Chain speeds of from 50 ft. to 80 ft. per min. are common, with capacities as highas 1,200 boxes per hour. For elevating bales of jute, wool,or cotton, or for heavy packing cases, heavier constructionis necessary, with low chain speeds of from 30 ft. to 40 min. to provide for the greater strain. Wood Shooks—Boxes The extensive use of the push-bar elevator for handlingbox shooks, boxes and similar light packages has beenlargely due to the simplicity of installation of the lightequipment necessary for this work. The ease of spanningroadways, streets, or yards—with a minimum of frame-work^—^makes it feasible to use this elevator in places where. Connecting Operations in Different Buildings the heavier apron types would be impractical, or belt ele-vators, because of the greater protection necessary, wouldbe much more Working in combination withgravity or power conveyors, the push-bar elevator is wide-ly used in furniture manufacturing, box-making, and simi-lar wood-working plants, to connect in continuous se-quence operations in different departments or buildings. The simplest method of spanning between supports is toso design the side trusses that the elevator frame will beself-supporting. Knee braces from the supports at eachend stiffen the truss and increase the possible span, or,where the span is too long for this, sway rods are oftenrun from above the end supports. For the longer spans,however, it is customary to build light trusses independe
