Shandong Huaang: Leading The Development Of The Laser Screed Industry With Technological Innovation, Customized Large Telescopic Boom Machines Gain International Customer Recognition

Recently, Shandong Huaang Engineering Equipment Co., Ltd. (hereinafter referred to as "Shandong Huaang") once again won international market favor with its outstanding R&D and manufacturing capabilities. A large telescopic boom laser screed machine specially customized for a customer in Azerbaijan has been successfully produced and is about to be delivered. This equipment, integrating multiple patented technologies and high-end configurations, not only demonstrates Shandong Huaang's profound accumulation in the field of concrete laser screeding, but also marks a more solid step forward for China's high-end engineering equipment manufacturing in the international market.

Shandong Huaang Engineering Equipment Co., Ltd. is located in the National High-tech Industrial Development Zone of Jining, Shandong, the hometown of Confucius and Mencius and the capital of the Grand Canal. Since its establishment, the company has always focused on the R&D, production, sales, and service of concrete laser screed machines, building an integrated industrial system. The company has a professional R&D team and a technical craftsman team of over 100 people. It is this team of meticulous craftsmen that has enabled its laser screed machine products to maintain the top sales position in China for three consecutive years and successfully export to Southeast Asia, the Middle East, Europe, Russia, and other regions around the world. To date, the company has accumulated over 20 national patents and has successively passed authoritative certifications such as ISO9001 international quality system certification and EU CE safety certification, establishing its product quality and safety as a globally recognized standard.

A wealth of honors testifies to its strength. The company has been awarded a series of honors, including "China 315 Integrity Enterprise," "China Industrial Pioneer Demonstration Unit," "National AAA-level Contract-Abiding and Creditworthy Enterprise," "Shandong Provincial High-tech Enterprise," "Shandong Provincial Youth Enterprise," "Top Ten Integrity Enterprises," and "Jining City Excellent Enterprise." These shining plaques and certificates are not only a commendation of Shandong Huaang's honest operation and steady development, but also a powerful demonstration of its comprehensive innovation capabilities and brand influence as an industry leader.

The large telescopic laser screed machine built for a customer in Azerbaijan is a concentrated embodiment of Shandong Huaang's technological innovation. This equipment is not a simple output of standard products, but a deeply customized result based on the customer's actual working conditions and high-efficiency construction needs, fully demonstrating the unique advantages of "Huaang Intelligent Manufacturing."

The equipment is equipped with a powerful Japanese Yanmar 98T four-cylinder water-cooled turbocharged engine, delivering 75 horsepower with low energy consumption and low noise characteristics, ensuring sustained and efficient operation. The unique American Eaton dual-pump system (load-sensitive pump) enables independent and precise control of the walking and working systems, allowing the equipment to maintain unprecedented smoothness and maneuverability even during complex construction operations, including simultaneous walking, boom extension, or rotation.

Additionally, many foreign trade websites integrate social media marketing tools to drive traffic and expand brand awareness through social platforms. To cater to global audiences, these websites should also support mobile access, ensuring customers can browse and purchase seamlessly, no matter where they are.Foreign trade websites have become an effective tool for businesses to expand into international markets, playing a vital role in the global economy.

Leveling System, Precise and Efficient: The leveling system is 4.2 meters wide, with the core leveling head vibrating plate reaching 3.8 meters in length. Made of lightweight, high-strength aluminum-magnesium alloy, it also possesses rust and corrosion resistance. It employs integrated balanced beam hydraulic vibration technology to ensure greater and more uniform vibration force, fundamentally improving the density and surface quality of the concrete. The accompanying 4.1-meter-long hydraulic auger features a thick shaft and small blade design, ensuring dense and uniform paving of the material. Sealed bearings effectively prevent concrete slurry intrusion, significantly extending the lifespan of core components. The innovative design of the auger tilting cylinder and the leveling head turning cylinder makes cleaning and maintenance exceptionally simple, and the construction and turning are flexible. After turning, the overall transport width of the machine is only 2.3 meters, solving the problem of large equipment relocation.

Intelligent and Flexible Movement and Control: The equipment features four-wheel drive and solid, anti-slip, puncture-resistant tires.

Its steering system is exceptional, supporting independent front and rear wheel steering, four-wheel unidirectional "crab walking," and four-wheel counter-directional steering, achieving a minimal turning radius and adapting to various narrow and complex terrains. A high-torque planetary reducer provides ample walking power. The four-leg hydraulic automatic leveling function lays a solid foundation for precise construction. Walking speeds are adjustable, with a maximum speed of 5 km/h to adapt to different work conditions.

Intelligent and User-Friendly Design: The equipment utilizes an internationally leading combination of Trimble 422 transmitters and

410 receivers, achieving millimeter-level precision control (construction error ±1mm). Even after finishing, the maximum error remains within 3mm, a level of accuracy unmatched by its competitors. The unique 6-meter telescopic boom, equipped with sensor cylinders, enables automatic tire return. Dual electric control handles (one for walking and one for boom extension) offer greater precision and convenience compared to traditional mid-sized equipment's steering wheel operation. Huaang's exclusive "one-button lock" safety function automatically restricts the control panel when the equipment is unbalanced, ensuring safety.

Meticulous attention to detail enhances the user experience: The overall design prioritizes operator comfort and ease of maintenance. The control panel features a multi-directional adjustable display for real-time monitoring of construction data; the air-elastic seat adjusts automatically according to weight; and an integrated electrical control cabinet beneath the seat facilitates maintenance. It includes a 100L water tank and a hydraulic washer for rapid daily self-cleaning. A large 110L fuel tank and a low fuel consumption of approximately 6L/H ensure extended operating range. The intelligent temperature-controlled hydraulic oil cooling system (automatic start/stop at 50°C) further embodies the energy-saving and environmentally friendly design philosophy.

This large telescopic boom crane, weighing 8.6 tons and measuring 8000*2400*2300mm, is a true "mobile precision construction platform." Its successful production and delivery not only represents a satisfactory international order for Shandong Huaang, but also vividly illustrates the transformation and upgrading of "Made in China" to "Intelligent Manufacturing in China" in the professional engineering machinery field.

Looking to the future, Shandong Huaang Engineering Equipment Co., Ltd. will continue to uphold the principles of "integrity, innovation, excellence, and win-win cooperation," deeply cultivate laser leveling technology, and contribute Chinese strength to global infrastructure construction with more intelligent, efficient, and reliable equipment and services, solidifying its position as an industry leader.
