Pulley with revolving flange opening for steel cables
Technical sheet
/ Use

Slow pulling or handling and cable tensioning operations, for which the pullies are often repositioned and must be both highly resistant and extremely light, with minimum winding ratios, such as R = 5 or 6.3, since the sheaves have a low turning rate.

Lifting at speeds or frequencies that vary according to winding ratios and ISO/FEM use groups.

Pulling or tensioning operations with overloads of up to 60 % of the maximum vertical static load (WLL) for lifting operations are permissible in situations where no shock occurs when the load does not leave the ground.

Advantages

Pulley with unique advantages :

- lightweight : use of "HR" steel with good anti-aging properties and resistance to cold temperatures,

- does not unhook: the apparatus opens by releasing the locked shaft and turning the plate on the sheave shaft,

- interchangeable hanging parts: alloy hook with pawl or swivel and "HR" shackle or shaft and fixed socket centred for hooking,

- for oblique returns:the "cable guide" sheave groove is designed for 6 x 36-180 kg/mm2 cables,

- does not wear out: the hub of the bronze banded sheave, fitted with a lubricating unit, is mounted on a tempered, case-hardened shaft,

- permanent lubrication: sheave on sealed bearings,

- bichromate finish.
