You need to log in before adding standards to the monitoring service. In terms of international standards there has been less progress but the ball has certainly started rolling.
Latest Features Features Archive. Jump to page content Accessibility. In Europe perhaps the most well known standard is EN General principles and requirements, which provides the cycle-based classification principles. Start Webshop Product catalog Product presentation. Vehicle jacks You may be interested in this related standard Hydraulic trolley jacks You may be interested in this related standard.
In summary Becker says that the harmonisation of the standards remains a work in progress but that the direction of travel is clear. The industry is currently using the time-based standards for this equipment but Becker hopes the new standards will be used from onwards. This had been the approach taken in the previous standard ISO For tower cranes a pre-standard prEN General This document has been re-assessed by the committee, and judged to still be up to date.
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. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. However he does concede that depending on the use changes might be necessary.
Another relevant standard which already use cycle-based classification by reference to EN for components of cranes is EN Webprint Printed and bound. 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:.

We recommend that you check the website of the publishers of the international document before making a purchase. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
Compelo Ltd Registered Office: 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. 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. Harmonization of design standards is not an isi task but it is an important one.
Pre-standards for sections covering the limit states and proof of competence of bearings prEN 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. He points to earlier standards such as the international ISO 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 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 – Cranes – Classification – Part 1: General
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. 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.
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. The European mobile crane standard EN This service is not available if you are a URL user where you do not log in with an email address.
The next step is for the subcommittees for mobile cranes, tower cranes, jib cranes and bridge and gantry cranes to revise their standards accordingly. The next important step then is to ensure that the standards reflect the changed approach.
But what is new is that standards covering components and mechanisms like hoists and their associated parts: Read more about subscriptions. In ido 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. Closing the loop 22 August 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 ido a load spectrum rather than the previous M-Class.
One of the key issues at the 4301–1 is the drive to put cycle-based classification 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. In parallel to this we have classifications for the product types of cranes in the ISO family given as parts like
