What’re the instruction of speed of crane?
The working speed is also called rated working speed, every working mechanism has each working speed.
1) rated working speed Vn: the fetching device’s lift velocity of the lifting mechanism motor at the rated rotating speed(m/min).
2) crane(cart) traveling speed Vk: the gantry crane’s traveling speed of the crane’s motor at the rotating speed(m/min).
3) trolley traveling speed Vi: the crane’s traveling speed of the crane’s motor at the rotating speed(m/min).
4) the variable speed Vr: in stable state, the rated load’s average speed of the horizontal displacement in the variable plane.
Distance from the ground 10m, the wind speed is less than 3m/s, the crane in the plane, the range’s average speed (m/min)from
the max. speed to the min.speed.
