Hear from Jim Headley, CEO of Crane Institute of America, and Steve Fryer, NCSG’s Manager of Training on how they deploy simulators to assess and build real skills. Learn how these industry leaders applied objective and consistent learning methodologies with simulation-based training.
Simulation-training gets proven results – faster time to competency, skilled and safe operators, and more effective assessment. If you are interested in improving your training methodologies and measuring operator skills then this is a must-attend event!

Self-erecting tower cranes run the risk of tipping much like mobile cranes.
In some cases, self-erecting tower cranes are replacing mobile cranes because of their efficiency in travel and set-up. Self-erector set-up is similar to mobile crane set-up. Both require firm, level ground with extended outriggers or stabilizers. Counterweights must be installed per the manufacturer’s specification like most modern mobile cranes.
Unlike traditional tower cranes, which experience structural failure if overloaded, self-erectors are more likely to tip over. However, like mobile cranes, self-erectors are difficult to turn over because of their large structural design factors and required load chart safety margins.
Our Tower Crane Operator & Inspector covers hammerhead, luffing, and self-erecting tower cranes.

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.

Crane Institute Announces Plans for New Programs
August 4, 2014 (Sanford, Fla.) — More than 15 Training Specialists for Crane Institute of America recently met at Crane Institute’s headquarters for Annual In-Service Training in order to provide the best possible customer experience. All Training Specialists are certified and qualified through Crane Institute of America. The training session includes refreshers on the latest equipment and changes to regulations.
The training meeting included a conference call with Crane Institute Certification’s (CIC) Executive Director, Debbie Dickinson, to learn more about OSHA’s proposed delay of crane operator certification requirements. CIC submitted viable solutions to OSHA with the intent to satisfy the agency’s concerns over employer responsibility to qualify workers. Subsequently, an industry coalition, including CIC, was formed to represent the interests of the crane industry.
In other news, Dickinson reported three states have or will adopt language requiring certification or licensing by crane type and size. These include California, Washington, and New York. Finally, she announced the launch of two new CIC certifications; Service Mechanics Truck and Lift Director.
New Programs and Resources
Crane Institute of America announced to its Training Specialists new programs currently in development. Two new training courses for people involved in crane management are set to be released in Fall 2014. The new Lift Director and Lift Planner courses are designed to prepare students for the CIC Lift Director Certification Exams. In addition, look for a course for Assembly/Disassembly Director in 2015.
Also new is a metric version of the handbook, Rigging, available for purchase on Crane Institute’s online store this September.
Crane Institute now has a public LinkedIn group, called Crane and Rigging, for those in the industry with related questions. Crane Institute Training Specialists offer a credible source...
A structure resembling something from a science fiction movie is being built in Chernobyl, Ukraine. This impressive arch is being assembled to cover the remains of the Chernobyl power plant’s reactor number 4 in the continued effort to contain and cleanse the area from a catastrophic disaster over 28 years ago.
Four tower cranes and several mobile cranes are assembling sections of the arch on-site. Once assembled, overhead cranes will be mounted to the under belly of the arch to be used later in the dismantling of the decaying nuclear power plant. The completed massive structure will be pushed on Teflon pads to encompass the existing plant.
Once in place, the arch will serve as a tomb to encase whatever radio active material is still emitting from the plant. It will limit human exposure now and for future generations.
Collisions are always a potential hazard when there are more than one tower crane on the job site with overlapping coverage. There are anti-collision devices that will attempt to prevent accidents from occurring, but standard operational safety should be the primary source in avoiding collisions.
It is believed that this collision occurred because the Jost hydraulic crane was out of service with its jib raised in the path of the flat-top saddle jib tower crane. The operator sustained head injuries in the collision.
Whether it is a quick in and out or a complete construction project, self-erecting tower cranes are a serious option filling a niche between telescoping and lattice boom cranes. Because they are efficient to transport and erect easily, they compete with lattice boom cranes for reach when heavy capacity is not required.
In Christopher Columbus’ day, sailors loaded sizable cargo onto their ships using simple blocks and tackle. This system used leverage to hoist heavy loads high into the air and onto the ship. Although the same basic physics apply today, technology has greatly advanced. Many modern cargo ships come equipped with full-size hydraulic cranes built into the deck. In essence, the same lever system developed in ancient Greece is still in use, but instead of a man using his own strength, we use the strength of a machine. As cranes get larger and loads get heavier, it is more important than ever to get safety training for your personnel. Crane Institute offers courses for Operators and Inspectors in: Mobile Cranes, Overhead Cranes, and Tower Cranes.
Have a safe and Happy Columbus Day!
