A warehouse system employs a crane guided for movement along an aisle with storage racks on opposite sides thereof and mounting a carriage for vertical reciprocation thereon. An extractor supported on the carriage has a pair of narrow extensible arms which engage the undersides of lips formed on opposite sides of a tote pan. The extensible arms each include three rails nested in one-above-the-other relation with the intermediate rail having vertical load bearing rollers engaging the upper and lower rails. A harmonic drive causes extension and retraction of the extractor arms through a chain and pulley arrangement. The tote pans are nestable and have ribbed bottoms cooperatively engaging cantilevered brackets on the storage racks whereby the pans are releasably detained in their stored position in the warehouse.

Tote pan and warehouse rack structure therefor

A sling belt conveyor has a pair of individually tensioned cables (209, 224) with transverse slings (51) pivotally connected to the cables (209, 224) which support a low tension conveyor belt (61) without being connected thereto. The belt (61) extends beyond the path of the support cables (209, 224) and is tensioned independently of the latter.

Sling belt bulk material conveyor
