Metallurgical Electric Hoist using note note: 1, under - 10 ℃ low temperature or above 50 ℃ high temperature environment, 2, with explosion danger and full of places of sulphuric acid and other corrosive gases, 3, in lifting ban the use of toxic ratchet lever block, flammable, in order to ensure safe and reliable According to hoisting speed, electric hoist is divided into two kinds, single speed and double speed is divided into fixed and operation type two kinds. Force more force electric hoist, complete kinds, superior performance. High quality advanced technology production. The good faith quality, to provide users with a variety of electric hoist quality products services. Group of crane electric hoist is widely used in all walks of life processing workshops, warehouses, docks, and various kinds of modernized production line ratchet lever block, the assembly line. In workplace less space to use more flexible fast, safe and convenient, is suitable for construction projects in the field of climbing frame, the ascension of climbing form, large oil tank group of crane. Group of crane electric hoist mechanism is compact, small size, light weight, high efficiency, easy to use, reliable braking simple maintenance. Riedel in crane electric hoist, the overall design, easy to use, performance is superior, the collection of electric hoist and chain blocks with the advantages of an organic whole, work by disc brake motor, driving speed reducer reducer. Ratchet lever block group of crane electric hoist is a kind of low speed chain electric hoist, suitable for small space in the workplace. Climb in the field of construction engineering, the ascension of climbing form, large oil tank group of crane, and so on various occasions.
