HHB型电动葫芦
1.Light weight，compact design and high efficient motor pressing steel structure，high strength body，light and compact.2.Most tensile safety hooks both the top and bottom hook made ofhigh tensile alloy steel，with specialtreatment，it prevents the hook from breaking and being deformed gradually under a sudden extra-load.
3.Compact and nice chain container high strength plastic container have outstanding durability.
4.Limit switch devices fitted at both top and bottom ends，switch off power automatically to prevent load chain from running out.
5.Phase error relay a specially designed current-post，prevent motor from running at incorrect wire connection.
