DONGBO CHAIN 10 (Leaf chain)
Technical Data
Leaf Chain :
Dong Bo Leaf chains consist of only simple Link plates held together by riveted pins for a high strength linkage. Combined with their greater tensile strength and directional flexibility, they find excellent applications, such as balance or counterweight, lift truck, fork lifts and other lifting machinery, which more at low speed.

There are two kinds of end clevises for outer and inner links. End clevis should be heat treated alloy steel because it requires strength.
Type -A Leaf Chain (Standard series) :
Plate exterior, thickness and pin external diameter are identical to those of ANSI Standardroller chains with same pitch.

Note) Plate layouts and dimensions of A, B type Leaf Chains can be custom-made according to order.
Type -B Leaf Chain (Heavy series) :
The plate exterior is identical to that of the ANSI StandardRoller Chain, but the plate thickness and the pin external diameter are identical to those of the Roller Chain one size larger.
