With capacities up to 100,000 lbs; handed left/right with vertical adjustment. For use on lead filled radiation doors, vault doors and heavy architectural gates. Also any door application where the hinges will be subjected to severe loads from a blast pressure, seismic event, or high wind velocities.

Series W hinges will function at the rated capacities providing the following specifications are met:

1. The hinge pin centerlines are installed collinear with each other in 2 vertical planes, and with no misalignment.

2. A minimum of 2 hinges (1 pair) are used per door.

3. Door weight or thrust load shall never exceed the thrust capacity of one hinge. In addition, the radial capacity shall not been exceeded.

4. When approaching the thrust and/or radial capacity in high frequency applications, it may be necessary to go up in hinge size in order to obtain the maximum safety factors for load-life on the roller bearings. Please consult the Engineering Department.

5. Compliance with bolting specification.

6. Minimum Thread engagement into reinforcing member shall be equal to bolt diameter.

7. For weld on applications, the minimum fillet weld size shall be as specified for the model number, and be full length on the top, bottom, and vertical edges of the mounting surface of each hinge leaf. There shall be no welding on the backside, adjacent to the hinge barrel. Assure the weld interpass temperature at the hinge barrel does not exceed 225 deg. F.

8. For high frequency applications, adequate load distribution between hinges is recommended to obtain the highest margin of safety with respect to load-life on the roller bearings. This can be accomplished using a torque wrench to equalize the load on the set screw of each hinge. The closer the torque value between each set screw, the closer the load distribution between hinges. In order to perform this task on very heavy doors, it may be necessary to temporarily lift some of the weight off the hinges.

8. Maximum (+) adjustment is 1/8" over nominal. During installation, we recommend pre-loading the hinges to remove any clearances that may develop from a tolerance "stack-up".
