Gantry Crane

Name: Gantry Crane
SKU: 0

The gantry-type lifting machine is a specially designed gantry lifting equipment for bridge construction scenarios. It mainly consists of a modular main beam (including box-type and truss-type structures: the box-type is formed by steel plate splicing, suitable for high working levels; the truss-type uses round steel, angle steel, square steel, etc., mostly used for low working levels), legs, a hoist or trolley, and other components. The components are connected via pins and high-strength bolts, featuring 'easy installation, easy disassembly, and easy transportation' characteristics, and can meet the needs of frequently changing construction sites.

Equipment Description

The gantry crane is a portal-type lifting equipment specifically designed for bridge construction scenarios. It mainly consists of a modular main beam (including box-type, truss-type structures: the box-type is formed by steel plate splicing, suitable for high working levels; the truss-type uses round steel, angle steel, square steel, etc., mostly for low working levels), legs, hoists or trolleys, and other components. The components are connected via pins and high-strength bolts, featuring "easy installation, easy disassembly, and easy transportation," and can meet the needs of frequently changing construction sites.

The equipment is equipped with large trolley travel, beam lifting and lowering, and beam travel mechanisms. The operation modes support wireless remote control, cabin operation, and even dual-mode switching (e.g., aerial operation cabin + remote control mode). It can complete precast beam transportation tasks through "single unit with dual hooks" or "dual units with coordinated lifting," combined with intelligent skew correction and anti-sway technology, enabling stable beam lifting and lowering with precise positioning.

Application Fields

Widely used in the entire process of bridge construction and related heavy-duty fields:

Core Scenarios: Beam fabrication yard (transporting precast beams from the fabrication platform to storage platforms and beam carriers), railway bridge projects, highway bridge projects, subway projects, and elevated bridge construction, responsible for the lifting and relocation of precast beams. It can also assist in the assembly and disassembly of bridge machines and low-height temporary bridge equipment.

Extended Scenarios: Large component lifting operations in industries such as wind power and aerospace (e.g., wind turbine component transportation).

Product Advantages

Outstanding Lifting Capacity: A single gantry crane can lift hundreds of tons (some models can lift up to 900 tons). It can also meet heavier load requirements through "dual-unit coordinated lifting," efficiently completing large precast beam lifting tasks and significantly improving the efficiency of bridge component transportation.

Easy Disassembly and Transportation: Modular design with "pin + high-strength bolt" connections simplifies disassembly, facilitating quick relocation between different construction sites and reducing preparation time and costs.

Intelligent and Efficient Operation: Equipped with wireless remote control, intelligent skew correction, and variable frequency drive systems, it enables "stepless speed regulation," reducing startup impact and extending equipment lifespan. Some models support "inch movement," "micro-speed," and "zero-speed suspension" functions, further improving positioning accuracy and operational efficiency while reducing manual operation difficulty.

Strong Stability and Safety: The main steel structure undergoes finite element simulation analysis, ensuring excellent strength, rigidity, and stability. It also features anti-sway technology (avoiding beam collisions), multiple limit protections (preventing overloading and boundary breaches), and wind-resistant design (suitable for high-altitude and windy environments), ensuring all-round construction safety.

Durability and Adaptability: Made of high-performance steel such as Q355B and Q460C, combined with mature manufacturing processes, the equipment has a long lifespan and low failure rates. It can adapt to various harsh construction environments (high/low temperatures, humidity, etc.), reducing long-term maintenance costs.
