Concrete Vibrator GEKO WG-527 850W, Head Diameter 35 mm, 2 m Shaft, Double-Ended Plug

Electric concrete vibrator GEKO WG-527 with an 850 W motor and a 35 mm head diameter is designed to compact fresh concrete and eliminate entrapped air. The tool has a 2 m flexible shaft and a double-ended plug for reliable power connection, allowing continuous operation on construction sites. It is suitable for finishing slabs, consolidating columns and beams, and for use in narrow formwork where consistent vibration is required to achieve uniform concrete density.

Advantages

The GEKO WG-527 combines a high-power 850 W motor with a compact 35 mm vibrator head to provide effective consolidation in medium to thin concrete sections. Its 2 m shaft gives access to confined areas while maintaining operator comfort, and the robust attachment ensures stable performance during prolonged use. The double-ended plug simplifies connection and replacement of the shaft assembly, and the overall construction is engineered for durability and consistent vibration frequency.

Suitable for

• Compacting fresh concrete in floor slabs and pavements
• Consolidating concrete in columns, beams and small formwork
• Removing air pockets and improving surface finish prior to curing
• On-site concrete work in renovation and repair projects

Key specifications

• Motor power: 850 W
• Vibrator head diameter: 35 mm
• Shaft length: 2 m (flexible shaft)
• Power connection: double-ended plug for reliable electrical contact
• Application: internal consolidation of freshly poured concrete

How to use

Insert the vibrator head vertically into the fresh concrete at regular intervals, typically every 20–30 cm depending on element thickness. Hold the shaft steady and allow the tool to run until visible concrete settlement and air release stop, then withdraw the head slowly while maintaining vibration to avoid voids. For deep sections, work in overlapping positions moving progressively across the formwork to ensure even compaction. Ensure the power supply matches the tool specifications and check the shaft and plug connection before each use.

Usage recommendations

Use personal protective equipment, including gloves, eye protection and hearing protection. Avoid continuous operation beyond manufacturer duty cycles; allow short rests during extended work to prevent overheating. Clean the vibrator head and shaft after each use to remove hardened concrete and inspect the flexible shaft and connections regularly for wear or damage.
