Lifting Frames

Following installation and commissioning, lifting frames can operate independently, providing both lifting and self-launching mechanisms. While the gantry crane is used for medium and large projects, this method is suitable for smaller, long span structures (30m to 170m). It is particularly versatile and applies both to precast segmental decks and cable-stayed decks (either precast, composite, or steel) regardless of span range and segment weight. The equipment can be reused for other projects.

Segment Lifting Frames

Segment lifting frames are specialized equipment used in bridge construction, particularly for precast segmental decks. They are designed to lift and position prefabricated bridge segments with precision and efficiency. Here are some key features and types of segment lifting frames:

• 1. Static Lifting Frames: These lift segments from the tip of an already erected cantilever.
• 2. Mobile Lifting Frames: These can lift segments from any position on the ground or underneath the erected deck.
• 3. Mobile Lifting Frames with Rear Feeding: Ideal for low-clearance areas, they pick up segments stored on top of the erected deck.
• 4. Special Mobile Lifting Frames: Suitable for projects with limited access, lifting segments from a single position on the ground.

These frames are versatile and can be adapted for various bridge types, including cable-stayed bridges. They offer benefits like high productivity, precise placement, and reduced disruption to existing infrastructure.
