Bridge construction gantry crane

Segmental launching bridge construction gantry crane is used in the construction of precast segmental viaducts for span-by-span and balanced cantilever methods. There are various types of launching gantries available, the choice of which depends on the geometrical site and construction sequence adopted by the designer.

Segment launching bridge construction gantry crane with precast segment bridge construction method is widely used for both highway and railway bridges. The precast segmental girder is installed as a set along the entire length of the span, and then prestress is introduced into the structure through external tendons, and the span-by-span method is faster to construct and requires fewer workers than the balanced cantilever method of erection. It is designed and fabricated to ensure high performance, efficiency, safety, flexibility and multiple successive uses.

Designed to meet the rigorous demands of bridge construction, SEVENCRANE’s gantry cranes deliver unmatched performance:

• Increased Productivity: High-speed lifting and precise load positioning accelerate project timelines.
• Suitable for Various Yard Conditions: Adaptable to uneven terrain, outdoor weather extremes, and confined workspaces.
• Low Energy Consumption: Energy-efficient motors and regenerative drives reduce operational costs.
• Stable Operation: Robust steel structures and anti-sway technology ensure safety under heavy loads (up to 500 tons).

SEVENCRANE’s cranes are engineered to handle steel girders, pre-cast segments, and construction machinery with reliability, making them indispensable for modern bridge-building projects.

SEVENCRANE’s bridge construction gantry cranes are built to last, thanks to our meticulous manufacturing process:

1. Material Selection: High-grade steel and corrosion-resistant coatings for durability.
2. Advanced Welding: Automated welding ensures structural integrity and load-bearing capacity.
3. Component Assembly: Precision alignment of girders, trolleys, and hoists for seamless operation.
4. Quality Testing: Load tests, stress analyses, and safety inspections comply with ISO and CE standards.
5. Custom Finishing: Weatherproof paint systems and modular designs for easy on-site assembly.

Choosing the right crane requires evaluating:

• Load Capacity: Match lifting needs to crane specifications (e.g., 25/5T, 50/10T).
• Span: Ensure the crane’s width accommodates bridge components and site layout.
• Lifting Height: Optimize hook height for stacking materials or assembling tall structures.
• Customization & Future Needs: Modular designs allow upgrades for evolving project demands.

SEVENCRANE’s engineers provide free consultations to help clients select or customize cranes that align with their long-term goals.

Costs vary based on:

• Technical Specifications: Higher capacities, spans, or automation increase investment.
• Customization Options: Specialized features like explosion-proofing or remote control add value.
• Operational Requirements: Energy-saving systems or extended warranties impact pricing.
