Qy Type 250t Overhead Crane

1.Light load lifting light load lifting weight Q = 0.4Gn lifting step drive, each file must stay 1 seconds from the stationary speed to the rated speed, usually need to go through more than 5 seconds. When the hook is raised to a predetermined height, should be gradually pulled handle zero, each file will stay for more than 1 seconds, the motor slowed down and finally stop. 2.Load lifting load lifting weight is Q 0.5Gn-0.6Gn start, slow acceleration, when the handle is pushed to the direction of the first gear, stay 2 seconds, in the stepwise acceleration of each file must stay for 1 seconds. When the hook is raised to a predetermined height, should be gradually pulled handle zero, the motor slowed down and finally stop. 3.Heavy lifting heavy lifting weight Q more than 0.7Gn lifting should be quickly pushing the handle to the second, the object gradually lifted. Lift the object after gradually accelerated, if the handle is pushed to second after the motor can not start, means that the lifted object has exceeded the rated capacity, it should immediately stop. When the object is raised to a predetermined height, should be gradually pulled handle zero, stay in the second time should be slightly longer, to reduce the impact, but can not stay in the first tranche, to quickly regain the zero weight to prevent decline
