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.

Latching device and method for automatic securement of a container to a container chassis

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.

Crane trolley and hoist position homing and velocity synchronization

A trolley control system for a gantry crane having a multiple trolley arrangement such as a first and second trolley. The control system including a trolley beam connected to the gantry crane with a first and second drive device connected to the trolley beam. The first drive device is powered by a first drive system while the second drive device can be powered by either the first drive system or the second drive system. A first trolley is connected to the first drive device while a second trolley is connected to the second drive device.
