How to choose the right aerial work platform for use?

As a core special equipment in fields such as construction, municipal maintenance, power repair, and venue operation and maintenance, the rationality of the selection of aerial work platforms directly determines the safety, efficiency and full life cycle cost of operations. According to data from Zhiyan Consulting, the market size of aerial work platforms in China reached 7.453 billion yuan in 2024 and is expected to increase to 8.562 billion yuan in 2025. The number of equipment in use has exceeded 280,000 units, and the industry's demand for professional and compliant selection continues to rise. Based on authoritative standards such as GB/T 9465-2018 "Aerial Work Platforms" and GB/T 25849-2024 "Design, Calculation, Safety Requirements and Test Methods for Mobile Lifting Work Platforms", and in combination with industry practice and data, this article systematically expounds the full-process norms for the selection and commissioning of aerial work platforms.
I. Core Prerequisite for Selection: Precise matching of working conditions

Working condition adaptation is the primary principle in selection. It is necessary to take into account four core dimensions: working height, working environment, load-bearing requirements, and working radius, to avoid "overqualified personnel for underutilization" or "insufficient capacity".

(1) Select the type based on the height and type of the operation

According to the GB/T 9465-2018 standard, the maximum working height of aerial work platforms covers 6 to 100 meters, and different heights correspond to different models.

1. Low-altitude operations ranging from 6 to 14 meters: Scissor lift aerial work platforms are preferred. They are suitable for factory maintenance, interior decoration, and low-rise municipal inspections. They have the advantages of small floor space, stable load capacity, and low cost. By 2025, the penetration rate of low-altitude operations in the construction field has reached 35%.
2. 14-28m hollow operations: Articulated boom aerial work platforms are recommended. They are suitable for narrow Spaces and complex obstacle scenarios, such as the renovation of old residential areas and internal maintenance of venues. In 2023, the renovation projects of old residential areas have driven the proportion of articulated boom vehicle purchases to increase to 42%.
3. High-altitude operations above 28 meters: Straight boom aerial work platforms are selected to meet the long-distance high-altitude requirements such as ultra-high voltage maintenance of power plants, construction of high-rise building facades, and bridge maintenance. The maximum horizontal extension distance can reach over 30 meters.

(2) Select the model based on the working environment and special requirements

1. Indoor/confined space: Choose electric aerial work platforms, which are zero-emission and low-noise, meeting environmental protection and indoor operation requirements. By 2025, the market share of electric models in Europe and America will exceed 12%, and the penetration rate in domestic municipal and venue fields will increase year by year.
2. Complex outdoor road conditions: Select off-road chassis and large-tire models. The minimum ground clearance should not be less than the standard of Class II chassis. The approach Angle should be ≥15° and the departure Angle ≥8°. It is suitable for muddy, sloping and other unpaved roads.
3. Live-line work in the power industry: Insulated aerial work platforms must be selected. Complete factory test reports on insulation performance must be provided, meeting the mandatory insulation performance requirements of GB/T 25849-2024. The average annual growth rate of demand for insulated vehicle models in the power industry is 18%.
4. Confined space operations: Prefer models with folding arms and compact chassis, with a turning radius of no more than 3.5m, suitable for restricted Spaces such as urban streets and alleys, and gaps between buildings.

(3) Select the type based on the load capacity and working radius

According to the GB/T 25849-2024 standard, the rated load of the aerial work platform is divided into four grades: 200kg, 300kg, 450kg, and 500kg. When selecting the model, a 20% safety redundancy should be reserved. At the same time, when selecting models based on the horizontal extension distance, the horizontal extension capacity of straight-arm models is superior to that of articulated ones. It is necessary to match the distance requirements between the operation point and the parking point to avoid overturning risks caused by over-range operations.

Ii. Core Bottom Line for Selection: Strictly adhere to safety and compliance standards

Aerial work platforms are classified as special equipment. Compliance is the prerequisite for their use. They must meet three major requirements: national standards, safety devices, and qualification certifications. Any illegal selection is strictly prohibited.

(1) Comply with national mandatory standards

The selected equipment must pass the full item inspection of GB/T 9465-2018 "Aerial Work Platforms". This standard covers the entire chain of norms including term definitions, technical requirements, test methods, and inspection rules. After replacing the 2008 version of the standard, it has strengthened core requirements such as safety devices, stability, and insulation performance. At the same time, it is necessary to meet relevant standards such as GB 7258 (Technical Conditions for the Operation Safety of Motor Vehicles) and GB 3847 (Engine Emissions) to ensure dual compliance during driving and operation.

(2) Verification of essential safety devices

According to the technical requirements of Chapter 5 of GB/T 9465-2018, qualified aerial work platforms must be equipped with the following safety devices, none of which can be missing:

1. Interlocking system: The boom cannot move when the outriggers are not fully extended. When the boom is not retracted, the outriggers cannot be retracted, eliminating the risk of misoperation.
2. Emergency devices: Equipped with an emergency stop button and an emergency pump, the platform can safely fall back in the event of power failure or malfunction.
3. Limit protection: The lifting, luffing and slewing limit switches are sensitive and reliable. For models with a maximum working height of ≥20m, upper and lower communication devices must be equipped.
4. Protective devices: The height of the guardrail on the working platform is no less than 1.1m, the base plate is anti-slip, and the legs are equipped with anti-slip tire overturn measures. The protection grade of the electrical system is no less than IP54.

