Services
We provide a comprehensive range of tailored services to support hollowcore production together with design and manufacturing support for prestressed precast concrete products.
  • Prestressing Training
  • Consultancy Services
  • Stressing Services
  • Grip Cleaning & Inspection

Turnkey Plants
Spiroll deliver total solutions for start-ups and comprehensive hollowcore factories providing machinery and support that achieves a quick payback. As well as supporting a low cost entry strategy, our solutions provide provision for growth enabling manufacturers to increase production capacity in line with demand.

Even mobile hollowcore plant set-ups can be offered to manufacture directly on the construction site. This is a cost effective option which can be offered to suit large volume projects or where the remoteness of the site does not offer access to existing hollowcore manufacturers.

Start-Up Hollowcore
Spiroll can provide all the support necessary to start a hollowcore facility without having to outlay a large capital investment. The aim is to have a staged investment with progressive development funded from the sales and future market growth of product.

Universal Extruder

The Universal Extruder is the heart of our hollowcore production system. Its unique design ensures that production is low cost, extremely reliable and the finished hollowcore is of the highest quality. The functional design means it very easy to use, set-up and maintain.The Extruder is unique as it works with auger drive combined with a 9000rpm high frequency vibration system. It produces hollowcore slabs with early strengths; consistent high quality finishes; low cement content; high load bearing capacities; excellent strand bond and low camber. The Extruder requires one man to run the machine on the production bed and once it has been set-up correctly it simply requires the mix to be put in the hopper to begin production. The extruder can manufacture the full range of hollowcore slab depths from 150mm (6”) to 400mm (16”). The unique quick change power unit takes just 5 minutes to swap from one cassette depth to another. The extruder makes hollowcore slabs suitable for both floor and wall panel applications.The machine comes with an independent wire/strand guide trolley to ensure correct positioning of prestress wires/strands and reduces resistance to movement ultimately improving finished product quality and increasing the working life of wearing components in the compaction chamber. The same effort that feeds the concrete mix through the machine and forms it into the final precast slab also provides the motivation to drive the extruder along the bed. This natural process propels the extruder along the casting bed and allows the compacted concrete to reach the required density.The Spiroll system uses an extremely dry concrete mix and less cement than other machines (typically a water/cement ratio of approximately 0.3). Due to the intense high frequency vibrations and pressure within the machine the concrete mix is 'plasticised' during the short time that it is passed through the extruder which allows it to be moulded and formed into the required section. The formed slab then reverts to its 'dry' state and reaches such a high density that it is possible to stand on the slab immediately after the extrusion process. After a period of natural or accelerated curing, the slabs are then cut to length, stripped from the casting bed and transported to the storage area.The casting beds are then cleaned, a release agent is applied and high tensile steel strands are located in position for the automatic extrusion process to begin again. Normally the entire production takes place over a 24-hour cycle.

Multi-Angle Saw

The Spiroll Multi-Angle Saw is designed for cutting the slabs directly on the production beds. The saw can cut any angle from 0-90 degrees in the hollowcore slabs. It can perform large skews and shallow off sets and also drive long cuts/rips down the entire length of the slab. The saws are designed to be used in an aggressive working environment. They are extremely robust and very easy to maintain with off the shelf spare parts. The frames are strong and give excellent stability which is very important to maximise blade life.The operator sits on a sprung seat in the cabin and controls all the movements by means of two pilot operated hydraulic joysticks which maximise comfort and provide close control. The operator has a clear unobstructed view of the cutting point on the slab. The blade head mechanism is up in the air away from the cutting point so that no spray and contaminants can get in the moving parts. All the hydraulic and electrical components are easy to access which also helps with minimal maintenance downtime.The saw head operates on a precision slide way movement running on the same linear bearing rails used in CNC milling machines. The saw head cuts using a vertical plunge movement. This allows high precision movement; minimal vibration and minimses the distance required between the casting beds. To ensure accurate cutting we have a digital encoder accurate with in +/- 0.1 degrees giving the required angle on a digital readout within the control cabin. There is also a laser marker which projects a line on the cutting point on the slab. These features make it easier for the operator to line the blade and cut the required angle in the slab. The saws are very efficient and have a fast driving and cutting speed. There is a highly efficient blade drive mechanism as the blade drive motor is mounted directly on the cutting head. This minimises the reduction in lose of energy due to friction and inefficiencies in power transmission.The saws can be easily set-up to be used with a range of diamond blades from 800mm – 1300mm in diameter. This ensures you use the optimum blade depending on the maximum depth of precast product. The saw has a CCTV system so that the operator can see in front of the hydraulic cable reels where the view is restricted. The saw can also be supplied complete with two hydraulic cable reelers for power and water. Each reeler would be supplied complete with 130 metres of cable/hose as standard (maximum length 180 metres).The saw can be designed/built to work in conjunction with any existing type of casting bed.

Crosscut Saw

The Crosscut Saw is specifically designed for cutting 90 degree crosscuts in the hollowcore slabs. It provides a fast, reliable and economical cutting solution. The standard saw cuts up to 400mm deep hollowcore but we also provide a conversion kit for slabs up to 500mm deep. It is very easy set the saw to use a range of diamond blades from 900mm to 1300mm in diameter. This ensures you use the optimum blade depending on the maximum depth of precast product.The operator sits on a sprung seat in the cabin and controls all the movements by means of two pilot operated hydraulic joysticks which maximise comfort and provide close control.
