You can perform these periodic rigging inspections at any time of the year, but it is important to understand that users are required by ASME standards to perform a periodic inspection of all of your slings and hardware at least once a year.  

Bishop Lifting’s Services Department is available to come to your location and perform rigging inspection services. If you are interested in having Bishop’s Services department perform a periodic inspection on your rigging equipment contact them at 713-674-2266 or  Our team can help you develop an inspection schedule that best suits your company's needs.  Sometimes due to severity of use, periodic inspections can be required to be performed monthly, quarterly or annually. 

You are not required to use a third party for your periodic rigging inspections, and can use any of your employees that consider to be qualified based on experience and training. If you do not feel that you have any employees that are qualified, Bishop Lifting also offers training on rigging gear inspection. We offer many training options from 1 hour presentations all the way up to 2 day Rigging Inspector courses.

Hurricane Harvey Update

To our Customers, Suppliers and Friends,

Bishop Lifting Products and Delta Rigging & Tools have made it through Hurricane Harvey and the Houston, Angleton and Sulphur offices officially reopened for business on Thursday, August 31st. Hurricane Harvey hit Texas harder than expected, impacting millions, displacing hundreds of thousands. We prepared prior to the storm and remained in constant contact with our employees throughout the storm. All of our employees are safe, but many have water damage to their homes and cars, and few have lost everything.

Please contact us in regards to new or existing orders. Normal shipments and orders may take longer due to road conditions, freight delays and facility closures. Our other locations are helping with production to support our customers and utilizing inventory within our groups to minimize supply chain disruptions. Our team will do everything to help you meet your project deadlines.

Our parent company, SBP Holdings, set up a Go Fund Me account for employees affected by the storm. SBP will match employee contributions dollar for dollar over the next 14 days. 100% of contributions will go directly to SBP employees affected by the storm.  If you feel the need to donate, please contribute at: 

Thank you for your patience as our company returns to normal business. Our thoughts and prayers are with those who have been adversely affected.

Understanding Eye Bolts : 5 Factors to Consider

Eye boltsUnderstand Eye Bolts with a graphic of an eyebolt secured in beam with wire rope attached are one of the simplest and yet most often misused pieces of rigging equipment. There are several factors that must be considered when choosing and installing eye bolts. When eye bolts are used improperly, they can be damaged or broken leading to catastrophic accidents and injuries even when performing fairly basic lifts. For more information and help choosing the proper eye bolts or other rigging gear for your applications, please contact the Bishop Sales Team at 1-800-972-1041 or email them at


The first item to consider is whether you need a shouldered or non-shouldered eye bolt.

Non-shouldered eye bolts are only designed to be used for completely vertical lifts. If you are going to be lifting with your slings at an angle or with any kind of angular loading, you will need to use a shouldered eye bolt. Even when using a shouldered eye bolt, you must be sure that it is installed properly before you can apply any type of angular loading to it. If the shoulder is not completely flush so that it can function properly, the shouldered eye bolt can only be used for vertical lifts.  


eye bolt capacity chartAs the sling angle becomes smaller the tension being placed on the eye bolt increases while the eye bolts capacity diminishes drastically. It is very important that riggers understand this phenomenon completely in order to choose the proper eye bolt to make their lift safely.

For example, when using a Crosby eye bolt with a tight sling angle of 30 degrees the tension applied to the eye bolts during the lift will be two times the weight of the load being lifted. At the same time, the eye bolt itself has been reduced to 25% of it's original capacity. Some manufacturers do not recommend that you use their eye bolts at an angle below 45 degrees. If you do not account for both the increase in tension and the loss of capacity, the rigger will overload your eye bolt, and you are running the risk of damaging your equipment or dropping the load. 


The third factor to consider when selecting the correct eye bolt for a lift is to take the dimensions of the eye bolt eye into account. You want to make sure that all hardware and rigging equipment that will be attaching to the eye bolt will fit comfortably into the eye and be able to function properly.

For instance, if hooks are being attached to the eye bolts, you need to make sure that the hook fits comfortably through the eye. The load should rest in the bowl of the hook, and the hook should be able to align itself with the sling leg and not get kinked when tension is applied.  


Eye Bolt Install GraphicIt is also important to realize that eye bolts are not designed to rotate under load, and that in order to function properly you must apply tension across the plane of the eye of the eye bolt. The eye bolt must be aligned during installation and tightened to secure it against rotation during lifting. This means the rigger must install the plane of the eye bolt inline with the sling leg. This is done using shims from the manufacturer. It is not recommended that you use more than one shim to align the eye bolt with the sling leg. The manufacturer should be able to provide you with a shim of the proper thickness to turn the eye bolt to the proper alignment.



The final aspect to consider for proper application of eye bolts is the strength and thickness of the material that the eye bolt will be installed into. Even if the eye bolt you choose is the correct style and capacity, the material into which you are installing it must be capable of surviving the forces that will be applied during the lift. You will want to look at the drawings or consult with an engineer to make sure that the load can be safely lifted with the number of pick points you are planning to use and their locations on the load.

  • In an untapped through-hole, the nut shall be fully engaged. For vertical lifts where the shoulder isn't flush with the load, we recommend a second nut is used on the top of the load.
  • In a tapped blind hole, the effective thread length must be at least 1 1/2 times the bolt diameter when installed in steel. Having at least 2 times the bolt diameter is highly recommended.
  • In a tapped through-hole of less than one bolt diameter of thickness, a nut should be installed on the underside of the load and shall be fully engaged and tightened securely.  
  • For machinery eye bolts, minimum tap depth is the basic shank length plus 1/2 of the nominal eye bolt diameter.  


If an eye bolt is not the proper rigging hardware for the lift, there are two main alternatives to using eye bolts as your attachment points. 

Crosby Slide-Loc Lifting Points- Crosby's new SL 150M Slide-Loc has several features that set it apart from the standard eye bolt. It has a patent pending locking mechanism that slides to lock the bolt for installation, then slides back to be ready for lifting.

  • The bail can swivel 360 degrees to keep aligned with the sling line.
  • The Slide-Loc does not lose capacity at any sling angle.
  • It has a larger bail than the standard eye bolt to allow for easier connections with other hardware and slings. 

Swivel Hoist Rings- when they are installed and torqued properly swivel hoist rings are the most efficient and ideal option to use for lifting points. 

  • They have bail that can pivot 180 degrees and swivel 360 degrees.
  • Installed properly, swivel hoist rings do not lose capacity at any sling angle.
  • There are several different styles of swivel hoist ring that can match up to your particular application.
