22KW Variable-Frequency Crawler Wire Saw Machine

Product Overview

CAHARD 22KW variable-frequency crawler wire saw machine is designed for reinforced concrete cutting, structural modification and demolition projects where crawler mobility, crawler-assisted wire retraction and adjustable main-drive speed are required.

The machine provides a maximum wire drive power of 22KW and combines electric wire tensioning, 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 drive wheel size of 500 mm. The main-drive speed can be adjusted to suit different cutting requirements.

Crawler Wire Saw Machine Applications

Reinforced Concrete Wall Cutting

Suitable for cutting reinforced concrete walls in building renovation, structural modification and demolition projects.

Concrete Beam & Column Cutting

Suitable for cutting reinforced concrete beams and columns during structural modification and demolition work.

Foundation & Structural Concrete Cutting

Suitable for cutting concrete foundations and other structural concrete sections with diamond wire.

Structural Modification & Building Renovation

Suitable for reinforced concrete cutting during structural modification and building renovation projects.

Concrete Demolition

Suitable for reinforced concrete cutting during concrete demolition work.

22KW Variable-Frequency Crawler Wire Saw Machine Technical Specifications

Note: The 3 m²/h cutting efficiency is a reference value. Actual cutting efficiency may vary depending on concrete strength, reinforcement level, cutting dimensions, diamond wire specification and site operating conditions.

Power Supply Note: Please confirm that 380 V power is available on site and whether 50 Hz or 60 Hz is required before ordering.

Standard Accessories

22KW Variable-Frequency Crawler Wire Saw Machine Features

22KW Maximum Wire Drive Power

Provides a maximum wire drive power of 22KW for reinforced concrete cutting, structural modification and demolition applications.

Electric Wire Tensioning

The electric wire tensioning system has a maximum specified power of 22KW.

Variable-Frequency Main Drive

The variable-frequency configuration allows the main-drive speed to be adjusted to suit different cutting requirements and conditions.

Battery-Powered Crawler Movement

The crawler chassis uses a 48 V lead-acid battery system for machine travel, allowing the machine to be repositioned within the working area without relying on the main cutting power supply for crawler movement.

Crawler-Assisted Wire Retraction

The crawler system can also be used for remotely controlled wire retraction, combining machine travel and wire handling in a single system.

Wireless Remote Control

Wireless remote control allows the operator to control the machine from a suitable working position during cutting.

25.5 m/s Maximum Wire Linear Speed

Supports a maximum diamond wire linear speed of 25.5 m/s.

500 mm Maximum Drive Wheel

Supports a maximum drive wheel size of 500 mm.

Stepless Secondary Motor Control

The secondary motor supports forward and reverse movement with stepless speed adjustment, while the variable-frequency main drive allows the main-drive speed to be adjusted as required.

When to Choose the Variable-Frequency Crawler Model

This 22KW variable-frequency crawler model is suitable for reinforced concrete cutting projects that require crawler movement, crawler-assisted wire retraction and adjustable main-drive speed.

Compared with the fixed-frequency crawler model, the main difference is adjustable main-drive speed rather than higher listed power, maximum wire speed or reference cutting efficiency. If fixed-speed operation is sufficient, the 22KW fixed-frequency crawler wire saw can be considered. Final model selection should also take into account concrete strength, reinforcement level, structure dimensions, cutting workload, site access, available working space and diamond wire specification.

Tell Us About Your Reinforced Concrete Cutting Project

To help CAHARD evaluate your application and recommend a suitable crawler wire saw configuration, please provide the following information when possible:

• Concrete type or material to be cut
• Concrete strength, if known
• Reinforcement level
• Structure type and dimensions
• Concrete thickness or cutting cross-section
• Estimated cutting workload
• Site access conditions
• Available working space
• Whether crawler movement is required on site
• Whether crawler-assisted wire retraction is required
• Whether 380 V power is available on site and whether 50 Hz or 60 Hz is required
• Diamond wire specification, if already selected
• Whether adjustable main-drive speed is required
• Destination country / port
• Required quantity

If diamond wire is also required, please provide the concrete and reinforcement details so CAHARD can recommend a suitable wire configuration.

CAHARD can help evaluate whether this 22KW variable-frequency crawler wire saw machine is suitable for your reinforced concrete cutting, machine movement and wire handling requirements.
