Two sets of guidance sets carry out work, and guidance set is preferably two sets or four sets.To be installed on before the side of crane
Two sets of guidance sets of rear end are introduced.
Two range sensors 3 come measure certain side of crane 1, front and back end relative to running track 7 horizontal range.Such as
Really the distance of two measurements keeps constant during crane traveling or is maintained within the scope of setting, illustrates crane
Traveling track is straight line or is similar to straight line, and traveling is good, without adjustment.Also, from this measurement level away from
From, it can also be seen that drift condition and skew side, namely offset to which side.
If the distance of two measurements exceedes the scope of setting during the traveling of crane 1, and trend is increasing
When, illustrate the straight line of the traveling track increasingly offset track of crane, at this moment, the control system of crane is automatic (or manual)
The drive mechanism 4 that instruction is arranged in crane side, two guiders of front and back end promotes horizontal guide sheave 5 to skew
Side is moved a certain distance, in the presence of horizontal guide sheave 5, and crane 1 gradually moves towards defined running orbit (straight line), so
It is achieved that self guided effect.Below by taking bridge crane as an example, describe in detail as follows：
