A bucket-conveyor component with a low-weight design
This company’s central chains for mechanical conveying in bucket elevators are now available in a new variant that has a lower-weight design (photo). An advantage of central chains over round-link chains is that they can be run at higher speeds. The central chains provide a robust means of traction for vertical conveying of powdery, granular, lumpy and high-temperature materials. The central chains are suitable for a range of industries and applications, including gravel, limestone, rock salt and cement, according to the company. The new generation of central chains is now significantly lighter. It works with less deadload and with better performance, the company says. The weight reduction of the central chains was a result of a worldwide survey done with the company’s customers and sales partners. In addition to installing them in new systems, they can also be retrofitted on existing bucket elevators that have round link chains or belts. This company’s central chains are available in two variants, with a separate or an integrated mounting bracket. The central chain with a separate fixing bracket is in size RU 100, which has a breaking force of 1,000 kN, a weight of 45.2 kg/m and is suitable for bucket widths between 400 and 800 mm. Three chain sizes for the central chain are available with an integrated mounting bracket: RU 40, RU 55 and RU 70. — RUD Ketten Rieger & Dietz GmbH u. Co. KG, Aalen, Germany
