Shanghe Crawler Placing Boom
A crawler concrete placing boom is a track-mounted, self-propelled machine that delivers concrete with precision in confined spaces and over rough terrain. Its compact design and high mobility make it the ideal solution for hard-to-access construction sites.

Key Features
Conquer Any Site Challenge with Intelligent Design
Work on Unsteady Ground: Automatic leveling outriggers and a balanced chassis provide a stable platform for continuous pouring, even on uneven surfaces.
Go Anywhere Mobility: Motorized rubber tracks and hydraulic suspension tackle rough ground, mud, and steep slopes, getting the boom exactly where you need it.
Fit in Tight Spaces: A compact footprint and low profile allow access to confined areas like tunnels, basements, and dense urban sites.
Power Your Way: Choose from dual power sources (engine/electric) for seamless transition between outdoor power and zero-emission indoor operation.
Place with Pinpoint Accuracy: The R-shaped, multi-section boom folds compactly and rotates 360°, delivering concrete with precision and speed, reducing labor costs.
Command with Confidence: A full-function wireless remote allows operators to control the boom from the safest and most optimal vantage point.
Main Applications
Crawler concrete placing booms are engineered to excel in the most challenging environments, making them the preferred choice for critical projects such as:
- Tunnels & Underground Construction
- Dam & Retaining Wall Construction
- Complex Foundations & Slab Pours
- Confined Urban & Indoor Sites
- Industrial & Factory Floors
