Abstract: The present invention relates to an arrangement on a spreader for lifting containers, the arrangement comprising a flipper arm which is supported at the corner of the spreader such that the flipper arm is pivotable between an upraised rest position and a lowered operative position wherein the flipper arm is effective for positioning of the spreader corner relative to the corresponding corner of a container upon connecting the spreader to the container. The arrangement is characterized in that the flipper arm is carried on a rotatable shaft and driven by a motor, and wherein a power transmission is inserted between the motor and the flipper arm, the power transmission being effective for the transfer of torque from the motor to the flipper arm upon energizing the motor, and operative for locking the flipper arm in its pivoted position upon non-energizing the motor.

Abstract: The invention relates to a spreader comprising inner and outer locks connectable to the corner castings of a single container and to two containers connectable in twin relation to the spreader, the outer lock carried in pairs in the ends, respectively, of extendable beams telescopically supported in a main beam, and the inner lock movable in pairs on the main beam exterior, wherein, in each set of associated pairs of inner and outer lock, the pair of inner locks is operable for displacement through a second drive which is separate from a first drive that is operative for displacement of the outer lock through extension/retraction of the extendable beam.

Abstract: An arrangement for a spreader for hoisting containers includes a beam extendable from a retracted position in a housing to an extended position. An additional beam member is received in an inner end of the extendable beam and is arranged to slide axially with respect to the extendable beam, as well as with respect to the housing. An interlocking device is arranged on the extendable beam and on the additional beam member. The interlocking device transfers an extension motion from the extendable beam to the additional beam member. A device arranged on the additional beam member as well as the housing acts to limit the relative axial motion of the additional beam member with respect to the housing. The additional beam member provides an inner end extension of the extendable beam when the additional beam member is extended to engage the device of the housing.

Abstract: The present invention relates briefly to an arrangement for hoisting devices to keep a cable (10) substantially vertically stretched between a derrick or the like and a hoisting device, e.g. a derrick bridle (1), so that the cable will not be able to be depositioned by gusts and other factors. The arrangement includes a set of brackets (12) stretched between and glidably fixed to two opposed hoisting cords (2a, 4a), each bracket (12) being equipped with a ring (13) approximately center, through which ring the cable (10) runs with an increasing inner diameter for each ring (13) from the top downwards. To the cable (10) are fastened a set of elements (14) spaced apart with increasing diameter for each element from the top downwards for each inner diameter of the rings (13) so that each element (14) one by one is restricted to pass a corresponding ring (13) and thereby each hoists one by one a bracket (12) holding the cable (10).
