Freight Doors
Freight doors are the vertical bi-parting type with the top half going
up and the bottom half going down. Each half counter-balances the
other. These doors are designed to operate on guides which provide
a very smooth and easy to operate door system. With the door fully
open, the
bottom door serves as a load supporting sill that allows loads to be
moved in and out of the car. The door width is normally the full
width of the car interior. With the unique guide operation, the
manually operated doors move very easily and smoothly. Power
operated landing doors and car gates are also available with the same
guide operation. Labeled interlocks are provided that comply with
every ambient conditions, including corrosive and explosive areas.
Horizontal Slide Doors
These are not recommended for industrial areas. This type of door is used on public use elevators for passenger use only. The upper and bottom sills of the door are much too fragile to withstand the usual industrial use requirements, especially in dusty, corrosive or explosive areas.
