Product introduction:
The rotating rings, with rotate 360 degree and 180 degree flip function for special occasions, lifting angle. Compared with the traditional screw rings, more flexible and can meet the needs of all aspects. Universal rings made of alloy steel with high temperature and liquid forging. Swivel the rated load of ball bearings can fully rotate. Bolt strength grade is 12. 9 level. (the main material: 42CrMo alloy steel), 6G precision, black antirust processing, to ensure that regulatory inspection pass through threads.
Use requirements:
Rotating (Universal) ring screw must be installed vertically with the workpiece plane, requiring joint surface smooth, tight junction. The rings must be adjusted to the stretching direction, and remain free to rotate, and avoid sharp body contact. The rings must have professional personnel to operate, and sling connection, should maintain the hanger and the connection rings rotate freely, professionals should conduct regular safety testing.
Matters needing attention
Please select the appropriate 1 rotating rings according to the needs, do not exceed the rated load, the rotating rings engraved with rated load;
2 in the hole to make the workpiece upside eyebolt is vertically arranged on the surface of the workpiece. Threaded holes should be drilled to avoid heavy twist top lines are swell rings;
3 the workpiece surface must be flat, so that the rings washers and workpiece surface contact, without clearance;
4 do not install padding between the ring gasket and workpiece surface;
5 after installation, the side rings U bolt can not be touched by hanging or other objects;
6 lifting, please uniform load, strength gradually, do not apply impact load and vibration load;
7 rotating rings used, eyebolts may gradually loosening, tightening torque must be redefined again; care should be regularly checked and tighten the bolts to iron mechanical torque recommendation;
8 rotating rings must use special bolts and nuts;
9 rotating rings is not suitable for full speed rotation.
