Specifying a brake which will operate reliably and efficiently, with minimal maintenance intervention, is a challenge that must balance initial expenditure with the through-life costs. The main factors to consider include more than simply the duty (whether the brake is being used for dynamic stopping, static holding or continuous tensioning), but also what sort of environment the brake will be located in.
Heavy duty braking system designs are as diverse as the different industries in which they are employed. From marine and mining to metal working and paper processing, systems are required to perform static, dynamic and emergency braking with precise controlled force. Quality is of the upmost importance in these products as the cost of a short service life can often be extremely high for the end-user.
A large steel recoiler OEM needed a custom gearbox for use on a new steel pickling line recoiler. The drive is direct coupled to a 125 HP electric motor which winds up a 52" wide, 60,000 lb. steel coil after it passes through the pickling treatment line.
