Gasoline Concrete Vibrators

Gasoline Concrete Vibrators

The VMG Series are Viber® Gasoline Power Units, which connect to standard flex drives (shafts) and vibrating heads used in concrete construction. VMG Models use Four-Cycle Gasoline Engines to produce up to 12,670 rpm and 2.5 horsepower. Four-Cycle motors use unleaded gasoline – no mixing of oil and gas is necessary. The VMG-2500BP develops 2.5 horsepower and is compatible with shaft lengths up to 35' (10.7 m) (or longer if care is used to prevent tight bends in the flex drive) and heads up to 2½" (63.5 mm) diameter. The largest Vibrator Head of 2½" attached to the VMG-2500BP model produces an output of 1,874 force pounds (8.34 kN), with a Radius of Action of 24" (610 mm), and a .08" (2 mm) Amplitude Peak-to-Peak. Please review the performance data for details.

All VMG models connect to Viber's standard flexible shafts and vibrating heads and are fully interchangeable with our electric or pneumatic vibrators; unlike competitors′ gasoline vibrators which may require special flex-drives or connectors. This provides exceptional flexibility and greatly reduces the amount of the contractor's inventory.

Advantages of the VMG Gasoline Concrete Vibrators:

  • Rugged Design - Reliable Brand Name Engines and custom-designed backpack frames using all metal components.
  • Portable - whether you choose handheld or backpack mounted engines, no air hoses or electric cords to get tangled up on the job site.
  • Backpack mounted engines swivel full 180° allowing the flexible drive to be more easily pushed behind the operator as the vibrating head is pulled from the concrete. “Tight swivel” bushing prevents motor from moving excessively as the operator changes positions.
  • Four-Cycle Engines - meets or exceeds environmental standards. No mixing of oil and gasoline is necessary.
  • VMG Series Power Units are available in two engine sizes and several models to be compatible with a wide range of Vibrating Heads.
  • Centrifugal Clutch Design - for improved performance and safety in all VMG gasoline vibrators. The centrifugal clutch allows the operator to stop the vibration when the head is pulled from the pour. The clutch disengages the flex-drive and stops rotation of the vibrating head. This reduces the chance of the vibrating head being operated outside the concrete pour, which can damage the high-speed bearings. This feature also protects the concrete forms from damage.
  • Conveniently located multi-function throttle control - allows operator to adjust speed of vibration for varying conditions during a pour.
  • Easy to Service - easily accessible repair parts make it simple to keep your VMG Vibrator up and running.
  • Built-in kill switch - immediately shuts off engine.
  • Flex Shaft Extended Lengths - The flexible drives can be coupled together using our coupling to extend them up to 35 feet (10.7 m) or beyond, but care must be used to prevent tight bends in the flex drive and also total weight of the system must be considered.
  • Components Completely Interchangeable - Gasoline vibrators use all our standard flex drives and heads. All parts have identical fittings so they can be paired with any size flex drive and head. If you stock the pneumatic VMP or the electric VMK, the flex drives and heads used with those models can be used with your VMG gasoline vibrator engine. The interchangeability provides exceptional flexibility and greatly reduces the amount of the contractor's inventory.
  • Built-in Quick Disconnect makes it easy to switch drives or heads.
  • Viber Vibrators Color-Coded Smart!Parts system takes the guesswork out of matching Vibrator Heads and Motors. See the "Smart!Parts Selection Guide".

Accessories:

  • Bearingless, cool-running coupling connects one Flexible Drive to another. You can easily extend our Flex Drive reach to 35 feet (10.7 m) or more. Longer lengths can be assembled, but tend to get quite heavy ~ approximately 100 lb (45 kg) for 100 ft (30 m). Use caution and avoid sharp bends in the Flex Drive, which will cause excessive wear on the drive and will slow down the engine performance.
  • VQDD Drive Fitting - Order the quick disconnect drive fitting (VQDD) for the flex drive or order flex drives with a drive fitting already attached. The VQDD screws onto the flex drive, which then connects it to the VMP.
