Frequently Asked Questions (FAQ)

Q: What is the maximum rated lifting capacity of this crane?

The crane has a maximum rated lifting capacity of 55 tonnes at a working radius of 3.5 meters.

Q: What are the boom and fixed jib length options?

The main boom length ranges from 13 to 52 meters, while the fixed jib length ranges from 9.15 to 15.25 meters. The maximum combined configuration is 43 meters of boom plus 15.25 meters of fixed jib.

Q: What type of engine configuration does this machinery use?

It offers dual configuration options: an imported engine rated at 142 KW/rpm and a domestic engine option rated at 132 KW/rpm.

Q: How does the gravity lowering function benefit construction operations?

The unique gravity lowering function enables efficient load descending by using the object's gravity, which significantly reduces fuel consumption and increases overall working efficiency.

Q: What are the transport dimensions of the crane?

The shipping transport dimensions are 7400 mm in length, 3300 mm in width, and 3170 mm in height, allowing for convenient logistics planning.

Q: Is this crane suitable for confined or complex construction environments?

Yes, its compact and optimized structural design, paired with complete safety systems and a rotary floating function, makes it highly suited for precise operations in confined and complex job sites.
