Hydraulic Door Closer: Waterson's Compatibility Breakthrough

Recently, Waterson addressed a special challenge when a client wanted our heavy-duty 4.5″ hydraulic door closers with Wilson aluminum jambs. The main issue stemmed from the larger barrel size of the old closers, which did not align well with the jambs’ flush casing. This resulted in the hinge leaves not fitting properly, complicating the installation and affecting door functionality.

Solution Implemented

To solve the specific installation challenges, Waterson responded with a customized hydraulic door closers, specifically designed with a 4.5” x 5” dimension. This customization ensured compatibility with the aluminum jambs, resolving the initial issue where the flush casing prevented the door closer leaves from fitting properly. The door closer adjustments made to the closer leaf allowed it to adapt to the jamb structure fully, ensuring a seamless installation.

Q: How often should hydraulic fluid be changed?

Experts recommend changing the hydraulic fluid every 1,000 hours for most skid steer loaders. Besides, if the hydraulic fluid appears milky, dark, or has an abnormal color instead of a clear amber color, take immediate action to avoid severe damage to your hydraulic system.
