NCCCO Certification Designation Codes

Given the wide range of NCCCO certifications offered, NCCCO frequently uses abbreviations (or “codes”) for certification designations. You’ll find these codes on your certification card(s), in VerifyCCO, in the myNCCCO app, on the NCCCO website, and elsewhere.

The table below spells out what each code stands for; links are provided for those codes that require further explanation:

Testing in Languages Other Than English

The OSHA crane rule allows for certification tests to be administered in any language the operator candidate understands, as long as the certification card indicates the language the tests were given in. The employer must also provide the operator with operating manuals written in the language of the certification, and all onsite communication has to be understood by all parties. Currently NCCCO is offering Mobile Crane Operator written exams in Spanish; certificants who have tested in Spanish will have “-SP” appended to the applicable certification codes (i.e., LBC-SP, TLL-SP, TSS-SP).

Boom Truck—Fixed Cab

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. For more information, see the Boom Truck Operator certification overview page.

Service Truck Crane

The CCO Service Truck Crane Operator certification (STC) is a subcategory of the Telescopic Boom—Fixed Cab certification (TSS) and was developed for operators who use these smaller machines. Since crane operators holding TSS certification are also certified to run service truck cranes by virtue of already being certified in TSS, all TSS-certified operators also have STC listed on their cards when first certified or at recertification. For more information, see the Service Truck Crane Operator certification overview page.

Restricted Certifications

Certain CCO certifications may be issued with a restriction on the certification limiting the scope of the certification. These restrictions are noted on the certification card with either “-R” (Restricted) or “-SB” (Short Boom Restricted), and the detailed explanation of the restriction is provided below:

Certification Code
Certification Designation Name Restriction
TLL-R
Telescopic Boom Cranes—Swing Cab – Restricted
  • Maximum boom length of 37 ft.
  • Not equipped with attachments or jibs
  • Basic load chart
Certificants with this designation are limited to operating telescopic boom cranes with a rotating operator station (controls move as the boom rotates) with a maximum boom length of 37 ft. The crane may not be equipped with any attachments or jibs/extensions (operation must be from the main boom only). The crane must be outfitted with a basic load chart. As an example, see the QMC Load Chart here.
TSS-R
Telescopic Boom Cranes—Fixed Cab – Restricted
  • Maximum boom length of 37 ft.
  • Not equipped with attachments or jibs
  • Basic load chart
Certificants with this designation are limited to operating telescopic boom cranes with a fixed operator station (controls are fixed and do not move as the boom rotates) with a maximum boom length of 37 ft. The crane may not be equipped with any attachments or jibs/extensions (operation must be from the main boom only). The crane must be outfitted with a basic load chart. As an example, see the QMC Load Chart here.
LBC-SB
LBT-SB
TSS-SB
BTF-SB
Short Boom Restriction

Candidates passing NCCCO practical exams on cranes not meeting minimum standardized boom configurations will have “Short Boom Restriction” added to their certification card for the crane designations for which they receive certification; for example, “Telescopic Boom Crane—Fixed Cab (Short Boom Restriction).”

 

Rigger Level I & Rigger Level II

Rigger certification covers the following types of rigging:

  • Synthetic slings
  • Chain slings
  • Wire rope slings
  • Metal mesh slings
  • Rigging hardware

For more information, see the Rigger programs certification overview page

Signalperson

Signalperson certification covers the following types of signaling:

  • Hand signals
  • Voice/radio signals

For more information, see the Signalperson program certification overview page

Telecommunications Tower Rigger Level I

The CCO Telecommunications Tower Rigger Level I certification (TTR-I) is a restricted version of the CCO Rigger Level I certification. The Telecommunications Tower Rigger Level I was developed specifically for riggers in the wireless telecommunications industry. Tower Riggers are identified by their unique knowledge of communication structures (e.g., self-support towers, guy towers, monopoles, etc.) For more information, see the Telecommunications Tower Rigger Level I program overview page.
