Lifting Equipment Safety Regulations | Vietmani Solutions

In the context of strong industrialisation and infrastructure development, lifting equipment systems are the core material handling devices in factories, ports, and construction sites. However, the inherently dynamic nature of heavy lifting processes always carries the risk of catastrophic accidents. To eliminate these risks, lifting equipment safety regulations have been issued. These are not only foundational technical standards but also mandatory legal obligations for every enterprise. In this article, Vietmani will comprehensively analyse the regulatory system (QCVN, TCVN) and the practical inspection process, helping managers and HSE specialists establish a robust protective barrier for the industrial work environment.

Safety Regulations FOR OPERATORS of Lifting Equipment

No matter how advanced the overload protection technologies integrated into machinery systems are, they cannot eliminate the element of human error. Among all occupational safety risks, subjective operational errors are often the leading cause of the most serious incidents. Therefore, the Ministry of Labour - Invalids and Social Affairs has established an extremely strict legal and "technical barrier" for personnel directly operating lifting equipment.

Health and Age Standards

The operation of heavy load lifting equipment requires intense concentration and sharp reflexes. Therefore, operators must meet strict standards:

• Age and legal capacity: Must be at least 18 years old and have full civil act capacity.
• In-depth health screening: Must undergo specialised health examinations for heavy, toxic, and dangerous occupational categories. Medical records must prove that the worker does not suffer from diseases that pose a risk of sudden loss of control (cardiovascular, neurological), and has standard vision and hearing. In particular, for tower crane operators, the psychological factor of not being afraid of heights is a mandatory criterion.

Professional and Safety Training Requirements

To be allowed to enter the cabin or operate on the control panel, personnel must possess both of the following mandatory certificates:

• Vocational skills certificate: Must be formally trained and possess a primary vocational diploma or certificate corresponding to the exact type of lifting machine being operated (e.g., overhead crane operation certificate, wheel crane driving certificate). Cross-operating equipment without cross-training is strictly prohibited.
• Group 3 Occupational Safety Card: According to Decree 44/2016/ND-CP, operating lifting equipment belongs to the group of jobs with strictly required occupational safety. Operators must participate in an intensive training course, pass an exam, and be issued a Group 3 Occupational Safety Card. This card must be renewed periodically and always carried during working shifts.

On-site Discipline and the Right to Refuse Work

The operator is not just a machine worker but also the final safety "checkpoint".

• Lifestyle discipline: The presence of alcohol, stimulants, or nerve-suppressing sedatives in the operator's circulatory system is strictly prohibited before and during working shifts.
• The right to suspend work: The operator is legally protected in their right to refuse to operate the equipment if they assess that the actual conditions do not meet safety standards (e.g., detecting excessively frayed/broken cables, slipping winch brakes, equipment with expired inspections, or unclear signalman commands). This suspension decision must be immediately reported to the Health, Safety, and Environment (HSE) Supervisor for timely technical intervention.

The 3 Golden Phases in Lifting Equipment Safety Regulations

A perfect inspection system or highly qualified personnel will only be effective when bound together by standard operating procedures on-site. The process of lifting goods is not a series of improvised actions, but a closed mechanical procedure. This process is divided into 3 phases:

Safety Rules BEFORE Operation

Catastrophic incidents rarely occur suddenly; they are usually the result of ignoring small warning signs. Therefore, reviewing the static state of the equipment before starting is crucial:

• Evaluating load-bearing mechanisms: The operator must directly inspect, visually and with measuring equipment, the condition of the steel wire rope (no excessive fraying/breaking/stretching beyond allowable limits), the lifting hook (no cracks, the safety latch on the hook neck must work properly), and the pulley/drum system.
• Checking electromechanical limits (No-load test): It is mandatory to start and run the machine without a load to evaluate the sensitivity of the braking systems (hoist brake, slewing brake), limit switches, and overload protection mechanisms.
• Evaluating spatial variables: Set up barricades and warning signs around the crane's operating radius to create an Exclusion Zone. Simultaneously, measure the actual wind speed at the site and check for the presence of overhead power lines to compare against mandatory safe distances.

Safety Rules DURING Operation

Once the load has left the ground, the machine begins to be subjected to dynamics and inertial forces. At this point, any incorrect manipulation can disrupt the force balance state:

• Controlling acceleration and trajectory: Jerky movements (sudden lifting/lowering) that cause shock stress to the steel structure are strictly prohibited. Do not use the lifting hook to drag loads on the ground, pull diagonally, or uproot objects buried/frozen in the ground, as this creates transverse shear forces that can destroy the crane.
• Adhere to the absolute "3 NOs" rule:

1. No using cargo lifting equipment to lift people (except for specialised equipment like aerial work platforms, boom lifts).
2. No moving suspended loads over the heads of personnel working below.
3. No lifting operations when the exact weight of the object has not been determined or when the load has not been properly tied and slung at its centre of gravity by professional Riggers.

