A tension setting system for a remote setting of a tension in a transfer cable ensuring a displacement of a transfer carriage along a jib of a crane, including a winch equipped with a motor cooperating with the cable so as to ensure a displacement of the carriage, a pilot unit connected to the motor to pilot a displacement of the carriage, and a setting mechanical device mounted on the carriage and adapted to be actuated by the action of a displacement of the carriage. The setting mechanical device is coupled to the cable and configurable between a working configuration in which the mechanical device stands still irrespective of the displacement of the carriage and results in a holding of the tension in the cable, and a detent configuration in which, by the action of a displacement of the carriage piloted by the pilot unit according to a first sequence of reciprocating displacement, the mechanical device results in a release of the tension in the cable.

A continuous container crane device may include a first track having a continuous shape and a second track having a continuous shape. Preferably, the first track may be substantially parallel to the second track. One or more trolleys may be movably coupled to the first track and to the second track so that the trolleys are configured to move in a continuous movement path (starts and finishes at the same place) defined by the first and second track. Each trolley may include a lifting mechanism that may be coupled to a container spreader which may be removably coupled to shipping containers for the transport of shipping containers to and from trucks with a chassis trailer, all types of intermodal railroad flat cars, ships and other water traveling vessels, container storage lots, etc.

An overhead rail system includes a hollow tube having a channel running longitudinally along a bottom surface of the overhead rail. A stopper for use in the overhead rail, includes a base having a thickness less than a width of the channel of the overhead rail, a base length, a base width, and first and second countersunk threaded holes. The base further includes a pair of wings having a length greater than a width. The wings are rotatably attached to ends of the base and are rotatable approximately 90 degrees between a first position and a second position. Bolts may attach a stopper portion including a stopper base, and bumper base, and a bumper. The bolts further prevent rotation of the wings, thus securing the stopper in the overhead rail.

An overhead hoist transfer (OHT) apparatus and a differential overhead trolley thereof are provided. The OHT apparatus includes a rail module and a differential overhead trolley. The rail module includes a main rail and a first rail, and defines a turning path extending from the main rail to the first rail. The differential overhead trolley is movably disposed on the rail module, and includes a walking mechanism and a carrying body that is hung on the rail module by being connected to the walking mechanism. The walking mechanism includes two differential wheels and a driving unit that is connected to the two differential wheels. When the differential overhead trolley is moved along the turning path, the driving unit is configured to drive the two differential wheels to move along the first rail by different rolling velocities.

An overhead hoist transfer (OHT) apparatus, a guiding device of the OHT apparatus, and a direction maintaining module of the OHT apparatus are provided. The direction maintaining module includes a main channel, a first retaining channel and a second retaining channel that are spaced apart from the main channel, a switch channel, and a switching mechanism connected to the switch channel. The switch channel is disposed among the main channel, the first channel, and the second channel. The switching mechanism is configured to drive the switch channel to move between a turning position and a straight position. When the switch channel is at the turning position, the switch channel connects the main channel and the first retaining channel. When the switch channel is at the straight position, the switch channel connects the main channel and the second retaining channel.

A cantilever hoist device lifts a load in a spatially limited environment includes a support column having a proximal end and a distal end), wherein the proximal end secures the support column in an upright position. Moreover, the device includes an elongated, stiff, and rigid cantilever arm hingedly mounted at the distal end. Additionally, the device includes a drive unit arranged to displace the load towards or away from the cantilever arm using a lifting medium passing one or more pulleys. The drive unit includes a winding body onto which the lifting medium is rollable to displace the load. The drive unit is mounted at the distal end of the support column.
