OLI Vibration Solutions are used for concrete compacting, the manufacturer can offer External / Internal High Frequency Electric Vibrators as well as Pneumatic Vibrators for industrial use. These vibrators can be used for precast concrete production, ready mix concrete production, dry mix building material, asphalt mixing. We offer complete vibration solutions for Precast Manufacturers, Contractors and Concrete Industry.
Poker Vibrators & Convertors
OLI High Frequency Concrete Vibrators (Pokers) and Converters in a variety of models and options for compaction of fresh concrete on building sites.
The detailing should have such provision that vibrating head passes through the reinforcement. The spacing of bars should be detailed properly. Reinforcement can be grouped to have more space to permit vibrator pass through the gap freely. But the grouping width must be less than 25 cm and a spacing of 7.5 cm has to be provided between two groups. In individual group the bar spacing can be reduced up to 2/3 of nominal coarse aggregate size
We have already known about different forms of vibration techniques for concrete. Formwork vibrators are special type of vibrators that is applied externally to concrete i.e. not applied directly to concrete.
This type of vibrator is suitable for casting concrete in thin walls, columns and in construction of precast units. Clamps are used to attach the machine to the formwork externally. The aim is to provide vibration to concrete near shutters. The congestion in penetrating vibrator head require such machine and in thin sections where only surface vibration provides full vibration to concrete. The congestion situations includes where lateral ties, spacers and regular longitudinal reinforcement produce a impossible condition to provide usual internal vibration to concrete. This formwork vibration produces an excellent finishing surface of concrete.
Precast Concrete Table Vibrators
Vibrating Tables are designed and fabricated to suit the specific needs of your application.
Your table can be powered by
- Electric High Frequency Vibrators
- Pneumatic High Frequency Vibrators
OLI Concrete Table Vibrators are powerful enough to move even low-slump concrete, reduce casting time, and reduce the number and severity of surface imperfections. OLI vibrators are easy to move between tables to save you time and money!
External Industrial Motovibrators
OLI, ranks among the world’s leading manufacturers of External Electric Vibrators for industrial use. Providing from 20 to 26,000 kg of centrifugal force with 2, 4, 6 or 8 poles, the standard range of MVE External Electric Motovibrators is suitable for all kinds of vibrating equipment virtually in all industries. The Motovibrators come with single phase, three-phase or DC motor with ATEX ExII3D and ETL, Class II, Division 2 certification for application in the presence of potentially flammable dusts in hazardous environments.
MVE External Electric Motovibrators can be used as flow aids, on hoppers or silos to improve material discharge, or as drives on vibrating machines for several purposes such as conveying, screening, sizing, or compacting in a variety of industries.When the MVE is switched on a sinusoidal centrifugal force is provided by rotation of the eccentric weights. With only one MVE fitted on a vibrating machine a rotating force is provided resulting in a circular movement of the machine. Two counter-rotating MVE fitted in parallel on the same machine provide a linear force resulting in a linear movement of the machine. The requirement of circular or linear movement depends on the application.
