What wind protection devices should be set when working in the open air?
For crane in the outdoor work, should be set rail, anchor device or iron shoes, and must be able to separate non-work state under the maximum when the wind doesn't blow down.
Crane operation brake should be better than the effect of wind device slightly ahead of time, namely wind braking time - clip action time should be lagging behind the operation mechanism of rail braking time, so as to eliminate the crane may produce severe vibration.
The windbreaker should be able to ensure that the crane does not run in the wind when it is not working. The effect of the brake and wheel rim on the side of the rail side of the rail is to be ignored when determining the resistance of the windbreaker.
Clip of rail against the climbing action of general components by its own gravity self-lock condition or the role of the spring, and should not only depend on the drive to achieve the effect of the climb.
The rail clamp is the most widely used in windbreaks, and can be used for various types of cranes. The control method can be divided into: the manual clamp, the electric clamp rail, the flashlight, and so on. In the open-air working crane, the anchor device must be used when the wind speed exceeds 60m/s (10 to 11 winds). When the wind speed exceeds the fixed value, the crane is driven to the anchorage area, and the crane is fixed with anchor and anchor. They are also classified as manual and electric. It will iron shoes and cable anchor function together, through a self-locking function device will track device is fixed in the orbit, in order to prevent the iron shoes and sliding between orbit.
