Abstract
The invention relates to an apparatus for reducing overload and dampening collision energy, for instance, in connection with a container crane, the apparatus comprising a movable bar (16) to receive a load and a resistance device (18) against the predetermined resistance of which the movable bar are able to move in a dampening situation, and the resistance device comprise at least one friction device (18) arranged to cooperate with the movable bar (16).
Claims11
An apparatus for reducing overload and dampening collision energy acting on lifting ropes of a crane, a support beam being provided for receiving a load from the lifting ropes, the apparatus comprising:
- movable means for receiving a load from the support beam, the movable means including a support bar;
- resistance means against which a predetermined resistance is applied for dampening movement of the support bar, the resistance means includes at least one friction device cooperable with the movable means, the resistance means being attached to the crane, the friction device comprising a body having a channel therein, the channel being provided with a friction surface, the support bar passing through the channel;
- and
- means for generating and adjusting friction force between the channel and the support bar.
