Household mini electric hoist on the retaining device

1, the overall use of anti-off device is about 5mm steel plate welded to ensure adequate rigidity,Manual block difficult destruction, as well as card-bit capabilities to ensure good strength.
2, retention spring return function, but in the whole anti-off is designed to consider the use of springs and spring force so that the center of gravity because of greater weight reduction after the request of the spring, the spring is very easy to make anti-off device is reset, closure,hoist and trolley to ensure operational flexibility.
3, anti-off devices on both sides of widening and extending to the hook body, leaving a gap of 1mm, the use of ontology card, limiting the scope of the retaining device and move around, on the basis of sufficient strength so that it can not be the slot.
4, anti-off device at the maximum range of motion trajectory to ensure adequate open space, so that the hook spreader activities within the range, and with the scope of activities of the retaining device interference,lever hoist so as not to interfere with the rope hanging take work.
5, the operation flexible and reliable, spring installation easier.
6, versatile, easy to make, easy operation, low cost, high reliability, difficult to damage.
7, due to the overall strength, increase reliability depression, difficult damage, so the pin with a diameter of 5mm on the rivet, the person operating the artificial removal. Because different dimensions 2T hook still have subtle differences
