22KW Variable-Frequency Crawler Wire Saw Machine for Reinforced Concrete Cutting
CAHARD 22KW variable-frequency crawler wire saw machine combines adjustable main-drive speed, electric wire drive and tensioning, battery-powered crawler travel, wireless remote control and crawler-assisted wire retraction for reinforced concrete cutting projects.
This model is designed for contractors who need a 22KW crawler wire saw configuration but also want adjustable main-drive speed for different cutting conditions. The machine provides a maximum wire linear speed of 25.5 m/s, supports a maximum 500 mm drive wheel and has a listed reference average cutting efficiency of 3 m²/h.
Variable-Frequency Control & Crawler Operation
The variable-frequency configuration allows the main motor speed to be adjusted according to cutting requirements, while the secondary motor supports forward and reverse movement with stepless speed adjustment.
The crawler platform uses a 48V lead-acid battery system for machine movement and repositioning on the jobsite.
The crawler platform supports wire retraction through crawler movement with wireless control.
Wire Cutting Performance
The listed maximum wire drive power is 22KW for reinforced concrete wire sawing applications.
Maximum listed diamond wire linear speed is 25.5 m/s.
The wire saw system supports a maximum drive wheel size of 500 mm.
Listed average cutting efficiency is 3 m²/h as a reference value.
Typical Applications & Model Selection
- Reinforced concrete wall cutting
- Concrete beam and column cutting
- Foundation and structural concrete cutting
- Structural modification projects
- Building renovation and concrete demolition
Final machine suitability depends on concrete strength, reinforcement level, structure dimensions, expected cutting workload, diamond wire specification, crawler movement requirements and actual site conditions.
Which Crawler Wire Saw Configuration Should You Choose?
| Configuration | Main-Drive Speed | Reference Average Cutting Efficiency | When to Consider |
|---|---|---|---|
| 22KW Fixed-Frequency Crawler | Fixed speed | 3 m²/h | When the 22KW power class is sufficient and adjustable main-drive speed is not required. |
| 22KW Variable-Frequency Crawler | Adjustable | 3 m²/h | When the 22KW power class is sufficient but adjustable main-drive speed is preferred for different cutting conditions. |
| 37KW Variable-Frequency Crawler | Adjustable | 5 m²/h | When a higher wire-drive power class and a higher listed reference cutting-efficiency level are required. |
The 22KW fixed-frequency and 22KW variable-frequency crawler models share the same listed maximum wire linear speed of 25.5 m/s and the same 3 m²/h reference average cutting efficiency. The main difference is adjustable main-drive speed, not a higher listed maximum wire speed or cutting-efficiency rating.
The 37KW crawler model also has a listed maximum wire linear speed of 25.5 m/s. Its main difference is the higher wire-drive power class and higher reference cutting-efficiency rating.
Final selection should be based on concrete strength, reinforcement level, cutting dimensions, expected workload and the required wire-drive power class.

Tell Us About Your Cutting Project
If you are considering a 22KW variable-frequency crawler wire saw machine, send us your cutting requirements and jobsite conditions. CAHARD can help evaluate whether the 22KW variable-frequency configuration or a higher-power crawler model is more suitable for your project.
Please provide the following information when possible:
- Material to be cut
- Concrete strength, if known
- Structure dimensions and cutting thickness
- Reinforcement condition
- Expected cutting volume or daily workload
- Jobsite movement and wire-retraction requirements
- Available working space and site access conditions
- Available 380 V power supply and required frequency: 50 Hz or 60 Hz
- Destination country / port
- Required quantity
- Whether diamond wire is also required
If diamond wire is required, please provide the cutting material, dimensions, reinforcement level and expected workload so we can recommend a suitable wire specification for the project.
