The aluminum alloy hand pulls the gourd tights of 0.75 tons to 6 tons. The aluminum alloy body is high and light. The handwing of the gourd has a upper gear, empty gear, and lower gear. The air gear means that the state is in the state of the air. When the goods need to be rising, hang the cargo under the hook and then pull the handle with your hand, and pull it to the upper position to carry out the rising operation of the goods. If the cargo is needed, then you need to pull the block to the lower position with your hand, and then you can perform a decline operation. During the load, the dial block cannot be adjusted to the empty gear, otherwise the cargo falls and fails.
