20 Ton Gantry Crane Specifications

The following table lists key specifications for common 20 ton gantry cranes, facilitating comparison. Parameters include capacity, span, lifting height, and working duty, sourced from typical designs and customizable based on actual conditions.

Parameter Notes and Selection Tips:

• Span: Determined by site track and ground conditions; larger spans require more robust main beam designs and increased material usage.
• Lifting Height: Should align with the maximum lifting height required on-site, with sufficient safety clearance.
• Working Duty: Reflects usage frequency and intensity (e.g., A3, A4, A5); higher duty levels require more durable lifting and travel systems.
• Control Method: Common options include ground remote control and cabin control, selected based on operational safety and visibility.
• Environmental Protection: Outdoor use requires considerations for anti-corrosion, wind resistance, waterproof electrical protection (e.g., IP ratings), and protection against freezing or dust.

20 Ton Gantry Crane Price

The following prices are market reference prices sourced from suppliers and project contract examples. Actual prices may vary significantly due to customization, material cost fluctuations, transportation and installation conditions, and contract terms.

Note: Prices given in the table are for general reference only, actual prices may vary depending on the specific customisation or additional features required for the project.

Summary of Price Influencing Factors:

• Structure Type: Double girder > single girder (higher material and manufacturing complexity).
• Span and Lifting Height: Larger spans and heights increase steel usage, significantly raising costs.
• Working Duty: A5 and other high-frequency, heavy-load conditions require higher-spec motors, brakes, and reducers, increasing costs.
• Electrical/Control/Safety Features: Cabin control, variable frequency control, explosion-proof or anti-corrosion coatings, automation, and positioning systems add to costs.
• Transportation and Installation: Costs for transporting large components, on-site installation, commissioning, and certification are significant.

Recommended Procurement Process: Before requesting a quote, outline your requirements (lifting capacity, span, lifting height, working environment, control method, indoor/outdoor use, explosion-proof or corrosion-resistant needs, and preferred control options).

Conclusion and Procurement Recommendations

1. Define Conditions Before Quoting: Prepare details such as lifting capacity, span, lifting height, working frequency (duty), indoor/outdoor use, control method, protection/anti-corrosion requirements, and special features (positioning, weighing, variable frequency control).

2. Prioritize Duty and Safety: For frequent operations (A4/A5), opt for double girder cranes or higher-spec main units with redundant designs; critical projects should choose reputable manufacturers with proven electrical control systems.

3. Consider Total Cost of Ownership: Beyond purchase price, factor in transportation, installation, commissioning, certification, maintenance, and spare parts supply, which are crucial for large equipment.

4. Balance Customization and Standardization: Standardized modules reduce costs and speed up delivery, but specific conditions (e.g., high winds, coastal corrosion, extreme temperatures) require customized protection.
