CLASSIC PULLEYS AND BARE PULLEYS
ALTEMA manufactures pulleys for silos and bucket elevators for the port, food processing and agricultural sectors.
Cage pulley
A cage pulley is a pulley manufactured with bars welded to the side plates instead of the tube as on a standard pulley.
LARGE-DIAMETER PULLEYS
ALTEMA manufactures pulleys with diameters of up to 1,300 mm for installations requiring high-speed conveying.
Laggings on industrial pulleys
ALTEMA can equip any elevator pulley with any type of lagging. Each application requires its own type of lagging. ALTEMA’s teams can help you define the type and process that will enable the industrial pulley to perform its function in the best possible way. For applications in the food industry, these rubber coatings are available in appropriate colors according to their specification: white, blue, pink, etc. For transporting food products, silicone rubber is FDA-compliant and 100% approved for this use.
CONNECTING SYSTEMS for elevator pulleys
ALTEMA offers a variety of connections between the shaft and the flanges: removable vecobloc hub or shrink disc, UCFC flange bearing or welded connection to the flange.
CLAMPING RINGS
The shrink disc’s operating principle is based on the radial deformation of the frustoconical parts that form its head. The torque applied to the screw causes an axial movement of these parts, which, due to their conicity, come into contact with each other and generate a pressure force. The advantages of shrink discs are that they eliminate gap between the drum and shaft, and distribute the drum load evenly over the entire shaft diameter.
VECOBLOC UNIVERSAL HUBS
VECOBLOC removable hubs, also known as TAPERLOCK hubs, are the most practical system for securing the drum to its shaft without the need for special tools. ALTEMA offers a wide range of removable hubs to meet all requirements. This solution offers users an alternative to shrink discs when they wish to retain a keyed connection.
