Rack supported mezzanines may rise to four levels or more. Pick to belt system handles high pick volumes. Standard pallet rack is used as the substructure. This can be very cost effective to gain floor space. The carrying capacity of the floor is determined by the capacity of the uprights and beams. The span in the direction of the beams can be 12'. The framework under is all ready to accept extra levels of storage. In addition, the upright frames can extend thru the floor and again are ready to accept more levels of storage. Stairways and pallet drops can be added as necessary.
Rack-mounted capacitor equipment is primarily large installation used to improve the power factor of an entire electrical network. It improves the voltage stability and reduces network losses. Improving the power factor also means a higher power transmission capability and increased control of the power flow. Capacitors are installed in welded galvanized steel or aluminum racks.
