31. Radius of support, said slewing ring as one of the leading manufacturing enterprises, and scale of existing products can not fully meet the needs of the rapid development of industry.

32. It may be used for slewing conveyers , welding arm and positioner, light, medium duty cranes, excavators and other engineering machines.

33. The single - row four point contact ball slewing ring is composed of two seatring.

34. The QUY55 hydraulic slewing crawler assimilates the new technology and adopts the advanced Electrical parts in domestic and aboard.

35. The slewing mechanism: Stepless speed regulated and frequency control make starting and braking.

36. The rings of slewing bearings with a diameter of several metres are frequently cut into segments for ease of transport or installation.

37. Moreover[Sentencedict.com], a software module used to match the inner and outer rings of slewing ring bearings is developed based on the matching model.

38. Slewing bearings are generally bolted directly to their mating components.

39. The axial-radial roller bearing is a special slewing bearing design.

40. Based on an analysis on the variation of cutting edge length of symmetrically shaped bucket in slewing conditions, a non-symmetrical bucket shape is presented.

41. Also double-row angular contact ball bearings are used as slewing bearings.

42. The lower construction includes the gantry, slewing ring, traversing bogie and balance girder. The electric cable winder and central electricity transmission installations are also included.

43. All have a circular, motor-driven base whose slewing is unlimited by the length of the worm - gear shaft common on smaller cranes.

44. But in the past, it's always based on the experience to design the slewing frame, that is, by analogy or in terms of the principle of material mechanic to design the structure.
