolleys with or without useful load, no negative wheel loads may result from 1. The principal corrections, including those which have arisen from the processing of the comments received, are described in the Explanatory notes.

We need your help to maintenance this website. DIN Part 4 Design loads for buildings: 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 15018- be used as the basis for the calculation, using the same safety factors. 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.

Please help us to share our service with your friends. Trolley travel Ka 4. 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 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 dib be assumed for the verification by calculation of the don characteristics of cranes, had to be borne in mind.

Lateral forces acting in opposite directions arise if a distance Is exists between the centre of the masses to be moved and the resultant of the driving forces. 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 15081-1 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: Other values of the skew angle a shall be agreed.

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.


Example of the distribution of forces due to tilting of a crane trolley with positive guidance of the lifted load in the direction of crane travel 4. The six loading groups, B 1 to B 6, are correlated to specific ranges of the stress cycles and to specificstress collectives in accordance with subclause 7. Testing with test load Pk or Pg shall be carried out in the absence of wind. Not for Resale i: In the case of fillet welds subjected to compressive loading in the direction normal to the weld, such as between 15081-1 plate and flange plate, no allowance shall be made for contact between the members to be joined.

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 dln or of a guide roller, and as a result of force Sa group of forces XI i. 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.

Inertia forces during the start-up and braking of crane trolleys with a central drive mechanism Figure 3. If the crane is loaded with the small test load, all the 150181 motions shall be carried out individually with the load situated in the most unfavourable position; however, due care should be observed during the test.

1508-1 An appropriate substitute mass shall be entered in the calculation in lieu of that of the rotating parts of the running gear. Transverse stiffenings shall be arranged at spacings not exceeding 10 sin r, whose moment of inertia 1,calculated in accordance with DIN Part 2 February x editionRi With regard to compressive stresses in members, the values in the zu1 u2 column shall apply.

Deviations are permitted if the safety of all components concerned is increased thereby beyond any doubt.
