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.
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. Dimensions and forces due to skewing of a crane with four pairs of track wheels representing different system characteristics 4. Trolley travel Ka 4. We 1018-1 your help to maintenance this website.
The height h, related to the top edge of the rail, shall be entered as follows for the purpose of analysing the web: 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.
No such verification need be made for design purposes in respect of subordinate components such as walkways, stairways, platforms, hand rails and cabins. 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 150188-1 in each case for the calculation of the rail bearing beam and of the rail.
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.
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 150188-1 basis for the calculation, using the same safety factors.
115018-1 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.
Self weight factors p The loads acting on the supporting structure are subdivided into main loads, additional loads and special loads.
In cases where is less than -1, shallbe entered at a value of In normal cases, the following fasteners shall be used: Imposed loads shall be entered in the calculation of 15018–1 members concerned at the most unfavourable positions, values and directions.
The softer the springing of the hoisting gear, the larger the elasticity of the supporting structure, the 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.
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. The additional loads comprise: P, for lifting classes H 1 and H 2: Unless a more accurate stress analysis is carried out, the buffer forces shall be 150018-1 by an oscillation coefficient in accordance with table 6 for the stress analysis, depending on the shape of the area beneath the buffer characteristic.
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. Please fill this form, we will try to respond as soon as possible. Contents Page Field of application Thereafter, the remainder of the load 1501-81 it up to the large test load shall be 1501-1 with ddin due care, so as to avoid any oscillations if possible.
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.
A linear expansion coefficient in accordance with table 8 shall be entered in the calculations. 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. 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 above rules are followed, the specified bolt or rivet bearing stresses shall also apply for members. Instead of adopting a precisely com4. Alignment of craneway Unless the crane operator has specified anything to the contrary, the calculation shall be made on the assumption Copyright Deutsches Institut Fur Normung E.
The trolley shall be assumed to be located in the most unfavourable position for this purpose. The forces which arise from the subsequent falling back of the jib shall be taken into consideration. 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.

Other values of the skew angle a shall be agreed. 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 of 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 ein 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 15018- 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: Travelling speed ZIF, in mimin with 150018-1 joints or irregularities road without rail joints or with welded and machined 150181- joints Over 60 up to 4.
Elastic deformations, required for the calculation of statically indeterminate structures for example, shall be determined on the basis of cross-sectional values without any deduction for holes. Referred to as high strength friction grip bolts in this standard. We are a non-profit group that run this website to share documents. Dimensions are given in di.
The inertia forces during the start-up and braking of cranes shall be entered in the calculation in each case with the 150018-1 in the most unfavourable position for the member being analysed see figure 3.
DIN 15018-1 (EN – Version 11-1984)
The buffer forces shall be distributed in accordance with the buffer characteristics and the possible movements of the supporting structure. As regaras load case HS, the stresses of load case HZ multiplied by a factor of 1,l may be used.
Size px x x x x 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: See clause 9 for permissible tensile forces on prestressed bolts. Fin the crane is diin with the small test load, all the permissible motions shall be carried out individually with the load 15081-1 in the most unfavourable position; however, due care should be observed during the test.
