Patent abstract
An extended safety cage provides access to a plurality of hatches on the top of a mobile container. The cage is rotatably attached to the end of a gangway, which extends from and is rotatably attached to a platform. The platform carries a pair of braces that extend out in opposite directions and support the cage through spring-loaded lifting arms. The apparatus can include actuators, such as hydraulic or pneumatic actuators, that urge the gangway and cage downward when activated. Secondary braces ensure that the lifting arms and safety cage move in unison.
