While the Extruder is the heart of the Spiroll Hollow Core System, additional equipment is essential to transport the concrete mix from the batching plant to the Extruder.

Delivery of the concrete must be carefully thought out so that the Extruder doesn't run out of mix and slow down production. Several methods of concrete delivery can be used such as overhead cranes, fork lifts etc., however the best method is the Concrete Distribution System (CDS).

The CDS is a smart crane concept which was designed 10 years ago. It is a modular design based on standard crane components that allows great freedom in lifting capacities and speeds.

This System uses a self-propelled Skip to receive concrete from the batching plant and deliver it into the Extruder hopper.

Operation

1. The CDS is operated by a touch screen, which is mounted at ground level. The operator selects the type of hollowcore that is to be produced.

2. The operator switches to auto mode (on the radio remote unit) and the crane will automatically lift the skip and travel towards the filling station.

3. The hoisting unit automatically lowers the skip into the filling station and waits for the signal that skip has been filled.

4. After the signal the skip will be automatically lifted and the crane and crab move toward the Extruder.

5. As the crane and crab reach the Extruder the skip will automatically lower to the required level.

6. The operator must switch to manual operation and fill the casting machine by the remote control.

7. After the skip has been emptied the operator starts the automatic sequence again.

Features

• Modular Design - flexible lifting capacities and speed of operation.
• Ease of Service - are standard parts available worldwide.
• All movements controlled by inverters - reducing wear on brakes, ropes and mechanical parts.
• Touch-screen - operator can easily select the required program for automatic operations.
• Bucket can be lowered to ground level
• The hoisting-unit has a high safety level; the skip hangs in 4 separate ropes.
• Guiding system that stops the skip hitting the beams

Advantages

• The CDS will cut labour costs
• The CDS will increase production capacity
• Skip can be placed on an existing crane track
• No additional crane track for a bullet bucket is necessary
• The system is easy to program
• The system is easy to maintain
• The Skip is easy to clean on floor level
• The CDS doesn't interfere with other machinery on the ground
• The CDS can be ultilised to lift Production Machinery
• Working with this system will improve the safety in the plant

Specifications

The standard electrically operated Automatic Concrete Distribution System is designed according to the following specifications: -

• Lifting capacity : max. 2m³ of concrete
• Span : ± 15m
• Bucket Hoisting speed : 0-10 m per min.
• Crab traveling speed : 0-31.5 m per min.
• Crane traveling speed : 0-100 m per min.
• Lifting height : max. 6.5m
• Skip capacity : 2m³ of concrete

Optional Extras

• An extra hoisting unit can be provided to adapt the system to lift the Extruder & other production equipment.
• Two extra hoisting units can also be provided to use the crane to lift the hollowcore slabs.
• The crane can be installed with a modem, so that software can be serviced and changed online.
• If there are two or more cranes on the track an anti-collision system can be installed.
• The system can be equipped with an anti-sway option.
• Depending on the existing facilities a filling station can be provided & installed.

If you have an existing factory and looking at the feasibility of adding the CDS to it then please ensure you also include the following details: -

• Drawings of the layout of your production plant
• Location of the Batching Plant
• Number of the Casting Beds
• Length of the Casting Beds
• Details on existing overhead cranes
• Available Headroom
