Class Code: 9534

Per NCCI's Scopes Code Description:

Code 9534 is applied to employers that perform mobile crane, hoisting, or rigging operations for others, provided that such operations are not otherwise classified in the Basic Manual.

When mobile crane, hoisting, or rigging operations are performed by an employer as a normal and incidental part of an employer’s construction or erection operations, these mobile crane, hoisting or rigging operations are assigned to the employer’s construction or erection operation that required this work. For example, hoisting or rigging operations performed by a concrete construction contractor as part of the concrete construction work are assigned to the concrete construction class that applies to the work for which the crane, hoisting, or rigging operation is performed.

When mobile crane, hoisting, or rigging operations are performed by an employer as a specialty service for others, this work is classified to Code 9534.

Code 9534 also applies to employers that perform mobile crane, hoisting, or rigging operations while performing other work—be it of a construction, erection or other nature—that does not ordinarily require mobile crane, hoisting, or rigging operations. For example, a contractor is hired to perform paving operations and provide mobile crane, hoisting, or rigging services at a particular job. Because paving work does not ordinarily require mobile crane, hoisting, or rigging operations, the appropriate paving code is assigned to the paving work and Code 9534 is assigned to the mobile crane, hoisting, or rigging operations.

This classification includes employers that rig steel derricks that are used in connection with the erection of steel structures. In connection with such work, particularly in tall buildings, it is sometimes necessary to move the derricks to higher levels as the construction progresses. If this work is undertaken by the steel erecting contractor, the payroll is assigned to the appropriate steel construction classification, but when it is undertaken by a specialist mobile crane, hoisting or rigging contractor, Code 9534 is assigned.

Rigging employers that move and hoist heavy articles from the ground to upper stories of buildings from the outside or vice versa by use of cranes with long booms or block and tackle, chain, rope or wire cable also fall within the scope of this classification, as well as employers that install chimes or bells in towers or similar structures.

The leasing or rental of mobile cranes and other hoisting devices without operators is assigned to Code 8107—Machinery Dealer NOC.

The following describes scaffolding operations and their proper classification assignments when the scaffolding installations are being performed by an employer for which no other classification such as a construction or erection classification as described above is more appropriate:

5057 Concrete or Cement—Distributing Towers Installation, Repair or Removal & Drivers
7219 Scaffolding—Delivery of Materials Only—No Installation, Repair, or Removal—All Employees & Drivers
9534 Scaffolding—Outrigger Scaffold Installation, Repair or Removal & Drivers
5057 Scaffolding—Scaffold Installation, Repair or Removal—Built Up From the Ground—Not Suspended or Swinging Type
5403 Scaffolding—Sidewalk Bridges Not Over One Story in Height
9534 Scaffolding—Suspended or Swinging Scaffold Installation, Repair or Removal & Drivers

Refer to Code 5403 for extra-territorial premium determination guidelines that apply to employers that have operations outside their headquarters’ state.

State Addendum
Massachusetts Code 9534 is applied to insureds that engage in mobile crane, hoisting or rigging operations for others provided such operations are not otherwise classified in the MA Manual.

Scaffolding: Contractors that erect, repair or remove scaffolds or cement distributing towers, sidewalk bridges or hod hoists, or construction elevators as an incidental part of their construction work to be separately rated. Such operations, when so performed, are to be included in the classification with which the work is associated. Refer to Codes 5403, 7219, and 9533 for other scaffolding and scaffolding-related operations conducted by specialist contractors.

Specialty concrete pumping operations conducted by specialty contractors are assigned by analogy to Class Code 9534—Mobile Crane and Hoisting Service Contractors—NOC—Including Yard Employees & Drivers. In accordance with Rule IV-F-2.—Business Not Described by Any Classification, as detailed in the MA Manual, the appropriate classification phraseology should read as follows: Concrete—Pumping—Specialty Contractor Only—Including Yard Employees & Drivers. It is important to note that any and all concrete pumping operations conducted by concrete construction crews remain properly assigned to the appropriate concrete construction classification(s) applicable to which the concrete is being pumped, not Code 9534.
