Dongbo AL-Type Leaf Chain (Standard)
Appearance and thickness, an external diameter of plate are the same as Standard roller chain on marked same pitch.
The AL series can handle light shock and is typically used for suspension of counterweights and fork lifts.
Plate exterior, thickness and pin external diameter are identical to those of ANSI Standard roller chains with same pitch.
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.
