Industry-Verified Manufacturing Data (2026)

Spreader Frame

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Spreader Frame used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Spreader Frame is characterized by the integration of Longitudinal Beams and Cross Members. In industrial production environments, manufacturers listed on CNFX commonly emphasize High-strength steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The main structural framework of a spreader that supports and integrates all other components.

Technical details and manufacturing context for Spreader Frame

Definition
The spreader frame is the primary load-bearing structure of a spreader machine, typically constructed from welded steel sections. It provides the rigid foundation upon which the hopper, conveyor system, spreading mechanism, and power unit are mounted. The frame's design determines the machine's overall dimensions, weight distribution, and structural integrity during operation.
Working Principle
The frame functions as a static structural element, transferring operational loads (material weight, vibration, and dynamic forces from movement) to the ground via the undercarriage or wheels. It maintains alignment and positional relationships between all attached components to ensure coordinated machine function.
Common Materials
High-strength steel, Alloy steel
Technical Parameters
  • Overall length, width, and height dimensions of the frame structure. (mm) Customizable
Components / BOM
  • Longitudinal Beams
    Primary longitudinal load-bearing members running the length of the frame.
    Material: steel
  • Cross Members
    Transverse structural elements that connect longitudinal beams and provide lateral rigidity.
    Material: steel
  • Mounting Plates/Brackets
    Attachment points welded to the frame for securing other machine components (hopper, conveyor, engine).
    Material: steel
Engineering Reasoning
150-450 kN static load capacity, 0.5-2.5 m/s dynamic loading frequency
Yield stress threshold of 355 MPa for S355 structural steel, buckling at slenderness ratio > 120
Design Rationale: High-cycle fatigue from cyclic bending moments exceeding 10^6 cycles at stress amplitude > 200 MPa, leading to crack propagation at stress concentration points
Risk Mitigation (FMEA)
Trigger Corrosion-induced section loss exceeding 15% of original cross-sectional area
Mode: Reduced moment of inertia causing excessive deflection > L/250 under design load
Strategy: Hot-dip galvanizing to 85 μm zinc coating thickness with sacrificial anode protection
Trigger Resonant vibration at natural frequency of 8-12 Hz matching crane hoisting frequency
Mode: Amplified stress concentration at welded joints exceeding fatigue limit of 160 MPa
Strategy: Tuned mass dampers with 2% critical damping ratio and frequency detuning through stiffener redesign

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Fatigue cracking at weld joints
Cause: Cyclic loading from operational stresses and vibration, often exacerbated by poor weld quality or design stress concentrations.
Corrosion-induced structural weakening
Cause: Exposure to harsh environments (e.g., saltwater, chemicals) without adequate protective coatings or material selection, leading to pitting and material loss.
Maintenance Indicators
  • Visible cracks or deformation in structural members
  • Unusual noises (e.g., grinding, popping) during operation indicating loose or failing components
Engineering Tips
  • Implement regular non-destructive testing (e.g., ultrasonic, magnetic particle) on critical welds and stress points to detect early fatigue damage.
  • Apply and maintain protective coatings (e.g., galvanization, epoxy) and ensure proper drainage to prevent moisture accumulation and corrosion.

Compliance & Manufacturing Standards

Reference Standards
ISO 10243:2010 (Compression springs for press tools - Technical specifications) ANSI B11.19-2019 (Performance Criteria for Safeguarding) DIN 2095 (Cylindrical helical compression springs made from round wire and bar - Quality specifications)
Manufacturing Precision
  • Bore diameter tolerance: +/-0.05mm
  • Parallelism of mounting surfaces: 0.1mm per 100mm
Quality Inspection
  • Dimensional verification with CMM (Coordinate Measuring Machine)
  • Load testing to verify spring force characteristics
