Service Details:

A crawler crane is a type of heavy-duty lifting machine commonly used in construction projects for handling extremely heavy loads. It is mounted on a set of tracks (called crawlers) instead of wheels, which gives it excellent stability and mobility on rough or uneven terrain.

• Tracked Undercarriage: Unlike wheeled cranes, crawler cranes move on tracks, allowing them to operate on soft ground without sinking.
• High Lifting Capacity: They can lift very heavy loads, often ranging from dozens to hundreds of tons.
• 360-Degree Rotation: The upper structure (house) can rotate fully, enabling flexible lifting and placement of materials.
• Lattice Boom: Most crawler cranes use a long, lattice-style boom that provides strength while keeping the structure lightweight.
• Self-Assembly: Many crawler cranes can assemble and disassemble themselves on-site without needing another crane.

• Excellent stability without the need for outriggers
• Can move around the job site with a load (in some cases)
• Ideal for large-scale construction projects like bridges, dams, and high-rise buildings

• Slow movement compared to wheeled cranes
• Difficult and costly to transport between sites
• Requires significant space for setup and operation

• Infrastructure projects (bridges, highways)
• Heavy industrial construction
• Wind turbine installation
• Large-scale building projects
