For shipyards or ship owners, they can use our electric winches to pull the vessel out of the water for repairs or maintenance. In addition to the AQ-JM electric winch in this case, the AQ-JMM friction electric winch is also a popular choice for pulling boats. We offer our customers two options: use airbags or a rail cart to pull the boat.
You can pull ships ashore using airbags, which have numerous advantages and benefits:
Rail cart is a more traditional way of helping to pull boats out of the water. It is more often found in small tonnage ships. In addition to electric winches, we also provide other accessories required for pulling the boat, including movable and fixed pulleys, guide pulleys, cables, etc.
