We replaced two of our old chain blocks with 1-ton electric chain hoists from this supplier. The difference in efficiency was immediate. They're quiet, compact, and the remote control makes awkward lifts much easier. Install took less than an hour.
What I appreciated most was the support team. We had some questions about the voltage compatibility, and they walked us through everything. The hoist itself works great — strong motor, responsive control, no unnecessary noise.
