(Amendment)Crane safety - General design - Part 2: Load actions
Crane safety - General design - Part 2: Load actions
This document specifies load actions and load combinations for the calculation of load effects as basis for the proof of competence of a crane and its main components. It will be used together with the other generic parts of the EN 13001 series of standards, see Annex E. As such they specify conditions and requirements on design to prevent mechanical hazards of cranes and provide a method of verification of those requirements.
NOTE Specific requirements for particular types of crane are given in the appropriate European product standards for the particular crane type, see Annex E.
The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and reasonably foreseeable misuse. Clause 4 of this document provides means to reduce or eliminate the risks of mechanical failures due to the following:
a) rigid body instability of the crane or its parts (tilting);
b) exceeding the limits of strength (yield, ultimate, fatigue);
c) elastic instability of the crane or its parts or components (buckling, bulging).
The hazards covered by this document are identified by Annex G.
This document is not applicable to cranes that are manufactured before the date of its publication as EN.

2 Modifications to the Introduction
Replace the whole clause with the following:
“This document has been prepared to be a harmonized standard to provide one means for the mechanical
design and theoretical verification of cranes to conform to the essential health and safety requirements
of the EU Directive 2006/42/EC (Machinery), as mentioned in Annex ZA.
This document is a type-C standard as stated in the EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards, for machines that have been designed and built according to the requirements of this type-C
standard.”

“This document is not applicable to cranes manufactured before the date of its publication.”
4 Modifications to Clause 2, “Normative references”

“Consideration shall be given to internal load effects in mechanisms due to exceptional loads given in
4.2.4, such as:
— 4.2.4.4, buffer forces;
— 4.2.4.7, emergency cut-out;
— 4.2.4.8, dynamic cut-off by lifting force limiter;

In 4.2.2.1, replace the 1 paragraph with following:
“When lifting the load off the ground or when releasing the load or parts of the load, the crane structure
is under effect of vibration excitation, which shall be taken into account as a load effect. The gravitational
force induced by the mass of the crane or crane part shall be multiplied by the factor ϕ . Dependent upon
the gravitational load effect of the mass and load combination in question, the factor ϕ shall be calculated
in accordance with either Formula (1) or (2). For definitions of unfavourable and favourable load effects
see 4.3.3.”

In 4.2.2.2.1, replace the 3 paragraph with the following:
“The values of ϕ and ϕ shall be either calculated from the Formula (3) applying the specified stiffness

and hoist drive classes or determined either experimentally or by dynamic analysis. Where stiffness and
hoist drive classes are not applied, the true characteristics of the drive system and the elastic properties
of the overall load supporting system shall be taken into account.”
st
In 4.2.2.2.2, replace the 1 paragraph with the following:
“For the purposes of this document, cranes shall be assigned to a stiffness class ranging from HC1 to HC4
in accordance with the elastic properties of the crane and its support. The stiffness classes given in
Table 2 shall be selected on the basis of the characteristic vertical load displacement δ.”
st nd
In 4.2.2.2.2, replace the 1 sentence of the 2 paragraph with the following:
“The dynamic factor ϕ (and respectively ϕ for Load combination C1, see 4.2.4.1) shall be calculated

In 4.2.2.4, replace the 2 paragraph with the following:
“The dynamic actions shall be determined in one of the following methods:
— the factor ϕ is calculated using a simple single mass — spring — model for the crane as shown
below. The use of this simplified model is restricted to cranes whose actual dynamic behaviour
corresponds to that of the model.
— dynamic actions are determined by experiments or by calculation. Conditions for the travel surface
(gaps, steps) shall be specified.
— where available, a conventional value for the factor ϕ shall be taken from a European Standard for
the specific crane type, with specified conditions for the travel surface.”
st rd
In 4.2.2.4, replace the 1 sentence of the 3 paragraph with the following:
“The factor ϕ shall be calculated as follows:”
st
In 4.2.2.5, replace the 1 paragraph with the following:
“Loads induced in a crane by accelerations or decelerations caused by drive forces shall be calculated. A
rigid body kinetic model may be used. For this purpose, the hoist load shall be taken to be fixed at the top
of the jib or immediately below the trolley.”
