22KW Fixed-Frequency Crawler Wire Saw Machine for Reinforced Concrete Cutting
CAHARD 22KW fixed-frequency crawler wire saw machine is designed for reinforced concrete cutting, structural modification and demolition projects where crawler movement and remote-controlled wire retraction are useful for the project setup.
The machine combines a 22KW electric wire drive with electric wire tensioning, wireless remote control and a battery-powered crawler chassis. The cutting system supports a maximum diamond wire linear speed of 25.5 m/s and a maximum 500 mm drive wheel.
Crawler Movement & Wire Handling
The crawler chassis supports battery-powered movement using a 48V lead-acid battery system, allowing the machine to be repositioned without relying on the main cutting power supply for crawler travel.
The crawler travel function supports remotely controlled wire retraction, combining machine movement and wire handling in one crawler-based system.
The machine uses electric wire drive and electric wire tensioning for the cutting system.
The main motor operates at fixed speed. For projects that require adjustable main-drive speed, a variable-frequency crawler wire saw configuration should be considered.
Typical Applications & Project Fit
- Reinforced concrete wall cutting
- Concrete beam and column cutting
- Foundation and structural concrete cutting
- Structural modification projects
- Building renovation and demolition
When to Choose a Crawler Wire Saw
This model is suitable for projects where machine movement within the working area and crawler-assisted wire retraction are useful, while a 22KW fixed-speed cutting configuration is sufficient for the required workload.
Final machine suitability should be evaluated according to concrete strength, reinforcement level, structure dimensions, site access, available working space, cutting workload and diamond wire specification.