(3) Review of manufacturer and equipment qualifications

1. The manufacturer must have a special equipment production license and ISO9001 quality system certification. Core components (hydraulic cylinders, electrical control systems, outriggers) must provide original factory qualification certificates.
2. The equipment shall provide the factory certificate of conformity, type test report and third-party inspection report. Imported models shall comply with the international standards of EU EN 280 and US ANSI/SAIA A92.
3. Operators must hold a special equipment operation certificate, complete no less than 40 hours of theoretical and practical training, and meet the training requirements of GB/T 27548-2011.

Iii. Key Dimensions for Selection: Comprehensive assessment of performance and cost

Selection should take into account both short-term procurement costs and long-term usage benefits, and make a comprehensive decision based on equipment performance, maintenance costs, service life, and leasing/procurement models.

(1) Evaluation of core performance parameters

1. Power system: The diesel version is powerful and has a long range, making it suitable for long-distance outdoor operations. The electric model is energy-saving, environmentally friendly and has low maintenance costs, making it suitable for indoor and short-distance high-frequency operations. Hybrid models combine the advantages of both and will become the mainstream trend in the industry by 2025.
2. Chassis performance: Prioritize the use of well-known brand second-class chassis (such as Dongfeng, Foton, and Sinotruk), which offer better load-bearing capacity and driving stability, reducing the risk of later failures.
3. Hydraulic system: The core hydraulic cylinders and multi-way valves should be selected from imported or domestic first-line brands to ensure smooth lifting and no leakage, and comply with the GB/T 3811-2018 Crane Design Code.
4. Control System: Equipped with dual control of wireless remote control and platform, it is easy to operate and has a self-diagnosis function for faults, which improves work efficiency.

(II) Full life cycle cost accounting

According to industry research data, in the total life cycle cost of aerial work platforms, procurement cost accounts for 35%, maintenance cost for 40%, fuel/electricity cost for 20%, and residual value for 5%. When making a selection, key attention should be paid to:

1. Maintenance convenience: Prioritize brands with strong universality of spare parts and wide coverage of after-sales service outlets to reduce waiting time and costs for maintenance.
2. Service life: High-quality models are designed to have a service life of no less than 10 years, with an average annual operating time of over 2,000 hours. Inferior models only last for 5 to 6 years, with a failure rate that increases by three times.
3. Leasing and Procurement Decisions: Short-term operations (≤6 months) are given priority for leasing. The penetration rate of the domestic aerial work platform leasing market is expected to reach 65% by 2025. Choose to purchase for long-term and high-frequency operations (≥1 year) to reduce the overall cost.

Iv. Operational Norms: Full-process control ensures safety

After the selection is completed, it is necessary to strictly follow the GB/T 39747-2021 "Safety Regulations for the Use of Lifting Work Platforms", and do a good job in the full-process management of acceptance, training, operation and maintenance.

(1) Equipment acceptance and commissioning

After the goods arrive, verify the consistency between the model, parameters, qualification documents and the contract, and conduct no-load, rated load and 1.25 times overload tests to test the effectiveness of the safety devices.
2. Debug the actions of the outriggers, booms and platforms, and check that the hydraulic system has no leakage and the electrical system has no faults, meeting the requirements of the GB/T 9465-2018 test method.

(2) Safety inspection before work

Before each operation, a 10-minute inspection must be completed: the outriggers are not deformed, the tires are in good condition, the guardrails are firm, the emergency devices are effective, and the load does not exceed the standard. It is strictly prohibited to operate in violation of regulations on slopes, soft ground, or under overhead lines.

(3) Daily maintenance and scrapping management

1. Regular maintenance: Check the hydraulic oil and filter elements every 50 hours, lubricate the components every 200 hours, conduct a comprehensive overhaul every 1000 hours, and establish a maintenance ledger.
2. Scrapping standards: If the height deviation of the operation exceeds 5%, structural deformation occurs, safety devices fail, or the service life exceeds 15 years, it must be compulsorily scrapped to prevent over-service.

V. Conclusion

The selection and commissioning of aerial work platforms is a systematic project that emphasizes "working condition matching, safety compliance, performance adaptation, and cost control". It should be based on authoritative standards such as GB/T 9465-2018 and GB/T 25849-2024, combined with industry data and practical experience, to prevent blind selection and illegal use. With the development of electrification and intelligence in the industry, the market for aerial work platforms is expected to expand at an average annual growth rate of 6.8% from 2025 to 2030. Only by establishing a standardized selection and usage system can enterprises maximize the value of equipment while ensuring safety and meet the high-quality development needs of the industry.
