BRIEF

Model Introduction
All the folding arm crane models currently produced by Sany Palfinger are original imports of models that have been sold in Europe for more than 10 years, and they adopt the same design and quality control standards.
Ultra-low Self-weight
Imported Saab steel plates are used for some key and important parts. While ensuring the lifting capacity of the crane, this reduces its self-weight, increases the cargo carrying capacity for customers, and improves fuel economy.
Design on Demand
Telescopic jibs, remote controls, winches, auxiliary tools, etc. can be optionally configured according to customers’ needs. There are mature design solutions, enabling one machine to serve multiple purposes.
Standard Filter
High-pressure filters are standard equipment for all models in the series. They can improve the cleanliness of the oil, reduce crane failures, and extend the service life. The cranes are also equipped with super-large span rotating outriggers.
High-speed Movement
With the high-speed movement system of the telescopic arm, the return oil re-enters the pressure circuit instead of flowing back to the control valve. The increased hydraulic pressure makes the cylinders move faster.

FEATURES

The Sany 57.3 Ton Knuckle Boom Crane is a behemoth in the world of heavy – lifting equipment, engineered to handle the most demanding tasks with precision and efficiency.

Exceptional Lifting Capacity

Boasting an astonishing 57.3 – ton lifting capacity, this crane is a force to be reckoned with. It can effortlessly hoist extremely heavy loads, such as large – scale steel structures for skyscrapers, massive bridge components, and oversized industrial machinery. In large – scale construction projects like the building of high – rise commercial buildings or long – span bridges, the crane’s immense lifting power ensures that construction materials can be moved to their exact positions, significantly accelerating the construction process. The advanced hydraulic system provides a smooth and stable lifting motion, even when dealing with maximum loads, guaranteeing the safety of both the load and the surrounding workers.

Flexible and Adaptable Knuckle Boom Design

The knuckle boom design of this crane sets it apart from traditional cranes. Comprising multiple articulated sections, it offers unrivaled flexibility. This allows operators to navigate around complex obstacles and reach areas that are otherwise inaccessible. For example, in urban construction sites surrounded by existing buildings and infrastructure, the crane can precisely position its boom to place heavy materials in tight spaces. The ability to adjust the boom’s angle and position with pinpoint accuracy enables highly precise load placement, reducing the risk of errors and enhancing overall construction efficiency.

Advanced and Precise Control System

Equipped with state – of – the – art control mechanisms, the Sany 57.3 – ton knuckle boom crane offers operators unrivaled control over its movements. The control panel is designed to be intuitive, allowing for seamless extension, retraction, and rotation of the boom. Advanced sensors and monitoring systems provide real – time feedback on the load status, boom position, and all crucial operating conditions. This wealth of information empowers operators to make informed decisions instantaneously, ensuring that the crane operates at peak efficiency while maintaining the highest safety standards.

Robust Mobility and Maneuverability

Despite its colossal size and weight, the crane is mounted on a well – engineered carrier that provides good mobility. It can be transported to different job sites with relative ease, minimizing the time and cost associated with equipment relocation. On – site, its maneuverability is surprisingly good, considering its capacity. The crane can navigate through large construction sites, making it suitable for a wide range of projects, from large – scale industrial plant construction to major infrastructure development.

Comprehensive Safety Features

Safety is at the forefront of the Sany 57.3 – ton knuckle boom crane’s design. It is equipped with a suite of safety features, including a highly sensitive load moment indicator that continuously monitors the load and prevents overloading. An advanced anti – two – block system safeguards against dangerous hook – boom collisions. Adjustable outriggers provide maximum stability during lifting operations, ensuring the safety of the equipment, the load, and the operators. The operator’s cab is ergonomically designed with excellent visibility and safety features, reducing operator fatigue and enhancing overall safety.

Durability and Low Maintenance

Constructed using high – quality, heavy – duty materials and advanced manufacturing techniques, the Sany 57.3 – ton knuckle boom crane is built to withstand the harshest working conditions. Its components are engineered for long – lasting performance, minimizing the frequency of breakdowns and maintenance requirements. This not only reduces downtime but also cuts down on long – term operating costs, making it a cost – effective investment for businesses involved in large – scale construction and heavy – lifting operations.
