History of the Association

The origins of the Lifting Equipment Engineers Association (LEEA) can be traced back to wartime Britain in 1943; a small group of competing companies came together to address what they perceived as a serious threat to their livelihoods. On 3rd June, nine people representing eight chain testing houses met at the Great Eastern Hotel, near Liverpool Street Station, and the idea to form an association to take on the might of government was conceived. Several weeks later, a draft set of rules and regulations was drawn up. During that process, a decision was made that, regardless of size, all members should be considered equal, both in terms of influence and financial contribution and the annual subscription was set at £4 and 4 shillings (£4.20).
The London Chain Testers Association was the name chosen by the founding members and was a clear reflection of the nature and location of the businesses involved. However, evidence shows that as this small group quickly made headway in negotiations with the government, attention turned to other areas where it was felt that co-operative action could be of mutual benefit. These included exploring the potential for pricing agreements, block insurance, the use of collective purchasing to secure more favourable deals from manufacturers, and adherence to British Standards to improve quality and consistency within the industry.By 1946, the association’s geographical boundaries expanded. Members were now actively sought from across the country, a move highlighted by a change of name to The Chain Testers Association of Great Britain.With the immediate concerns of a wartime economy behind them, the following decades of the 20th century can be seen as a series of landmarks that would ultimately establish the association as an authority on safe lifting and the industry’s foremost provider of training and qualifications for the test, examination and maintenance of overhead lifting equipment. Milestones in this period included:

  • The publication of the Chain Testers’ Handbook in 1953. Predominantly the work of Mr. C H A McCaully of W&E Moore, this brought together for the first time all the essential information required by the ‘man at the bench’ – the chain tester.
  • In 1959 it was followed by the examination scheme for lifting equipment engineers. In 1981, the Code of Practice for the Safe Use of Lifting Equipment (COPSULE) was launched.
  • In 1983, training courses were introduced to prepare students for exams that are now sat by several hundred candidates around the world every year.

Towards the end of the 20th century, important developments took place within the association’s infrastructure, and the nature of member companies changed to include a far wider range of activities. Notable events include the set-up of the organisation’s first independent office in 1977, and a third name change—to the Lifting Equipment Engineers Association in 1988.

With the introduction of the Lifting Operations and Lifting Equipment Regulations (LOLER) in 1998, LEEA’s training, qualifications and publications had to be fundamentally reworked to reflect this new legislation, and the association’s support and guidance became even more important to members obliged to comply with the requirements of the new legislation.

This legislative upheaval combined with the all-pervasive impact of globalisation, and an absence of sector-specific health and safety legislation—so, many companies who operated in these parts of the world began to adopt LOLER as best practice, which further enhanced the appeal of LEEA membership.

Since the turn of the century, LEEA’s development has reflected these trends and milestones have included:

Iran-Liftex-Exhibition-2018-Elevators-Industrial-Tehran-Iran

  • In 2006, The launch of the LiftEx trade show;
  • In 2007, the move to new headquarters and a purpose-built training centre, an ever increasing portfolio of practical courses to complement online distance learning provision;
  • In 2009, the introduction of the TEAM card registration and identity scheme for qualified engineers and technicians.

Perhaps the most striking is LEEA’s transformation into a truly international body. Regardless of where they are based, there is now no distinction between members – all are subject to the same technical audits prior to being granted full membership, with regular follow-up visits as long as they wish to remain part of the association. Dedicated local groups are now operating in the Middle East and Australia, and LEEA staff have become globetrotters, regularly meeting existing and potential members, as well as a host of other stakeholders, right across the world.

Lifting and Rigging Equipment: lifting with eye bolts

Lifting and Rigging Equipment: select the right eye bolt

There’s a lot of hardware to consider when researching lifting and rigging equipment. Links, hooks, swivels—today we’re talking eye bolts. Eye bolts are used to attach a securing eye to a structure, so ropes or slings can be pulled through.

Keep reading to discover how to select and use the right type of bolt, their dimensions and Working Load Limits.

Eye bolts are marked with thread size, not with their rated capacities. Make sure you select the correct eye bolt based on type and capacity for the lift you are conducting.

  • Use plain or regular eye bolts (non-shoulder) or ring bolts for vertical loading only. Angle loading on non-shoulder bolts will bend or break them.
  • Use shoulder eye bolts for vertical or angle loading. Be aware that lifting eye bolts at an angle reduces the safe load.
  • Follow the manufacturer’s recommended method for angle loading.

Lifting and Rigging Equipment: using eye bolts safely

  • Orient the eye bolt in line with the slings. If the load is applied sideways, the eye bolt may bend.
  • Pack washers between the shoulder and the load surface to ensure that the eye bolt firmly contacts the surface. Ensure that the nut is properly torqued.
  • Engage at least 90% of threads in a receiving hole when using shims or washers.
  • Attach only one sling leg to each eye bolt.

Direction of pull

 

  • Inspect and clean the eye bolt threads and the hole.
  • Screw the eye bolt on all the way down and properly seat.
  • Ensure the tapped hole for a screw eye bolt (body bolts) has a minimum depth of 1 1/2 times the bolt diameter.
  • Install the shoulder at right angles to the axis of the hole. The shoulder should be in full contact with the surface of the object being lifted.
  • Use a spreader bar with regular (non-shoulder) eye bolts to keep the lift angle at 90° to the horizontal.
    • Use eye bolts at a horizontal angle greater than 45°. Sling strength at 45° is 71% of vertical sling capacity. Eye bolt strength at 45° horizontal angle drops down to 30% of vertical lifting capacity.
    • Use a swivel hoist ring for angled lifts. The swivel hoist ring will adjust to any sling angle by rotating around the bolt and the hoisting eye pivots 180°.

 

Lifting and Rigging Equipment: eye bolt techniques to avoid

improper-eye-bolt-use-lifting-equipment
Don’t run your sling through an eye bolt!
  • Do not run a sling through a pair of eye bolts: this reduces the effective angle of lift and puts more strain on the rigging.
  • Do not force the slings through eye bolts. This force may alter the load and the angle of loading.
  • Do not use eye bolts that have been ground, machined or stamped.
  • Do not use bars, grips or wrenches to tighten eye bolts.
  • Do not paint an eye bolt. The paint could cover up flaws.
  • Do not force hooks or other fittings into the eye; they must fit freely.
  • Do not shock load eye bolts.
  • Do not use a single eye bolt to lift a load that is free to rotate.
  • Do not use eye bolts that have worn threads or other flaws.
  • Do not insert the point of a hook in an eye bolt. Use a shackle.
  • Do not use non-shouldered bolts to lift horizontally—non-shouldered bolts should only be used to lift vertically.

  • Ultimate Load is 5 times the WLL. Maximum proof-load is 2 times the WLL.
Definitions

* Ultimate Load: The load at which the item being tested fails or no longer supports the load.

** Working Load Limit: The maximum combined static and dynamic load in pounds or tonnes should be applied to the product in service, even when the product is new, and when the product is uniformly applied in direct tension to the product.

*** Maximum Proof-Load: The maximum tensile force that can be applied to a bolt without deformation. This is usually between 85-95% of the yield strength.
