You know that moment when your industrial cart or workbench has a busted wheel, and changing it feels like a wrestling match?
Yeah, Ningbo Shangxin Caster (yeah, I know the name says "CATER" sometimes – typo happens, but it's us) totally gets it.
On June 4, we shipped out another 1,500 pieces of our Japanese‑style floor locks. These little guys come in 4‑inch, 5‑inch, and 6‑inch sizes – perfect fit for carts or industrial trolleys that already use the same size casters.


What are they for?
They're special floor locks for replacing or repairing wheels. You step on the side brake system – super easy, no need to be a gym athlete. And the best part? That side brake won't cut your feet (ouch, we've all been there). Customers who've received them already say "Man, this is so smooth to operate."
Load capacity?
Between 250 kg and 300 kg, depending on the size. Solid enough for warehouse trolleys, assembly line carts, you name it.
How long have we been doing this?

This is our 6th year exporting floor locks for overseas warehouse carts. Six years. So yeah, we've seen a thing or two. We know what bothers buyers – wheels that won't lock tight, brakes that hurt your foot, or floor locks that feel cheap after two months.
Our edge vs. other guys:
Better price for the quality (no, seriously – we keep costs lean without breaking stuff).
Strict quality control – not just paper talk.
Real solution to the pain point: easy wheel change, stable locking, no scratched floors, no bloody toes.
So if you're sourcing floor locks for warehouse carts, industrial trolleys, or any mobile equipment that needs a reliable parking brake – give us a shout. We speak real English, we reply fast, and we don't write like robots.
