Frequently Asked Questions About Travelling Mechanism for Tower Crane

Q1: What is a travelling mechanism for a tower crane?

A1: A travelling mechanism (or travelling chassis) is the mobile base system that allows a traveling-type tower crane to move smoothly along dedicated steel rails on a construction site. By removing the travelling chassis, the tower crane can be converted into a fixed stationary type.

Q2: Why is the travelling mechanism important for tower crane operation?

A2: The travelling mechanism significantly expands the operational radius and working range of the tower crane. Instead of remaining fixed in one location, a rail-mounted tower crane can transport heavy materials across long linear construction sites, improving material handling efficiency and reducing the total number of cranes required on site.

Q3: What major brands and models are compatible with these travelling chassis?

A3: High-quality travelling chassis are designed for broad compatibility with major global tower crane brands, including SYM, SCM, YONGMAO, and ZOOMLION. They can be custom-fitted or selected according to standard mounting interfaces.

Q4: What are the standard models and sizes available?

A4: The common general specifications for tower crane travelling mechanisms include:

• 10m x 10m

• 8m x 8m

• 6m x 6m

• 4.5m x 4.5m

Q5: What is the HS Code for the tower crane travelling mechanism?

A5: The international HS Code (Customs Code) for ordering and shipping this product is 8431499900.

Q6: How does the travelling chassis work on the construction site?

A6: The chassis structure supports the mast sections and ballast blocks while riding on steel rails laid on the ground. Powered drive units move the entire crane structure along the track safely, offering strong stability, load distribution, and structural integrity during movement.
