In 48" travel, other platform sizes are available. Listed ship weights are for standard platforms only. When voltage is 230V/1PH/60Hz lift speeds will be reduced by 33%. Note: Where available power supply is 208V/3PH booster transformers are required for 240V/3PH at motor, see options. Roller shades, accordion skirting and electrical tape switches will require a minimum lowered height of 10". Power requirements depend upon frequency and type of operation and require specific selection. 8'0" wide units require shipment via flatbed.
