What is Truss Gantry Crane?

The Truss Gantry Crane is a type of lifting equipment widely used in heavy material handling and outdoor applications, characterized by its unique truss structure, which offers both lightweight and high strength. It is mainly used in bridge construction, harbor loading and unloading, large equipment installation, and other scenarios, and has the advantages of strong wind resistance, stable operation, and strong adaptability. This article will introduce the components, uses, and advantages of a truss gantry crane in detail, to help you fully understand this lifting equipment. Please read on:

Components of Truss Gantry Crane

Truss Gantry cranes are mainly composed of the following core components:

• Gantry Frame: It adopts a high-strength triangular truss structure, which is composed of main beam, upper end beam, outrigger, and lower end beam, featuring light weight and strong wind resistance, and is suitable for outdoor operation.
• Hoist Trolley: It moves transversely along the main girder track and is responsible for lifting heavy loads, and can be equipped with an electric hoist or wire rope winch of different tonnage.
• Trolley Travel Mechanism: It adopts frequency conversion control to ensure smooth operation, accurate positioning, and reduce load swing.
• Legs: divided into box structure and steel tube structure, providing stable support and adapting to different ground conditions.
• Walkway & Guardrails: facilitate the safe passage of maintenance personnel, in line with OSHA and other safety standards.
• Electrical System: Integrated with PLC and frequency conversion technology to realize intelligent operation and improve operational efficiency.

Customized Options

Truss gantry cranes can be customized according to the needs of different industries, and common options include:

Operator Cab

Enclosed design, equipped with adjustable seats, non-slip insulated floor, tempered glass windows, optional air-conditioning, audio system, and intercom to enhance operational comfort.

Alimentazione

• Cable Reel: Suitable for working conditions with a wide range of movement.
• Conductor Bar: Suitable for long-term stationary operation, reducing cable wear and tear.
• Safety Features: Including limit switches, overload protection, anti-collision system, etc., to ensure the safety of operation.

Use of Truss Gantry Crane in Different Industries

With its high load carrying capacity, wind stability, and flexible mobility, the truss gantry crane is widely used in the following fields:

• Bridge and building construction: used for lifting prefabricated girders, steel frame handling, and adapted to an open-air strong wind environment.
• Port and logistics play an efficient role in container yard, ship loading and unloading handling, and can resist salt spray corrosion.
• Heavy manufacturing industry: for the assembly and transportation of large machinery, wind power equipment, and pressure vessels.
• Railroad and rail transportation: used in track plate laying, locomotive maintenance, and precise positioning to reduce construction errors.
• Power plant and petrochemical industry: provide stable and reliable lifting solutions in equipment installation and pipeline lifting.

Advantages of Truss Gantry Crane

• Lightweight design: Adopting a square steel pipe truss structure, the whole machine is light in weight, with small wheel pressure, reducing the requirement for foundation.
• Excellent wind resistance: open truss design reduces wind resistance and is suitable for harbor, coast, and other strong wind environments.
• Precise frequency conversion control: both the big vehicle and the lifting mechanism adopt frequency conversion drive, running smoothly, positioning accurately, and reducing load shaking.
• Maintenance-free transmission system: QS three-in-one spline shaft drive is adopted, the reducer is well sealed, with no oil leakage risk, reducing maintenance costs.
• Convenient transportation and installation: modular design, can be quickly disassembled and assembled, low transportation cost, suitable for temporary projects.
