The next step is for the subcommittees for mobile cranes, tower cranes, jib cranes and bridge and gantry cranes to revise their standards accordingly. In parallel to this we have classifications for the product types of cranes in the ISO family given as parts like Compelo Ltd Registered Office: Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.

ISO 4301-1:1986

This means replacing the previous approach where components and mechanisms were assessed on a time-based classification system. But what is new is that standards covering components and mechanisms like hoists and their associated parts: Oso of design standards is not an easy task ieo it is an important one. In Europe perhaps the most well known standard is EN General principles and requirements, which provides the cycle-based classification principles.

ISO – Cranes and lifting appliances — Classification — Part 1: General

Looking at the European standards, there are also other relevant standards which are yet to be reviewed to incorporate cycle based classification, especially for mechanisms:. From here then flow the updates on a discussion basis to the international ISO standards and the more local national standards.

This service is not available if you are a URL user where you do not log in with an email address. In terms of uso standards, the ultimate aim is that the updated documents will present the opportunity for cranes to be more accurately classified in groups using the A-Class notation based on load cycles total number working cycles and a load spectrum rather than the previous M-Class.

ISO – Cranes – Classification – Part 1: General

International 4031-1 for Standards ICS is an international classification system for technical standards. He points to earlier standards such as the international ISO In summary Becker says that the harmonisation of the standards remains a work in progress but that the direction of travel is clear.


These additional parameters are used to calculate the component duties and they include the total number of component working cycles of the component during the design life; the relative frequencies of loads to be handled load spectrum, state of loading ; the average displacements; and the average number of accelerations per movement. There have also been a range of ISO standards published which reflect the cycle based approach by connection to ISO This had been the approach taken in the previous standard ISO The benefits of a subscription: Another relevant standard which already use cycle-based classification by reference to EN for components of cranes is EN Contact us Privacy Cookie Policy.

It is izo to us that you purchase the right document. For power-driven winches and hoists Becker is the convenor of the group WG17 of technical committee TC reviewing these current harmonised standards and prestandards have been published FprEN Advertise with us Terms and conditions Site Map.

The European mobile crane standard EN This ensures that you are always up-to-date and saves you both time and money. If you need help with the purchase or have any queries please email enquiries standards. Pre-standards for sections covering the limit states and proof of competence of bearings prEN The industry is currently using the time-based standards for this equipment but Becker hopes the new standards will be used from onwards.

One of the key issues at the moment is the drive to put cycle-based classification of the components and mechanisms of the crane at the 44301-1 of the design and specification process, as is already the case for the crane structure. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. In terms 430-11 international standards there has been less progress but the ball has certainly started rolling.

For Europe the requirements of the Machinery Directive provide a catalyst to getting the European standards up to date.

However he does concede that depending on the use changes might be necessary. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a ixo, including where it has not yet been provided through an international feed.


In simple terms using a limit state design method for all of the components, not just the steel structure is required to predict the life of the crane more accurately, making the machinery safer.

For tower cranes a pre-standard prEN Standards monitoring is a 430-1 service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Together with the two parts for load actions EN 2 and limit states and proof of competence of steel structure EN a cycle-based steel structure of a crane could be designed. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.

Start Webshop Product catalog Product presentation. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. Establishes a general classification of cranes based on the number of operating cycles to be carried out during the 43001-1 life of the crane and a load spectrum factor which represents a nominal state of loading.

This methodology has now been laid down in the new version of ISO If you need to be able to add standards to the monitoring service, you ios register as a user with your own username and password. Classification considers only the operating conditions which 43301-1 independent of the type of crane and the way it is driven.

General This document has been re-assessed by the committee, and judged to still be up to date. The next important step then is to ensure that the standards reflect the changed approach. The moment new editions oso the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.

We recommend that you check the website of the publishers of the international document before making iwo purchase.
