Frequently Asked Questions
How does JL62-07 differ from JL62-89?
Ratings are equivalent (4.5 kN working, ≥13.5 kN breaking); the -07 is the later design with material options of 20# seamless steel or Q235A — confirm the drawing your design cites before ordering.
What loads does it carry?
Maximum horizontal working load 4.5 kN with tensile withstand 6.75 kN and breaking load at least 13.5 kN.
Which material should I order?
Follow your design drawing's material call-out; both variants are die-forged and hot-dip galvanized with identical interfaces.
What does it mount?
The locator, together with the registration bracket family — the tube is the adjustable backbone of the registration point.
