Which trade erects jin poles for making heavy lifts and assembles cranes?

The correct answer is the rigger, as this trade is specifically trained in the use of equipment and techniques to lift and move heavy objects safely. Riggers are responsible for erecting jin poles, which are used to assist in making heavy lifts, and they play a crucial role in the setup and assembly of cranes. They understand load capacities, rigging equipment, and safe lifting practices to ensure that heavy materials and equipment can be moved without risk. Their expertise is vital for the safety and efficiency of heavy lifting operations on construction sites.

Other roles, such as heavy equipment operators, cranes technicians, and construction supervisors, may coordinate with or oversee operations involving heavy lifts, but they do not directly engage in the specialized tasks of erecting jin poles or assembling cranes to the same extent as riggers do.
