A recent Double Vertical Lift Gate installation by Mann Fence Company
This project required two adjacent 48 foot, vertical lift gates to be installed inside an operating manufacturing facility for secure storage of finished goods.
Maximum overhead gate clearance was a demand. While at the same time, working within the very close confines of the facility.
Personnel, equipment and plant safe working procedures are something that Mann Fence takes very seriously.
The substantial weight of the gate lifting columns requires heavy lift equipment. Unfortunately for this project, the equipment required was also capable of lifting to great heights. Our overhead ceiling clearance was only 24 feet, just inches more than the measurement to the top of the installed columns.
The combination of the massive size of the lifting columns and obstacles within the facility required very close attention to prevent damage or injury.
Mann Fence Company Your best choice for the most demanding designs and installations.
Vertical Lift Gates are specified in cases of high usage, especially when there is insufficient space outside of the gate opening for an overhead or cantilever gate to retract before hitting an obstacle. The heavy construction of the superstructure, combined with a drive chain mechanism, lifts the gate open and pulls the gate closed.
This unique drive mechanism features a counterweight that runs inside both vertical support columns. The counterweight is designed to approximate the weight of the gate, assuring the motor and chain drive mechanism minimize stress and maintenance. By incorporating a continuous loop drive system, which is connected directly to the counterweight inside the support column, the Vertical Lift Gate is assured smooth operation in either direction. The vertical support columns of the gate superstructure are constructed of heavy duty W12x53 structural steel.
The gate frame is fabricated from 6063-T6 aluminum alloy extrusions in one or more sections. The gate is attached to the vertical track by means of four self-aligning, 4-wheeled, sealed lubricant, ball-bearing truck assemblies.
A slide operator is used when there is limited space behind the secured facility, so the gate runs parallel to the fence or wall.
Our Slide Gate Operators range from light to heavy-duty depending on the size of the entrance and quantity of open/close cycles. All the features and benefits are identical so selecting the operator is simple.
