In the rapidly evolving world of 3D concrete printing (3DCP), material consistency and efficient workflow are crucial. The Wolfpack 3DCP Crawling Barrel Mixer is engineered precisely for this challenge — automating and simplifying the mixing process, while delivering uniform, high-quality concrete or mortar. This is not just any mixer: it’s a self-propelled, low-footprint, tracked mixer that brings power and mobility to demanding construction sites.
Why the Crawling Barrel Mixer Is a Game-Changer
1. Mobility Meets Power
Equipped with a hydraulic track drive, the mixer can move itself around the job site — no need for heavy lifting or external vehicles just to reposition
Its compact dimensions and tracked system make it ideal for rugged, confined, or uneven terrain, which is often the case in 3DCP construction projects.
2. High Capacity, Precise Mixing
With a 300 L mixing drum, this mixer balances capacity and manageability
The built-in hydraulic motor (13.5 HP) ensures strong, consistent mixing — helping to maintain a uniform concrete or mortar mixture, which is essential for successful layer-by-layer 3D printing.
3. Self-Loading & Dumping Mechanism
This mixer is not just about mixing. It self-loads, reducing manual labor, and features a hydraulic dumping system, making it easy to pour the mixed material exactly where needed
The hydraulic system also includes a cooling radiator, which helps in long runs of continuous operation.
4. Labor Efficiency & Safety
By automating the mixing process, the Crawling Barrel Mixer reduces the physical strain on workers. This leads to safer work conditions, less fatigue, and reduces the risk of human error in mixing proportions. Consistent mixes also mean fewer failed prints or weak layers, which is vital for structural integrity in 3DCP.
Comparison: Wolfpack Crawling Barrel Mixer vs Traditional Mixers
| Feature | Wolfpack Crawling Barrel Mixer | Traditional Stationary Concrete Mixer |
| Mobility | Self-propelled via hydraulic tracks | Usually fixed or requires separate transport |
| Mixing Volume | 300 L drum | Varies; could be similar or larger, but less mobile |
| Loading | Self-loading automatic system | Manual loading or external equipment required |
| Dumping | Hydraulic dumping system | Often manual tipping or fixed mechanisms |
| Labor Needs | Reduced labor, automated mixing | Higher manual labor, more supervision |
| Use Case | 3D printing sites, small-mid construction, remote | Large batch mixing, fixed jobs, traditional concrete works |
The Crawling Barrel Mixer stands out particularly for 3DCP applications, where you need consistent batches, mobility, and minimal interruption.
Applications & Use Cases
- 3D Construction Printing: Ideal for 3DCP work, giving you a reliable and consistent mix to feed into your print pump.
- Remote or Confined Job Sites: The tracked drive allows operation in areas with limited access.
- Small to Medium Pour Projects: Great for footings, walls, or printing segments where 300 L of mixed material is sufficient.
- Continuous Work: With self-loading and dumping, it supports extended on-site operations without frequent manual labor.
Buy or Rent Option
We understand that construction projects vary in scale and timeline. That’s why we offer the Crawling Barrel Mixer both for purchase and rental:
- Buy: For long-term projects, repeated prints, or permanent setups.
- Rent: Ideal for short-term construction, pilot 3DCP trials, or one-off printing jobs.
This flexibility helps you scale your operations cost-effectively — whether you’re just starting with 3DCP or ramping up.
The Crawling Barrel Mixer is a compact, self-propelled concrete mixer designed for efficiency and versatility. It integrates self-loading, rotary mixing, and hydraulic dumping, making it ideal for small-scale construction projects.
