Core Responsibilities

Primary Functions

Expertly operate tower cranes (including luffing jib, hammerhead, and self-erecting models) to lift, move, position, and place a wide variety of materials and equipment, such as steel beams, concrete buckets, formwork, and pre-fabricated panels.
Meticulously interpret and follow hand signals, voice commands, and radio communications from qualified riggers, signalpersons, and spotters to ensure precise and safe load placement.
Conduct thorough pre-shift and post-shift inspections of the crane's mechanical, electrical, and structural components in accordance with manufacturer specifications and company safety protocols.
Accurately calculate crane capacities by interpreting load charts and factoring in variables like load weight, lift radius, boom angle, and weather conditions to prevent overloading.
Maintain a detailed and accurate daily logbook of all crane operations, including lift details, inspection findings, and any maintenance performed, for compliance and record-keeping purposes.
Communicate constantly and clearly with the ground crew, site supervisors, and other equipment operators to coordinate activities and ensure a safe, efficient workflow across the entire job site.
Execute complex and "blind" lifts, where the load is not in the operator's direct line of sight, relying entirely on instruments and communication from the ground crew.
Proactively identify and report any potential hazards, equipment malfunctions, or unsafe conditions to the site supervisor immediately to mitigate risks.
Perform routine and preventative maintenance on the crane, including lubrication of moving parts, checking fluid levels, and cleaning the cab and machine components.
Secure the crane at the end of each shift or during high-wind events, ensuring it is properly shut down, parked, and allowed to "weather-vane" as required.
Adhere strictly to all applicable federal (OSHA), state, and local safety regulations, as well as company-specific safety policies and procedures for crane operation.
Participate in the assembly and dismantling (erection and teardown) of the tower crane under the supervision of a qualified erection director.
Systematically check and verify that all rigging, shackles, and lift-assisting devices are appropriate for the load and in good condition before commencing any lift.
Manage the movement of loads over and around active personnel, existing structures, and public spaces, demonstrating exceptional spatial awareness and judgment.
Operate the crane with smooth, controlled movements to minimize load swing and ensure the stability of the materials being hoisted.

Secondary Functions

Assist in the planning of critical lifts by providing expert input on crane capabilities, positioning, and potential operational challenges.
Mentor and provide guidance to apprentice operators, riggers, and signalpersons, sharing knowledge of best practices and safety procedures.
Maintain a clean and organized operator's cab, ensuring all controls, gauges, and communication devices are in good working order.
Monitor weather forecasts and on-site anemometer readings, making informed decisions to suspend operations when wind speeds or other conditions exceed safe limits.
Participate in daily job site safety briefings (toolbox talks) and contribute to a culture of safety awareness among the entire project team.
Respond calmly and effectively to emergency situations, such as power loss or mechanical failure, by following established emergency procedures.
Ensure the crane's swing radius is properly barricaded and marked to prevent unauthorized personnel or equipment from entering the danger zone.

Required Skills & Competencies

Hard Skills (Technical)

Valid NCCCO Tower Crane Operator (TWR) certification or an equivalent, recognized state or federal license.
Proficiency in reading and interpreting complex load charts for various crane configurations and models.

Ability to perform basic mechanical troubleshooting and assist with preventative maintenance on crane systems.
Skilled in using multi-channel two-way radio systems for clear and concise communication in a noisy environment.
Thorough understanding of standard rigging practices and the ability to visually inspect rigging components for safety and compliance.
Competency in operating modern crane computer systems and load moment indicators (LMIs).

Soft Skills

Exceptional hand-eye-foot coordination and fine motor skills for precise, smooth control.
Superior spatial awareness, depth perception, and judgment of distances, particularly when working at extreme heights.
Unwavering attention to detail and a methodical approach to safety checks and operational procedures.
Strong communication and interpersonal skills to coordinate effectively and build trust with the ground crew.
Ability to remain calm, focused, and make sound, split-second decisions under pressure.
Excellent physical fitness, comfort with working at significant heights, and the ability to climb the crane mast daily.
A high degree of personal responsibility, reliability, and a steadfast commitment to a safety-first culture.
