Different types of Concrete Slip Form Paver Machines

Concrete Slip Form Paver

Concrete slip form paver machines are used to pave construction works in which concrete is poured into a continuously moving form. The construction materials are continuously prepared and poured over the paving surface and the leveling is done simultaneously. The concrete slip form pavers machines are used for this type of topping. Concrete slip form pavers spread out, form and, depending on attachments, apply an initial finish to the surface of low-slump Portland cement concrete (PCC). These machines provide a continuous and seamless concrete pavement surface and by nature give a smooth surface, without having joints. There are several advantages achieved by availing this concrete slip form paver machines.

Advantages of concrete slip form paver machines

There are several advantages achieved by availing Slip form paver machines for your project, some of the advantages are-

  • The precision levels of the surfacing are very high
  • Makes use of low slump PCC
  • The entire operations are mechanized
  • Suited for a large area of Paving
  • Automatic width adjustments without unnecessary adjustments
  • Specially designed to manufacture continuous kerbs that are strong and appealing

Hybrid concrete slip form pavers

Modern hybrid offset slip form machines economical alternative system for steering regulation via string line. They are enhanced with Automatic 3D control systems. Even complex profile configurations can be created right on-site and within a short period. The system is based on GNSS (Global Navigation Satellite System) and assists with the automated paving of a wide variety of offset and inset profiles, such as concrete safety barriers on motorways or curbs for traffic islands. Depending on the paver model, the belt conveyor is available in different lengths and folding design. The auger conveyor is also available in different designs. And whether belt or auger conveyor: all settings, such as conveying speed, angle of incline, or position can be made at the mere push of a button. In offset application, mixer trucks deliver the concrete into the receiving hopper of the slip form paver. Transport to the mould is effected via a sewable belt or auger conveyor.

Offset concrete slip form pavers
The SP 60 series from Wirtgen offers flexible solutions for high-quality concrete paving, whether inset or offset.

Concrete slip form pavers for concrete slabs

With Inset slip form pavers, the large slip form paver for paving concrete slabs at widths of up to 16.00 m can be upgraded for two-layer paving in one single machine pass. Precise insertion of tie bars and dowel bars via self-loading dowel bar inserter (optional) enables concrete paving over reinforcing steel. The intelligent machine concept with hydraulic swing arms and worm gear steering makes the machine easy to transport and offers maximum flexibility in any job site situation. The paver may be equipped with a hydraulic or electric vibrator drive. In the standard design, it comes with 12 hydraulic connectors, but may be fitted with 18 or 24 electric connectors. As well, the separate hydraulic sidebar inserters may be mounted on the left, right or both sides of the machine.

Concrete texture slip form pavers

A new age texture/cure machine features a new walking end car with a curing tank. Frame sections can be added or removed by turning the tracks 90 degrees and walking the end car with the attached cure tank to the required width. The walkway and railway telescope with the walking end car. The texture curing machine offers a complete texture/cure solution for your large concrete paving job. Whether its heavy highway, airport or road paving, stand-alone Electric-over-hydraulic forward and reverse steering and grade control is sensored off the same string line as the paver. This provides ease of operation and accuracy in texturing and curing of the slab. Texturing assembly travels transversely across the width of the concrete slab. Texturing wire tine members are automatically pivoted to the trail at the end of each pass.

Technological modification in slip form machine models

The once seemingly huge problems of using slip-form methods to build reinforcement pavement are being solved with astonishing speed. The first pavement built with conventional distributed steel using the slip form method was laid in 1958 since then technological advancement has been done and modern machines are utilizing different systems for machine modification

Power Paver two-track concrete slip form – The paver designed to pave between 12’ (3.65m) and 27’ (8.23m) wide. The machine is designed around production and simplicity. The operator has an excellent view of all functions around the machine and its low center of gravity makes it easy to transport. Equipped with electronic sensors, easy to mount vibrators, and without bulky side-forms, operators can focus their time paving rather than setting up.

Heavy-duty, high production concrete slip form – The paver comes with hydraulic loading legs which extend to allow for easy loading and transport, coupled with the ability to change widths quickly. With this machine the operator can take over the previous day’s pour and start paving right off the header, eliminating gaps and blow-out and resulting in less handwork.

Concrete Slipform with a swivel-mounted conveyor belt – In this machine, the conveyor belt is available in various lengths and a folding version. Different versions of the auger conveyor are also available. Whether conveyor belt or auger – all of the settings such as conveyor speed, inclination angle, or position can be adjusted at the touch of a button. An additional transverse auger conveyor offers many benefits.

Concrete Slipform with automatic control – In this machine grade, adjustment and machine steering are controlled automatically (sensor and stringline), or manually from the operator’s control panel. Variable speed, motor-in head hydraulic vibrators are independently controlled and the same as used on big machines.


Control development will continue to be a focus of slip form paver design and operation to create smooth pavements. Road Building specs are continually being adjusted to closer tolerances and tighter specifications, which is pushing manufacturers to continually refine their products.
