Vibrating beams
Vibrating beam for levelling concrete.
The DTA super beam screed compacts and levels large concrete surfaces using rigid, hard-wearing light-alloy beams. A stressing bar runs through each beam, so two screws are enough to pre-stress out any sag and hold an accurate level. A single vibrator unit transfers across every beam length in the range, giving up to 200 mm of penetration at 3,000 rpm, and optional outriggers with large rubber-covered rollers glide along rail systems while damping vibration. Available in 400V, petrol, or 42V/200Hz on request.

A stressing bar runs through each DTA beam, so just two screws are enough to pre-stress out any sag and hold an accurate level across the span. The vibrator unit penetrates concrete up to 200 mm deep at 3,000 rpm, which is what levels and compacts large surfaces in a single pass.
Yes — a single vibrator unit transfers across every DTA beam length in the range, from 3.2 to 7.2 m (frame weight 57–98 kg, excl. vibrating unit). It's standard in 400V/3-phase/50Hz or 4-stroke Honda petrol, with 42V/3-phase/200Hz available on request.
Every Lievers machine, including the DTA, comes with a one-year warranty. Register your machine and you get a second year on top — two years of cover in total.
Lievers machines are backed by a network of local service points with spare parts on hand, so maintenance and repairs on your DTA stay close to the job. Get in touch and we'll point you to the nearest one.
