coupled pulleys

...The hoist is delivered coupled with a trolley to form a monoblock unit. This solution is recommended when it is necessary to reduce the lost height or when it is desirable for the hoist not to be easily detached from the trolley. GENERAL DESIGN - Flanges made of oversized, non-deformable steel sheet. - Cast iron rollers mounted on ball bearings. Removable axles, profiled rims for operation on all...

...Rimor provides ventilation systems without transmissions using belts and pulleys, but directly coupled thanks to innovative and reliable cooling solutions for boxes and shafts (air or water) and the selection of the most suitable materials.

... a drive and tensioning drum, are used for conveyors. To maintain constant belt tension, tensioning mechanisms (screw, gravity - central or end) are employed. The tensioned belt is frictionally coupled with the drive drum, which, while rotating, winds the belt over sets of upper and lower pulleys and guiding drums. The belt picks up material from the feed hopper and transports it to the unloading point, which can be done: - with a fixed, one or two-sided plow chute, - with a dumping cart, - from the drive drum.
