5 Technical Parameters For Buying A Crane
The main parameters of the 15 ton gantry crane/overhead crane are the parameters that characterize the main technical performance indicators of the crane, and are the basis for the design of the crane, and also an important basis for the safety technical requirements of the crane.
1. Rated lifting capacity Gn
2. Total weight Gz
3. Effective lifting capacity Gp
The lifting height refers to the vertical distance from the top surface (or ground) of the crane running track to the upper limit position of the pick-up device, and the unit is m. Usually, when using a hook, it is counted to the center of the hook ring; when using a grab bucket and other containers, it is counted to the bottom of the container.
1. Descent depth h
When the pick-up device can be placed below the ground or the top surface of the track, its lowering distance is called the descending depth. That is, the vertical distance between the lowest working position of the spreader and the horizontal support surface of the crane.
2. Lifting range D
The amplitude of a rotating jib crane refers to the horizontal distance between the center line of rotation and the plumb line of the pick-up device, in m. The amplitude of a jib crane of the non-rotating type refers to the horizontal, horizontal distance between the centerline of the spreader and the rear axle of the jib or other typical axis.
1. Lifting speed Vq
2. Cart running speed Vk
3. Car running speed Vt
4. Luffing speed V1
5. Walking speed V
6. Rotation speed ω
