Dock Sentinel™ Loading Dock Safety Gates

WHAT YOU SHOULD KNOW ABOUT NOVA’S DOCK SENTINEL™ SAFETY GATES

NOVA Dock Sentinel™ Safety Gates are durable, reliable and safe. They are easy to install and operate and provide an effective barrier for personnel and equipment working near open dock doors, truck loading docks or other dangerous areas.

Overhead door damage is often the highest maintenance expense at busy loading docks. The Dock Sentinel™ Safety Gates are placed in front of the dock door to protect the dock door and door tracks from collisions with forklifts and to prevent pedestrians from walking off the dock. The Dock Sentinel™ Safety Gate should extend the width of the door. When the gate is open, the full width of the door is available for pass-through.

FEATURES AND BENEFITS

Lower barrier construction of ¼-inch wall ASTM A500 structural steel tubing
Powder coated in highly visible safety yellow paint
Extremely low maintenance
1 year warranty against manufacturer’s defects
Flex hinge design dissipates impact energy to withstand multiple impacts from pallets or pallet jacks
Economical—priced lower than other gates providing similar or lesser protection
Easy installation—simply anchors to floor
When open, gate provides a full door width pass-thru clearance
For added safety, barriers secure in the upward position with self-engaging latches

STRUCTURAL

The uprights are constructed from 1/4 inch thick A-36 steel, formed and welded into a custom 6 1/2 inch web × 10 3/4 inch flanged channel for maximum door track protection. The channels are welded to 3∕8 inch thick A-36 steel base plates and anchored to the floor with a total of (8) 5∕8 -11 × 4 1/2 inch long anchor bolts, included. Both arms of lower barrier are made from A-500 Grade B rectangular steel tubing, 5 × 2 × 1/4 inches thick, and joined in the middle when the gate is closed with a 14-inch long saddle. The saddle is a formed and welded channel made with gussets 1/4 inch thick A-36 steel. In addition to the saddle, there are also interlocking glad hands made from 1/4 inch thick A-36 steel to provide additional impact resistance. The hinges for the lower barrier are contained within an energy absorbing polymer for maximum impact protection with minimal damage to the barriers, material handling equipment and product. An upper barrier constructed from A-500 Grade B square steel tubing, 1 1/2 × 3∕16 inches thick, is provided for status at a glance visual indication when the gate is closed and to keep pedestrians from tripping over the lower barrier. Both sides of the gate are independently powered with a total of (4) gas springs resulting in minimal manual lifting force to raise or lower the gate and latches are provided on each side to positively retain the gate in the open condition. The entire gate is powder coated safety yellow for optimal visibility and durability.

OPERATION

The NOVA Dock Sentinel Safety Gate is a manually operated gate style barrier. When dock use is required, the NOVA Dock Safety Gate is opened by simply lifting the gate into an upright position until latched with very little effort. When dock use is finished, each side of the gate is unlatched and lowered back to the closed position.