• Signal discipline: The crane operator is only allowed to act based on the commands of a single Signalman via walkie-talkie or an internationally standardised hand signal system, avoiding information interference.

Safety Rules AFTER Operation

The safety procedure truly ends only when the equipment is brought back to a safe resting state, eliminating potential energies that could cause harm when unsupervised:

• Unloading and retracting mechanisms: The load must be lowered onto solid supports on the ground; absolutely no loads should be left suspended in the air when leaving the cabin. Retract the entire boom, pull the lifting hook up to a safe position (close to the pulley) to avoid swinging and collisions caused by the wind.
• Locking energy systems: Move the equipment to the designated parking area. Engage all mechanical safety latches, apply the handbrake, turn off the main electrical circuit breaker, and remove the cabin key to prevent unauthorised use.
• Updating machine log data: Fully record the details in the "Machine Shift Logbook". Specifically, if any unusual noises, brake delays, or hydraulic fluid leaks are detected during operation, the operator must immediately note them down and report directly to the Maintenance department for intervention before the next working shift.

MANDATORY Cases for Stopping Lifting Equipment Operations

In industrial risk management, project progress must never be prioritised over safety. According to current lifting equipment safety regulations, there are "red lines" that, when crossed, require the operator and safety supervisor to immediately activate the Emergency Stop procedure to preserve lives and property. Below are 3 groups of causes requiring immediate operation suspension:

Aerodynamic Factors

Lifting equipment, especially tower cranes or wheeled cranes with long booms, is highly sensitive to wind pressure and natural phenomena. Stopping the crane is mandatory when:

• Wind exceeds allowable limits: Wind speed at the site exceeds level 5 (or level 6, depending on the manufacturer's specified limits stated in the machine logbook). Aerodynamic drag from strong winds can twist the boom, break cables, or overturn the crane.
• Restricted visibility: Dense fog, heavy rain, or lack of light prevents the operator from clearly seeing the load or losing visual contact with the signalman.
• Thunderstorm warnings: During lightning, a crane with its towering steel structure becomes a giant lightning rod. It is mandatory to lower the load, retract the boom, and evacuate personnel from the operating radius.

Red Alerts from Mechanical and Hydraulic Systems

Any deviation exceeding technical tolerances is a precursor to a collapse. Operations must stop immediately if the following are detected:

• Signs of destruction on steel wire ropes and load-bearing equipment: The number of frayed/broken cable strands within one lay length exceeds TCVN regulations; the lifting hook is cracked, geometrically deformed, or the anti-slip latch (safety tongue) at the hook mouth is broken.
• Braking system failures: The hoist brake, travel brake, or slewing brake shows signs of slipping, locking up, or making unusual friction noises. The load free-falls even after releasing the control joystick.
• Energy leaks: Hydraulic hoses burst, pressure leaks at lifting cylinders; or the electrical control system flickers, sparks, or leaks electricity to the machine casing.
• Steel structure deformation: Cracks detected at critical welds on the base, tower mast, slewing ring, or boom sections.

Loss of Spatial Control and Command Signals

The lifting process is a team coordination activity. Communication breakdowns are the leading cause of blind spot collisions:

• Signal interference: Walkie-talkies run out of battery, lose signal, or the construction area is too noisy for the operator to hear commands clearly.
• Signalman leaves their post: The operator is strictly forbidden from spontaneously lifting loads when the signalman moves out of sight or gives non-standard hand signals.
• Violations of safety corridors: Detecting a worker suddenly entering the barricaded area below a suspended load, or the safe distance from the boom arm to high-voltage power lines being breached due to the equipment's hidden swaying motions.

Important Note: All emergency machine stops must be recorded in an on-site incident report and operations are only allowed to resume with written confirmation from the technical department that the issue has been completely resolved.

Regulations on Safety Inspections and Periodic Maintenance

Technical safety inspections for lifting equipment are not merely formal administrative procedures, but extensive mechanical evaluation processes to confirm actual technical conditions against safety thresholds. According to Circular 54/2016/TT-BLDTBXH, this entire process is extremely strictly standardized through specific procedural codes for each type of equipment.

Safety Inspection Procedure for Lifting Equipment

Licensed independent inspection centers are strictly forbidden from skipping any of the following 3 steps:

Step 1: Establishing a diagnostic protocol. The inspector reviews the entire equipment log file, structural drawings, CO/CQ (Certificate of Origin/Quality of materials) certificates, and previous maintenance history.

Step 2: Visual assessment & Non-Destructive Testing (NDT). The human eye can only spot warping or rust on the surface. For hidden cracks deep within welds, it is mandatory to use ultrasonic testing (UT) or magnetic particle inspection (MPI) combined with ultraviolet light to reveal microscopic defects.

Step 3: Actual load testing (Limit testing).

