Multifunction hoist is a hoist. Electric chain hoist is suitable for ground and air use., Is widely used in the construction industry. Hoist maintenance, with a transmission capacity, lifting height, stable and reliable operation of the other major advantages. Multifunctional Hoist model: nominal weight of 300 ~ 600kg, 500 ~ 1000kg maximum lifting height: 100M lifting speed: 8M / MIN; 5.5M / MIN rated voltage: 220v; 380v electrical power is not as follows: 1.5kw, 1KW, 1.5KW electric hoist, 0.4KW; Power supply: single-phase and three-phase two kinds. Advantages wire rope hoist is a small length dimension, the motor mounted on the inside of the drum hoist. Compact electric hoist structure, the motor axis is perpendicular to the axis of the hoist drum using a worm gear. The disadvantage is: the length dimension, large width aspect size, structure clumsy, low mechanical efficiency, processing more difficult and so on. Dual control hydraulic system, the overflow valve, magnetic contact pressure gauge pressure can be accurately controlled. Electric control unit uses a low voltage control, increased security dominate the system, has not produced to the structure type of product. Structure and characteristics: The machine uses a mechatronic design, changing different molds, it can suppress the different specifications of wire rope electric hoist hh dominate simple, safe. Its main drawback is the motor cooling premise poor, poor packet, inspection, equipment, easy maintenance motors, power supply unit complex. Electric motor axis parallel to the axis of the mandrel electric hoist, wire rope hoist advantage of its height and the length of the small size. The disadvantage is the width of the large size and poor groups, manufacturing and assembly complex. _ Generous heavy hoist attachment (certified) _ Xi'an hoist is provided by generous heavy machinery Co., Ltd., Henan Province.
