Master Rigger Jobs in Pennsylvania (NOW HIRING)

Summary

The Tower Crane Operator controls a fixed or traveling tower crane to lift, move and position heavy materials on high-rise and infrastructure projects. This position requires mastery of load charts, communication and precision controls, as well as strict adherence to safety protocols. Operators must be able to climb to the cab, work long shifts in varying weather and maintain focus and situational awareness at all times.

Key Responsibilities

• Pre-lift planning and inspection
  • Review lift requirements with the lift director and understand site conditions that could affect crane operations.
  • Perform daily pre-operational inspections (wire rope, brakes, limit devices, hooks and critical parts) and ensure all control functions respond properly.
  • Use the crane’s load rating charts and diagrams to confirm the correct configuration for the load, site and lift conditions.
• Operating the crane
  • Operate tower cranes using levers, wheels or foot pedals to lift and move materials according to a lift plan or schedule.
  • Communicate constantly with riggers, signal persons and workers on the ground via radio or standardized hand signals to coordinate lifts and ensure safe loading/unloading.
  • Track wind speed, load charts and crane performance during shifts; pause operations when wind speeds or site conditions exceed safe limits.
  • Coordinate with other operators on multi-crane jobs to avoid conflicts and collisions.
  • Operate smoothly and avoid any practices that might divert attention while at the controls.
• Safety and compliance
  • Refuse to operate if any load or part of the crane could enter the danger zone of energized power lines.
  • Follow OSHA and ASME procedures for lock-out/tag-out during maintenance or when repairs are required.
  • Set brakes, lock devices and land suspended loads when power fails or before leaving the crane unattended.
  • Keep records of materials moved, daily inspections and any minor repairs performed.
• Post-operational duties
  • Secure the crane at the end of each shift, including bringing the hook to the highest position, releasing slewing brakes as specified, restraining travel and disengaging the master control circuit.
  • Report any needed adjustments or repairs promptly to a designated person.
  • Conduct frequent inspections and arrange for periodic operator re-qualification (every five years or sooner if necessary).

Required Qualifications

• Education and Experience
  • High school diploma or equivalent.
  • Several years of construction experience, preferably with hoisting, rigging or heavy-equipment operations.
  • Completion of a formal tower crane training program and apprenticeship is highly preferred.
• Certification and Licensing
  • Must be at least 18 years old and meet OSHA’s 29?CFR?1926.1427 training and certification requirements.
  • Hold an accredited tower crane operator certification such as NCCCO CCO-Tower Crane; pass both written and practical exams and maintain re-certification every five years.
  • Comply with any state or local licensing requirements (e.g., New York’s Certificate of Competence, Washington state permits).
• Physical and Medical Requirements
  • Meet physical qualifications outlined by ASME B30.3: vision of at least 20/30 in one eye and 20/50 in the other, ability to distinguish colors, adequate hearing, and sufficient strength, endurance, agility and coordination.
  • Possess depth perception, manual dexterity and reaction time without tendencies to dizziness or seizures; pass substance-abuse screening and periodic physical exams.
  • Able to climb to the crane cab, work at height for long periods and tolerate extreme weather conditions.
• Skills and Competencies
  • Strong communication and teamwork skills for interacting with lift directors, riggers and other crew members.
  • Excellent coordination and steady hand-foot control to guide heavy loads precisely.
  • Mechanical aptitude to perform basic maintenance and identify equipment issues.
  • High situational awareness and problem-solving ability to adapt to changing site conditions.
  • Proficiency in reading and interpreting load charts, lift plans, safety documentation and manufacturer manuals.

Working Conditions Tower crane operators spend most of their shifts in an enclosed cab perched high above ground level. The role involves exposure to heat, cold, wind and other environmental factors. Operators often work long hours with limited breaks and may experience periods of isolation. Duties can be physically demanding and mentally taxing, requiring sustained concentration, alertness and responsiveness in all weather.

Training and Professional Development Employers typically expect completion of OSHA 10-Hour or 30-Hour Construction training, fall-protection and electrical-safety courses. Continuing education, periodic recertification and regular medical exams are required to maintain certification and compliance. Operators are encouraged to cross-train on other crane types and to stay current with emerging digital technologies (load-monitoring sensors, telematics, remote-control systems) to enhance lift accuracy and safety
