I was part of a crew that erected a link belt 250 ton conventional crane with 250 foot of boom and drove it about a 1/4 mile to hoist some HVAC units at intel in Phoenix AZ. so it's not unheard of.
Btw I have never seen a license for a crane operator.
CCO ( certified crane operator) maby that's what's beings called a license.
and a truck crane always lifts the most weight off the ass end.

You can call it a license, certificate, or whatever you'd like.

Cal OSHA requirement:

§5006.1. Mobile Crane and Tower Crane-Operator Qualifications and Certification.

(a) Qualifications. The employer shall only permit operators who have a valid certificate of competency (certificate) issued in accordance with this section by an Accredited Certifying Entity for the type of crane to be used to operate a crane covered by this section. Certificates shall be issued to operators who:


(1) Pass a physical examination conducted by a physician which at a minimum shall include the examination criteria specified in the Ameri- can Society of Mechanical Engineers (ASME) B30.5-2000 standard, Chapter 5-3.1.2(a)(1-5, 7, 8) or the U.S. Department of Transportation (US DOT) physical examination requirements contained in 49 CFR Sections 391.41 through 391.49.


(2) Pass a substance abuse test. The level of testing shall be consistent with the standard practice for the industry where the crane is in use and this test shall be conducted by a recognized laboratory service;


(3) Pass a written examination developed, validated, and administered in accordance with the Standards for Educational and Psychological Testing (Copyright 1999) published jointly by the Joint Committee of the American Educational Research Association, the American Psychological Association, and the National Council in Measurement in Education. The exam shall test knowledge and skills identified as necessary for safe crane operations and shall, at a minimum, include the following:


(A) operational characteristics and controls, including characteristic and performance questions appropriate to the crane type for which qualification is sought;


(B) emergency control skills, such as a response to fire, power line contact, loss of stability, or control malfunction;


(C) a demonstration of basic arithmetic skills necessary for crane operation and the ability to read and comprehend the crane manufacturer's operation and maintenance instruction materials, including load capacity information (load charts) for the crane for which certification is sought;


(D) knowledge of chapters 5-0 through 5-3 of The American Society of Mechanical Engineers (ASME) B30.5-2000 and B30.5a-2002 Addenda to the standard for mobile and locomotive cranes or chapters 4-0 through 4-3 of the ASME B30.4-1996 standard for portal, tower, and pedestal cranes or Chapter 3-3 of the ASME B 30.3-1996 standard for Construction Tower Cranes, depending on the type of crane(s) the operator intends to operate.


(4) Pass a "hands-on" examination to demonstrate proficiency in operating the specific type of crane, which at a minimum shall include pre-start and post-start inspection, maneuvering skills, shutdown, and securing procedures.

(b) Certification. Certificates shall be valid for a maximum of five (5) years. An Accredited Certifying Entity shall issue the certificate of competency to operators who successfully demonstrate the qualifications set forth in (a)(1)- (4) of this section.

(c) Accredited Certifying Entity. A certifying entity is any organization whose certification program is accredited by either the National Commission for Certifying Agencies (NCCA), or the American National Standards Institute (ANSI). ANSI accreditation shall be in accordance with the requirements of the ANSI, International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) 17024:2003(E), Conformity Assessment-General Requirements for Bodies Operating Certification of Persons, which is hereby incorporated by reference.

(d) Re-certification. Crane operators shall re-certify every five (5) years and shall be required to meet all of the qualifications set forth in subsection (a). Operators with at least one-thousand (1,000) hours of documented experience operating the specific type of crane for which re-certification is sought as covered by this section during the immediately preceding certification period and who meet the physical examination, substance abuse, and written examination requirements set forth in subsections (a)(1), (a)(2) and (a)(3) of this section shall not be required to take the "hands-on" examination specified in subsection (a)(4) to re-certify.

(e) Trainees may be authorized to operate mobile or tower cranes provided they are under the direct supervision of an operator possessing a valid certificate of competency for the type of crane operated by the trainee.

The term direct supervision means the supervising operator is in the immediate area of the trainee and within visual sighting distance and able to effectively communicate with the trainee. When performing direct supervision, the supervising operator shall have no other duties other than to observe the operation of the crane by the trainee.

(f) Effective Date. The requirements of Section 5006.1 shall become effective on June 1, 2005.

EXCEPTIONS TO SECTION 5006.1:


(1) Mobile cranes having a boom length of less than 25 feet or a maximum rated load capacity of less than 15,000 pounds.


