Working Principle
The principle of locking system
- F1 : The weight of attachment (F1) applies into moving hook perpendicularly to prevent release of attachment from the moving hook.
- G : The turning radius (R) of moving hook overlap (G) with attachment pin to prevent release of moving hook.
- S : The strength of pushing down from spring (S) applies to stabilize the locking system of moving hook.
- S : The strength of pushing down from torsion spring(S) applies to stabilize locking position of the safety latch(red color)
- W : The weight of attachment(W) applies into the safety latch(red color) to prevent release of attachment from the fixed hook.
