Heavy Duty Concrete Vibrator for sale

The frame of the PortaVibe Backpack is made from welded aluminium. This gives the vibrator added strength and durability, while at the same time keeping it lightweight for the wearer. The PortaVibe’s longevity is even more of a guarantee thanks to the 44 mm hardened steel head, ensuring this tool will last a long time. It’s also easy to use thanks to the simple Honda GX35 engine, as well as a control arm that lets you easily change the machine’s rpm or hit the emergency shut-off if needed.

Comfort and ergonomics are extremely important when using a machine that has to be worn – after all, you don’t want to be uncomfortable while carrying around such a big tool. That’s why Flextool took the time and care to incorporate as many features as possible, so that your concrete vibrating experience is enjoyable. Vibration isolators in the base of the machine, as well as a rubber sleeve for the flexshaft, reduce the amount of vibrations you feel while you work. Because of this, you can keep a steady hand and make sure you get the results you want, and aren’t bothered by lots of vibrating.

Additionally, the swivel base will help to reduce back strain, as will the even weight distribution of the harness itself. This four point adjustable harness has breathable padding for even more comfort. It’s also made of a heavy duty nylon fabric, which not only gives the PortaVibe Backpack more strength, but it’s also easy to clean. So, maintenance of this Flextool concrete vibrator is incredibly simple, and the machine will minimise fatigue and strain while you’re wearing it. There’s even a small storage pouch at the top of the machine, so you can securely store personal items and bring them with you!
