Crossite Sleeper Prestressing Wire Stranding Machine With DIN1120 Bobbin Size
Equipment description:
1.Skip stranding machine 1+6×1120
For the skip stranding machine, each set consists of 7 pieces of 1120 bobbins, is driven by single motor. The transmission shaft and Rotating body are connected by synchronous belt. With stable lay pitch, it guarantees the lay lengths of stranded wires in different dimensions are in accordance with GB/T5224-2003. Big size bearings support the threading barrel to get enough space and make threading very easy. Each revolving part are connected with one another by a GRP cambered plate, which enables it reach the speed request of higher stranding machine. 7 single wires pass through each own position without interference with each other. The bracket of cylinder escapement is movable, makes it easier for transfer and balance adjustment. Damping system is loaded on the bracket to adjust the mutative tension of each single wire during production. Integrative bottom frame can make sure the bunching machine works steadily.
