One of the men, Michael Fogel, 22, was taken to Essentia-Fargo Hospital in Fargo, N.D, where he died later in the day due to complications from his injuries. Christopher Mehlhaff, 27, was taken to the Avera McKennan Hospital in Sioux Falls, where he is said to be in stable condition.
It is speculated that the truck tipped over because it's outriggers were not properly used or deployed. This just goes to show why safety is so important! A 22 year old with his whole life ahead of him is now dead because proper safety wasn't followed. This could happen to anyone: Always remember that safety is first, second, and third!

Knuckle Boom cranes are great for all sorts of work. The compact and portable nature of a truck mounted crane is great for a variety of different tasks, but most commonly will be used for jobs that done where a full sized crane would not be ideal. Situations such as roadside construction, where a bigger crane really doesn't have the necessary space to swing it's boom around. These types of cranes also work well for dock work or work in a shipyard. Because they can be mounted on the back of a pick up truck this also increases their maneuverability and makes them more likely to be used in places where a load might have to be moved a longer distance. Because a truck is obviously more maneuverable than a tracked crane, they are often used in place. This is also an added benefit because they don't have to be transported on a trailer or special rig. They can just drive up to the job site, do the job, and drive off when done.

Every crane works differently to extend itself to its maximum length and to generate force, yet hydraulic cranes have become somewhat of the norm. Every hydraulic crane varies in its maximum lifting capacity, but the basic concept is quite simple.
Hydraulics all boil down to liquid moving into a confined space under pressure, and this liquid is always some sort of incompressible fluid. In hydraulic cranes, oil is the standard because it is most easily acquired and is inexpensive when compared to other alternatives.
So, first we have a piston pushing down onto the incompressible fluid, i.e. oil, which then conveys all of the original force generated to another piston. In accordance, the second piston is driven up to lift objects with ease. Simple. A hydraulic pump, either a variable-displacement pump or gear pump, is what creates all the pressure. Hydraulic cranes are generally equipped with a two-gear pump to pressurize the incompressible fluid (oil) when pushing down the throttle to give the pump more juice. If you need more pressure the engine must be running at full power to get the most force out of the machine.
This is the basic building block needed to operate a hydraulic crane.

Crane operators’ on construction sites and at shipping terminals control cranes to dig dirt, rip up steel or cement from the ground, and/or knock down structures during demolition. Getting a crane operation certification is smart because it is the highest paid equipment operating position within professions submersed in heavy construction. Most notably, these jobs are in high demand, and many companies are looking for experienced employees to get the job done right the first time.
The careers that are most likely to stem from becoming a certified boom crane operator will either be in the industries of road construction, building construction, oil, gas, mining, timber, working for local and state highways departments, or simply contracted utility work. Within each of these industries are multiple areas of expertise to pursue and various environments to explore which best suit your needs as a boom crane operator.
Part of the training and certification is learning to handle lattice boom crawler cranes, lattice boom truck cranes, small telescopic boom cranes, large telescopic boom cranes, swing-cab boom cranes, rough-terrain boom cranes, fixed-cab boom cranes, and fixed boom trucks. So, by becoming certified and meeting all of these qualifications the chance of finding employment is exponentially increased. Also, by having multiple specialties, you will increase your value to companies that want to hire you, and therefore also increase your worth and likely, your salary as well.

To begin apply for certification with the National Committee for the Certification of Crane Operators (NCCCO) and be sure you meet the minimum requirements, i.e. you must be substance free, in good physical and psychological condition, and be at least eighteen years of age. Once the application process is successful, there will be a variety of opportunities to explore, such as learning to operate a fixed cab hydraulic crane, swing cab, or become certified in both. This training will prepare you for the written exam—ninety multiple-choice questions—and the practical exam given in order to receive the NCCCO certification.
Following the written exam there will be a specialty exam(s) designed to certify an aspiring operator either in lattice boom crawler cranes, lattice boom truck cranes, small telescopic boom cranes, and large telescopic boom cranes. At least one of these exams must be passed to qualify for certification.
After this has been completed a practical exam will be conducted to display your working knowledge of the three different cranes types mentioned previously. If you pass, remember you must become re-certified every five years, and be able to meet all of the minimum requirements as well.

Boom cranes vary in the weights they are able to lift, and all boom cranes will come with a load chart. From the load chart, the operator will be able to derive the maximum weight capacity judging by the boom angle and that particular boom’s length. These variables all come into play depending on the size of the object being lifted and the overall structure of the boom crane itself.
Each boom crane will also advise operators on how much the particular crane is rated for—this is usually in tons. More weight is able to be lifted from the rear or front of the boom crane when stationary, but take caution if the boom must swing on either side of the crane. If this is not carefully watched and calculated the crane could tip over, so make sure you’ve accounted for the correct angle and boom length beforehand.
All in all, the majority of boom cranes are defined by the maximum weight the crane can lift at the lowest possible angle. Think of holding a weight straight out for as long as you can—it’s exhausting—until your shoulders begin to burn. This is very much the same idea behind finding the maximum weight of a crane.
