| 20110062733 | SYNCHRONIZATION OF SPREADER TWIST-LOCKS IN TWIN LIFT OPERATIONS - 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. | 03-17-2011 |
| 20090200814 | FLIPPER ARM DRIVE - 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. | 08-13-2009 |
