Component Specifications

Definition
A counterweight frame is a rigid structural assembly designed to securely mount and position counterweights within industrial machinery, particularly in the upper structure or house of equipment like cranes, presses, or injection molding machines. It distributes load forces, maintains balance during dynamic operations, and prevents excessive vibration or tipping, thereby enhancing machine safety, precision, and longevity.
Working Principle
The counterweight frame operates on the principle of static and dynamic balance. It provides a stable mounting platform for counterweights, which offset the weight of moving components (e.g., booms, arms) to reduce net torque and inertial forces. This minimizes stress on motors and structural elements, ensuring smooth operation and preventing mechanical failure due to imbalance.
Materials
Typically constructed from high-strength steel (e.g., ASTM A36 or A572 Grade 50) for durability and load-bearing capacity. May include welded or bolted assemblies with corrosion-resistant coatings (e.g., galvanized or powder-coated) for harsh environments.
Technical Parameters
  • Dimensions Customizable per machine design
  • Mounting Type Bolted or welded to machine base
  • Weight Capacity 500-5000 kg
  • Load Distribution Uniform across frame structure
Standards
ISO 12100, DIN 15018
