Flexible pin couplings for hoist and travel devices of cranes

The couplings form a part of kinematic chain, which is designed to the torque transmission from electric motor to gear box, eventually to another required mechanisms.

 

The fitting of flexible couplings is suitable in such cases, if it is necessary to adjust e.g. the slight misalignment between the shaft of torque source and gear box or driven mechanism. This is performed by means of flexible elements in connection of both parts of coupling, that on a limited scale also protect vibration and impact transmission further to mechanism.

Gear couplings for crane hoisting device

It can be used as a gear coupling of the lifting mechanism of the crane and the drive mechanisms of the crane alone or trolleys. If required, it may be a gear coupling provided also with the brake disc, which is part of the outer coupling halves and serves for braking mechanism by means of a mechanical shoe brakes.

Advantages of gear couplings

Gear couplings deployment is particularly suitable in treated plants and technonologií because these couplings allow the dismantling of the intermediate shaft on which they are installed, without dismantling the associated mechanisms. Long life and shorten repair times in the event of having to change, bringing considerable savings, for example in metallurgical plants in use for casting cranes, but also everywhere else where it is necessary to maintain the continuity of the production process.
