As a service supplier of high-quality components for elevators, we help you to secure the mechanical side of your elevator. An important next step in this process is monitoring to make sure continuity is guaranteed. Considering an elevator is an enclosed system, knowing what is going on inside the elevator is a must. After all, prevention is the better cure. Both preventive and curative measures must be taken to ensure full and safe monitoring. To guarantee this, Muller Beltex offers a total solution with “fail safe” products it has developed and engineered itself along with external components to be able to supply a complete elevator in conformity with the latest ATEX directives.

Muller Beltex monitoring systems oversee the entire production process thus ensuring a sustainable, problem-free bulk processing and optimum reliability. See our product overview of process monitoring systems below.

• Belt misalignment monitoring
• Bearing temperature monitoring
• Speed monitoring
• Junction boxes, controllers, indicators & transmitters
• Level instruments
• Data acquisition & SCADA systems
• Explosion vent panels & flameless vents

Besides our extensive range of process monitoring systems we also offer engineering, technical support and supervision. Involve us at an early stage so we can offer you the right, safe and reliable solution for your specific issue based on our broad experience and know-how.

The demand for safety in and around the elevator is an issue subject to adaptations of the relative applicable directives. Statistics describe the elevator as one of the most hazardous pieces of equipment because of real risk of explosion. 30-40 percent of dust explosions involve elevators. An enclosed system combined with the conveying of flammable bulk material, oxygen and possible ignition sources explain this risk of explosion. Research has shown that this can be prevented and damage can be effectively limited with various preventive and curative process monitoring systems.

To prevent the spread of fire and further limit the risk of explosion one can opt for an antistatic ISO 284 and flame-retardant ISO 340 (= DIN–K-) elevator belt. In addition to our Polysur® types 272 and 278, which are already flame-retardant and own other properties, we’ve extended our range of conventional elevator belts with an extra property: flame-retardant in accordance with ISO 340 and added to our range of Polysur® elevator belts named “Polysur® type 275-K”.

At all times, we approach elevators from an elevator belt perspective. To us, the elevator belt is the key issue. This is the heart of the machine and, when running, the belt is subjected to various loads. And because of that, most vulnerable. Therefore, our range of components for elevators comprises all components that come into contact with the elevator belt because of their influence on the service life. In this respect, drive and return pulleys are very important components. They are constructed to suit the elevator belt and the kind of product that is being processed. From drive pulleys and cage pulleys to wing pulleys: our engineers take care of the entire process, from drawing to implementation to guarantee that the elevator belt runs properly and smoothly on the pulleys. Special attention is paid to the crowning of the drive pulley surface, construction strength, shaft connection and static balancing to realize an optimum service life for your elevator belt along with the best production result.

For elevators taller than 25 metres we advise the use of a pulley lagging on the surface of the drive pulley. Because friction between the elevator belt and the drive pulley is an absolute must for a positive grip. This prevents the elevator belt from slipping and reduces wear. Easy replaceable pulley lagging such as Slide-Lag is welded onto the surface of the drive pulley, or rubber with a diamond profile is bonded to the surface using a cold vulcanisation process. The latter is also available in food-grade quality in the colours white or blue. When a rubber pulley lagging does not suffice, for instance at very high temperatures, we recommend interchangeable pre-shaped steel segments with a sintered nickel alloy: known as Metal-Lag.
