HENAN BAITE, a Top global crane manufacturer, offers a diverse selection of mobile gantry cranes engineered for efficient, safe, and adaptable material handling in various industries. Our main products include: Mobile Single Girder Gantry Cranes, Mobile Double Girder Gantry Cranes, Portable Mobile Gantry Cranes, Rubber-Tired Gantry (RTG) Cranes, and Rail-Mounted Gantry Cranes. We provide cost-effective lifting solutions for heavy-duty projects.These cranes are widely applied in scenarios such as factories, construction sites and warehouses to ports and logistics hubs etc.

Technical Parameters

Static load capacity	1 ton to 50 tons (calculated based on beam deflection);
Height (H)	2m to 10m (customizable, considering lifting height);
Span (L)	3m to 20m (intermediate supports required for spans exceeding 20m);
Width (B)	Determined based on equipment or cargo dimensions (typically 1.5m to 3m);
Dynamic load	A safety factor of 1.2 to 1.5 must be considered during lifting;
Deflection requirements	Typically ≤ L/500 to L/800 (where L is the span);

MOBILE A-Frame GANTRY CRANT PARTS

Horizontal beam(Main Girder or Crossbeam): It is the main overhead support that spans between the legs and allow the hoist to move and lift loads along its length.
A-Frame Leg: (Supporting Columns or Uprights): Vertical supports shaped like an "A" that can enhance stability, often with bracing.In mobile versions, these are typically adjustable (e.g., telescoping) for changing height and can be dissembled for transport and storage.
Base or End Carriages: Universal Wheel base at the bottom of the legs, sometimes with lockable wheels or casters for mobility.This can roll freely in open spaces or be rail-mounted for guided travel.
Lifting Mechanisms: Drives the entire crane's movement; it can be motorized for longer distances or heavier loads, but it is typically manual(push/pull).

Product advantages

High Load-Bearing Capacity & Structural Stability

High-Strength Steel: Steel grades such as Q235 and Q345 offer excellent tensile and compressive strength, capable of supporting loads ranging from several tons to hundreds of tons (customizable design).

Strong Resistance to Deformation: Compared to aluminum or plastic brackets, steel gantry frames are less prone to bending or breaking under heavy loads, ensuring better stability.

Rigid Structure: Welded or bolted steel frames effectively resist vibration and impact, making them suitable for lifting precision equipment or heavy cargo.
Durable & Long Service Life

Wear Resistance: Steel surfaces have high hardness, resisting wear even with prolonged use, particularly suitable for high-frequency operational environments (e.g., logistics warehouses).

Corrosion Resistance: Through painting, hot-dip galvanizing, or powder coating processes, corrosion resistance can be significantly enhanced, making them suitable for humid, outdoor, or industrial corrosive environments.

Low Maintenance Costs: Regular inspections for rust and loose bolts are sufficient, with no need for frequent component replacements.
Flexible and Customizable

Adjustable Dimensions: Parameters such as span, height, and load capacity can be customized according to specific requirements (e.g., narrow aisle warehouses or ultra-high factories).

Modular design: Some steel gantry cranes are bolted together, allowing for quick disassembly or expansion of functionality (e.g., adding tracks or electric hoists).

Multi-functional compatibility: Can be used with various lifting tools such as manual hoists, electric hoists, or hooks.
High Safety

Anti-overturning design: Stabilized through diagonal braces, counterweights, or anchor bolts, offering significantly greater stability than simple scaffolding.

Clear load capacity labeling: Standard steel gantry cranes are marked with their rated load capacity, reducing the risk of overloading.

Fire-resistant and flame-retardant: Steel is non-flammable, making it suitable for high-temperature work environments (e.g., welding shops).
Economic Advantages

Moderate Initial Cost: Though more expensive than wooden or small aluminum frames, long-term usage costs are lower (with a lifespan of over 10 years).
Wide Environmental Adaptability

Wide Temperature Range: Stable performance in environments from -30°C to 150°C (special steel can extend the range).

Multiple Ground Adaptability: Mobile models with casters are suitable for flat surfaces, while fixed models can be reinforced with foundations to adapt to uneven terrain.
