Wedge and shim for heavy machinery and equipment. In the past, large machinery installed in the industrial and marine sector environments suffered from high levels of vibration and shock. This caused loosening in bolts and shims, and misalignment of motors and other base-mounted equipment. Belzona has a new solution for precise alignment. Belzona shimming and shimming solutions have been developed in response to increasing industry demand for maintaining and installing equipment and structures with: Minimum downtime maximum reliability Low cost Shim and wedge inserts with high load resistance Belzona materials are excellent for molding irregularly shaped shims and shims with high load resistance. The materials can be poured or injected into hard-to-reach areas, have excellent compressive strength and do not shrink after curing. long lasting solution precise alignment great load capacity Minimum downtime.

Load-bearing floor areas, pedestals, and supports suffer damage from impact, vibration, or chemical attack. Epoxy-based repair materials bond strongly to existing concrete, set within hours, and achieve full mechanical hardness shortly thereafter. Their high compressive strength, chemical and abrasion resistance, along with a simple application method, make them ideal for repairing damaged supports and pedestals, as well as anchor bolt setting. But, what is the difference between the coined and the wedge? Shim is the effective filling of a gap. This can be done for a number of reasons: to get a better fit, to change the clearance, to correct a manufacturing defect or slippage. It is very likely that the equipment has been in service for a long time and wear has caused some of its components to change shape or become misaligned. The coined one, however, is a shim app, but with a specific goal. The idea of ​​a wedge is to make the base plate of a machine a monolithic piece along with the foundation. Or put more simply, that there is full contact and load transfer between the machine and its foundations. This reduces the vibration produced and the possibility of it damaging the machine. Why is it necessary to perform a wedge and fit? Large vibrating machines are usually placed on concrete foundations. Without effective shims vibration and shock will begin to loosen and loosen bolts. This will lead to misalignment which can be a major problem in equipment carrying heavy loads. Among the options for coining, there are various grouts, which have their advantages and disadvantages. Iron-filled grouts can corrode and degrade. Additionally, cementitious grouts lack the chemical resistance needed in some environments. Although they have excellent compression properties, their impact resistance is not always sufficient. Currently one of the most popular options, especially when applied in situ, is to use pourable polymeric materials (Belzona). Belzona 7111 Shimming and Shimming Compound. Belzona 7111 is a pourable keying compound. It is designed to withstand the physical and thermal shock expected in aggressive environments and exhibits high compressive, impact and vibration resistance, and excellent creep properties. The material itself is a 100% solids two part epoxy. It also features the ease of application that is generally expected of Belzona materials. Not only is it pourable, it’s also self-leveling, which means it can be poured from one corner of the wedge and flows to all areas on its own. This makes it easier for the applicator, since he does not have to remove the entire kit to install the wedge. Furthermore, the benefit of Belzona 7111 is that it can be applied by both the contractor and the property owner. Likewise, the material has a large number of approvals:

The basic principle of coining and shimming is very simple: it is used to fill a hole. The reasons why there could be a gap can be the following: Wear – Two components rub against each other, resulting in loss of material or general wear that causes keyways or keyways to warp. Chemical or environmental weathering can corrode and loosen concrete, which is a particular problem for pedestals. Manufacturing or design issues. If left untreated, this can lead to misalignment of the machine and poor load transfer. This implies that there will be concentrations of stress where there should not be, which will ultimately lead to failures. Corrosion, either crevice or galvanic, can also occur if there are very small voids where there is not full contact between the substrates. Moisture can enter these gaps and thus accelerates corrosion. The most common repair option is to use a metal shim, from simple washers to high tolerance machined shims. However, the problem is that the latter can be expensive to manufacture and it is also difficult to make them perfect if the exact dimensions and shape are unknown. Another option is to use cementitious repair materials, but if it is a concrete-based repair, the same problems are likely to recur. Whatever it is, the most effective option will always be polymeric materials. What are the benefits of wedge and fit? No hot work necessary without solvents High degree of adhesion chemical resistant Durable, long-life solutions.
