TSS/BTF Frequently Asked Questions

As a TSS-certified operator, you may have noticed your new certification card and your record as shown on also lists CCO’s new “BTF” designation on it. You may wonder why. Here are some answers to questions you may have.

What does “BTF” stand for?

"BTF" stands for “Boom Trucks—Fixed Cab.” Having it on your card means you are certified to operate boom trucks with a fixed operator control station.

Why does my card list “BTF” on it?

The CCO Boom Truck—Fixed Cab Operator certification (BTF) is a subcategory of the Telescopic Boom—Fixed Cab certification (TSS) and was developed for operators who use these specific machines. Since crane operators holding TSS certification are also certified to run boom trucks—fixed cab by virtue of already being certified in TSS, all TSS-certified operators also have BTF listed on their cards when first certified or at recertification.

What do you mean by a “boom truck”?

A boom truck (also known as a commercial truck-mounted crane) is defined as a crane consisting of a rotating superstructure (center post or turntable), a fixed or telescopic boom, operating machinery, and one or more operator’s stations. It is mounted on a frame attached to a commercial truck chassis with a payload hauling capability and is equipped with its own power source. Its function is to lift, lower, and swing loads at various radii, requiring the use of outriggers/stabilizers.

What if my CCO card shows “TSS” but doesn’t currently show “BTF”; am I certified to run boom trucks—fixed cab?

Yes. You are still certified for BTF. If you need to show proof, you have two options:

  • Visit NCCCO’s Verify CCO Online (VCO) system at; it will show your BTF credential and is considered valid proof of certification.
  • Order an updated CCO card by visiting You will be charged a $25 fee.
