They don’t leave you out in the cold!

EAS®-torque limiting clutches by mayr® power transmission for low temperatures down to -48°C   Raw materials extraction in Siberia and Mongolia at daytime temperatures of far below zero degrees Celsius presents enormous challenges to machines and all their components. Standard designs quickly reach their limits here. mayr® power transmission has now further developed its EAS®-element clutches so that they are also suitable for use at very low temperatures. Extensive trials confirm the functionality of the clutches at low temperatures of -48°C.   Your breath crackles and freezes; you have the sensation of walking over broken glass as you go over the snow, and truck engines run continuously from October through to April, day and night, otherwise they would freeze up. In Siberia, the cold dominates major parts of everyday life; the temperatures can drop during the nine winter months to -50°C. Here lie not only the coldest inhabited locations of the earth – Siberia, like Mongolia, is one of the regions of the world most rich in raw materials. Machines, which are deployed there for the extraction and preparation of raw materials, such as coal and ores, are subjected to extreme conditions. Cold-resistant constructions are required. “With high-strength, through-hardened components, cold weather embrittlement increases the risk of component breakage; there is hardly any specialist information available for reliable theoretical dimensioning of these components”, explains Helmut Kleinheinz, Sales Manager at mayr® power transmission. “This means that further queries must always be made for applications in low temperature areas. Reliable statements can only be made if the constructions are also tested under the conditions which await them in real application cases”....

Breaking free from the clutches of mediocrity

Brakes and clutches are often the defining element in the operation and productivity of driven machinery. However, they are frequently taken for granted, so here, Mike Hemming, Engineering Manager at Matrix International in Scotland redresses the balance. A single brake or clutch failure on a heavily laden conveyor in a mine or quarry could easily stop all production until it is fixed. A misbehaving brake on a remote wind turbine could reduce grid power for months until it is fixed. A paper mill will grind to a halt if its servo motor brakes are anything less than perfect. Breakdowns on marine equipment are never welcome. And, if an aerial access platform gets stuck in an extended position, someone might miss their tea. Matrix International has been delivering high technology and cost-effective engineered brake and clutch solutions for over 65 years including electromechanical, hydraulic and pneumatic units to industries as diverse as forklift trucks, off-highway vehicles, printers and papermakers, mining, materials handling, marine, wind turbines and renewables, farm equipment, escalators and elevators. Many projects in which we are involved are bespoke and require carefully designed and precision-made solutions. For this reason, the heart and soul of Matrix is a dedicated team of talented design and production engineers, who pride themselves on their problem solving ability, technical knowledge and creative thinking. Our parent company, Altra Industrial Motion, has invested to make sure that we have all the facilities necessary to stay at the forefront of our industry, including a wide range of test rigs with which we can simulate operating conditions under the control of computerised systems with data recording facilities....
