41、s, namely DIN 15 O1 8 in respect of cranes, DIN 15019 in respect of stability and DIN 4132 for crane runways are given in detail in the Explanations to DIN 15018 Part 1. DIN 15019 contains - in accordance with DIN 15018 Part 1, April 1974 edition, Section 7.5 -only the rules for the required demonst
42、rations of stability, and in fact in two parts: Part 2 “Stability of non-rail mounted mobile cranes“ and Part 1 of the present Standard, which applies to all other cranes with the exception of floating cranes in accordance with DIN 15018 Part 1. DIN 15019 Part 1 supersedes para.22of DIN 120Part 1. T
43、his separation enables both the wide range of current models and future developments to be taken into account. Re Section 1 - Range of application and purpose Cranes which are rigidly connected to foundations or to buildings do not fall under the range of application of this Standard, since in this
44、case it is not the stability, but the stresses in the corresponding structural parts that are to be proven, e.g. compressions in the ground joint, strength of the anchoring ropes and the reliability of the anchorages. When conducting these proofs, it is recommended that the conditions for mobile rot
45、ary tower cranes as specified in Table 3 should be used as the basis. Re Cection 4 - Classification of cranes In accordance with Table 1 “Crane types“, crane type 2 also includes rotary tower cranes which are moved in a similar fashion to truck-mounted, movable and track- laying cranes, but in which
46、 the tower is clamped to the rotating platform and where considerable time and effort would be required on order to remove the tower to ground level, thus escaping the effect of a rising storm. On the other hand, in the case of truck-mounted, movable and track-laying cranes, the main jib is always h
47、inged to the rotating platform in such a way that it can be rotated about a horizontal axis and can be maintained in its upright operating position by adjusting ropes. Operation of the adjusting mechanism is all that will be required in order to place the jib system on the ground in a reasonably sho
48、rt period of time. The decisive criterion is the possibility of removing the supporting structure from the effects of a rising storm in a reasonably short period of time. The rail-mounted rotary craneson standard gauge or other types of railway track mentioned in Table 1 under crane type 3 are crane
49、s which move only within a limited working area. They may not leave this area; their running gear is not suitable for the speeds usually attained on the roads. On the other hand, railway cranes of crane type 4 are at the disposal of the railway administration departments and are used by them in an extremely wide range of models for the most varied of purposes. The stability requirements also differ greatly depending on the use to which they are put and for this reason may not be included in the general Standard, but remain subject to special agreements. Also, in the case of cranes of c
