Fault Analysis and Maintenance Tips for Safe Deposit Boxes

Vault Door Manufacturer: Common Issues in Vault Doors and Simple Repair Methods: It's inevitable to encounter some minor issues while using vault doors normally. Below is an analysis of several common problems and their solutions for your reference:

Hinge creak

It could be due to moisture in the air or dust entering the hinge hinge box, causing the hinge and pin to rub and produce noise. The hinge screws are not properly adjusted, and the hinge pins are not aligned on the same axis. The hinge fixing screws are not tightened enough, and during use, the door, under the influence of gravity, causes the hinges to shift off-axis.

Approach to Handling:

Adjust the hinge screws to align the hinge pins on the same axis (e.g., by slightly loosening the two screws on the middle hinge of a door frame). Inject a liquid lubricant or butter into the hinge pins. Do not use mineral oil or vegetable oil (such as lard or soybean oil).

2. The outer lock cylinder is stuck.

Reason for Occurrence:

The lock cylinder can be intentionally damaged without leaving痕迹 by external force, causing the internal pins to misalign, rendering the cylinder inoperable. Injecting glue and foreign objects into the cylinder by those with sinister intentions can also prevent the cylinder from functioning. Moreover, using technical tools by criminals to manipulate the locking plate can trigger an automatic lock-up, further rendering the cylinder inoperable.

Solution:

Clean the debris and, after adding pencil powder, the lock still cannot be opened due to deliberate damage. Therefore, we recommend users to replace the lock with a new one.

3. The doorframe and door are producing noise due to friction and paint surface wear.

Reason for Origin:

Foreign objects at the hinge edge can cause the door to be slammed shut, leading to external force impacts and compressions on the hinge, resulting in deformation of the door face hinge and frictional noise between the door and frame, as well as paint wear. Excessive force when opening the door can also lead to external force impacts and compressions on the hinge, potentially causing the door face or frame to shift, resulting in frictional noise and paint wear between the door and frame. Overly tight door gaps and uneven gaps between the door face and frame, or misalignment of the edges, can also cause frictional noise and paint wear between the door and frame.

Approach to Resolution:

Tighten the shrinkage screws on both sides of the door frame to pull the door frame apart. Place a long wooden strip, 1-3 cm thick, at the friction point, close the door face with gentle pressure, and the friction can be eliminated. Adjust the door hinge screws with a wrench to position the door and frame gaps correctly. Apply butter to the worn paint surface to fade the wear. Alternatively, spray a self-drying paint with the same sheen. These issues can be avoided by properly adjusting during the installation of the vault door and following the installation requirements.
