ABSTRACT:
An anti-tip arrangement for a mobile system, such as a mobile storage system, in which a movable member is mounted to a rail arrangement. The anti-tip arrangement includes an anti-tip member which is pivotably mounted to the movable member for movement between an operative position and an inoperative position. The anti-tip member has a hook section that is engageable with an engagement surface of the rail arrangement, for preventing tipping of the movable member relative to the rail arrangement. The anti-tip member further includes a retainer section and a tab section that extend in opposite directions from the pivot axis about which the anti-tip member is pivotable. The tab section extends laterally from the pivot axis, and is engageable by a user to enable the user to pivot the anti-tip member to the operative position. The retainer section is offset from the tab section, and is adapted to receive a releasable retainer member, such as a retainer pin, which maintains the anti-tip member in the operative position. The offset of the tab section from the retainer section facilitates the ability of the user to manipulate the anti-tip member for movement to the operative position while engaging the retainer pin with the retainer section.
