石家庄五一牌手拉葫芦经销商 五一牌手拉葫芦产品特点: 1.结构简单,维修起来很方便 2.手拉力小、工作效率高、省时省力。 3.体积小、重量轻、方便携带。 4.制动器拥有防护壳、制动安全可靠。 5.链条和零件都进行很好的打磨,不容易产生卡链,降低噪音。 手拉葫芦是通过拽动手动链条、手链轮转动,将摩擦片棘轮、制动器座压成一体共同旋转,手拉葫芦齿长轴便转动片齿轮、齿短轴和花键孔齿轮。这样,手拉葫芦装置在花键孔齿轮上的起重链轮就带动起重链条,从而平稳地提升重物。 手拉葫芦采用棘轮摩擦片式单向制动器,在载荷下能自行制动,棘爪在弹簧的作用下与棘轮啮合,保证手拉葫芦制动器安全工作。 手拉葫芦具有安全可靠、维护简便、机械效率高、手链拉力小、自重较轻便于携带、外形美观尺寸较小、经久耐用的特点。 (Hand chain hoist is through the pull of the manual chain, the chain wheel rotation, the friction piece ratchet, brake pressure into a whole body, the hand pull the long axis of the gear, gear, gear and spline hole. This device, hand chain sprocket driven lifting chain in spline hole gear, thus smoothly lifting. Hand chain hoist adopts a ratchet friction one-way brake, can automatically brake under load, under the action of the spring pawl is engaged with the ratchet wheel, hand chain hoist brake safety guarantee. The hand chain hoist is safe, reliable, easy to maintain, high mechanical efficiency, low weight, easy to carry, easy to carry, low weight, beautiful appearance, small size, durability.) 购买五一牌手拉葫芦可选择河北骏豪机械设备有限责任公司,河北骏豪机械设备有限责任公司为您提供更安全高效的起重工具!欢迎各位新老朋友来电垂询!
