Tower crane operators perform one of the most technically demanding and safety-sensitive roles on any construction site. They are not simply machine handlers—they are central figures in the entire lifting operation. According to the Code of Practice for Safe Use of Tower Cranes (2011), the crane operator must control the crane in strict accordance with safety procedures, lifting plans, and regulatory requirements. The operator’s responsibilities begin before the first lift and continue until the crane is safely parked after operations conclude. The tower crane operator is required to hold a valid certificate recognized under Regulation 15A(1) of the FIU LALG. This certificate must be issued by an approved authority such as the Construction Industry Council or any body designated by the Commissioner for Labour. Only operators who have attained the age of 18 and have been adequately trained in operating the specific type of crane are permitted to carry out lifting operations.
A primary responsibility of the operator is to ensure that all crane movements comply with the approved lifting plan. Each movement—be it hoisting, slewing, or luffing—must be calculated, deliberate, and within the limits of the crane’s capacity. The operator must strictly observe the safe working load (SWL) at all times. As stated in the Code of Practice, exceeding SWL can cause tipping, structural failure, or fatal accidents. To help with this, the crane is fitted with an automatic safe load indicator (ASLI), and it is the operator’s responsibility to monitor this device continuously and stop the lift immediately if warnings are triggered.
Before beginning operations, the crane operator must conduct pre-use checks. This includes verifying that the brakes, limit switches, load indicators, warning systems, and control panels are functioning properly. As per Section 11.2 of the Code, daily checks and documentation should be performed to detect early signs of wear, malfunction, or unauthorized tampering. If any abnormality is found, the crane should not be operated until the issue is rectified by a competent maintenance technician.
During lifting operations, the operator must maintain strict focus on safety, situational awareness, and communication. One of the operator’s core responsibilities is to respond only to signals from one designated signaller or slinger at any given time, as noted in Section 5.2.1(c) of the Code. Confusion over signaling can result in miscommunication that leads to incorrect or dangerous maneuvers. The operator must fully understand hand signals as outlined in Table 1 of the Code and be proficient in interpreting voice or radio communication from the ground crew. This ensures synchronized action and reduces the chance of accidents.
Another critical responsibility is maintaining visual contact or clear lines of communication during every lift. If the load or working area is out of the operator’s sight, a signaller must be employed as per Regulation 15B(1) of the FIU LALG. The operator is responsible for confirming that this condition is met and that any delegated signaller is visible and recognizable, typically through high-visibility clothing or other means. The operator must halt operations if the signal is lost or unclear.
The operator also plays a role in load safety. They must ensure that all lifts are performed only after the load is confirmed to be properly rigged and secured by the slinger. Section 15.1 of the Code requires that all loads be safely secured and balanced before lifting. The operator must observe that slings are positioned correctly and lifting angles are appropriate to avoid shifting or slippage during the lift. In addition, sudden movements or abrupt changes in speed must be avoided to prevent dynamic loading effects that can exceed the crane’s rated capacity.
Weather monitoring is another area of responsibility. Section 12.6 of the Code explicitly states that lifting operations must be suspended during adverse weather conditions. The operator is expected to stop all lifts during high winds, heavy rain, poor visibility, or thunderstorms. Depending on the crane model and manufacturer’s specifications, wind speed thresholds may vary, but the general limit is around 65 km/h. The operator must be trained to interpret wind indicators or anemometers and report or react accordingly.
When the crane is not in use, the operator must ensure it is left in a safe state. Section 11.1 highlights the correct procedures when leaving a crane unattended, including releasing brakes, applying slew-locks (if applicable), raising hooks off the ground, and positioning the jib in weathervaning mode to align with the wind direction. Failure to secure the crane properly during idle periods can lead to uncontrolled movements or toppling, particularly in strong winds.
Documentation and recordkeeping are also within the operator’s scope. Any observations related to operational performance, anomalies during lifts, or malfunctions must be recorded in the crane’s logbook. This record becomes critical for maintenance planning, statutory inspections, and audits. Operators may also be required to sign off on checklists before and after each shift.
In addition to technical duties, the crane operator must uphold a high standard of teamwork and discipline. They are expected to participate in site briefings, safety drills, and coordination meetings. Their input is valuable when planning complex lifts, especially where visibility or space is restricted. The Code of Practice emphasizes the importance of the crane operator as a key member of the lifting team who must fully understand their responsibilities and communicate proactively with supervisors and signal crews.
In summary, the responsibilities of a tower crane operator extend far beyond operating a joystick or control panel. They encompass compliance with legal certification, adherence to lifting plans, real-time decision-making under variable conditions, precise coordination with the lifting team, and diligent equipment monitoring. The operator holds one of the most accountable positions on site, and their performance directly affects the safety and efficiency of every crane-assisted task. By following the detailed guidance from the Code of Practice, CIC Guidelines, and the FIU LALG regulations, operators can ensure that every lift is carried out safely, professionally, and within the full boundaries of compliance.
