Hook smooth surface quality requirements , there can be stripped obvious defects , nicks , acute , joints portable electric hoist and cracks , and do not allow welding processing ; should be marked on the hook load capacity, no marked hook should go through calculations to determine load weight before use , and a series of tests ; when the hook severe wear , the opening degree of deformation, torsional deformation , plastic deformation , etc. , should be announced promptly scrapped . In addition , in order to avoid the appearance of security risks in lifting machinery shall be provided with a hook on the hook safety device to prevent decoupling ,                                     View Details

System features: 1) variable frequency speed control system can realize constant torque under rated frequency control of motor speed and constant power above the rated frequency control of motor speed, weak magnetic acc range depends on the motor running to allow for maximum speed and output torque under the highest speed can satisfy the requirement of the load acceleration. 2) the dynamic characteristics of hard, i.e., small dynamic downhill, so are suitable for lifting and running mechanism. Run the speed regulation system of frequency control of motor speed is by regulating the speed stability is better. 3) using open loop or closed loop control of variable frequency and adjustable speed, for application in crane's biggest difference lies in the closed-loop control starting torque is bigger, slow running more smoothly, more wide speed range. General lifting adopts closed loop control, operation using open loop control. With mechanical coupling of motor drive (such as the large capacity lifting mechanism consists of two large reducer was used in electric motor drag, supporting institutions in the two groups before and after the motor through the wheel and track coupling), when using two sets of drive and constitute a closed-loop control respectively, two sets of driving gear should be set between the load balance control function, on the crane, usually can use the following two kinds of load balancing mode: (1) the main device for the speed closed-loop control, from the device for torque control of master-slave control mode (2) the sagging softening characteristic function, two relatively independent load balanced way For two (or two) motor synchronization requirement, can according to the application of the synchronization control of the following ways: 1) speed closed-loop control, synchronization, endowed with the same speed given value, unique location point calibration and correction. (3) the speed closed-loop control, synchronization, endowed with the same speed given value, adopt the absolute encoder real-time position detection correction, absolute position calibration point. When the lifting mechanism adopts star line transmission, two electric motors should be used in order to start the way: 0 ~ 50% by an electric motor running speed range, 50% ~ 100% another motor start, the two motors run at the same time. Slewing mechanism adopts frequency conversion control mode, and usually work in, because of the large load inertia braking state, for, smooth braking, reduce mechanical shock and frequency conversion system torque control mode should be adopted.
