In Europe perhaps the most well known standard is EN General principles and requirements, which provides the cycle-based classification principles. Advertise with us Terms and conditions Site Map. For tower cranes a pre-standard prEN Follow these links to find other Standards similar to the 401-1 you are viewing.
Start Webshop Product catalog Product presentation. One of the key issues at the moment is the drive to put cycle-based 4301–1 of the components and mechanisms of the crane at the heart of the design and specification process, as is already the case for the crane structure.
It is important to us that you purchase the right document.
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:. Establishes a general classification of cranes based on the number of operating cycles to be carried out during the expected life of the crane and a load spectrum factor which represents a nominal state of loading.
Using these parts together with parts and these standards have now been changed from time to cycle-based classification.
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. In terms of new 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.
In summary Becker says that the harmonisation of the standards remains a work in progress but that the direction of travel is clear. It is also possible that a hoist with a large hook path in the average process condition average hoisting displacement will be stressed by less load cycles than estimated in the past.
You need to log in before adding standards to the monitoring service. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. This ensures that you are always up-to-date and saves you both time and money.
Compelo Ltd Registered Office: There have also been a range of ISO standards published which reflect the cycle based approach by connection to ISO If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password.
This methodology has now been laid down in the new version of ISO Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.

Harmonization of design standards is not an easy task but it is an important one. 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.
This means replacing the previous approach where components and mechanisms were assessed on a time-based classification system.

Webprint Printed and bound. General This document has been io by the committee, and judged to still be up to date. Together with the two parts for load actions 43011-1 2 and limit states and proof of competence of steel structure EN a cycle-based steel structure of a crane could be designed. In terms of international standards there has been less progress but the ball has certainly started rolling.
This service is not available if you are a URL user where you do not log in with an email address. For Europe the requirements of the Machinery Directive provide a catalyst to getting the European standards up to date.
