JUZ hydraulic long auger drilling rig

The JUZ series high torque fully hydraulic long spiral drilling rig is a heavy-duty construction equipment developed by our company and Beijing Construction Mechanization Research Institute to meet the needs of domestic long spiral drilling rig rock construction. It integrates mechanical, electrical, and hydraulic components. This product inherits the pile driving technology developed by Zhenzhong Company for many years, integrates new hydraulic and electrical control systems, and is a new type of high torque fully hydraulic long spiral drilling rig developed through upgrading the performance and quality of the product. It combines the advantages of various types of drilling rigs at home and abroad, with fully hydraulic drive, convenience, speed, and good stability. This equipment can also be used to suspend dual power down the hole hammer rock drilling rig, as well as to suspend resonance free mid hole vibration pile hammer for vibration casing long spiral drilling rig construction method. The JUZ series high torque fully hydraulic long spiral drilling rig is a high-performance and high stability construction equipment for underground pile foundation construction such as building bridges, ports, and underground continuous walls.

Product Performance

JUZ series high-torque full-hydraulic long auger drilling rig is a heavy-duty construction equipment newly developed by our company and Beijing Institute of Construction Mechanization to meet the needs of domestic long auger drilling rigs for rock-entry construction. This product inherits the pile driver technology developed by Zhenzhong Company for many years, incorporates new hydraulic and electrical control systems, and develops a new type of high-torque full-hydraulic long auger drill through upgrading the performance and quality of the product. The advantages of various types of drilling rigs, full hydraulic drive, convenient and fast, good stability. The equipment can also hang a double-power down-the-hole hammer rock drilling rig, and can also hang a resonance-free middle-hole vibrating pile hammer for the construction of the vibrating casing long auger drilling rig. JUZ series high-torque full-hydraulic long auger drilling rig is multi-performance and high-stability construction equipment for underground pile foundation construction such as building bridges, ports, and underground diaphragm walls.

●The performance of the whole machine is well matched

The performance of the whole machine is reasonably matched, one machine is multi-purpose, and the construction is suitable for a wide range of applications.

●Fully hydraulic heavy-duty crawler chassis

The hydraulic crawler chassis is adopted, and the displacement is quick and convenient. The stability of the whole machine meets the requirements of national standards.

●Adjustable speed hydraulic motor drive

The walking, hoisting, and slewing mechanisms are all driven by hydraulic motors, which are convenient for speed regulation and Compact structure, stable operation, strong impact resistance.

●Column with fine-tuning function

The column has the function of fine-tuning front and rear, which is convenient and fast for pile alignment; it is equipped with a vertical instrument, which can quickly adjust the verticality.

●Combined counterweight

The counterweight is retractable, increasing the stability during work.

●Pulling force limiter

Design a variety of drilling tools according to different geological conditions.

●Speed torque can be automatically adjusted

The power head is driven by two variable variable hydraulic motors, the speed and torque of the power head can be automatically adjusted according to the force of the drilling tool to adapt to different geological conditions, and the work efficiency is high.

●Diversification of drilling tools

The eccentric moment can be adjusted conveniently and freely during the operation of the machine to adapt to the pile sinking and pulling requirements of different soil layers, so as to achieve the ideal pile sinking and pulling speed and efficiency.
