30t Single Beam Gantry Crane With Electric Hoist

Key Features & Benefits

1. Single Beam (Girder) Design

Lightweight yet strong – Made from high-quality steel (box-type or I-beam construction).

Cost-effective – More affordable than double girder cranes while still handling 5-ton loads efficiently.

Space-saving – Requires less headroom than double girder cranes.

2. Electric Hoist System

Types of Electric Hoists:

Chain Hoist (e.g., CM Lodestar, Kito, Yale) – Best for frequent, medium-duty lifting.

Wire Rope Hoist (e.g., Demag, ABUS, GH) – Smoother operation for heavy-duty use.

Hoist Controls:

Pendant control (wired, hanging remote).

Wireless remote (for safer, long-distance operation).

Variable speed (for precise load positioning).

3. Mobility & Adjustability Options

Fixed Gantry – Stationary, bolted to the floor for permanent use.

Adjustable Height – Telescopic legs for different workspace needs.

Mobile Gantry – Equipped with wheeled legs (manual push or motorized travel).

4. Safety & Reliability

✔ Overload protection – Prevents lifting beyond 5-ton capacity.
✔ Limit switches – Automatic stop at maximum height/travel.
✔ Emergency stop button – Instant power cutoff for safety.
✔ Anti-sway control (optional) – Reduces load swinging.

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.
