Crane production procedure
The production procedure for a single beam traveling gantry crane involves several key stages, from design and material procurement to assembly, testing, and final delivery. Below is a step-by-step outline of the typical manufacturing process:
1. Design & Engineering
Customer Requirements Analysis: Determine lifting capacity, span, lifting height, duty cycle, and operating environment.
Structural Design:
Design the main girder (single box or I-beam structure).
Design end carriages (legs/wheels) and runway beams.
Select hoist/trolley type (electric or manual).
Load & Stress Calculations: Ensure compliance with standards (ISO, FEM, DIN, or ASME).
Electrical & Control System Design: Choose motors, brakes, limit switches, and control panels.
2. Material Procurement
Steel Plates & Profiles: High-quality Q235B/Q345B steel for main girders and supports.
Mechanical Components: Wheels, axles, bearings, gears, and couplings.
Electrical Components: Motors, cables, control panels, and safety devices.
3. Fabrication of Main Components
A. Main Girder Fabrication
Cutting: CNC plasma/oxy-fuel cutting for precision.
Welding: Automated submerged arc welding (SAW) for strong seams.
Straightening & Inspection: Ensure proper camber (pre-bend) and check for defects (UT/RT testing).
B. End Carriages & Legs
Frame Assembly: Welded steel construction with reinforced bracing.
Wheel & Bearing Installation: Machined wheels for smooth travel.
C. Hoist & Trolley
Pre-assembled Hoist: Electric chain hoist or wire rope hoist.
Trolley Frame: Fabricated to accommodate hoist movement.
4. Surface Treatment & Painting
Shot Blasting: Removes rust and improves paint adhesion.
Primer & Paint: Anti-corrosion coatings (epoxy + polyurethane).
5. Assembly
Girder & End Carriage Joining: Bolt or weld the main beam to legs.
Hoist/Trolley Installation: Mounted on the girder.
Electrical Wiring: Connect motors, controls, and safety devices.
6. Testing & Quality Control
Dimensional Inspection: Verify span, height, and alignment.
Load Testing:
Static Load Test: 125% of SWL (Safe Working Load).
Dynamic Load Test: 110% of SWL with operational checks.
Functional Tests: Travel, lifting, braking, and limit switch verification.
7. Disassembly & Packaging
For Shipment: Crane may be disassembled into modules (girder, legs, hoist).
Protective Packaging: Waterproof wrapping for sea transport.
8. Installation & Commissioning (On-Site)
Runway Preparation: Ensure level rails or ground support.
Reassembly: Bolt components together.
Final Testing: Operational checks under load.
9. Documentation & Delivery
Manual & Certificates: Include load test reports, CE/ISO certifications.
Training: Operator and maintenance guidance.
