Tensioning systems by Murtfeldt
Ensure regulated machine operations with Murtfeldt tensioning systems.
Chains and belts are pivotal wearing parts in many plants and machines. Because they are constantly in motion, they are subject to especially high stresses and strains. Belts require pre-tensioning and chain links stretch, causing increasingly turbulent movement.
Murtfeldt tensioning systems reliably keep chains and belts at the correct tension and thus increase their lifetime. They have proved their worth around the world over decades of use. Our past experience means that we can provide optimum advice and supply the best possible solution on every occasion.
Wide range of products - extensive warehouse
Thanks to our diverse range of different tensioning systems, we can meet practically any requirement quickly and accurately. If you require a custom solution, our consultancy service will gladly provide free, non-binding advice whenever you need it.
The advantages of our tensioning systems:
Our tensioning systems are free-running and resilient. As a result, they do not function as rigid deflectors when stressed. This avoids excessive contact pressure. Our systems aim to keep the overall force on the slack strand ? resulting from the weight of the chain and the centrifugal force ? under control. The ideal installation position is right behind the drive sprocket in order to keep the length of the slack strand that needs to be tensioned as short as possible.
Tried-and-tested quality:
The stable design of the steel housing makes our tensioning systems resistant to high mechanical loads. Our housings and tensioning systems are galvanized, which provides protection against corrosion. A plastic lacquer makes the surface impact and scratch resistant. In addition, we offer a stainless steel range for particularly high corrosion resistance requirements. All slide profiles are made of Original Material S®.
Installation:
Special holding mechanisms initially hold back the spring action. When these retainers are released following the installation, the tensioning pressure is released in a targeted manner.
Tensioning force regulation:
For all Murtfeldt tensioning systems, you can choose either light or heavy tensioning pressure. Depending on the type, the tensioners have one, two, or three springs. You decide how many springs you want to use. This enables the optimum application of pressure onto a chain or belt running on the profile
Use at extreme temperatures:
If you choose the correct material, you can also use our tensioning systems in otherwise problematic temperature ranges:
Optimum installation position:
Employees from our application technology department are constantly available to make sure that we are able to provide the best product to meet your requirements.
The weight on the return side of the chain that is to be tensioned should not be greater than the force of a spring already 50% released.
The red dot on the SPANN-BOX® means heavy tensioning force.
