37KW Variable-Frequency Crawler Wire Saw Machine for Reinforced Concrete Cutting
CAHARD 37KW variable-frequency crawler wire saw machine is developed for reinforced concrete cutting, structural modification and demolition projects where a higher-power cutting configuration, adjustable main-drive speed and crawler-based machine movement are useful for the jobsite setup.
The machine combines a 37KW electric wire drive with variable-frequency speed control, wireless remote control and a battery-powered crawler chassis. It supports a maximum diamond wire linear speed of 25.5 m/s and a maximum 500 mm drive wheel.
37KW Variable-Speed Cutting Configuration
The 37KW power level is intended for reinforced concrete cutting projects with greater cutting workload than lower-power crawler configurations.
Main-drive speed can be adjusted according to actual cutting requirements, allowing the operator to adapt the machine to different reinforced concrete conditions and diamond wire configurations.
The reference average cutting efficiency is 5 m²/h. Actual output depends on concrete strength, reinforcement level, cutting dimensions, diamond wire specification and site operating conditions.
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.
Wireless remote control provides a practical control method for machine operation from a suitable working position on the jobsite.
Typical Applications & Model Selection
- Reinforced concrete wall cutting
- Concrete beam and column cutting
- Foundation and structural concrete cutting
- Structural modification projects
- Building renovation and structural demolition
Final machine suitability should be evaluated according to concrete strength, reinforcement level, structure dimensions, cutting workload, site access, available working space and diamond wire specification.
Which Crawler Wire Saw Configuration Should You Choose?
- 22KW fixed-frequency crawler: suitable when crawler movement is required and fixed main-drive speed is sufficient.
- 22KW variable-frequency crawler: suitable when adjustable main-drive speed is required but a 22KW power level is sufficient.
- 37KW variable-frequency crawler: choose this model when the project requires both adjustable main-drive speed and a higher 37KW power level together with crawler movement or crawler-assisted wire retraction.
- 55KW variable-frequency crawler: can be considered when the project requires a higher power level than the 37KW configuration.
If 37KW variable-frequency cutting is required but crawler travel is not needed, a non-crawler 37KW wire saw configuration may also be considered.
