Spur gear casting ladle is better than traditional worm gear:
The spur gear drive is similar to the wear-free rolling friction, which has an efficiency of 97%. But self-locking worm gear is sliding friction and is easy to wear. Its efficiency is 30%, so the spur gear casting ladle is wear-resistant and light. Detailed explanations are given in the following pages, with cases and videos. You can collect URL, spare.
The 0.5t spur gear casting ladle is a small ladle. It uses one brake and the safety shaft has no tooth surface conversion; it is definitely not like a worm gear ladle, which collides after wear.

The hand chain hoist is driven by a gear, and the screw load brake is self-locking. The spur gear casting ladle also uses this principle, so it is as easy to use as a hand chain hoist.
Hand chain hoist: hand pull its zipper, it lifts heavy objects. When the hand releases it, it stops and locks itself. Pull it again and go on.
Pull the zipper on the other side, and it will land. When the hand releases it, it stops and locks itself. Pull it again and then it down. It operates freely, and is widely used.
