As regaras load case HS, the stresses of load case HZ multiplied by a factor of 1,l may be used. The four stress collectives, So to SJ, denote the relative di frequency with which a dih maximum stress u, is attained or exceeded.

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.

Dimensions and forces due to skewing of a crane with four pairs of track wheels representing different system characteristics 4. Contents Page Field of application Thank you for interesting in our services.

In lieu of a more accurate calculation, the quasi-static forces acting on the structure and resulting from the assessment of themovement of thecentreof ddin of thesystem underthe effect of the driving forces, of the resistances to motion and fin the inertia forces, may be increased by afactor of 1,5 in order to take the dynamic effect into account.

The forces which arise from the subsequent falling back of the jib shall be taken into consideration.

In this respect, 150181 which are not guided shall be deemed to be rigidly attached to the crane;any swinging of the loads shall be ignored. 150181- groups according to stress cycle ranges and stress collectives N2 N3 N4 Over 2. Imposed loads shall be entered in the calculation of the members concerned at the most unfavourable positions, values and directions.

As regards hand rails, a moving horizontal concentrated load acting outwardly or inwardly shall be assumed, amounting to N to allow dij persons carrying loads, N to allow for persons not carrying loads. Other values of the skew angle a shall be agreed.

With regard to compressive stresses in members, the values in the zu1 u2 column shall apply. We are a non-profit group that run this website to share documents. In normal cases, the following fasteners shall be used: The main loads comprise: Examples of this are given in subclause In the case of cranes operating in hot environments, the assumed values shall correspond to the local conditions, e.

All references to systems, dimensions and cross sections made on drawings shall coincide with those made in the calculations. 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 don known.

Price group 16 Sales No. Inertia forces during the start-up and braking of crane trolleys with a central drive mechanism Figure 3.

All permissible stresses for the verification of service strength are rin on the upper side by the permissible stresses applicable to load case HZ in the general stress analysis specified in subclause 7.

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.

Dimensions are given in mm. Travelling speed ZIF, in mimin with rail joints or irregularities road without rail joints or with welded and machined rail joints Over 60 up to 4.

In the case of cranes or trolleys with or without useful load, no negative wheel loads may result from 1. 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 1501-81 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 cin, and as a result of force Sa group of forces XI i.

Please copy and paste this embed script to where you want to embed Embed Script. If the crane is loaded with the large test load, then the small test load shall first be raised to a short distance from dkn floor. Deviations are permitted if the safety of all components concerned is increased thereby beyond any doubt.

P, for lifting classes H 1 and H 2: Accordingly, the 150181- are classified into lifting classes H 1H 2, H 3 and H 4, with different factors p as given in table 2 below. 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 15081-1 such special cases, provided however that the percentage allowed for each individual special cases is not exceeded.

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. If there is an operational possibility of the 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.

The height h, related to the top edge of the rail, shall be entered as follows for the purpose of analysing the web: The distribution of the force S resulting from the skewing of 150188-1 with flanged track wheels is similar 150188-1 that described in subclause 4.
