Aerial Work Vehicle Information

What is Aerial Work Vehicle

Aerial Work Vehicle is a special vehicle used to transport workers and work equipment to a specified height for operation. It is both a special-purpose vehicle and a construction machine. It consists of an aerial work device installed on a vehicle chassis, including components such as working arms, rotary platforms, sub-frames, work buckets, hydraulic systems, and control devices.

 

History of Aerial Work Vehicle

 

In 1960, aerial work vehicles were used for pruning and fruit harvesting in orchards in California, USA,揭开了高空作业车的发展史. In 1966, the aerial work vehicle developed by Selme Company was first exhibited at the mechanical exhibition sponsored by the California Rental Industry Association (CRA), and then began small-batch production. In the 1970s, countries such as the United States, Japan, the United Kingdom, Finland, Sweden, France, and Germany successively began mass production of various models and specifications of aerial work vehicles.

 

Purpose of Aerial Work Vehicle

 

Aerial work vehicles are mainly used for maintenance and construction work in various industries, such as power, telecommunications, construction, gardening, etc. They can also be used by firefighters for emergency access. They provide temporary access to inaccessible areas at height, allowing workers to perform tasks such as equipment installation, maintenance, and repair.

 

Principle of Aerial Work Vehicle

 

Aerial work vehicles usually use hydraulic or electric systems to control the lifting and movement of the working platform. The hydraulic system drives the working arm to extend, retract, lift, and rotate through hydraulic cylinders and motors, enabling the work bucket to reach the required height and position. The electric system is mainly used for controlling and monitoring the operation of the vehicle, ensuring the safety and stability of the work.

 

Features of Aerial Work Vehicle

 

1. High work efficiency: It can quickly transport workers and equipment to the work area, reducing the time and labor required for manual climbing or using other temporary access methods.
2. Good safety performance: Equipped with safety devices such as safety locks, limit switches, and emergency stop buttons to ensure the safety of workers during operation. The stable structure and reliable hydraulic system also reduce the risk of accidents.
3. Strong adaptability: It can be used in various working environments, such as construction sites, power plants, airports, and urban streets, and can adapt to different working heights and load requirements.
4. Easy to operate: The control system is simple and intuitive, and workers can easily master the operation methods after short-term training, improving work efficiency.
5. Multi-functional: Some aerial work vehicles can be equipped with additional functions and accessories, such as cranes, drilling machines, and welding equipment, to meet different work needs.

 

Types of Aerial Work Vehicle

 

 

• Vertical Lifting (Scissor-type) Aerial Work Vehicle: The scissor mechanical structure ensures high stability of the lifting platform, with a spacious work platform and high load-bearing capacity. It is suitable for operations that require a large working area and can accommodate multiple workers or equipment simultaneously.


• Articulated Boom Lift Aerial Work Vehicle: It has a compact articulated structure, is convenient to move, and can directly connect to AC power or use the vehicle's own power to start. The telescopic boom allows the work platform to both lift and extend, with 360-degree rotation, making it easy to bypass obstacles and reach the work position.


• Telescopic Boom Aerial Work Vehicle: Mainly divided into straight boom aerial work platforms and articulated boom aerial work platforms. They are mostly used in places with high height requirements, offering good safety and mobility but at relatively high cost.


• Self-Propelled Aerial Work Platform: It can be controlled to lift and walk without the need for personnel to descend from the platform, allowing equipment control and movement on the platform to other work locations. The equipment itself has walking and steering driving functions, requiring no manual towing or external power supply.


• Mixed Arm Aerial Work Vehicle: Combines the advantages of telescopic and folding arms, providing better work performance and flexibility. It is suitable for complex working environments and tasks that require a large working range.

 

 

Precautions for using Aerial Work Vehicle

 

 

• Before operation, it is necessary to conduct a comprehensive inspection of the vehicle to ensure that all components and systems are in normal working condition, including checking the hydraulic system, electrical system, working arms, and safety devices.


• The operator must hold a valid operation license and receive professional training to familiarize themselves with the operation methods and safety regulations of the aerial work vehicle.


• When selecting a parking position, choose a solid and level ground to ensure the stability of the vehicle. Avoid parking on slopes or soft ground. If necessary, use outriggers or other support devices to increase stability.


• During operation, strictly follow the operating procedures and instructions, and avoid rapid or violent operations to prevent accidents caused by inertia or instability.


• Pay attention to the surrounding environment and weather conditions during operation. In case of strong winds, heavy rain, or other adverse weather conditions, stop operation immediately to ensure the safety of personnel and equipment.


• Regularly maintain and service the aerial work vehicle to ensure its performance and service life. Replace hydraulic oil, filters, and other wearing parts in a timely manner according to the maintenance manual.

 

 

Things to consider when purchasing Aerial Work Vehicle

 

 

• Working height and reach: Determine the required working height and reach according to the actual work needs to ensure that the selected aerial work vehicle can meet the work requirements.


• Load capacity: Consider the weight of the workers, equipment, and materials to be carried to select an aerial work vehicle with an appropriate load capacity.


• Power source: Choose between hydraulic or electric power according to the working environment and requirements. Hydraulic-powered vehicles usually have greater power and load capacity, while electric-powered vehicles are more environmentally friendly and suitable for indoor or noise-sensitive areas.


• Type and structure: Select the appropriate type and structure of the aerial work vehicle according to the specific work environment and tasks, such as vertical lifting, articulated boom, or telescopic boom types.


• Brand and quality: Choose well-known brands and reliable manufacturers to ensure the quality and after-sales service of the aerial work vehicle. Read product reviews and user feedback to understand the performance and reliability of different models.


• Price and cost: Set a reasonable budget based on your actual situation and compare the prices and costs of different models and brands. Consider not only the purchase price but also the maintenance cost, fuel consumption, and other long-term costs.
