A rope fastening arrangement of a hoisting device, which comprises a rope drum, a fastening device having a chamber which defines the vertical boundary dimensions, the horizontal boundary dimensions, and depth direction boundary dimensions of the fastening device, a hoisting rope and a hoisting member which by means of the hoisting rope ascends and descends supported by the fastening device and rope drum. Said rope fastening arrangement further comprises that the hoisting rope () is locked to the fastening device by wedging, whereby the fastening device guides the first end of the hoisting rope away so that the first end of the hoisting rope does not extend outside the vertical boundary dimensions of the chamber.

Rope fastening arrangement of hoisting device

A trolley of a crane is arranged to move along a main support structure of the crane. The trolley includes a support frame structure; bearing wheels which are fastened to the support frame structure and by means of which the trolley is arranged to move along the main support structure; and a hoisting mechanism that has a rope drum for a hoisting rope, a rope pulley arrangement through which the hoisting rope may be guided from the rope drum to a fixed fastening point on the trolley, and a hoisting member in cooperation with the hoisting rope for hoisting a load. The rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. The rope pulley arrangement is located, in the axial direction of the rope drum, at least partly outside one rope drum end which is on the side of said fastening point. The support frame structure is divided into two separate frame parts, whereby the first frame part supports the rope pulley arrangement and the rope drum end on the side thereof, and whereby the second frame part supports the opposite end of the rope drum. A pivoted joint is arranged between the first frame part and the second frame part, which allows the first and second frame part to move relative to each other around the vertical and horizontal axis and the longitudinal axis of the first and second frame part.

Trolley of a crane

There is provided an apparatus, a monitoring arrangement, a method, a crane and a tool for monitoring a condition of an elongated ferrous object having a longitudinal axis. Two magnetizing circuits including magnetic poles are arranged along the longitudinal axis of the object. A magnetic flux guide connects the poles. The magnetizing circuits are arranged around the object at opposite sides along the longitudinal axis, wherein the magnetizing circuits are hinged together to be movable between a closed position, where the object is enclosed between the poles of the magnetizing circuits and an open position, where monitored object is removable from the apparatus. The apparatus includes an enforcing element operatively connected to the magnetizing circuits such that, in the closed position, the magnetizing circuits are pressed towards each other; and the operative connection between the enforcing element and the magnetizing circuits is caused to disconnect on the basis of detecting a faulty portion of the longitudinal ferrous object by a force received from a faulty portion of the longitudinal ferrous object.

Monitoring condition of elongated ferrous object having a longitudinal axis

The invention relates to a trolley () of an overhead crane, supported to be movable between two main girders (), whereby there is a service platform () on the side of the trolley, the service platform being turnable or slidable in the upward direction and/or towards the trolley.
