Who is ISNetworld?
ISNetworld is a web-based database for connecting clients with reliable prospective contractors. Maintaining safety metrics, insurance certificates, and quality and regulatory information on contractors and suppliers can often be a strain on internal resources. ISN streamlines these processes, saving time and improving safety standards. The result is lower incident rates and higher compliance numbers among ISN users.
Recently, CIA customers around the globe suggested that they needed faster access to regulatory information. In response, CIA took immediate action and subscribed to ISNetworld (ISN). As a result, CIA clients, that are also ISN subscribers, have immediate access to CIA’s key performance records and regulatory standards.
“ISN is a great tool that will help us build a more transparent relationship with our clients while continuing to ensure that Crane Institute remains to be a safe business partner,” says Jim Headley, President of Crane Institute of America.
CIA is proud to announce that as a result of this positive change, it has earned “A” ratings from two respected clients, Georgia Pacific, LLC and two International Paper facilities.
CIA is committed to maintaining the same high level of safety and transparency through ISN and other centralized databases. We invite all of our clients to join the more than 60,000 contractors and suppliers that have already moved to this more streamlined, automated business process.

A question posed to the Crane and Hoist Professionals group on LinkedIn asked if “Lugs” were required on underhung cranes. Most group members responded, “Yes,” because the ASME B30.11 or MH 27-1 requires it. This is not surprising because the text of many standards make them sound like they set requirements and well intended readers believe it. Let’s get technically correct:
• In the U.S., OSHA enforces the Code of Federal Regulations, for Safety and Health, with fines for non-compliance.
• In order for something to be “required” for safety and health, OSHA has to require it.
• ASME, ANSI, NFPA, NEC and other voluntary standards are only required to be followed if OSHA incorporates it.
• OSHA currently has no regulation covering underhung cranes.
• 29 CFR 1910.179 covers only top running bridge and gantry cranes.
• ASME B30.2, which is incorporated in part, covers top running cranes.
• Cranes only have to meet requirements that existed at the time of manufacture, grandfathering.
• Grandfathering and technical correctness exists until an accident.
• After an accident, OSHA can use the B30.11 lug requirement via the “general duty clause”.
• Lawyers have no rules.
• Lugs are not required on new or existing underhung cranes and employers cannot be required to install them.
• Employers must maintain a safe and healthful working environment.
• Employers can be held liable for not complying with “voluntary” standards.

Eyebolts can make a rigging job easier, but easier doesn’t mean safer.
An untrained rigger may incorrectly believe he can connect to an eyebolt by any means that work, but it is never that simple.
Eyebolts like all rigging gear, have requirements for safe use. Always follow manufacturer procedures when available, and remember these safety tips.
- When used for lifting, eyebolts must be made from forged alloy steel, not cast iron
- To connect to a load, eyebolts must be strong enough to withstand forces applied
- The shoulder of an eyebolt must be flush with mounting surface
- Shouldered eyebolts must be used when pulling at an angle
- Angular pull must be in the plane of the eye
- Eyebolts must have sufficient capacity; greatest when loaded in the vertical and reduced if pulled at an angle
In most cases, shortcuts are unsafe and not any more efficient. Shortcuts are more about not selecting the right equipment or improperly using the right equipment than they are about efficiency. Tools and equipment are designed for specific purpose, and equipment used for anything other than its intended purpose becomes dangerous.
Scissor lifts are intended to provide a safe platform for workers at a higher elevation. Standing on the mid-rail or the top rail, or working from a ladder stationed on a scaffolding platform is never safe.
A properly planned job will select a scissors lift with enough reach to do the job. Wood planked putlogs can safely be used to create a work platform deck for scaffolding, a walkway, or to bridge sections of scaffolding. Putlog end connections are curved to fit over the platform to secure it to a horizontal scaffolding tube, unlike the picture provided.

