It has been generalized that worm gear winches have a slower line speed and are less efficient than other designs. However, they can be self-braking, meaning that they stop when the driving worm gear stops which is make the process safer. This product is also extremely robust. If you are an industry that requires line speeds that are equal to planetary counterparts, then try the technologically advanced worm gears.
