An arrangement in connection with clamping tools, which comprises a nozzle structure which consists of coaxially arranged nozzle elements and is arranged to form one or more layers which cover a flexible elongated element on the surface of the flexible elongated element, which passes through the innermost nozzle element, in which arrangement at least the head of the nozzle element, which controls the flexible elongated element, is a separate unit which is arranged to be pushed into its position in the direction of the flexible elongated element and provided with gripping means, which grip the innermost nozzle element of the nozzle structure as the unit arrives at the nozzle element. The joint between the separate unit and the nozzle element of the nozzle structure is arranged to be loosened by repulsive force acting on the separate unit in the direction of the flexible elongated element and the separate unit is arranged to exit from the nozzle structure in the direction of the flexible elongated element.

Arrangement in connection with clamping tools

The invention relates to a transmission apparatus in connection with a pulling equipment intended for moving especially a cable or a corresponding product, the transmission apparatus comprising a shaft that is operated by a motor ( ) and that is connected to an output shaft ( ) of the transmission apparatus by means of cog wheels ( ). The output shaft ( ) is connected to means ( ) that are in contact with the cable. The cog wheels ( ) are arranged to form a circle extending from the motor-driven shaft to the output shaft (16) and correspondingly from the output shaft ( ) to the motor-driven shaft. In order to provide clearance-free operation, the cog wheels ( ) are helical gearwheels, and one cog wheel shaft is arranged to be moved in its longitudinal direction when the rotation of the output shaft ( ) is being decelerated.
