BRIEF

Machine Model Introduction
The folding arm crane models currently produced by Sany Palfinger are all original imports of models that have been sold in Europe for more than 10 years, and they adhere to consistent design and quality control standards.
Ultra-low Self-weight
Some key components use imported Saab steel plates. While ensuring the lifting capacity of the crane, this reduces the self-weight, increases the customer’s cargo carrying capacity, and improves fuel economy.
Customized Design Based on Demand
Customers can select telescopic jibs, remote controls, winches, auxiliary tools, etc. according to their needs. With mature design solutions, one machine can serve multiple purposes.
Standard Filter
All models in the series are equipped with high-pressure filters as standard, which improves the cleanliness of the oil, reduces crane failures, and extends the service life. There are also super-large span rotating outriggers.
High-speed Movement
The high-speed movement system of the telescopic arm enables the return oil to re-enter the pressure circuit instead of flowing back to the control valve. The increased hydraulic pressure makes the cylinder move faster.

FEATURES

De Sany 70.1 Ton Knuckle Boom Crane is a pinnacle of engineering excellence, designed to meet the most demanding heavy-lifting requirements across diverse industries.

Outstanding Lifting Capacity

With an impressive 70.1-ton lifting capacity, this crane stands as a true powerhouse. It is capable of handling colossal loads, such as massive industrial machinery, large-scale bridge components, and hefty structural steel pieces used in high-rise construction. The advanced hydraulic system integrated into the crane ensures smooth and stable lifting operations, even when dealing with maximum-capacity loads. This reliability makes it an indispensable asset for large-scale infrastructure projects and heavy industrial applications.

Flexible Knuckle Boom Design

The knuckle boom design is a standout feature of the Sany crane. It consists of multiple articulated sections that can be maneuvered with great flexibility. This allows operators to reach difficult and confined spaces that traditional cranes might struggle to access. The ability to bend and extend the boom in various directions enables precise positioning of the load. For example, in shipyard operations, the knuckle boom can navigate around the complex structures of vessels to load and unload heavy cargo. In urban construction projects, it can work in tight spaces between buildings, making it highly adaptable to different job-site scenarios.

Precise Control and Operation

Equipped with state-of-the-art control systems, the Sany 70.1-ton knuckle boom crane offers operators precise control over every movement. The intuitive controls allow for smooth and accurate boom extension, retraction, and rotation. This precision is crucial when handling delicate or valuable loads that require careful placement. I tillegg, the crane’s advanced sensors and monitoring systems provide real-time feedback on the load status, boom position, and operating conditions, ensuring safe and efficient operation at all times.

Enhanced Mobility and Maneuverability

Mounted on a robust and well-designed carrier, the crane offers good mobility. It can be transported to different job sites relatively easily, reducing the time and cost associated with equipment relocation. Despite its large size and heavy-duty capabilities, the crane’s design allows for decent maneuverability. It can navigate through large construction sites and industrial areas, making it suitable for projects where the crane needs to move around frequently.

Comprehensive Safety Features

Safety is at the core of the Sany 70.1-ton knuckle boom crane‘s design. It is equipped with a comprehensive set of safety features, including load moment indicators that constantly monitor the load and the crane’s operating conditions to prevent overloading. Anti-two-block systems are installed to avoid collisions between the hook and the boom. The outriggers are designed to provide maximum stability during lifting operations and can be adjusted according to the ground conditions. The operator’s cab is ergonomically designed with excellent visibility and safety features to reduce operator fatigue and ensure safe operation.

Durability and Low Maintenance

Constructed with high-quality materials and advanced manufacturing techniques, the Sany 70.1-ton knuckle boom crane is built to withstand the harshest working conditions. Its components are engineered for durability, reducing the frequency of breakdowns and maintenance requirements. The robust construction ensures a long service life, minimizing downtime and overall operating costs, making it a cost-effective investment for businesses.
