  This jacking device has more than one extension, allowing for multiple height adjustments. It has an inner tube with nuts, an outer tube with holes, a screw, top and bottom plates, and a nut welded to the inner tube. It is ideal for projects requiring different height levels, such as underpinning and repairing walls. It is versatile and can be used in many construction projects.

• Pre-Fabricated Shore Jack

  This screw jack is built off-site and then installed on-site. Its construction is precise, so it provides consistent quality. It saves time during construction because installation is easy. It is used when there is a need for quick shoring solutions, such as in emergency structural repairs. It is also cost-effective for large-scale projects.

• Adjustable Shore Jack

  This shoring jack is designed for height adjustment. It has a screw mechanism that allows the user to increase or decrease the height. It is ideal for temporary support of beams, formwork, and other structural elements during construction.

Function and features of adjustable height shoring screw jack

The adjustable height shoring screw jack has different features and functions, and these include:

• Support beams

  Support beams are an important part of building construction. They help hold the structure and carry the load. Support beams need shoring props, which help them carry the weight during construction. Shoring beams are temporary support beams used to hold other support beams during construction until the construction support beams are cured and ready to hold on their own. Shoring beams come in different sizes, and the adjustable shoring props help accommodate these different sizes.

• Heavy-duty construction

  The shoring screw jack is made for heavy-duty construction. It is made with high-quality materials that can withstand harsh conditions. It is also designed to carry loads of up to 54KN.

• Height adjustability

  The adjustable height shoring jack is height adjustable. It can be adjusted to different heights to provide temporary support to beams of different heights. These shoring props can be adjusted to a height of 1.1m to 3.5m, or 1.5m to 4.0m, depending on the type. With this support, construction beams can be safely supported as they cure.

• Quick installation

  These shoring props are easy to install and can be done quickly. They are also easy to remove after construction is done or when the support beams are ready to hold on their own. This is because the shoring props are designed to lock in place and can be easily released when the construction is complete.

• Safety features

  These shoring props have safety features that ensure safe construction. They have anti-slip feet that provide stability and safety while the shoring props are supporting the construction beams. The adjustable height shoring jack can support beams of different heights and sizes without slipping. They also have load capacity indicators that show the maximum load capacity to prevent overloading.

Scenarios of adjustable height shoring screw jack

The adjustable height shoring screw jack is a vital component in the construction industry, especially for temporary support. Its application spans across different construction scenarios. Below are some of the common application scenarios:

• Structural Support

  Construction projects frequently use construction jack supports to temporarily support beams, columns, or walls during the construction phase. It helps in load distribution during the building process, ensuring safety and stability of the building structure.

• Height Adjustments

  This type of jack is extensively used in construction sites where height adjustments are frequently made. These include shoring foundations, supporting formwork, and underpinning walls. Its screw mechanism allows seamless height modifications to accommodate different building heights and uneven ground.

• Temporary Propping

  These jacks provide temporary propping of structural elements during renovations, repairs or installations. This allows continued work on structural elements without compromising safety. As a result, it reduces the risk of collapses or settling during such construction processes.

• Load Bearing Walls

  These jacks are essential in supporting load-bearing walls during structural modifications or replacements. Typically, they are placed on either side of the wall to absorb and distribute the load to the ground, ensuring structural integrity during the wall replacement process.

• Formwork Support

  Formwork is used to mold concrete into desired shapes and structures. Adjustable shoring screw jacks are used to support formwork for beams, slabs, and columns. They provide a stable and adjustable platform to support the weight of wet concrete until it cures.

• Underpinning

  Underpinning involves strengthening or deepening existing foundations. Screw jack construction is used to support existing structures while excavation and foundation work are carried out. This ensures safety and prevents shifting or settling of the structure during underpinning.

• Ground Support

  In underground construction, such as tunnels or basement excavations, shoring screw jacks provide ground support to prevent cave-ins. They are inserted into the ground at angles to create a triangulated support system that withstands lateral pressures from soil and rock.

How to choose adjustable height shoring screw jack

• Load Capacity

  Determine the maximum load that will be supported. This depends on the type of construction, beam size, and span. Higher loads require more robust shore jacks.

• Height Range

  Consider the height adjustments needed for your project. Ensure the screw jack can reach the required heights. Different screw jacks have various height adjustment ranges.

• Material and Durability

  Look for durable materials that can withstand repeated use. Steel jacks are long-lasting and suitable for most projects. Galvanized steel options resist corrosion, especially for outdoor or humid conditions. Aluminum jacks are lighter and easier to handle but may have lower load capacities.

• Stability and Safety Features

  Choose jacks with a solid base plate for better ground contact and weight distribution. This prevents sinking or tipping. Check for safety features like locking mechanisms to secure adjustments and prevent accidental sliding. Non-slip surfaces on the screw thread enhance safety.

• Ease of Use

  Consider how easy the jacks are to operate. Look for smooth adjustment threads that make raising and lowering simple. Quick-release mechanisms speed up the process. Lightweight and well-balanced jacks are easier to position and adjust on-site. Carrying heavy loads becomes less strenuous.

• Maintenance Requirements

  Choose jacks that require minimal maintenance to save time and costs. Opt for models with corrosion-resistant coatings for longevity. Regularly clean and lubricate the screw threads to ensure smooth operation.

• Cost and Value

  Balance initial costs with quality and durability. Cheaper options may save money upfront but could lack longevity. Consider the rental potential of high-quality jacks, which can offset costs over time. Read reviews and testimonials to assess the brand's reliability and customer support.