(2) Operators of electric line trucks (digger derrick trucks) as defined in Section 2700 of the Electrical Safety Orders, and regulated by Section 2940.7 of the High Voltage Electrical Safety Orders. This exception does not include mobile truck cranes designed and built in accordance with the American Society of Mechanical Engineers (ASME) B30.5 standards.


(3) Marine terminal operations regulated by Article 14 of these Orders.

BTW, moving a large conventional rig with that much stick can be a really bad idea.

About a year before I went to work there, a local refinery had an incident when they were moving a large Lampson crane and did not do a ground compaction survey, and it gave out.
The crane went over and was cut up into scrap metal.
The stick barely missed an office trainer owned by union pacific resources and the guy sitting in the office, and fell across the Anaheim street bridge in Wilmington.

the crane was a sister to the one pictured below:

I had a crane tip over while trying to unload a 32 ton piece of machinery off my trailer at a Texas state corrections facility near Houston.
Inmates were operating it at the time. They got it up off my trailer and the plan was i drive out from under it.....almost made it. The back of the crane came off the ground and the machine hit the dirt and tipped back against my trailer. They ended up chaining the blade of a D9 cat crawler to the back of the crane and lowered the blade. Surprisingly no damage to my trailer.

I used to haul cranes (crane parts) to a lot of windmill sites.

Here's a tilt-up project I was the project manager back in '09. Big crane...

[URY914]

Hard to believe how big this thing is until you're next to it.

[sc_rufctr]

I wasn't sure were to put this...

Take my word for it. It's worth watching!

[unclebilly]

These are really cool. I have worked with these on multi well pad sites. Wherever they stop, they are setup. No out riggers, you can move with a load. Absolutely awesome.



Liebherr makes them too.

Thank God for hard hats.

The governement safety post mortem came to the conclusion that

High cranes were not stable enough on pontoons (No sjit sherlock)


And it all got screwed up because the City had not mandated a safety plan to the builder because they didn't think they were responsible for the safety.

The Builder didn't think it was the responsible party for the safety because they had subcontracted it to the crane company, and figured they would do the necessary.

the crane company had subcontracted the pontoons and figured those were stable enough and had pretty much calculated everything without any margins or consideration for basic things like wind and extra gear put on the deck of the pontoons.


If you ask me they are a bunch of morons because even a single crane on such a pontoon would be screwed for any kind of lateral movement and these morons did a double crane lift..

I'm not engineer but even I could have told em up front that **** would not work.

120 foot cranes on a floating 40 foot wide pontoon and they had not even told neigbours to clear the area?? They got very lucky nobody got injured or killed.

It works for new crane sales!

I have a confession. I would have loved to have been a crane operator/heavy equipment operator.

One of my neighbors owns a construction company that does a wide range of projects, including rock sea walls.

I hired him to stabilize a portion of my sea wall, add rock to help buttress the pressure treated wood. The rocks are in the 50 to 200 pound range and are stacked against the existing sea wall.

He has a really nice excavator to move the rocks. No grabber. I went out to check on his progress and he gives me the, "you want to give it a try" challenge.

Duh.

He then bets me $20 that I won't be able to pick up the rock with the bucket alone.

Easiest $20 bucks I have ever made. It was great!

What is interesting to me concerning all the videos is that the machines have a death rattle.

[Captain Ahab Jr]

Got a crane coming this week to lift my man cave roof steel beams into place and watching those video's are not doing my nerves any good

You are not alone.
Over drinks one night a friend and I put together plan to build a rent-by-the hour gravel pit. It would basically be a fantasy camp for wannabe heavy equipment operators. Get some of those big-ass dump trucks, some cranes, lots of bulldozers, backhoes, pan scrapers, etc, and charge per hour per machine to let people come in and play with them. It would have involved a lot of up front investment - more than we had - but I still think it would have worked.

Thought that would happen. Bunch of po'ed folks who lived there I expect. Just bad structural engineering. Who in their right mind would leave the bottom of the retaining wall above the grade?

Rented a smaller dozer/backhoe combo one weekend to level a chunk of the back yard so I had a flat pad for the kids jungle gym. #1 was 6 at the time and I let him sit with me and operate it. I live on a hill - yard slopes off in 2 directions and there was no way to install it without levelling.

He had more fun playing with that thing than he ever did on the playground after it was installed. I should have bought one of those instead...
