Abstract: The disclosure relates to portable staircases having a staircase assembly including an outer staircase and an inner staircase that can move in a telescoping relationship with respect to the outer staircase. Portable staircases of the disclosure are particularly useful for accessing an oil drilling rig as they are independently supported with respect to the drilling rig, thus providing numerous safety improvements and advantages. Methods of using the portable staircases of the disclosure are also disclosed.

Abstract: The present invention relates to a method for controlling an articulated turntable ladder (12) of a rescue vehicle (10) wherein the ladder (12) comprises a plurality of telescopically extendable ladder parts (14) by including a tip ladder part (18) pivotable around a horizontal first pivot axis (28) by means of a first pivoting drive. The ladder further comprises a cage (22) connected to the free end of the tip ladder part (18) to be pivoted around a second pivot axis (30) by means of a second pivoting drive. The ladder (12) is pivotably mounted to a base part (16) on top of the vehicle (10) by means of a third pivoting drive to be lifted or lowered around a third pivot axis (32). The method provides for the step of controlling the first pivoting drive such that the absolute inclination angle (α) of the tip ladder part (18) is maintained constant during a lifting or lowering movement of the ladder (12) around the third pivot axis (32).

Abstract: Systems are provided for storing and retrieving objects such as ladders. The systems can include a carriage having a table that rotates, and a trolley mounted on the carriage for holding the object and moving the object linearly in relation to the carriage, so that the object can be stowed in locations such as on the roof of a fire engine or other emergency vehicle, or the roof of a stationary structure. The systems include features for locking the table and the trolley to increase the safety and efficiency of the loading and unloading processes.
