Mezzanine Safeti-Gates Obtains Second Patent for Dock-lift Safety Gate

New Patent Provides New Configuration Options for Lift Safety in Loading Docks

Essex, MA - February 11, 2020 - Mezzanine Safeti-Gates, Inc., an innovator in the design and manufacturing of industrial safety gates that provide fall protection for employees in warehouses, distribution centers and manufacturing facilities, today announced it has received US patent number 10,519,014 for its crossing-guard gate operation of the Dock-Lift safety gate. This brings the number of patents awarded to the company to six.

Elevated work platform lifts, aerial scissors platforms and pit-mounted lifts in dock operations can pose risks to employees working on the lifts if safety is not provided. As employees use lifts to move material to and from the trucks and loading dock, the two gates on the Dock-Lift safety gates automatically close and lock into place as the lift elevates, forming a barrier for employees on the lift as they make the transition from the tractor trailer to the loading dock or ground level. The gates stay locked until the lift is lowered and back on the ground. The gates automatically open when the platform is on ground level so material can be transferred on and off the lift.

The newly patented crossing-guard style is designed for safety on lifts in which there is limited space. The gates pivot up and off to the side instead of swinging away, which allows the gates to fit lifts in areas of close proximity to the building or loading dock.

“We are very fortunate to have talented engineers that have the ability to create a new methods to provide safety for our customers,” said Aaron Conway, president of Mezzanine Safeti-Gates, Inc. “This is the second patent that they’ve been awarded on the Dock-Lift safety gate model, and this design will be another way we can provide fall protection on this type of elevating work platform.”