Darrell Rimmer Speeds Through Mobile Crane Operator Certification Exams and Passes!
Darrell Rimmer, an inspector and trainer with SIMMCO, a division of the Blurton Group, said, “I contribute my success to the formal training received from Crane Institute throughout the years, as well as my on-the-job experience.” He entered the industry in 1995. In 2003, he became a certified mobile crane inspector through Crane Institute. In 2006, he returned and earned both his Mobile Crane Operator Qualification and Mobile Crane Trainer Certification. He received his CIC Mobile Crane Operator Certification and CIC Practical Examiner Authorization in 2009. In addition to all of his mobile crane credentials, he is also a Qualified Rigger/Signalperson and a Certified Rigger/Signalperson Trainer.
Hats off to Mr. Rimmer, who recently renewed his CIC crane operator certification in a record time! Mr. Rimmer completed all six exams (General Knowledge, Telescoping Boom under 21 tons, Telescoping Boom 21-75 tons, Telescoping Boom over 75 tons, Lattice Crawler, and Lattice Carrier) in less than 2 ½ hours. The allotted time frame given is 6 ½ hours, though most complete the exams in 4 ½ to 5 hours.
Barbara Weedin, Open Enrollment Coordinator at Crane Institute, stated, “He has an incredible brain!” Mr. Rimmer modestly replied, “I’ve always struggled with math, but I’ve been trained through the Crane Institute, and I’ve been teaching others. Attending the class again was the review I needed to prepare for the exams.”
Cranes are intended to be set-up on firm, level ground. The rules change when cranes are placed on a ship or barge. Cranes mounted on unstabilized, non-jacked ships can create a major problem.
As a barge mounted crane lifts a load, the barge will push down into the water creating list or trim, causing the crane to become unlevel. Special load charts are available that compensate for up to 5°. Additional ballasts or counterweight are required to level the barge so as not to exceed the 5° allowance.
While the heavy lift vessel, BBC Coral, was commissioning her cranes, something went wrong. The two cranes mounted on the deck were being load tested by lifting a ballast pontoon. The pontoon dropped, half on the deck and half on the dock, ripping one crane from its pedestal.

This Flat Top Luffing Tower Crane can go from horizontal with a 55 meter radius to a minimum radius of three meters in only 90 seconds. The luffing speed is varied by the load sensing hydraulic luffing cylinder.
This near vertical feature is particularly beneficial on crowded job sites. With the jib in this vertical position, the out-of-service radius is less than 10 meters.
It has 12 tonnes lift capacity when dual reeved at 55 meters, and 6 tonnes capacity at 55 meters when single reeved.

Lifting massive vessels weighing hundreds of tons is no easy job.
Oil refineries and chemical plants use large, high pressure vessels in their refining process. To upright these vessels requires two lifting devices: a lead, hoist, or head crane and crane or tailing crane.
Both the lead and tailing cranes should have enough capacity to be able to lift the entire vessel on its own. To do the job, both cranes can be mobile cranes, or the lead crane can be a gantry while the tailing crane can be a mobile crane or hydraulic gantry. The process of lifting such a large, awkward load, requires both cranes to lift the horizontal vessel off the ground. The tailing crane moves the load so the lead crane can lift it vertical.

Killed – two workers in California when their personnel basket fell nearly 80 feet.
OSHA has strict requirements regarding hoisting personnel. If these requirements are followed, such accidents should cease to happen. The actual cause of this particular accident is still unknown to the public as the OSHA report will take time to surface. Early speculation is that the hook failed or the basket came off the hook.
Hooks used in personnel hoisting operations “must be capable of supporting, without failure, at least five times the maximum intended load applied” according to OSHA 29 CFR 1926.1431(g)(3). In simple terms the hook will withstand a 500% overload before it will fail at which point it will bend, not break. On a crane as large as the one used in the operation, the weight of the heaviest personnel basket and its contents should not come close to the yield point of the hook.
This begs the other question, how could the master link for the bridle supporting the basket come off the hook?
OSHA requires hooks used for hoisting personnel “must be of a type that can be closed and locked” (1926.1431(g)(1)(i)(A)). Closing the hook’s throat would prevent the basket from coming off the hook. Now let’s assume the hook was not equipped with a latch or the latch was defective.
- The weight of the basket should keep the master link in place in the bowl of the hook.
- For the basket to come off, an upward force would have to be placed on the master link. This could cause the master link to slip over the hook tip.
- An upward force could be generated by hitting an object with the personnel basket.
