Caravan support and hoisting system struts - has U=shaped across caravan chassis, housing two threaded spindles in tandem and with slidable, but non-rotatable nuts

摘要

The support strut has one end on a pivoted captive nut moving along a fixed spindle, while the other end has single or double support rolls. A link lever is pivoted between the chassis and a point some way down the length of the strut for stability. The strut provides a strong support while the rolls allow the caravan to be moved more accurately into the parking position, with chocks securing the rolls in the final setting.
