摘要:
A container retention device comprises a housing and an actuator having a first portion disposed in the housing and a second portion movable between a first position inside the housing to a second position outside the housing. The device further comprises a first link assembly in the housing engageable by the first portion of the actuator and movable in response to movement of the second portion between the first and second positions. Also, a second link assembly is disposed in the housing having a third portion engageable by the first link, a fourth portion, and a fifth portion disposed between the third portion and the fourth portion wherein the third portion and the fourth portion are rotatable about the fifth portion in response to movement of the first link assembly. A locking member is extendable outside the housing in response to movement of the second portion to the first position. A container retention method is also disclosed.

A lock for securing a container includes a lock platform, a coupler including a portion that is disposed above the lock platform, an interaction member associated with the coupler, and a linkage mechanism including an actuation device and an actuation surface. The actuation surface is curved or sloped. In addition, movement of the actuation device causes movement of the interaction member along the actuation surface in a first direction such that the coupler automatically secures the container to the lock.

A chassis stacker having a first and a second vertical storage rack displaced from one another by a distance wide enough to accommodate a trailer chassis, and connected at a top end by a trolley rail support beam. A trolley is positioned on the trolley rail support beam, said trolley having an elevation system capable of raising and lowering a first and a second stabilizing beam that are suspended from the trolley and guided in their vertical motion by low-friction, storage-rack contact members attached at respective first and second ends of the elevating structure, said contact members in contact with an inner surface of the respective first and second vertical storage racks. A first and a second stabilizing-beam trolley is attached to the, respective, first and second stabilizing beams while a spreader containing a chassis-clamping mechanism extends between and attaches to the first and the second stabilizing beam trolley.
摘要:
A sensor system includes a mounting member, an actuator disposed adjacent the mounting member, and a sensor connected to the actuator for sensing movement of an object using a signal. The actuator moves the sensor from a first sensing position to a second sensing position if the sensor is unable to read the signal.

A latching system for automatic securement of a container to a container chassis is provided. The latching system includes an actuation device disposed on an upper surface of the container chassis, a linkage mechanism disposed below the upper surface, and a connector positioned on a further surface elevated above the upper surface. Placement of the container on the container chassis actuates the actuation device causing the linkage mechanism to move the connector and automatically secure the container to the container chassis.
摘要:
A method of transferring a load is disclosed. The method includes the steps of enabling synchronization of first and second hoists and first and second trolleys and choosing a hoist function or a trolley function. The first and second hoists are a first mover and second mover, if the hoist function is selected. The first and second trolleys are the first and second movers, if the trolley function is selected. The method includes the steps of commanding one of the first mover and second mover to be the master and the other to be the slave and actuating a master control associated with the master. The method further includes the step of outputting signals to the first and second actuators such that the master and the slave are moved in a direction indicated by the master control.

A dynamic inventory tracking and transfer system is provided that, when in operation, keeps track of inventory by tracking vehicle positions and inventory transfers. A transceiver on a vehicle detects and transmits a signal to the tracking system whenever a vehicle latches onto inventory and/or releases (i.e., unlatches) inventory. Whenever latch and unlatch signals are detected close in proximity to one another, the system concludes an inventory transfer has been made between the two vehicles. The inventory monitoring takes place in real time, thereby allowing inventory to be tracked from the time it is removed from a ship/train to the time it leaves a sea port, rail terminal or industrial yard.

A method is provided for calibrating past position estimates from a positioning system that provides real-time position estimates of a mobile object. The method first stores the real-time position estimates, which as time goes by become past position estimates and naturally form a first past trajectory depicting the past movement of the mobile object. Subsequently, a calibrated past trajectory is determined, which includes calibrated past position estimates that correspond to the same time instances as the past positions in the first past trajectory. When real-time positions have low qualities, this method calibrates them at a later time by using (higher-quality) real-time positions both before and after them. Errors in the past positions are then corrected based on the calibrated past trajectory. When used with event detectors that indicate inventory transactions, this method can correct position errors associated with inventory events so as to improve the performance of inventory tracking.
摘要:
A method for tracking a shipping container in a freight yard that includes the steps of: (a) assigning a specific temporary storage position to the container; (b) confirming, upon arrival of the container at a temporary storage position, that the position is the assigned specific temporary storage position; (c) recording a container serial number and an identification number for the specific temporary storage position once the container is placed in the specific temporary storage position; and (d) recording a date and a time that the container was placed in the specific temporary storage position.

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.
