As spring brings vitality to Yanzhao and greenery to “Lion City,” Zoomlion recently delivered 50 “Lingguan” new energy mixer trucks in bulk to Cangzhou Jinyan Building Materials Group in Hebei Province. This delivery marks a new stage in the two parties’ cooperation in green and low-carbon transportation. The handover is expected to accelerate the green transformation of Cangzhou’s commercial concrete logistics, injecting new momentum into the achievement of carbon neutrality goals in the Beijing-Tianjin-Hebei region.

   

Yao Shu, Deputy General Manager of Zoomlion’s Domestic Concrete Machinery Marketing Company, stated:

Quote:“This collaboration with Jinyan Group highlights the outstanding market competitiveness of our 'Lingguan' new energy mixer trucks. Moving forward, we will continue to empower our customers with innovative technology and help more enterprises achieve green upgrades.”

Quote:“In the context of China’s dual carbon strategy, Jinyan Group has always been proactive in advancing green transformation. Introducing Zoomlion’s 'Lingguan' new energy mixer trucks is a key step in fulfilling our environmental responsibilities and optimizing our transportation structure. This fleet will significantly reduce carbon emissions, support Cangzhou’s battle for blue skies, and enhance our concrete supply efficiency—contributing more green power to urban development in the Beijing-Tianjin-Hebei region.”

With the strong winds of April "raging in," the crane's "swaying show" might take place unintentionally! During this season of tumultuous weather, we must not only stay professionally vigilant but also approach challenges with a relaxed mindset. Here are some wind safety tips to ensure the safety of the equipment while keeping operations enjoyable, allowing you to stay steady even in strong winds!

   

Wind Speed Red Line: Strictly Follow 9.8m/s

Once the wind speed exceeds 9.8m/s (level 5 wind), never "force" operations. Make it a habit to check weather forecasts in advance every day. Once the wind hits, switch to the "strong wind rest mode" immediately, allowing the crane to rest and "lie down."

Heavy Loads and Height: Big Loads Catch More Wind

The larger the lifted object and the higher the lifting height, the larger the wind-facing area and the higher the center of gravity, which significantly reduces stability. It's recommended to first conduct a small-scale test lift to observe the "swaying show" of the equipment in the wind. Once you're sure it's safe, proceed with the formal operation. Also, don't forget to add counterweights, dressing the crane in a sturdy "windproof armor."

   

Large Wind-Facing Objects: Dangerous Solo Dance in the Wind

Lifting wide steel plates or other large wind-facing objects is like letting a "big fan" dance alone in the air. When the wind hits, it may crash into the boom or cause violent swaying. Tie a "centering rope" to these objects to prevent them from "dancing" freely in the wind, ensuring the equipment remains as steady as a rock.

Empty Load Operation: Keep It Low-Key

If the crane maintains a large boom angle with no load, it’s easy for the wind-facing area to become too large, leading to tipping or accidents. Adjust the boom angle to minimize the wind-facing area, ensuring the crane stands as steady as Mount Tai.
When Wind Speed Exceeds 9.8m/s, Immediately Stop Operations and Follow These Steps:

1. Steadily lower the lifted object to the ground and release the hook to eliminate potential hazards.
   
2. Secure the hook to a counterweight block weighing around 20 tons to prevent the hook from swaying in the wind.
   
3. Adjust the boom angle: For main boom conditions, the boom angle should be changed to 60°~70°; for tower-type conditions, the main boom angle should be 75°, and the tower arm angle should be about 35°.
   
4. Rotate the turntable so that the back of the boom faces the wind, positioning the crane to "stand with its back to the wind," reducing the impact of the wind.
   
5. Close all brakes and ratchet devices, and lock the turntable with the turntable locking pin.
