WCH produces a wide range of equipments for the production of Precast Concrete:

Tradition - Technology - Quality - Productivity - Flexibility - Durability .

Batching Plants, with doser wall and Mixer with capacity to discharge 750 to

4500 liters of mixed concrete every 3 minutes .

Production Beds: We indicate metal or metal lined beds for a better finish on the inferior part.The length of the beds are between 100 and 200 meters, with a slope for water drainage, in numbers that permits the desired production with the sales demand, due to curing time for the cut (30 to 48 hours for natural curing and 8 to 10 hours for thermal curing). After cutting, the products are transferred to the stock or to the job site, where the final cure will be done.

Anchor Banks: calculated and executed for each client's needs.

Uncoiling Station and Container for packaging and organization of the prestressing steel rolls.

Distribution of Prestressing Steel:Draw Trolley, to distribute the prestressed steel on the production bed.

Cleaning, Olier, Wire Distribution Machine, to distribute wires, brush and oil the beds.

Prestressing: performed by Prestressing Equipment, monofilament system, with pre-tension and adhesion directly on the concrete, being a simple and safe operation.De-stressing: transfers prestressing loads from the Anchorage bank to the product through a Pump and Hydraulic Cylinders of simple action.

Cutting Machine:

Semi-Manual, Semi-Automatic, Automatic, Standard and Angular models.After initial cure and de-stressing the profiles are cut into the desired measures.

Transport: Gantry Crane or Single-Girder Overhead Crane of various sizes and

capacities.Transport Car used to transport two buckets, releasing the Single-

girder overhead crane for use.Set of Mechanical Grippers and Balance Beam.

Surface Finishing Machine:Used to seal to SLIPFORM-produced hollow-core and solid slabs with a decorative finish. With several devices that allow special finish designs.

Finishes:Exposed aggregate.

With total or partial substitution of the Slipformer Unit, several products are produced, including: Panels/Hollow-Core Slabs, Floor Slabs, T-Beams, Double-T (I), Piles and other products that can be made on flat beds.

The machine is composed of:Feed unit (silo): universal component that is placed over the Additional Caster and combines the electric and hydraulic command functions for concrete feeding. The connection between the Feed unit (Silo) and the Additional Caster uses electrical plugs and sockets, hydraulic push-pull couplings (quick connect) and a mechanical through fast link pins system.The Additional Caster defines the product and combines molding, vibrating and traction functions. The molder vibrates the product in the bed over the prestressing strands, leaving it ready for curing with minimum labor required and high productivity.

Technical specifications:

• Electro-hydraulic traction on all 4 wheels.• Two feed and compacting stages.• Section height regulator.• Production speed from 1.20 to 2.80 m/min depending on the section.• Front guide wires.

Panels/Hollow-Core Slabs, Floor Slabs, T-Beams, Double-T (I), Piles

SLIPFORMER Casting Machines Applications/benefits:

Hollow-core and solid slabs are widely used in commercial, industrial, and high-rise residential buildings due to the innumerous they offer:

• Uniform, high quality products, controlled by the industrial process.

• Lighter-weight products, resulting in savings in foundations and structures.

• Fast, easy assembly without forms, avoiding stoppages.

• Bracing and molds unnecessary.• Supported by: - Conventional concrete structures.

- Structural brickwork.

- Precast concrete or metal products.

• Good heat/sound insulation due to interior air pockets.

• Easy, economical transportation.

Hollow Core Slabs/Slabs:

Additional Caster for Prestressed T-Beams:

Prestressed Slabs (T-Beams):

•Simultaneous production of 8, 10 or 12 prestressed beams.

• Center height regulation up to 16 cm.

• Productivity ±1,200 linear meters/hour, with the 12 beam caster.

• Dry concrete (low slump), resulting in highly resistant pre-cast

sections (45-55 MPa / 6500–8000 psi).

• Versatility and speed for producing various sections.

• Low man/hour cost.

• Low maintenance costs.

• Operating flexibility.

Sandwich panels: made of latticed rebar, that will form the slab's reinforcement structure, cased with wyeths

Note:1 - Topper concrete consumption = Liters/m² Own weight = kg/m².2 - The sandwich panels do not consider concrete consumption for locking ribs. The prestressed slab does not use locking ribs.

These conditions may change according to the slab span or its weight.

Wider spans and less sag: Prestressed precast slabs cover wider spans while offering the same load with less final sag because of the prestressing applied to the joists.

Applications/Benefits:

•Reduced concrete consumption and labor.•Easy erection.•Effective and efficient use of highly-resistant materials (concrete and steel).•Sleeker, lighter sections, allowing more attractive structures.•Reduced total or partial building weight reduces the cost of foundations. •Lighter sections allow for reduced loads from seismic shocks.•More economical spans.•Better sag control.•Reduction of cracks.•Strict quality control.

Prestressed slabs are easy to assemble, requiring a minimum of rebar (distribution mesh) and do not require locking ribs or additional reinforcement.They are produced on 100 to 200 m polished concrete beds, with industrial flooring and foundation blocks for anchoring heads that are supported by the industrial floor to support the compression of the stressing. We supply technical plans for foundations and structural work for clients to carry out.

Materials consumption in erection: Based on a ceiling slab for a 5.5 m span and 100 kgf /m² load wi th dua l supports.

• Heights of 6 to 40 cm.• Productivity of up to 150 m²/hour(the production speed is changeable in agreement to the product).• Slabs/Hollow core slabs with 30 up to 50% of empty.• Dry concrete (slump 0 to 1) resulting in superior resistance (45-55 MPa / 6500-8000 psi). • Low man/hour cost.• Low maintenance cost.• Versatility and speed for producing various sections.
