Selection of brake wheels for mobile X-ray vertical bucky stand

The mobile base of the mobile X-ray bucky stand has 4 wheels, 2 front brake wheels and 2 rear brake wheels. The front brake wheel has a lock opening key, and the rear wheel does not have a lock opening key.
Not long ago, a mobile X-ray bucky stand was sent to Anhui ** Hospital. The hospital raised the issue of replacing the wheels. The hospital wanted to replace the other two wheels with locking wheels, and told the customer that our company designed it like this. There is also a certain reason. If the 4 wheels are all designed as locking wheels, a certain amount of work will be added during the switching process, because the hospital has not actually operated the mobile X-ray vertical bucky stand, they think they are all replaced with locks. The stop wheel will be more convenient. In fact, the design of our company is also based on actual operating experience.
If the customer is forced to replace the locking wheel, the matters needing attention are as follows: For safety, first disassemble the connecting part of the mobile X-ray vertical bucky stand and the mobile base, then turn the mobile base over and replace the wheels. After ensuring safety, assemble the X-ray vertical film frame with the mobile base. If you still have any technical questions to consult, welcome to consult!
