Hollow core slabs for floors and walls are normally produced on 120 ~ 150 m long steel casting beds using slide forming techniques.
The slide former disperses concrete from distribution devices one layer after another into a mould as it moves along the casting bed while being pulled by a sling winder. Each layer is compacted by the high frequency vibrating stages of the slide former. Achievable average output is about 864 – 1,080 square metres per 8 – 10 hour shift.
Changeover to another thickness profile is easily made by changing the slide forming mould in about 2 hours. Slabs can be saw cut on the casting bed as it cures overnight in just 18 – 24 hours.
Standard slide former unit consists of:
• Dimensions W1.9m x L6.3m x H2.7m with Lifting Point
• 3-Stage Compaction System with External Vibrators
• Concrete Hoppers with Gear Motors to Feed Concrete to Mould
• Motor Wound Drum for Electric Cable for 3-phase 380VAC, 50 Hz
• 4-Wheel Motor Gear Drive System
• Water Tank 100L
• Electric Control Panel (Excluding Power Section)
