Heavy-Duty Leaf Chains for Warehouse Sky Stacker Lifting

Heavy load leaf chains are tailor-made lifting components dedicated to warehouse high-rise stacker machinery. Constructed with thick steel plates and solid bearing pins, they deliver stable vertical load-bearing capacity to meet frequent stacking, retrieving and cyclic lifting tasks in automated storage facilities.

Core Specifications

• Raw material: High tensile alloy steel, fully heat treated

• Structure: Multi-layer stacked leaf plate design for boosted load limit

• Processing: Precision riveting, tight hinge clearance control

• Performance trait: High breaking force, outstanding anti-fatigue property

• Custom options: Custom length, connecting ends and assembly accessories

Key Advantages

1. Extreme Load-Bearing Capacity

   Multi-sheet laminated structure distributes lifting pressure evenly, capable of holding heavy pallet loads during high-rise warehouse storage and retrieval without permanent elongation.

2. Stable Reciprocating Lifting Performance

   Eliminates jitter and unbalanced pulling during fast vertical travel of sky stackers; compact hinge design ensures smooth retraction and extension.

3. Long Service Life Under Cyclic Workloads

   Integral quenching and tempering eliminate internal metal stress, resisting repeated start-stop lifting fatigue common in round-the-clock automated warehouse operation.

4. High Safety Factor for Storage Equipment

   Strict tensile strength testing ensures low risk of chain fracture during high-position cargo handling, lowering equipment breakdown and goods damage risks.

5. Low Maintenance Operation

   Polished inner hinge surfaces reduce friction loss, lessening regular lubrication frequency and cutting warehouse daily maintenance expenditure.