• Static load test: Suspend a standard weight equal to 125% of the theoretical safe working load, holding it slightly above the ground for a minimum of 10 minutes. The purpose is to measure the elastic deflection of the girder, check the leakage pressure of hydraulic seals, and assess whether the braking system allows load drift.
• Dynamic load test: Operate the equipment at 110% of the load, forcing the machine to continuously perform 3 spatial movements: vertical lifting/lowering, horizontal slewing, and longitudinal travel along the rails. This step aims to maximize power output to check dynamic stability and measure the sensitivity of overload limiters (overload limits).

Only when the equipment successfully passes all tests can the inspector issue a report, issue a certificate, and apply an inspection stamp. If any parameter fails, the equipment will be prohibited from receiving a stamp, and the enterprise is forced to thoroughly repair the defects.

Inspection Timeframes

The legal system divides the equipment's operational lifecycle into three core inspection scenarios to maintain a continuous risk filtration system:

• Initial inspection (Design validation): Conducted immediately after completion of on-site installation and before being put into commercial operation, to ensure the transportation or welding/assembly processes have not degraded the original mechanical properties.
• Periodic inspection (Material fatigue assessment): The standard cycle for most cranes and overhead cranes is every 02 years. However, the law places immense emphasis on metal fatigue: for cranes with a service life of over 10 years, the mandatory inspection timeframe is strictly shortened to once a year to prevent sudden fractures caused by accumulated micro-cracks.
• Unscheduled inspection (Rapid response mechanism): Mandatorily triggered after major overhauls (replacing the main girder, re-welding the boom, replacing the load cable), or after remediating an occupational accident. Furthermore, enterprises have the right to proactively request early assessments if a mechanic's technical intuition detects strange noises, vibrations, or abnormal behaviours.

Penalties for Violating Lifting Equipment Safety Regulations

Ignoring lifting equipment safety regulations is not just gambling with the lives of the on-site workforce, but also pushes the enterprise into a spiral of extremely serious legal risks. Therefore, state management agencies apply a very heavy penalty framework with high deterrence for violations in the lifting equipment sector, ranging from economic leverage to criminal liability.

Administrative Penalty Framework (Based on Decree 12/2022/ND-CP)

Current labour law stipulates huge fines to eliminate the "cost-saving over safety" mindset of employers:

• Violations regarding technical inspections: This is a common but most strictly penalized error. A fine ranging from 50,000,000 VND to 75,000,000 VND is imposed on employers who put machinery and equipment with strict occupational safety requirements (like tower cranes, overhead cranes, hoists) into use without a Certificate of Conformity or prior to a technical safety inspection.
• Using unqualified personnel: Handing over equipment to untrained personnel, those without an Occupational Safety Card (Group 3), or without a valid vocational certificate, will be heavily penalized. The fine is calculated progressively based on the number of violating employees, up to a maximum of 50,000,000 VND.
• Evading legal declarations: Failing to declare to the local Department of Labour - Invalids and Social Affairs within 30 days of putting lifting equipment into use (or before dismantling it) will result in an administrative fine ranging from 1,000,000 VND to 5,000,000 VND.

Additional Penalties

From a business management perspective, even more terrifying than paying fines are the additional penalties. The labour inspectorate has full authority to mandate:

• Suspension of the violating lifting machine's operations for 01 to 03 months.
• In cases of systemic violations, the authorities may suspend all construction/production activities in the related area. This interruption creates a disastrous domino effect: disrupting the supply chain, delaying handover schedules, and leading to the risk of massive fines from partners for breaching contracts.

Criminal Liability (Article 295 - Penal Code 2015)

When lifting equipment incidents spiral out of sight control and cause catastrophic consequences (death or causing health damage of 61% or more to others), the case will be criminally prosecuted under Article 295 - "Crime of violating regulations on occupational safety, occupational hygiene, and safety in crowded places".

• Who bears responsibility? Not only the crane operator directly performing incorrect procedures, but also the Health and Safety Executive (HSE), the Site Commander, or the Project Manager (the person ordering the operation while clearly knowing the equipment is unqualified) can become defendants.
• Penalty framework: Offenders can face prison sentences ranging from 01 year up to a maximum of 12 years in prison if the consequences involve the deaths of 03 or more people or cause exceptionally large property damage (over 1.5 billion VND).

Conclusion

Risk management in heavy lifting operations has never been a problem that can be compromised by cutting costs. Absolute compliance with lifting equipment safety regulations and serious execution of inspection procedures is not just a solid legal "shield" for businesses, but also the ultimate respect for the lives of workers. However, any operational procedure, no matter how strict, becomes meaningless if the mechanical structure of the equipment itself inherently harbours flaws from the manufacturing stage.

Instead of facing the risk of construction suspension, contract breach penalties, or mechanical disasters from floating, patched-up lifting machines, the most sustainable risk management solution is to "eliminate the danger in the bud." The starting point of safety must begin with the choice to invest in high-quality lifting equipment systems with genuine origins and transparent technical capabilities.
