GQ-M02 High Frequency Electric Internal Concrete Vibrator

Product Features:
Reinforced Steel Roll Cage: Welded from seamless steel tubing with a diameter exceeding 20mm and finished with an impact-resistant electrostatic coating, the cage serves as both a protective shield and a handle that allows for 360-degree gripping and handling.
High-Insulation Motor: Features a built-in Class H high-temperature-resistant all-copper coil, capable of withstanding instantaneous temperatures up to 180°C without burnout.
High-Performance Bearings: Utilizes high-precision bearings to ensure minimal radial runout of the motor output shaft during high-frequency vibration, significantly reducing energy loss.

Applications: Suitable for precast beam yards (T-beams, box girders), railway roadbeds, large-scale hydraulic dams, and nuclear power plant foundations. Its high-frequency vibration rapidly liquefies low-slump (stiff/dry) concrete.

Common Issues and Solutions
Issue: Roll cage connections loosen after prolonged use.
Solution: This is caused by metal fatigue resulting from high-frequency resonance; it is recommended to check and tighten bolts weekly and install spring washers.
Issue: Excessive sparking at the carbon brushes.
Solution: Check for the ingress of fine stone dust. Clean carbon deposits from the commutator surface and replace with genuine, high-hardness carbon brushes.

Important Precautions
Strictly prohibit operation without the roll cage installed or when the cage is severely deformed to prevent the motor housing from cracking due to direct impact.
Do not spray water directly into the motor air intake after get off work.
