As the core equipment of modern construction, boom pump trucks play an irreplaceable role in high-rise buildings, complex terrains and special projects with their flexible boom system and powerful pumping capacity. This article will systematically explain its scope of application and construction safety specifications in combination with actual application scenarios.
1. Boom pump trucks are suitable for construction scenarios
(I) High-rise buildings and super-high-rise projects
Boom pump trucks can achieve flexible vertical and horizontal extension through multi-section folding booms, covering a height range of 20-101 meters. The 101-meter carbon fiber boom pump truck developed by Zoomlion, with its seven-bridge heavy-duty truck chassis and 620-horsepower V8 engine, successfully transports concrete to the top of buildings above 30 floors. This type of equipment can significantly reduce manual handling costs and improve pouring efficiency in super-high-rise building construction.
(II) Construction in complex terrain and narrow spaces
In mountain bridges, tunnels, basements and other scenes, boom pump trucks show excellent adaptability. Its boom can be folded at multiple angles, and can bypass obstacles and go deep into narrow areas. For example, in mountain bridge construction, the equipment can cross deep valleys and directly transport concrete to the bridge piers; in tunnel construction, the arch pouring can be completed by adjusting the boom posture.
(III) Factory and Industrial Facility Construction
The factory has a wide internal space but a complex structure. The boom pump truck can achieve rapid concrete delivery by precisely controlling the boom extension length and angle. In a small space, the equipment can bypass obstacles such as columns by folding the boom at multiple angles to complete concrete pouring in corners.
(IV) Municipal Engineering and Infrastructure Projects
In municipal roads, water conservancy facilities, and disaster relief, boom pump trucks have become the preferred equipment due to their mobility and efficiency. For example, in road repair projects, the equipment can quickly complete the pouring of road concrete; in flood control dam construction, the boom can be extended to achieve long-distance transportation.

2. Key points for safe operation of boom pump truck construction
(I) Equipment deployment and basic requirements
Site selection: The parking area needs to be hardened to ensure that the ground bearing capacity meets the equipment's deadweight requirements. The parking location should avoid dangerous areas such as high-voltage lines, and the safe distance between the end of the boom and the high-voltage line must comply with the "Technical Specifications for Temporary Electricity Safety at Construction Sites".
Outrigger fixation: All outriggers must be extended and reinforced before operation, and a level meter must be used to check the level of the equipment. The stability of the outriggers must be confirmed before operating the boom, and it is forbidden to start the fabricating boom when it is not fixed.
(II) Boom operation specifications
Wind force limit: When the wind force exceeds level 6, it is prohibited to use the boom for laying operations; in strong winds above level 8, construction must be stopped immediately and the boom must be retracted.
Operation sequence: The boom must be unfolded in the order specified in the instructions, and overstepping operations are prohibited. If abnormal movements occur during operation, the emergency stop button should be pressed immediately and repaired by professionals.
Vision control: The entire boom operation must be carried out within the operator's field of vision, and it is prohibited to direct the operation through the rearview mirror or others. The diameter of the end hose swing area is twice the length of the hose, and a warning area must be set during operation.
(III) Pipeline system safety
Pipeline inspection: Before taking over the pipe, it is necessary to confirm that there are no cracks on the pipe wall and no damage to the joints. The suspended crossing section must be equipped with a steel pipe rack and reinforced with anchor steel bars.
Connection specifications: Special clamps must be used to fix the pipes, and non-standard connectors such as iron wire are prohibited. A horizontal straight pipe with a length of ≥10 meters must be installed at the front end of the vertical pipe, and a check valve must be installed.
Pressure management: It is prohibited to open any delivery pipes and hydraulic pipes when the pumping system is under pressure. Before maintenance, the pressure must be relieved and it must be confirmed that there is no residual pressure in the pipeline.
(IV) Personnel protection and emergency measures
Operation area: No one is allowed to stand within 1 meter on both sides of the conduit and within 30 meters in front of the discharge port. Safety belts must be worn when installing the conduit against the wall, and the conduit must be reliably connected to the wall after installation.
Cleaning specifications: When cleaning the pipeline, no one is allowed to stand within 10 meters in front of the outlet, and a metal mesh basket must be used to collect the flushed objects. It is prohibited to use compressed air to flush the distribution rod piping.
Emergency treatment: When the pipeline is blocked, it must be handled in the order of reverse pumping-dismantling and cleaning-reassembly. It is strictly forbidden to forcibly dismantle the pipeline under high pressure.
3. Typical Cases and Technology Development
During the construction of the Hong Kong-Zhuhai-Macao Bridge, the boom pump truck successfully completed the concrete pouring of the submarine immersed tube tunnel through customized boom design. With the application of carbon fiber materials and intelligent control technology, the weight of the new generation of pump truck booms is reduced by 40%, and the failure rate of the hydraulic system is reduced by 60%. In the future, boom pump trucks will develop in the direction of longer booms, lower energy consumption, and higher intelligence, providing more efficient and safer solutions for construction.
As the "long arm in the air" of construction, the wide range of application scenarios and strict operating specifications of boom pump trucks together constitute the core technical support of modern engineering construction. Construction units need to combine equipment characteristics with engineering requirements to formulate scientific safety management plans to ensure both construction efficiency and personnel safety.
