It is smart, high-end, and powerful. Sany crawler cranes can be said to satisfy everyone's imagination of machinery. How to make the huge and complex machinery safe and convenient to operate is a problem that Sany has been thinking about. Today, let's have a try, you don't know these "black technologies" of Sany crawler cranes.

Intelligent disassembly, easy to lift

Crawler crane, as a member of the heavy lifting equipment family, its disassembly and assembly is a complex and challenging work. Sany breaks through the technical bottleneck, making the tedious disassembly and assembly work easier.

One-key extension/retraction of outriggers: Through digital analysis of the slope of different road surfaces, the outrigger balance is automatically adjusted. In just 2 minutes, the 4 outriggers can be extended/retracted into place.

One-button mast hoisting/lowering: improve the drawbacks of traditional hoisting cylinder telescopic and luffing hoisting and unwinding requiring multiple operations. With just one key, it can be automatically and quickly hoisted or lowered within the range of 70-180° .

One-key auxiliary rope threading: Overcome the technical problem of manual rope threading. Through the coordinated action of the main winch and the traction winch, the wire rope threading and winding operation can be completed simply and efficiently, saving time, effort and labor.

Intelligent lifting arm control for tower conditions: Real-time monitoring of tension, angle, and safety protection sensors, and through adaptive algorithms, the main boom and jib can act in concert to quickly and accurately realize the operation of the tower condition lifting or lowering boom.

Intelligent assistance, in one step

In order to meet the needs of different working conditions, Sany has developed a number of "black technologies" based on different construction scenarios to maximize work efficiency.

Hook height-fixing technology: The hoisting hoist automatically compensates for the height difference generated during the luffing process to ensure that the relative height of the heavy object and the ground remains unchanged, and eliminates the potential safety hazard that the heavy object may touch the ground and hit the top during the luffing process.

One-key shield turning/leveling technology: By operating a handle, you can precisely control the shield machine to "turn over and go down". At the same time, the torque distribution of the main hook and the auxiliary hook is completed to prevent overloading of the crane.

Lifting, luffing and turning angle one-key in-position function: the hook can be lifted to the specified height, the boom can be automatically luffed to the in-position range, and the hook can be automatically rotated to the target position.

Security guarantee, intelligent escort

In the actual construction process, operators often have to face complex construction environments. For this reason, Sany has made every effort to create a safety performance system.

Center of gravity control and grounding specific pressure warning technology: avoid crane overturning accidents caused by misoperation or ground collapse. Real-time display of the position of the center of gravity of the current working condition of the crane, as well as the required maximum grounding specific pressure,

Recognition function of hoisting disordered ropes: Abandoning the previous mode of directly checking the disordered ropes of the hoisting machine, collecting the winding status of the hoisting and hoisting wire ropes through AI equipment, and conducting real-time comparative analysis to identify the abnormal status of disordered ropes and give early warning.

Digital wind speed early warning system: monitor wind speed and wind direction changes within 60 kilometers 30 minutes in advance, and guide operators to operate safely, avoid risks and ensure construction safety.Editor/Ma Xue
