The four stress collectives, So to SJ, denote the relative cumulative frequency with which a specific maximum stress u, is attained or exceeded. Lateral forces acting in opposite directions arise idn a distance Is exists between the centre of the masses to be moved and the resultant of the driving forces. 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.

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. Height h for the analysis If the rail rests on an elastic support, the transverse and the longitudinal distribution of the 15081-1 pressure under the rail shall be taken into consideration in ddin most unfavourable pattern in each case for the calculation of the rail bearing beam and xin the rail.

Thereafter, the remainder of the load making it up to the large test load shall be attached with all due care, so as to avoid any oscillations if possible. If the crane is loaded with the large test load, then the small test load shall first be raised to a short distance from the floor.

Dimensions are given in mm. Loads suspended from carrying means sin freely oscillating loads need not be considered. Where these forces are transmitted through the trackwheels, and where there are more than two wheels per runway side, they shall be uniformly distributed between the outer wheels or outer wheel groups as shown in the examples illustrated in figure 4. 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.

All permissible don for the verification of service strength are limited on the upper side 1508-1 the permissible stresses applicable to load case HZ in the general stress analysis specified in subclause 7.

The distribution of the force S resulting from the skewing of cranes with flanged track wheels is similar to that described in subclause 4. Not for Resale i: Unless a more accurate calculation is made, Ki shall be distributed proportionally between both sides of the craneway without considering any inertia 15108-1 effects or any skidding of the driven track wheels see figure 6.

Individual self-contained parts of a crane forming integral parts of the complete unit, such as the trolley and the crane bridge or 51018-1, 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. Instead of adopting a precisely com4. Dimensions and forces due to skewing of a crane with four pairs of track wheels representing different system characteristics 4.

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, dun 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.

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.

In normal cases, the following fasteners shall be used: Loading groups according to stress cycle ranges and stress collectives N2 N3 N4 Over 2. Where in composite members a stress resultant is passed on by xin system of welds. Deviations are permitted if the safety of all components concerned is increased thereby beyond any doubt. A linear expansion coefficient in accordance with table 8 shall be entered in the calculations.

As regaras load case HS, the stresses of load case HZ multiplied by a factor of 1,l may be used. Thank you for interesting in our services.

The buffer forces shall be distributed in accordance with the buffer characteristics and the possible movements of the supporting structure.

The forces which arise from the subsequent falling back of the jib shall be taken into consideration. An appropriate substitute mass shall be entered in the calculation in lieu of that of the rotating parts of the running 1518-1. Unless 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 area beneath the buffer characteristic.

If the above rules are followed, the specified bolt or rivet bearing stresses shall also apply for members.

The adoption of a factor of 1,5 is furthermore Examplesof calculating the inertiaforcesfrom the frictional contact in the case of bridge cranes: 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.

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 Provided by IHS under license with DIN No reproduction or networking permitted without license from IHS Not for Resale based on the condition that the driving forces acting on the crane are practically free from backlash. The HVRichtlinien are applicable to high strength bolted joints, see clause 2.

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.

Size px x x x x 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 to allow for persons not carrying loads. With regard to compressive stresses fin members, the values in the zu1 u2 column shall apply.

DIN Part 4 Design loads for buildings: 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 in order to take the dynamic effect into account. The above loads are grouped into load cases in clause 5. 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 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 individual parts of a member etc.
