A front pin arrangement for automatic securement of a container to a container chassis is provided. The front pin latching arrangement includes first and second latching systems disposed proximate two corners of a container chassis, wherein each of the first and second latching systems automatically secure the container to the container chassis. The front pin latching arrangement also includes an interlock assembly operably coupled to the first and second latching systems. The interlock assembly is configured to provide a fail-safe operation such that the first and second latching systems maintain securement of the container to the container chassis.

A latching system for automatic securement of a container to a container chassis is provided. The latching system includes an actuation device that extends through a surface of the container chassis, a linkage mechanism disposed below the surface, and a latch coupled to a pivot. The latch is positioned above the surface of the container chassis. Placement of the container on the container chassis actuates the actuation device causing the linkage mechanism to move the latch such that the latch automatically secures the container to the container chassis.

A lifting system for a vertically-elevating cab, the lifting system includes a frame assembly having a first and a second support column, first and a second lift screws which are attached to the, respective, first and second support columns, a cab-lifting beam that has a first and a second end attached to the, respective, first and second lift screws. A vertically-elevating cab is mounted on the cab-lifting beam in such a manner that a center of gravity of the cab is not aligned with a center of the cab-lifting beam. A plurality of rollers are located on each end of the lifting beam. Each one of the plurality of rollers is in contact with a guide bar on each of the respective first and second support columns, and a first and a second power system is connected to the, respective, first and second lift screw.

The system and method for detecting and warning of the proximity of a hazard. In one embodiment this may be achieved by receiving a signal from a RFID tag, determining that the RFID tag is associated with a safety article, and activating a warning device. In another embodiment, a system may be provided that includes a monitoring antenna that receives data transmitted from a RFID tag coupled to a safety article and a processor that transmits a signal to a warning device if the safety article is in proximity to a hazard.

An inventory storage and retrieval system and method are provided for a shipping or storage facility. In an embodiment, the system includes: (a) a mobile computer and radio on a load-handing vehicle; (b) sensors on the vehicle to determine the ground location and orientation of the vehicle; (c) encoders that determine the position of a lifting mechanism relative to a chassis of the vehicle; and (d) a base computer and radio that communicates with the vehicle. The system maintains an inventory database of items and their respective storage locations in three dimensions as a result of the loading activity of the vehicle. The data can be used to guide the vehicle for ground movement generally to a storage location, appropriately orient the vehicle, and then to move the lifting mechanism of the vehicle to deposit or retrieve the item at a particular storage location.
摘要:
A control system and method for obtaining power on demand from a diesel engine in order to operate vehicle functions and accessories. The method comprised of: (1) determining a flow rate necessary to operate each of a plurality of function hydraulic pumps and an vehicle drive pump associated with the engine; (2) comparing the flow rates of the various hydraulic pumps to determine the greatest flow rate; (3) establishing an engine speed necessary to deliver the greatest flow rate; (4) comparing the engine speed necessary to deliver the greatest flow rate with a current engine speed; and (5) adjusting the current engine speed to provide the greatest flow rate required.

In an embodiment, a crane including a hoisting (i.e., load-lifting) mechanism is provided with a variable-speed load-dependent control system and method for operating functions of the crane. An exemplary control system includes an actuator subsystem for performing at least one function of the crane, a sensor for detecting the magnitude of the load lifted by the hoisting mechanism and a controller that communicates with the sensor, wherein, relative to a load signal from the sensor, the controller transmits a speed signal to vary an operating speed of at least one actuator of the actuator subsystem.
摘要:
A gantry crane has first and second side support frames spaced by a pair of trolley beams. A load lifting mechanism is connected to the trolley beams and includes a lift frame for engaging a load to be lifted. An operator cab is mounted on the first side support frame and is vertically moveable between a lowermost position and an uppermost position in an operational plane defined by the first side support frame. A cab lift cable has a length and a first end fixed to the operator cab and a second end fixed to the side support frame. A hydraulic cylinder urges the cable between its fixed first and second ends in a direction transverse to a portion of its length. In another embodiment of the invention, an operator cab is adapted to be horizontally moveable. The elevating operator cab of the present invention can be configured to move horizontally. The elevating operator cab is lifted by a carriage beam vertically moveable along vertical legs of the first side support frame. The operator cab is moveable horizontally along the carriage beam.
