Material Properties

• Cast Iron Counterweights
   Inherent metal strength and durability
   Dense structure resists deformation
   Fully sealed against corrosion

• Cement Counterweights
   Economical concrete core
   Requires metal casing for impact protection
   Vulnerable to cracks under thermal stress

Application Principles

  Heavy-Duty Operations (Ports/Steel Mills)
 Cast iron maintains stability under sustained loads

  Light Indoor Applications (Warehouses/Packaging)
 Cement provides cost-effective basic performance

  Environmental Warnings
 Freezer environments: Cast iron prevents frost damage
 Coastal areas: Cement casing susceptible to accelerated rust

Safety Performance

• Cast Iron: Absorbs impact energy without fragmentation

• Cement: May shatter under severe force, requiring guards
   High-risk sites mandate cast iron protection

 3-Step Decision Protocol

1. Assess Scenario
   → Extreme temperatures/humidity? Choose Cast Iron
   → Standard indoor loading? Cement suffices

2. Verify Standards
   → Industry regulations (e.g., hazardous storage) → Prioritize compliance

3. Evaluate Longevity
   → Usage beyond five years? → Cast iron lowers lifetime costs
