1. Different cable reel has a different role

2. Hysteresis type cable reel working principle and scope The working principle of A. Power control system is composed of three phase asynchronous motor and magnetic coupling cable reel. Equipment for cable anchor, electric motor through reducer amplifying torque after work, crane parts driving the reel to rotate winding cable. Adjust the speed difference by a hysteresis driver for this process, ensure synchronous cable and traveling; equipment from the cable anchor, electric motor and the phase sequence unchanged, the runtime dragged cable reel, the magnetic torque is larger than the magnetic drive, synchronous release cable.crane parts The B. control methods and characteristics Hysteresis type cable reel for constant torque output, container cranes for sale the motor must be with the host running gear synchronous starting, while the host stops according to the slide, select the reel motor delay off. If you use multiple hysteresis driver must ensure the motor steering, and conform to the order. Namely: crane, reel motor power, whether positive or reverse the car, the same drum motor phase; cart, reel motor delay off.container cranes for sale C, scope of application The application of cable: Cable cross-sectional area from 10~240mm2; Winding length: 1000 meters; Application equipment: gantry, bridge, gantry crane, blocking reclaimer, gantry crane, bridge crane, bridge, ship loading and unloading machine, double girder grab overhead crane metallurgical machinery, hydraulic machinery and mining machinery and other large rail line equipment.double girder grab overhead crane

3. Cable reel works and Scope a. works As can be seen from the mechanical characteristic curve torque motor, torque motor is a variable torque output. Output at low speed high torque ; metallurgical electric hoist small output torque at high speed, this feature is combined mechanical performance requirements of the cable reel.metallurgical electric hoist When the device towards the ground cable anchor position, torque motor power work, amplifying torque after gear driven rotary winding cable reel. As the winding diameter increases, Torque motor automatically reduce speed and increase the output torque, thus ensuring the closing of the cable line speed synchronization speed carts and maintain constant tension cable received. Leaving the ground when the device cable anchor position, the motor torque constant force direction, dragging the cable carts running, so to generate greater torque motor forward reverse torque, synchronous release cable. b. control and features Power switch motor stall characteristics with long-term, relatively independent of the control system and carts, small gantry cranes just leads from the device to the main power supply switch ( or the total contacts ). Electrical control simple and reliable. small gantry cranes After the big electric car, reel motor powered reel of work, regardless of the cart forward, reverse or stop, the torque motor is always energized and phase sequence unchanged ; After power carts, motor power, reel brake. c, the scope of Applicable cable: cross-sectional area from 10 ~ 185mm2 cable ; Winding length : 800 meters ; Applicable equipment: gantry, bridge, gantry crane, blocking reclaimer, crest door, bridge crane, bridge games, loading and unloading ship machine, double girder overhead crane with trolley metallurgical machinery, hydraulic machinery and mining machinery and other large rail line equipment.double girder overhead crane with trolley
