Truck-mounted concrete pump 31 XXT

Overview
The 31 XXT is a truck-mounted concrete pump with a 5-part Z-fold distribution boom, designed for operations in confined or indoor environments thanks to short boom segments and low unfolding height. The LiDriveIn function permits safe entry into buildings during normal operation with the boom folded in front of the cab.

Main attributes

• Vehicle type: Truck-mounted concrete pump
• Vertical reach: 30.6 m
• Unfolding height: 5.40 m
• Horizontal reach: 26.4 m
• End hose length: 4 m
• Supporting system: XXT pivoting support

Key features

• 5-part distribution boom in Z-folding: short arm segments optimized for indoor use and good slip properties.
• LiDriveIn function: allows entry into halls with the boom folded in front of the cab; enables passage through openings from 4 m height and straightforward unfolding inside due to low unfolding height (5.4 m).
• XXT pivoting support: versatile solution for tight-space support; front support can be swivelled forward of the cab enabling work across the cab even with narrow support footprint.
• Powerbloc drive unit: compact integrated drive with smooth running; integrates hydraulic switching and measuring elements without a separate control block.
• XXA stability assistance system: electronic monitoring of partial support areas for additional support options and safe operation.
• Semi-closed oil circuit (HCC): ensures continuous and reliable hydraulic power combining advantages of open and closed circuits.
• Practical hose and piping storage: storage solutions adapted to customer requirements for safe and ergonomic stowage.

Applications

• Indoor concrete placing where low unfolding height and short boom arms are required.
• Jobs requiring entry into buildings or constrained access with limited headroom.
• Projects needing flexible support configurations and electronically monitored partial support.
