Lifting Accessories Information

 

Eyebolts

Eyebolts are one of the most commonly used lifting accessories, eye bolts are used in a wide variety of applications to provide lifting points on loads. Eyebolts can either have a purpose machined hole to suit the eyebolt or make use of a hole already machined into the product. It is common for lifting eyes once fitted to remain fitted to product where it becomes part of the load. However modern practice is to remove the eyebolts from the assembly and if necessary, plug the hole. If this is done it is important to note that the eye bolt then becomes a lifting accessory and under Lifting Operations and Lifting Equipment Regulations (LOLER) will require periodic inspection.

There are a wide range of eye bolts and equivalent eye nuts available and In numerous sizes, some examples of these are covered below:

 

 

Type

Standard

Details

Dynamo

BS 4278

The Dynamo eyebolt is commonly used in maintenance applications i.e. for lifting a motor

 

They are only designed for axial loading due to the small collar and ring cross section

Collard Eyebolt

BS 4278

The collard eye bolt is the general-purpose eyebolt used in a wide variety of applications

 

The large collar and ring cross section means this eyebolt is suited to both axial and angular loading, providing the eye is aligned to the direction of pull

 

The size of the eye is often a restriction and commonly required a shackle to aid lifting

Eyebolt with link

BS 4278

The Eyebolt with link is used where the eye of the collard eye bolt is to small to get a hook through

 

The compact eye and the link allow the eyebolt with link to be loaded in any direction providing more versatility

 

Collar eyebolt with Welded Link

BS 4278

Collar eyebolt with welded link serves the same purpose as the eyebolt with link allowing for loading in any direction

 

However, it only has the same lift capacity ratings as the standard collard eyebolt

DIN 580 Eye Bolt

DIN 580

The DIN 580 eye bolt are primarily intended as permanent attachments on equipment such as motors, control cabinets, gear boxes, etc. for their transport

 

If used as temporary attachments the next largest size should be selected from that specified.

 

Side pull or Shear Loading must be avoided, and load bearing capacity is only good to pull angled ≤45° 

Although Eyebolts are still heavily used, it is worth considering the use of modern lifting points, swivel links and hoist rings. These new generation of lifting points offer advanced engineering and increased load capacities over standard eyebolts. However, there is currently no standard for these types of lifting point but there are a few reputable manufactures that are used throughout industries today, these being RUD, Yoke, Crosby and Codipro. It’s worth considering the use of these as they offer additional strength and capacity benefits, but do have a higher cost.

Some examples and benefits of modern lifting points are covered below:

Finally, it is worth noting that LOLER Regulations state that all eyebolts and shackles (anything deemed a lifting accessory) used for lifting purposes are lifting accessories. They should therefore be subject to a thorough examination by a competent person at least every six months.

Testimonial

Lowe Stillages and Cages have worked for us for the past 6 years. We have always found the company to be proactive in their attitude, willing and able to solve problems quickly and provide us with a quality product that is right first time. Their level of professionalism is outstanding through all departments.

Joshua Cole – Head of Supply Chain 

We have engaged with Lowe Uk to design and make some bespoke stillages for holding and stacking hoses.

There service has been very helpful with full drawings and specifications. The stillages are now in use and performing really well.

We were able to tweak the design after the 1st batch were delivered and this was sorted very quickly.

The stillages have proved exceptionally successful and allows us to reduce manual handling of our goods and stack the goods which we have not been able to do in the past

There service, design and manufacturing has been very good.
