The company supplies two systems for slipforming: Light (jacks with 3 & 6 tons capcity) and Heavy (jacks with 12 & 22 tons capacity).

Each jack is designed to be as versatile as possible in order to have equipment which can be used for a variety of project and applications.

Slipforming is a method of construction, which is used for building huge concrete towers and bridges. The term "slipform" refers to a moving form in which concrete is poured, and which moves continuously at a slow pace. The concrete that has been poured previously hardens as the form moves. This technique has also been implemented in construction.

It is a construction technique, which has been used for several years for the purpose of production of concrete structures. A huge variety of vertical structures such as bridge columns, towers, offshore platforms; and horizontal structures such as canal lining and rigid reinforced concrete pavement are slipformed. Besides vertical structures with uniform thickness, the said technique is also useful even if geometry of a structure or wall thickness varies. This technique is a continuous working operation, which needs proper supervision, supply of materials, and management. One must make sure to solve the problems occurring during this process. Compared to other techniques, slipforming consists of complex operations. Still, there are a number of advantages of implementing this technique.

The advantages of the slipform formwork are as follows:

1.      The construction speed increases, and thus projects are completed rapidly. This saves a considerable amount of time.

2.      As formwork is lifted with the help of hydraulic jacks, this technique requires minimal usage of a crane.

3.      As the slip formwork system requires the use of its own platforms for implementation of works, optimal quantity of scaffolding and work platforms is delivered. This helps in maintaining cleanliness and order at the construction site, as there is no unnecessary material that needs to be stored.

4.      This technique constitutes uniformity of wall sections with project drawings, and thus smooth wall surfaces are created.

5.      The speed of the working process reduces labor costs.

Bygging-Uddemann is a company that supplies two systems for slipforming, namely light jacks and heavy jacks. Each jack is designed to be as resourceful as possible, so that it can be used for a wide range of applications and project. All models of slipform jacks can be combines as they all have the same stroke.

Everything from the foundation to rooftop of tallest projects, installing steel reinforcement and pouring concrete becomes much faster and easier with the help of the system’s hydraulic jacks. In addition to this, the construction process can be controlled more efficiently to assure the best quality of finished cement structure.

Slip forming is modern and effective method of construction. It is used for constructing tall structures such as towers, bridges, chimneys, etc. During slipforming, concrete is poured into a continuously moving structure which can be very productive and cost effective for construction companies (Dr. Mohammed Ghonim, SLIP-FORM CONSTRUCTION, 2015). Slip form construction method requires the use of a wide variety of slipform jacks. These jacks help elevate the concrete form and working platform.

There are two important forms of slipforming: vertical and horizontal. In horizontal slipforming used for building pavements or traffic separation walls. Vertical construction is a popular choice for constructing tall structures. It provides many benefits to construction companies such as reduction in time, costs, labor and machinery use, etc. It can also provide a joint less and waterproof structure to add more durability. The following is a list of various aspects of slipforming.

Structure

The slipform rig includes three decks for effective and smooth constructions. The first level is used for facilitating placement of the concrete and installing steel. The second deck or the middle one is the main platform for working. It provides a platform for gates, ladders, and maintenance decks. This is also an area which supports the hydraulic lifting system. It is also an area where steel is assembled.

Pace

Present slip form pavements use concrete of high strength which is achieves this strength in approximately 12 hours.  Traditional slip forming concrete required 5-14 days to achieve this strength. It is necessary for construction companies to use a low slump concrete while the structure is being moved horizontally. This can help the slab or pavement to retain its shape with the advance of the paving machine (Dr. Mohammed Ghonim, SLIP-FORM CONSTRUCTION, 2015).

Customization

Slipforming methods known as tapered slip-forming is used for conical chimneys, cooling towers, piers and other tall concrete structures. These structures involve changing thickness in walls, diameters and shapes. While the tapered slip-forming process is similar to the standard slip-forming, it requires greater attention.  Slipforming in general and especially tapered one, requires lesser number of workers but more experienced and skilled ones. Additionally, contractor experience and expertise can deliver a magnanimous and durable structure effectively.

Equipment

Slipforming technique was originally used for building silos and grain elevators. Hydraulic jacks and their use for elevating is the structure is of paramount importance to the construction. With the use of these jacks, installing steel reinforcement and pouring concrete become much easier and faster. Such equipment can be bought in a wide variety for elevating different kinds of loads.
