铝合金手扳葫芦制动器中的摩擦片为摩擦片，所以使用安全、可靠，不会出现质量问题，当手扳葫芦停止上升时能够立即发挥制动效果，使用十分灵敏；
The friction disc in the brake of aluminium alloy wrench hoist is friction disc, so it is safe and reliable to use, and there will be no quality problems. When the wrench hoist stops rising, it can immediately exert braking effect and is very sensitive to use.
最后，铝合金手扳葫芦虽然制动灵敏，但是也需要我们仔细的检查和保养才能保证它的性能不受到影响。例如：如果摩擦片与棘轮之间滴入了油滴而不及时擦干，将会降低摩擦系数，使制动性能降低。
Finally, although the aluminum alloy wrench hoist is sensitive to braking, it also needs careful inspection and www.diandongmenx.cnwww.yanglaoyuanv.cnwww.fumianji.cn www.diandongmenv.cnwww.lvliangbanjia.com.cnwww.yanglaoyuanj.cnmaintenance to ensure that its performance is not affected. For example, if droplets of oil are dripped between the friction disc and ratchet wheel and do not dry in time, the friction coefficient will be reduced and the braking performance will be reduced.
