Abstract: A vertical lift gate assembly includes a pair of elongate tubular members vertically erected and spaced apart from one another to accommodate a gate member therebetween, a pair of rail members securely fastened to the tubular members and adapted to receive and guide bearings which are attached to the sides of the gate member, and a pair of flexible lines connected to the gate member and carried by a pair of pulleys mounted to near the tops of the elongate tubular members. The gate member can be raised and lowered either manually which includes a counterweight member attached to the flexible lines and disposed in one of the tubular members; or pneumatically which includes a pneumatic cylinder which is the counterweight member and which receives compressed air from a compressed air source; or electrically which includes a speed reduced motor having a pulley attached to the shaft of the motor and connected to the flexible lines of which are either taken up or let out by the pulley on the motor. The gate member can be raised pass the pulleys on the tubular member all the way to the ceiling in a building structure.
