FRAME CONSTRUCTION
Construction industry also relies on Compressed air. Portable air compressors are used in this industry. Many pneumatic tools, drills and jack hammer are using compressed air.
Uses of compressed air in the Construction industry includes:
- Concrete breakers (jack hammer): These are used for breaking up road surfaces. They consume air at a rate of 10-20 m3/min, and typically weigh 15-40 kg. They are flexible in terms of being able to be fitted with a variety of heads for different requirements.
- Pneumatic picks: Similar to concrete breakers but smaller and lighter. Typically they have an air consumption rate of around 6 m3/min.
- Backfill rammers: Used for backfilling trenches and have a consumption rate of around 10 m3/min.
- Chipping, caulking, riveting hammers: Small, lightweight tools with low air consumption of around 0.5 m3/min.
- Hammer drills: Used for wet or dry drilling, and commonly used for drilling rock or concrete.
