Zoomlion rotary drilling rigs span the globe,

and have been successfully applied around the world.

Below we present the rotary drilling rig ZR300D,

and its successful cases in building foundation piles and road/bridge piles.‍

In the heart of Central America, in the Republic of El Salvador, an engineering miracle is gradually taking shape. Our Zoomlion foundation construction machinery, undaunted by hardships, crossed thousands of miles and successfully delivered a ZR300D rotary drilling rig. At present, this Zoomlion rotary drilling rig has become the largest model introduced into the country.

The equipment was towed from Zoomlion's foundation construction base in the Americas, passing through Guatemala and other countries. To meet local road transport capacity limits, Zoomlion service engineer Li Yufeng carried out the disassembly of the counterweight, power head, and tracks under poor site conditions. Amid the towering mountains and ridges of the project site, and under the threat of disasters such as rainstorms and mudslides in the tropical rainforest climate, he organized overnight installation to ensure the safe delivery of the equipment. Under extremely difficult conditions of transport, climate, and geology, Zoomlion's service capabilities efficiently supported the construction of a national key highway in the Republic of El Salvador.

Jumeirah Beach is located in the bustling city of Dubai, with a uniquely advantageous location overlooking the tranquil waters of the Persian Gulf. This idyllic resort is the preferred destination for those planning a beach vacation, where sunshine, sea, and sand blend perfectly. The aurora-green rotary drilling rig ZR300D produced by Zoomlion has also added luster to local construction work. With a pile diameter of 600 mm, a depth of 20 meters, and a casing length of 13 meters. This typical construction application model has already accumulated rich practical experience in the Middle East and has won widespread recognition from local customers.

As an engineering tool specialized for building and bridge pile foundation work, the Zoomlion ZR300D rotary drilling rig has won high recognition from customers worldwide thanks to its powerful performance, outstanding efficiency, and reliability.

This rotary drilling rig has a power head torque of up to 300 kN-m and is equipped with a multi-gear control mode, enabling it to flexibly handle various complex working conditions, such as soil layers and strongly weathered rock layers. It balances excellent performance under both working conditions: high efficiency and fast speed in soil layer construction, and strong rock-entry capability in rock layer construction. The ZR300D rotary drilling rig also features many intelligent applications that greatly reduce the operator's labor intensity. It offers convenient one-key soil dumping, one-key hole sweeping, and automatic positioning of the anchor mast, thereby improving construction efficiency and speed.

In addition, the ZR300D rotary drilling rig adopts a dedicated chassis manufactured by Zoomlion, with the power system and hydraulic system perfectly matched, which not only improves the operating efficiency of the hydraulic system but also achieves more energy-saving and fuel-efficient performance. This efficient and energy-saving design makes it a capable assistant in the infrastructure field.

In the vast global village, Zoomlion foundation construction, with extraordinary strength and unremitting efforts, crosses mountains and seas with craftsmanship to serve every customer.
