Two - maxillary four - rope grapple (two - maxillary bucket)
- This is a kind of load gripping, which is used during loading and unloading operations with lumpy and bulk materials (sand, slag, rubble, gravel, coal, etc. ). It is used on gantry, bridge and tower cranes, as well as on excavators instead of the usual bucket.
A four - rope grapple is a grab, in which lifting operations perform two ropes, called lifting or supporting, and opening and closing the grab also perform two ropes (called closing or closing).
Advantages of the four - rope grab:
1. Reduced rope wear.
2. The possibility of creating a large effort to close the grab (in comparison with single - line grabs).
Disadvantages of a four - wire grab:
1. The need for equipment lifting mechanism double - drum winch.
2. Loss of time with a frequent change of load gripping bodies (time is required to re - load hoisting ropes).
Four - rope double - jaw grapples are divided according to the type of overloaded load.
