Aspects of unbinding apparatus, methods, and systems are disclosed. One aspect disclosed herein is an apparatus for unbinding a stacked load of logs. For example, the apparatus may comprise: a plurality of support arms movable toward a plurality of side surfaces of the stacked load, each support arm of the plurality of support arms comprising a guide surface and being: adjustable to abut against one or more side surfaces of the plurality of side surfaces; and independently movable relative to the plurality of support arms in one or more directions responsive to a physical shape of the one or more side surfaces to establish a formfitting abutment between the plurality of support arms and the plurality of side surfaces. In this example, once the formfitting abutment is established, the guide surfaces of the plurality of support arms may be positioned and operative to guide a log released from the stacked load along an escape path over and away from an unbinding area adjacent the stacked load. Aspects of related methods and systems also are disclosed herein.

The invention discloses a multi-bar linkage mechanism based conveyor, comprising a gantry system, a multi-bar linkage mechanism based conveyor boom, a boom support, a two-drum winch, a roller unit and an automatic control system. The gantry system, the two-drum winch and the boom support are mounted on a deck of a hull. The conveyor boom is formed of multi-bar linkage mechanisms, the movement of which can be changed. Rollers are mounted on the conveyor boom. The rear segment of the conveyor boom is articulated with the boom support. The two-drum winch is connected to the multi-bar linkage mechanism based conveyor boom via a steel wire rope and by a set of gantry pulleys. A hydraulic device and a control device are arranged between adjacent multi-bar linkage mechanisms. A tension sensor is arranged at an end of the steel wire rope. The whole conveyor is controlled by the automatic control system.

The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.

Railcar ramp systems and related methods are disclosed. An example railcar ramp system includes a carriage slidably coupled to a platform via a track guide. A ramp mover assembly is pivotally coupled to the carriage. The ramp mover assembly positionable between a stored position and an active position. In the active position, the ramp mover to enable movement of the carriage in a lateral direction along the track guide.

A stand-alone, all-in-one refrigerator box and, more particularly, to a refrigerator box that provides a built-in ramp that is moveable between a stowaway position and an angled position in connection with the refrigerator box for loading and unloading the refrigerator box without having to disengage the ramp while the refrigerator door is being opened and closed.
