2.  WJK clamp base and T bolts are spherical hinge connection. The clamp can relieve the impact on rails, crane beams, brake systems, which extend the longevity of crane systems. 

3.  WJK clamp with a adjustable wedge plate, with dual self-lock tightening mechanism, prevent loose in application.

4.  T Bolt and upper plate of WJK rail clamp are easily disassemble and assemble, which is convenient for installation and maintenance.    

5.  Upper plate of WJK clamp well fit rail section curvature.

6.  WJK clamp installation space depend on different crane.
Q≤275t, 600mm space

Q>275t, 500mm space    

7. Rail clamp base is made of weldable grade steel Q345, using low hydrogen electrodes. Recommended electrodes E4315, E5015.    

8. Two side welding should be used for A4-A5 middle duty crane. Three side welding should be used for A6-A7（A8）heavy duty crane.

9. Tightening torque Q ≤275t(150N.m)

Tightening torque 220N.m for heavy duty crane.  

10. Max. side load: 45KN
