The Multifunctional Traction Bed for Cervical and Lumbar Regions JYZ-IIIA is a three-dimensional multifunctional traction bed for cervical and lumbar regions with computer control. The traction bed uses a telescopic motor for traction drive. It can perform ladder traction with intermittent traction, periodic traction, periodic reduced traction, and traction, ladder drawing repeatedly, repeatedly repeated type of lowered traction, continuous type and continuous type of ladder traction, as well as any drawing method in traction for automatic compensation, traction is relatively constant, the traction effect is more significant.
