The high-quality China Alloy steel leaf chain of YS STEEL goes beyond the single use scenario of forklifts and is developed to meet the static pressure and reciprocating pulling requirements of various industrial equipment. It covers a complete product matrix of LH/BL heavy-duty, LL light-duty, and AL ultra-light-duty types.

Our Alloy steel leaf chain eliminates the roller sleeves, with multiple layers of chain plates sharing the load. There is no roller wear or jamming, ensuring smooth operation and low noise, and it is suitable for precision lifting mechanisms.
It can withstand constant static tension for a long time, and also cope with frequent start-stop and reciprocating lifting impacts. The performance is stable under alternating loads.
LH/BL heavy-duty, LL light-duty, AL ultra-light-duty are classified designs, allowing for customized selection to avoid overusing large materials or insufficient load capacity.
Apart from the basic hardening and blackening, optional fine polishing, enhanced anti-corrosion treatment can be selected, suitable for different workshop environments such as humidity, dust, and mild corrosion.
Supports non-standard pitch, chain plate array combinations, fixed-length cutting, and end riveting, solving the problems of replacing non-standard equipment with overseas old models.
A1: Plate chain is mainly used for bearing weight, tension, and structural balance, and is not suitable for power transmission; roller chain is mainly for transmission and should not be used to bear large tension for a long time. The two cannot be interchanged at will.
A2: Based on the rated pulling force of the equipment and the frequency of operation, we can offer free technical selection advice to help customers avoid overestimating or underestimating the selection.
A3: Qualified products exhibit extremely minimal deformation under rated conditions; however, excessive load, lateral stress, and severe impact will still cause irreversible stretching. The products must be used in accordance with the specified conditions.
A4: Supports non-standard pitch, special chain plate combinations, fixed-length cutting, end treatment, enhanced anti-corrosion, and is compatible with imported equipment replacement and non-standard complete machine projects.
A5: For the mainstream series, regular inventory is available. Small orders can be delivered quickly; for large orders, production schedules will be followed to execute, and they can be simultaneously aligned with framework agreement cooperation.
